    OPINION OF THE COURT
    SLOVITER, Circuit Judge.
    The issue before us is one of preemption, an area of the
    law that need delicately balance federal interests and those of the
    states. It harks back to the very beginning of our republic, and
    has continued to occupy us ever since. Preemption is not a
    doctrine that lends itself to a black-letter rule. One size does not
    fit all. The decision must be based on the circumstances
    presented in the particular situation.
    The plaintiffs in these consolidated cases are the husband
    and daughter, respectively, of two adults who committed suicide
    5
    after taking medication from the class of antidepressants known
    as selective serotonin reuptake inhibitors (“SSRIs”). The
    common question presented by the cases is whether the plaintiffs
    may maintain their state-law tort actions against the
    manufacturers of two such drugs on the theory that the drugs’
    labeling failed to warn of their association with an increased risk
    of suicidality. The central issue is whether actions taken by the
    Food and Drug Administration (“FDA”) pursuant to its authority
    under the Federal Food, Drug, and Cosmetic Act (“FDCA”), 21
    U.S.C. §§ 301-397, and the corresponding regulatory scheme
    preempt the plaintiffs’ state-law failure-to-warn claims.
    I.
    SmithKline Beecham, d/b/a GlaxoSmithKline (“GSK”),
    manufactures Paxil, an SSRI that is used to treat depression. On
    October 6, 2003, Lois Colacicco’s physician prescribed Paxil for
    her depression. After her prescription was filled with a generic
    version of Paxil, Lois Colacicco began taking that medication.
    Less than a month later, on October 28, 2003, at the age of fifty-
    five, she committed suicide in her New York home.
    At the time of Lois Colacicco’s death, the labeling for
    Paxil included the following language in its “Precautions”
    section:
    Suicide: The possibility of a suicide attempt is inherent
    in major depressive disorder and may persist until
    significant remission occurs. Close supervision of high-
    risk patients should accompany initial drug therapy.
    Prescriptions for PAXIL should be written for the
    smallest quantity of tablets consistent with good patient
    management, in order to reduce the risk of overdose . . . .
    Colacicco App. at 436. Apotex, Inc. and Apotex Corp.
    (together, “Apotex”) manufacture and distribute the generic
    version of paroxetine hydrochloride (the active ingredient in
    Paxil) ingested by Lois Colacicco. The labeling for Apotex’s
    generic paroxetine was identical to GSK’s labeling for Paxil.
    6
    After Lois Colacicco’s death, her husband, Joseph C.
    Colacicco, filed suit against Apotex and GSK in the United
    States District Court for the Eastern District of Pennsylvania,
    alleging that those companies violated state common-law tort
    rules and New York state consumer protection laws by selling
    their products with labels that failed to warn consumers of the
    increased risk of emergent suicidality and worsening depression
    in adults taking paroxetine. On May 26, 2006, Apotex and GSK
    moved to have Colacicco’s complaint dismissed on the ground
    that it was preempted by federal law and, alternatively, that GSK
    did not owe a duty of care to the consumers of generic
    paroxetine, such as Lois Colacicco. The District Court
    dismissed the complaint on the basis of preemption. Colacicco
    v. Apotex, Inc., 
    432 F. Supp. 2d 514
    , 537-39 (E.D. Pa. 2006).
    Pfizer is the manufacturer of Zoloft, another SSRI that is
    used to treat depression. On January 22, 2003, sixty-four-year-
    old Theodore DeAngelis was prescribed Zoloft for anxiety and
    depression. DeAngelis ingested that drug in the days leading up
    to his death by suicide on January 30, 2003. At the time of his
    death, the suicide precaution on Zoloft’s labeling read as
    follows:
    Suicide - The possibility of a suicide attempt is inherent
    in depression and may persist until significant remission
    occurs. Close supervision of high risk patients should
    accompany initial drug therapy. Prescriptions for Zoloft
    (sertraline) should be written for the smallest quantity of
    capsules consistent with good patient management, in
    order to reduce the risk of overdose.
    McNellis App. 499-500.
    Following DeAngelis’ death, Beth Ann McNellis, his
    daughter and the executrix of his estate, filed suit in New Jersey
    state court, alleging that Pfizer violated various New Jersey
    products liability and consumer fraud statutes by selling Zoloft
    without warning consumers that it increased the risk of
    suicidality in those ingesting the drug. Pfizer removed the action
    to the United States District Court for the District of New Jersey
    7
    and moved for summary judgment on the ground that McNellis’
    claim was preempted by federal law. The Court denied that
    motion on December 29, 2005. McNellis ex rel. DeAngelis v.
    Pfizer, Inc. (“McNellis I”), No. Civ. 05-1286 (JBS), 
    2005 WL 3752269
    , at *13 (D.N.J. Dec. 29, 2005). On September 29,
    2006, following the dismissal of Colacicco’s complaint in the
    Pennsylvania District Court, the New Jersey District Court
    denied Pfizer’s motion to vacate its denial of the summary
    judgment motion, but certified its order for interlocutory appeal.
    The District Court framed the question for appeal as follows:
    Whether . . . the United States Food and Drug
    Administration’s requirements for the form and content of
    the labeling for the prescription antidepressant Zoloft
    preempted New Jersey’s failure-to-warn law, under the
    doctrine of conflict preemption, where the FDA’s
    regulations at 21 C.F.R. 201.57(e) [(2003)] and
    314.70(c)(6)(iii) [(2007)] permit a manufacturer to
    unilaterally enhance its warning when the manufacturer
    has reasonable evidence of an association of a serious
    hazard with a drug.
    McNellis ex rel. DeAngelis v. Pfizer, Inc. (“McNellis II”), No.
    Civ. 05-1286 (JBS), 
    2006 WL 2819046
    , at *13 n.9 (D.N.J. Sept.
    29, 2006). We must decide which of the two fine opinions
    authored by two of the ablest district judges in this circuit most
    closely expresses our view of the difficult issue presented.
    II.
    The FDA is charged with “promot[ing] the public health
    by promptly and efficiently reviewing [drug manufacturers’]
    clinical research and taking appropriate action on the marketing
    of regulated products in a timely manner” and “protect[ing] the
    public health by ensuring that . . . drugs are safe and effective.”
    21 U.S.C. § 393(b)(1), (b)(2)(B). In this capacity, the FDA
    regulates the introduction of all new drugs. 
    Id. § 355(a).
    Persons intending to market a drug must first file a new drug
    application (“NDA”) with the FDA. 
    Id. § 355(b).
    An NDA
    must include, inter alia, full reports of investigations into the
    8
    drug’s safety and effectiveness, the components and production
    methods used to manufacture the drug, and “specimens of the
    labeling proposed to be used for such drug.” 
    Id. § 355(b)(1);
    see
    also 21 C.F.R. § 314.50(c)(2)(i) (requiring manufacturers to
    include “statements describing the reasons for omitting a section
    or subsection of the labeling format in § 201.57 of this chapter”),
    (e)(2)(ii).
    Although “labeling” may be commonly understood as the
    label affixed to a prescription bottle, in this context it also
    encompasses the written material sent to the physician and
    included with the drug provided to the patient.1 The FDA
    regulations require prescription drug labeling to include “a
    summary of the most clinically significant information . . .
    critical to safe use of the drug,” including, inter alia, potential
    safety hazards associated with use of the drug. 21 C.F.R. §
    201.57a(10), (c)(6)(i). Applicants must also include a “summary
    of the benefits and risks of the drug, including a discussion of
    why the benefits exceed the risks under the conditions stated in
    the labeling.” 
    Id. § 314.50(d)(5)(viii).
    The FDA must deny an NDA if it finds that:
    (1) the investigations [discussed above] do not include
    adequate tests by all methods reasonably applicable to
    show whether or not such drug is safe for use under the
    conditions prescribed, recommended, or suggested in the
    proposed labeling thereof;
    (2) the results of such tests show that such drug is unsafe
    1
    “Labeling” is defined by statute as “all labels and other
    written, printed, or graphic matter (1) upon any article or any of its
    containers or wrappers, or (2) accompanying such article.” 21
    U.S.C § 321(m). Thus, labeling “embraces advertising or
    descriptive matter that goes with the package in which the articles
    are transported,” Kordel v. United States, 
    335 U.S. 345
    , 350
    (1948), in addition to any label that may be placed directly on a pill
    bottle.
    9
    for use under such conditions or do not show that such
    drug is safe for use under such conditions;
    . . . . or
    (7) based on a fair evaluation of all material facts, such
    labeling is false or misleading in any particular.
    21 U.S.C. § 355(d). The FDA shall otherwise approve the NDA.
    
    Id. The “FDA
    will approve an application and issue the
    applicant an approval letter . . . on the basis of draft labeling if
    the only deficiencies in the application concern editorial or
    similar minor deficiencies in the draft labeling.” 21 C.F.R. §
    314.105(b). However, “[s]uch approval will be conditioned
    upon the applicant incorporating the specified labeling changes
    exactly as directed, and upon the applicant submitting to FDA a
    copy of the final printed labeling prior to marketing.” 
    Id. The FDA’s
    post-approval oversight of drug labeling is
    governed primarily by regulation.2 At the times relevant to this
    litigation, 21 C.F.R. § 201.56 described the general requirements
    for the content and format of drug labeling, while 21 C.F.R. §
    201.57 set forth the specific requirements for such labeling.3
    2
    Because many of the relevant regulations were revised or
    relocated after the dates relevant to this litigation (both DeAngelis
    and Lois Colacicco were prescribed SSRIs and committed suicide
    between January and October of 2003), we set forth the regulations
    in effect during that time period in the text and, where applicable,
    provide parallel citations to the current language and location of
    those regulations in footnotes. Unless otherwise noted, the
    substance of the regulations cited in this opinion have remained
    consistent between January of 2003 and the present.
    3
    As part of the FDA’s amendments to its labeling
    regulations in 2006, additional labeling requirements for recently
    approved drugs were added to § 201.56 and that section was
    retitled. See 21 C.F.R. § 201.56 (2007); see also 71 Fed. Reg.
    3922, 3986 (Jan. 24, 2006). Meanwhile, the specific requirements
    relating to drugs introduced prior to the amendments were amended
    and redesignated as § 201.80. See 71 Fed. Reg. at 3988, 3996. Of
    10
    Section 201.57(e) required manufacturers to “describe serious
    adverse reactions and potential safety hazards” under the
    heading “Warnings.” 21 C.F.R. § 201.57(e) (2003). Moreover,
    “[t]he labeling shall be revised to include a warning as soon as
    there is reasonable evidence of an association of a serious hazard
    with a drug; a causal relationship need not have been proved.”
    
    Id. The same
    section states that “[s]pecial problems, particularly
    those that may lead to death or serious injury, may be required
    by the [FDA] to be placed in a prominently displayed box. . . . If
    a boxed warning is required, its location will be specified by the
    [FDA].” 
    Id. FDA regulations
    also govern the procedures for revising
    drug labeling. At all times relevant to this litigation, an
    applicant was required to notify the FDA of any changes to an
    approved drug, including its labeling, by one of three methods,
    depending on the magnitude of the intended change. See §
    314.70(a)-(d) (2003). Section 314.70(b) covered “supplements
    requiring FDA approval before the change is made.” 
    Id. § 314.70(b).
    “Any change in labeling, except one described in
    [subsections] (c)(2) or (d) of this section” required FDA pre-
    approval. 
    Id. § 314.70(b)(3)(i).
    Subsection (d) was limited to
    minor changes that may be submitted with the drug
    manufacturer’s annual report, and is not implicated by this
    litigation. See 
    id. § 314.70(d).
    Subsection (c), however,
    described “changes that may be made before FDA approval.”
    
    Id. § 314.70(c).
    In particular, “[a]n applicant shall submit a
    supplement at the time the applicant makes” a change to its
    labeling “[t]o add or strengthen a contraindication, warning,
    precaution, or adverse reaction.” 
    Id. § 314.70(c)(2)(i).
    The
    supplemental submissions by which § 314.70(c) changes are
    accomplished are sometimes referred to as “changes being
    primary importance to this litigation, the text formerly appearing at
    § 201.57(e) now appears at § 201.80(e). The relevant language
    remains unchanged. Compare 21 C.F.R. § 201.57(e) (2003), with
    21 C.F.R. § 201.80(e) (2007). See also 71 Fed. Reg. at 3996.
    11
    effected” or “CBE” supplements.4
    4
    The FDA also amended § 314.70 in 2006. The regulation
    now refers to changes under subsections (b), (c), and (d) as
    “major,” “moderate,” and “minor” changes, respectively. 21
    C.F.R. § 314.70(b), (c), (d) (2007). For the purposes of this
    litigation, subsections (b) and (d) are not materially different.
    Subsection (c), however, is now titled “Changes requiring
    supplement submission at least 30 days prior to distribution of the
    drug product made using the change (moderate changes).” 
    Id. § 314.70(c).
    Nonetheless, that subsection also states that the FDA
    “may designate a category of changes for the purpose of providing
    that, in the case of a change in such category, the holder of an
    approved application may commence distribution of the drug
    product involved upon receipt by the agency of a supplement for
    the change.” 
    Id. § 314.70(c)(6).
    The listed categories include
    changes in labeling “[t]o add or strengthen a contraindication,
    warning, precaution, or adverse reaction.”                    
    Id. § 314.70(c)(6)(iii)(A).
    Thus, for all practical purposes, subsection
    (c)(2)(i) has simply been relocated to subsection (c)(6)(iii)(A), but
    the FDA may determine that products incorporating such labeling
    changes may not be distributed until the agency has received the
    CBE supplement or thirty days thereafter. Finally, the FDA now
    provides express notice that if it “disapproves the supplemental
    application, it may order the manufacturer to cease distribution of
    the drug product(s) made with the manufacturing change.” 
    Id. § 314.70(c)(7).
    After oral argument, the FDA submitted a proposed rule that
    would further limit the type of changes that may be effected
    pursuant to § 314.70(c)(6)(iii). See 73 Fed. Reg. 2848 (Jan. 16,
    2008). Specifically, that regulation would be limited to: “Changes
    in the labeling to reflect newly acquired information, except for
    changes to the information required in § 201.57(a) of this chapter
    (which must be made under paragraph (b)(2)(v)(C) of this section),
    to accomplish any of the following: (A) To add or strengthen a
    contraindication, warning, precaution, or adverse reaction for
    which the evidence of a causal association satisfies the standard for
    inclusion in the labeling under 201.57(c) of this chapter . . . .” 73
    12
    Drug manufacturers have continuing obligations to report
    adverse drug experiences, 
    id. § 314.80(c),
    and any “significant
    new information . . . that might affect the safety, effectiveness,
    or labeling of the drug product,” 
    id. § 314.81(b)(2)(i).
    Failure to
    abide by these obligations may result in withdrawal of an
    approved drug. 
    Id. §§ 314.80(j),
    314.81(d).
    Although regulations describe the particulars of the
    FDA’s oversight of drug labeling, the FDCA describes the
    primary penalties for a drug manufacturer’s failure to comply
    with those regulations. The FDA must withdraw approval of a
    drug if it finds “on the basis of new information before [it,] . . .
    that there is a lack of substantial evidence that the drug will have
    the effect it purports or is represented to have under the
    conditions of use prescribed, recommended, or suggested in the
    labeling thereof.” 21 U.S.C. § 355(e). The FDA may withdraw
    approval of a drug if, “on the basis of new information before
    [it,] . . . the labeling of such drug, based on a fair evaluation of
    all material facts, is false or misleading in any particular and was
    not corrected within a reasonable time after receipt of written
    notice from the [FDA] specifying the matter complained of.” 
    Id. The distribution
    of “misbranded” drugs is also prohibited
    by the FDCA. 
    Id. § 331(a),
    (b). A drug is misbranded if its
    “labeling is false or misleading in any particular,” 
    id. § 352(a),
    if
    its labeling lacks “adequate warnings against use . . . where its
    use may be dangerous to health,” 
    id. § 352(f),
    or if “it is
    dangerous to health when used in the . . . manner . . . prescribed,
    recommended, or suggested in the labeling thereof,” 
    id. § 352(j).
    The FDA has the authority to enforce the prohibition on
    misbranding by initiating injunction proceedings, see 
    id. § 332,
    criminal prosecutions, see 
    id. § 333(a),
    and the seizure of
    misbranded drugs, see 
    id. § 334.
    Once a drug has been approved, it is included in the
    FDA’s published list of approved drugs. See 21 U.S.C. §
    Fed. Reg. at 2853.
    13
    355(j)(7). Such a drug is then referred to as a “listed drug.” 
    Id. § 355(j)(2)(A)(i).
    A listed drug is sometimes also referred to as
    an “innovator” or “pioneer” drug. See, e.g., Bristol-Myers
    Squibb Co. v. Shalala, 
    91 F.3d 1493
    , 1494, 1497-98 (D.C. Cir.
    1996). Although the manufacturers of listed drugs, such as GSK
    and Pfizer in this case, are governed by all of the requirements
    associated with NDAs, the manufacturers of generic drugs, such
    as Apotex, are not required to submit an NDA. Rather, such
    manufacturers must abide by certain statutes and regulations that
    are based on the equivalence of generic drugs to the listed drugs.
    The Drug Price Competition and Patent Term Restoration
    Act of 1984 (the Hatch-Waxman Amendments) relaxed the
    approval procedures for generic drug manufacturers, allowing
    them to submit an abbreviated NDA (“ANDA”). Pub. L. No.
    98-417, 98 Stat. 1585 (codified at 21 U.S.C. § 355(j), 35 U.S.C.
    §§ 156, 271, 281). An ANDA must contain information
    showing the generic drug’s bioequivalency to the listed drug and
    that “the labeling proposed for the new drug is the same as the
    labeling approved for the listed drug . . . .” 21 U.S.C. §
    355(j)(2)(A)(iv) & (v).5 FDA regulations also provide that the
    agency may seek withdrawal of a generic drug, pursuant to
    notice and the opportunity for a hearing, if “the labeling for the
    [generic drug] is no longer consistent with that for the listed drug
    referred to in the [ANDA].” 21 C.F.R. § 314.150(b)(10).
    III.
    The District Courts had jurisdiction over the plaintiffs’
    claims under 28 U.S.C. § 1332. We have jurisdiction over
    Colacicco’s appeal pursuant to 28 U.S.C. § 1291 following the
    entry of the order of the Pennsylvania District Court dismissing
    Colacicco’s complaint; we have jurisdiction over Pfizer’s appeal
    from the New Jersey District Court’s interlocutory order denying

    The FDA states that generic drug manufacturers may not
    add new warnings to the approved labeling for the listed drug. 57

    because the District Court certified that order pursuant to 28
    U.S.C. § 1292(b).
    The issue underlying the District Courts’ orders presents a
    question of law. We apply plenary review over their preemption
    determinations. See Pennsylvania Employees Benefit Trust
    Fund v. Zeneca Inc., 
    499 F.3d 239
    , 242 (3d Cir. 2007) (motion
    to dismiss); Horn v. Thoratec Corp., 
    376 F.3d 163
    , 166 (3d Cir.
    2004) (motion for summary judgment).
    IV.
    The doctrine of preemption is rooted in the Supremacy
    Clause, U.S. Const. art. VI, cl. 2, which provides that the
    “Constitution, and the Laws of the United States which shall be
    made in Pursuance thereof . . . shall be the supreme Law of the
    Land.” Early in our constitutional history, the Supreme Court
    interpreted this language to invalidate state laws that “interfere
    with, or are contrary to,” federal law, the genesis of the
    preemption doctrine. Gibbons v. Ogden, 22 U.S. (9 Wheat.) 1,
    211 (1824). The Supreme Court has identified three major
    situations where there is preemption. They were described in
    Hillsborough County v. Automated Med. Labs., Inc. as: (1)
    “express” preemption, applicable when Congress expressly
    states its intent to preempt state law; (2) “field” preemption,
    applicable when “Congress’ intent to pre-empt all state law in a
    particular area may be inferred [because] the scheme of federal
    regulation is sufficiently comprehensive” or “‘the federal interest
    is so dominant that the federal system will be assumed to
    preclude enforcement of state laws on the same subject;’” and
    (3) “conflict” preemption, applicable when “state law is nullified
    to the extent that it actually conflicts with federal law,” even
    though Congress has not displaced all state law in a given area.6
    6
    Both field and conflict preemption are sometimes referred
    to as forms of implied preemption. See, e.g., Geier v. Am. Honda
    Motor Co., 
    529 U.S. 861
    , 884 (2000); Freightliner Corp. v. Myrick,
    
    514 U.S. 280
    , 287 (1995). However, the Supreme Court has also
    15
    
    471 U.S. 707
    , 713 (1985) (quoting Rice v. Santa Fe Elevator
    Corp., 
    331 U.S. 218
    , 230 (1947)).
    An express preemption situation is exemplified by the
    Supreme Court’s recent decision in Riegel v. Medtronic, Inc., ---
    U.S. ----, 
    128 S. Ct. 999
    (2008), where it considered the effect of
    the express preemption provision of the Medical Device
    Amendments of 1976 (“MDA”) to the FDCA.7 It held that in
    light of that provision, plaintiffs’ claims that an arterial catheter
    was designed, labeled, and manufactured in a way that violated
    New York common law were preempted. 
    Id. at 1003,
    1005,
    1011. See also 
    Horn, 376 F.3d at 166
    .
    In the Colacicco case, the Pennsylvania District Court
    noted that GSK and Apotex conceded that express and field
    preemption are not implicated, and proceeded exclusively under
    a conflict preemption 
    analysis. 432 F. Supp. 2d at 523
    . After
    reviewing the applicable principles and relevant precedent, and
    according considerable deference to the FDA’s position, the
    Court held that Colacicco’s claims are preempted. 
    Id. at 537-38.
    In so holding, the Court rejected Colacicco’s argument that the
    asserted that these three categories are not “rigidly distinct;” for
    example, “field pre-emption may be understood as a species of
    conflict preemption: A state law that falls within a pre-empted field
    conflicts with Congress’ intent (either express or plainly implied)
    to exclude state regulation.” English v. Gen. Elec. Co., 
    496 U.S. 72
    , 79-80 n.5 (1990).
    7
    The statutory language provides that:
    no State or political subdivision of a State may establish or
    continue in effect with respect to a device intended for
    human use any requirement (1) which is different from, or
    in addition to, any requirement applicable under [the MDA]
    to the device, and (2) which relates to the safety or
    effectiveness of the device or to any other matter included
    in a requirement applicable to the device under [the Act].
    21 U.S.C. § 360(k)(a).
    16
    FDA’s position should not be accorded deference because it was
    inconsistent with the FDA’s prior statements. The Court
    concluded that “after 2000, the FDA has been very consistent.”
    
    Id. at 531-32.
    A directly contrary conclusion was reached by the New
    Jersey District Court in the McNellis case. In the first of two
    opinions on the issue, the Court denied defendant Pfizer’s
    motion for summary judgment, holding that it was unwilling to
    find that Congress intended to obviate the state laws upon which
    McNellis’ complaint was based. McNellis I, 
    2005 WL 3752269
    ,
    at *10. The Court held that discovery was needed on whether
    Pfizer had reasonable evidence of an association between Zoloft
    and suicidality. 
    Id. at *11.
    In its opinion the following year, the
    Court declined to vacate its earlier opinion, and instead
    determined that “there can be no conflict preemption because the
    FDA’s regulations do not conflict with New Jersey’s failure to
    warn laws.” McNellis II, 
    2006 WL 2819046
    , at *5. The Court
    held that the interpretation of the FDA was not entitled to the
    substantial deference accorded by the Pennsylvania District
    Court, and certified its order to this court for interlocutory
    appeal. 
    Id. at *10,
    *13.
    The pharmaceutical companies do not seriously argue that
    this is a case of express preemption 8 or field preemption. We
    8
    Apotex and GSK briefly argue that this is a case of express
    preemption because the 1962 Amendments to the FDCA stated:
    “Nothing in the amendments made by this Act to the [FDCA] shall
    be construed as invalidating any provision of State law which
    would be valid in the absence of such amendments unless there is
    a direct and positive conflict between such amendments and such
    provision of State law.” Drug Amendments of 1962, Pub. L. No.
    87-781, § 202, 76 Stat. 780, 793 (Oct. 10, 1962). Of course, the
    plain language of this provision states that the Amendments do not
    preempt state law in the absence of a conflict. Thus, to the extent
    that this provision affects our analysis, it merely states that conflict
    preemption applies. In other words, this “express preemption”
    provision simply leads us to a conflict preemption analysis, which
    17
    therefore limit our consideration to whether the plaintiffs’ state-
    law claims conflict with the federal scheme.
    A.
    We consider first whether there is a presumption against
    preemption applicable in this case. The existence vel non of
    such a presumption is contested. The Supreme Court has stated:
    “[i]n all pre-emption cases, and particularly in those in which
    Congress has legislated in a field which the States have
    traditionally occupied, we start with the assumption that the
    historic police powers of the States were not to be superseded by
    the Federal Act unless that was the clear and manifest purpose of
    Congress.” Medtronic, Inc. v. Lohr, 
    518 U.S. 470
    , 485 (1996)
    (hereafter referred to as “Lohr”) (citation, internal quotation
    marks, and alterations omitted). Colacicco and McNellis
    emphasize this “presumption against preemption,” and both
    District Courts recognized the existence of that presumption.
    See 
    Colacicco, 432 F. Supp. 2d at 524
    ; McNellis I, 
    2005 WL 3752269
    , at *3. Although a presumption against preemption is
    commonly acknowledged, the Supreme Court has made clear
    that the application of such a presumption is not always
    appropriate. See Buckman Co. v. Plaintiffs’ Legal Comm., 
    531 U.S. 341
    , 347-48 (2001) (declining to apply a presumption
    against preemption where the plaintiff alleged fraud on the
    FDA).
    Apotex and GSK argue that a presumption against
    preemption does not apply in the circumstances presented here
    because the states have not traditionally been involved in the
    regulation of drug labeling, whereas the federal government has
    regulated that area for over a hundred years. Pfizer takes an
    even broader position, arguing that the presumption against
    preemption does not apply at all in conflict preemption cases.9
    may be applied independently of an express preemption analysis.
    9
    Pfizer also argues that it has overcome the presumption
    were it applicable. Where appropriate, we have not hesitated to find
    a conflict even after applying the presumption against preemption.
    18
    The Supreme Court’s decision in Hillsborough County
    undermines both of these arguments. In that case, the Court
    stated that the “presumption that state or local regulation of
    matters related to health and safety is not invalidated under the
    Supremacy 
    Clause,” 471 U.S. at 715
    , and then proceeded to
    analyze whether local regulations imposed on blood plasma
    centers “conflict with the federal scheme,” 
    id. at 720.
    The Court
    concluded that the County’s ordinances and regulations, which
    imposed donor testing and requirements beyond those contained
    in the federal regulations, and which were designed to protect
    the health of the donors, to ensure the quality of the plasma, and
    to protect the recipients of the plasma, 
    id. at 715-16,
    were not
    preempted by the federal regulatory scheme because the
    County’s requirements “do not imperil the federal goal of
    ensuring sufficient plasma,” 
    id. at 722.
    The Supreme Court later addressed the presumption
    against preeemption in Lohr, where the plaintiff, who was
    injured by the failure of her pacemaker, filed a “common-law
    negligence action against the manufacturer of an allegedly
    defective medical 
    device.” 518 U.S. at 474
    . The manufacturer
    argued that the claim was preempted by a provision in the MDA
    that bars state or local requirements different from those
    applicable under the MDA and which relate to the safety or
    effectiveness of any device covered by the Act.10 
    Id. at 481.
    The Court referred to the states’ police powers to protect the
    health and safety of their citizens, 
    id. at 485,
    the premise of the
    presumption against preemption, in holding that plaintiff’s
    negligence action was not preempted. A plurality of the Court
    noted that the statutory language precluded any additional
    “requirement,” not any “remedy,” under state law, 
    id. at 487,
    and
    concluded, by reference to the legislative history, that the statute
    “was not intended to pre-empt most, let alone all, general
    common-law duties enforced by damages actions.” 
    Id. at 491.
    We note, however, that the Court did not discuss the
    See Fasano v. Fed. Reserve Bank of New York, 
    457 F.3d 274
    , 283,
    290 (3d Cir. 2006).
    10
    See supra note 7.
    19
    presumption against preemption in its recent opinion in Riegel
    considering the same provision of the MDA at issue in Lohr.
    There are, as the pharmaceutical companies argue,
    relevant Supreme Court decisions where the Court explicitly
    declined to apply any presumption against preemption. In
    Buckman, plaintiffs, who claimed injuries from the use of
    orthopedic bone screws, brought suit against the consultant to
    the manufacturer on the theory that its statements defrauded the
    FDA and led the agency to approve a device that caused the
    plaintiffs’ injuries. 
    See 531 U.S. at 343
    , 347-48. The Supreme
    Court held that plaintiffs’ fraud claims were preempted. It
    rejected plaintiffs’ argument that there was a “virtually
    irrefutable presumption against implied preemption of private
    damage remedies predicated on an alleged conflict with a federal
    remedial scheme.” 
    Id. at 351
    (internal quotation marks omitted).
    Because “the relationship between a federal agency and the
    entity it regulates . . . originates from, is governed by, and
    terminates according to federal law,” the Court concluded that
    the plaintiffs’ claims did not implicate the traditional state
    interest in the regulation of public health and safety, and thus it
    did not apply the presumption against preemption. 
    Id. at 347-48.
    Similarly, in United States v. Locke, 
    529 U.S. 89
    , 94, 108
    (2000), the Supreme Court considered whether Washington State
    laws governing oil tanker operations and designs enacted after
    the oil spill caused by the Exxon Valdez were preempted by a
    comprehensive federal regulatory scheme governing oil tankers.
    The Court declined to apply a presumption against preemption
    because the case concerned “national and international maritime
    commerce,” a field in which “Congress has legislated . . . from
    the earliest days of the Republic.” 
    Id. The Court
    noted that “an
    ‘assumption’ of nonpre-emption is not triggered when the State
    regulates in an area where there has been a history of significant
    federal presence.” 
    Id. While the
    decisions in Buckman and Locke are
    distinguishable from the cases before us, they do make clear that
    it is “the purpose of Congress [as] the ultimate touchstone of
    pre-emption analysis,” Cipollone v. Liggett Group, Inc., 505
    
    20 U.S. 504
    , 516 (1992) (citations, internal quotation marks, and
    alterations omitted), to which we must turn. See also 
    Rice, 331 U.S. at 230
    ; Fasano v. Fed. Reserve Bank of New York, 
    457 F.3d 274
    , 284 (3d Cir. 2006). Colacicco and McNellis argue
    that preemption is inappropriate because Congress has never
    expressed its intent to preempt state-law tort actions challenging
    drug labeling. McNellis notes that the New Jersey District Court
    concluded that it was “unwilling to find . . . that Congress
    intended to obviate the very state laws that provide remedies to
    consumers harmed by dangerous products and deceptive
    marketing in the absence of a clear and compelling
    Congressional statement.” McNellis I, 
    2005 WL 3752269
    , at *10
    (citing Bates v. Dow Agrosciences LLC, 
    544 U.S. 431
    , 450
    (2005)).
    The pharmaceutical companies respond by quoting the
    Supreme Court’s statement that “in a situation where state law is
    claimed to be pre-empted by federal regulation, a ‘narrow focus
    on Congress’ intent to supersede state law [is] misdirected,’ for
    ‘[a] pre-emptive regulation’s force does not depend on express
    congressional authorization to displace state law.’” City of New
    York v. FCC, 
    486 U.S. 57
    , 64 (1988) (quoting Fid. Fed. Sav. &
    Loan Ass’n v. de la Cuesta, 
    458 U.S. 141
    , 154 (1982)). In fact,
    the Supreme Court has found that even where an express
    preemption saving clause demonstrated Congress’ intent to
    exempt common-law tort actions from preemption, the language
    of the saving clause did not suggest an intent to “bar the ordinary
    working of conflict pre-emption principles” or preserve
    “state-law tort actions that conflict with federal regulations.”
    Geier v. Am. Honda Motor Co., 
    529 U.S. 861
    , 869 (2000). The
    Court held that federal regulations may preempt common-law
    tort actions under a conflict preemption analysis despite a
    statutory provision stating that “‘[c]ompliance with’ a federal
    safety standard ‘does not exempt any person from any liability
    under common law.’” 
    Id. at 868
    (quoting 15 U.S.C. § 1397(k)
    (1988 ed.)). Thus, the Court concluded that plaintiff’s tort action
    against the automobile manufacturer for failing to install airbags
    was preempted under conflict preemption principles although
    expressly saved from preemption by statute. 
    Id. at 881.
    21
    It follows that in this case, which is also one of conflict
    preemption, the lack of a Congressional directive expressly
    approving or rejecting preemption in the context of drug labeling
    regulations is not determinative. Rather, the conflict preemption
    analysis is designed to determine the propriety of preemption
    where Congress has not explicitly stated its intent. Seen in this
    light, Pfizer’s argument that the presumption against preemption
    is inapplicable in the context of implied conflict preemption has
    more force. Although the Supreme Court applied the
    presumption in Hillsborough County, a decision in which it
    engaged in a conflict preemption analysis, that analysis followed
    the Court’s consideration of field preemption 
    principles. 471 U.S. at 716-20
    .11 Therefore, the extent to which the Court relied
    on the presumption in the context of its conflict analysis is not
    clear. Here, we recognize the applicability of the presumption
    against preemption, but note the tension between such a
    presumption, which emphasizes the “clear and manifest purpose
    of Congress,” 
    Lohr, 518 U.S. at 485
    (internal quotation marks
    omitted), and implied conflict preemption, which analyzes
    preemption in the absence of any explicit intent, cf. 
    Geier, 529 U.S. at 885
    (failing to formally apply the presumption against
    preemption, but “assum[ing] that Congress or an agency
    ordinarily would not intend to permit a significant conflict”).
    B.
    A conflict between state and federal law “arises when
    compliance with both federal and state regulations is a physical
    impossibility or when state law stands as an obstacle to the
    accomplishment and execution of the full purposes and
    11
    Although both field and conflict preemption are generally
    thought of as forms of implied preemption, a focus on
    Congressional intent is of greater value in the context of field
    preemption, where Congress’ mere presence in a given field
    indiscriminately nullifies all state law in the field, than in the
    context of conflict preemption, which excludes state law only to the
    extent that it requires individuals to act contrary to conflicting
    federal obligations.
    22
    objectives of Congress.” Hillsborough 
    County, 471 U.S. at 713
    (citations and internal quotation marks omitted); see also City of
    New 
    York, 486 U.S. at 64
    (“The statutorily authorized
    regulations of an agency will pre-empt any state or local law that
    conflicts with such regulations or frustrates the purposes
    thereof.”).
    There are not many examples of instances where it is
    impossible to comply with both federal and state law,
    presumably because state legislatures and regulators do not
    readily seek confrontation with federal authority. One such
    example is provided by the Court’s 1913 decision where it
    considered the effect of a 1907 Wisconsin statute providing that
    mixtures or syrups offered for sale “shall have upon them no
    designation or brand . . . other than that required by the state law
    . . . .” McDermott v. Wisconsin, 
    228 U.S. 115
    , 127 (1913). The
    federal food and drugs act passed in 1906 barred false and
    misleading labels on product packages. 
    Id. at 127,
    129. When
    the issue came before the Supreme Court, it stated that “the State
    may not, under the guise of exercising its police power or
    otherwise, . . . enact legislation in conflict with the statutes of
    Congress passed for the regulation of the subject . . . .” 
    Id. at 131-32.
    The Court held that the state statute was invalid because
    “[t]he legislative means provided in the Federal law for its own
    enforcement may not be thwarted by state legislation having a
    direct effect to impair the effectual exercise of such means.” 
    Id. at 137.
    The scarcity of actual conflict cases has led the Justices to
    pose hypothetical conflicts. In Florida Lime & Avocado
    Growers, Inc. v. Paul, 
    373 U.S. 132
    , 143 (1963), the Supreme
    Court hypothesized the existence of an impossibility conflict
    where “federal orders forbade the picking and marketing of any
    avocado testing more than 7% oil, while the California test
    excluded from the State any avocado measuring less than 8% oil
    content.” Under those circumstances, it would be a “physical
    impossibility” for avocado growers to comply with both federal
    and state law because California law would require them to do
    what federal law forbade, that is, pick their avocados after they
    surpassed the 7% ceiling established by federal law. 
    Id. 23 In
    another case, where the issue was whether a federal
    statute that permits national banks to sell insurance in small
    towns preempts a state statute that forbids them to do so, Justice
    Breyer discussed the impossibility situation:
    In this case we must ask whether or not the Federal and
    State Statutes are in “irreconcilable conflict.” The two
    statutes do not impose directly conflicting duties on
    national banks-as they would, for example, if the federal
    law said, “you must sell insurance,” while the state law
    said, “you may not.”
    Barnett Bank of Marion County, N.A. v. Nelson,

    , 31
    (1996).
    Most of the preemption cases falling within the conflict
    category are cases that present the second scenario discussed in
    Hillsborough County - when “state law stands as an obstacle to
    the accomplishment and execution of the full purpose and
    objectives of 
    Congress.” 471 U.S. at 713
    (internal quotation
    marks omitted). In his opinion in Barnett Bank, Justice Breyer
    continued,
    the Federal Statute authorizes national banks to engage in
    activities that the State Statute expressly forbids. Thus,
    the State’s prohibition of those activities would seem to
    “stan[d] as an obstacle to the accomplishment” of one of
    the Federal Statute’s purposes – unless, of course, that
    federal purpose is to grant the bank only a very limited
    permission, that is, permission to sell insurance to the
    extent that state law also grants permission to do 
    so. 517 U.S. at 31
    (quoting Hines v. Davidowitz, 
    312 U.S. 52
    , 67
    (1941)). After deciding that the McCarran-Ferguson Act anti-
    preeemption rule did not govern the case, 
    id. at 38,
    the Court
    held that the federal statute preempted the state statute, 
    id. at 42.
    It is not only state statutes that may stand as obstacles to
    the achievement of federal objectives. It is now established that
    law suits based on state tort law, as well as on state statutes, may
    24
    be viewed as presenting obstacles to the federal objectives and
    hence barred as preempted. In Geier, the Court held that an
    action against American Honda based on its failure to provide a
    driver’s side airbag was preempted by a federal regulation. The
    Court adopted the principle that ordinary preemption principles
    apply to a state tort action where an actual conflict with a federal
    objective is at stake. 
    Geier, 529 U.S. at 871-72
    . The majority
    stated that in the absence of such a principle:
    state law could impose legal duties that would conflict
    directly with federal regulatory mandates, say, by
    premising liability upon the presence of the very
    windshield retention requirements that federal law
    requires. See, e.g., 49 CFR § 571.212 (1999). Insofar as
    petitioners’ argument would permit common-law actions
    that “actually conflict” with federal regulations, it would
    take from those who would enforce a federal law the very
    ability to achieve the law’s congressionally mandated
    objectives that the Constitution, through the operation of
    ordinary pre-emption principles, seeks to protect. To the
    extent that such an interpretation of the saving provision
    reads into a particular federal law toleration of a conflict
    that those principles would otherwise forbid, it permits
    that law to defeat its own objectives, or potentially, as the
    Court has put it before, to “‘destroy itself.’”
    
    Id. (quoting Am.
    Tel. & Tel. Co. v. Cent. Office Tel., Inc., 
    524 U.S. 214
    , 228 (1998)).
    A similar consideration was noted in Lohr where Justice
    Breyer, in his separate opinion concurring in part and dissenting
    in part, stated that “ordinarily, insofar as [federal law] pre-empts
    a state requirement embodied in a state statute, rule, regulation,
    or other administrative action, it would also pre-empt a similar
    requirement that takes the form of a standard of care or behavior
    imposed by a state-law tort 
    action.” 518 U.S. at 504-05
    . In
    Horn, which dealt with the same express preeemption provision
    as in Lohr, we quoted from the FDA’s letter brief stating, inter
    alia,
    25
    State common law tort actions threaten the statutory
    framework for the regulation of medical devices,
    particularly with regard to FDA’s review and approval of
    product labeling. State actions are not characterized by
    centralized expert evaluation of device regulatory issues.
    Instead, they encourage, and in fact require, lay judges
    and juries to second-guess the balancing of benefits and
    risks of a specific device to their intended patient
    population - the central role of FDA - sometimes on
    behalf of a single individual or group of 
    individuals. 376 F.3d at 178
    .
    State common-law tort actions based on the
    manufacturers’ failure to warn present the pharmaceutical
    manufacturers with particular difficulties. State standards of
    care undoubtedly differ from state to state. Absent a
    determination that the FDA-approved labeling and the FDA’s
    refusal to require the warnings suggested by plaintiffs in this
    case preempt state tort actions, the manufacturers may be
    subjected to considerable liability based on varying standards,
    with no benchmark that they should follow.
    In holding the tort action based on the failure to provide
    airbags was preempted, the Court in Geier reviewed the history
    of the consideration of passive restraints by the federal agency,
    there the Department of Transportation. Similarly, in this case,
    before we can hold that a federal regulation or, as in Geier, the
    failure to regulate as extensively as plaintiffs sought, has
    preemptive force, we must review the record of the FDA’s
    treatment of the desired warning at issue here.
    As discussed above, a new drug may not be marketed
    until it has received FDA approval. The FDA will not approve a
    drug if its “labeling is false or misleading in any particular.” 21
    U.S.C. § 355(d)(7). Even after a drug has been approved, a drug
    will be deemed misbranded if the “labeling is false or misleading
    in any particular” and the FDA may withdraw approval of that
    drug and prosecute the manufacturer. See 
    id. §§ 331(b)
    (prohibition on misbranding), 355(e)(3) (withdrawal authority),
    26
    352(a), (f), (j) (definition of misbranding), 332 (injunction
    proceedings), 333(a) (criminal prosecutions), 334 (seizure).
    Thus, the FDCA vests the FDA with significant authority over
    drug labeling. FDA regulations further implement this authority.
    Under its regulations, the FDA may withdraw approval of
    a drug if the manufacturer disregards its obligation to submit
    periodic reports notifying the FDA of adverse drug experiences
    and other new information that might affect the drug labeling.
    21 C.F.R. §§ 314.80(c), (j), 314.81(b)(2)(i), (d). FDA
    regulations detail the information that must be included in the
    warnings section of drug labeling and instruct that such “labeling
    shall be revised to include a warning as soon as there is
    reasonable evidence of an association of a serious hazard with a
    drug . . . .” 
    Id. § 201.57(e)
    (2003); 
    id. § 201.80(e)
    (2007).
    There are three distinct procedures by which
    manufacturers may revise their drugs’ labeling, each of which
    requires the manufacturer to notify the FDA of its proposed
    revision. See 
    id. § 314.70(a)-(d).
    Generally, labeling changes
    require FDA pre-approval. See 
    id. § 314.70(b)(3)(i)
    (2003).
    However, changes that “add or strengthen a contraindication,
    warning, precaution or adverse reaction,” may be implemented
    prior to the manufacturer’s receipt of FDA approval. 
    Id. § 314.70(c)(2)(i)
    (2003); 
    id. § 314.70(c)(6)(iii)(A)
    (2007).
    Colacicco and McNellis argue that because § 314.70(c)
    allows drug manufacturers to strengthen and augment warnings
    on drug labeling without prior FDA approval, the FDA labeling
    requirements constitute mere minimum standards for the
    information that may be required in their labeling. See, e.g.,
    Sprietsma v. Mercury Marine, 
    537 U.S. 51
    , 58-59 (2002).
    Therefore, they argue that state-law failure-to-warn claims that
    would require manufacturers to strengthen or augment a warning
    do not conflict with FDA regulations, and are in fact
    complementary to those regulations.
    The pharmaceutical companies respond that even though
    labeling changes made pursuant to § 314.70(c) do not require
    prior approval, the legality of those changes remains within the
    27
    FDA’s control. They state that because the FDA is directly
    involved with balancing the benefits and risks of a drug’s
    labeling, see, e.g., 21 C.F.R. § 314.50(d)(5)(viii), and has the
    statutory authority to order the manufacturer to discontinue
    distribution of any products incorporating the manufacturer’s
    labeling change, the FDA-approved labeling reflects the FDA’s
    expert judgment about the information that must be included in a
    drug’s labeling.12
    Of course, in this case we must focus on the effect of the
    FDA’s failure to require a warning that plaintiffs argue was the
    cause of their injury rather than the effect of a positive
    regulation. It is always easier to evaluate the effect of a conflict
    created by a positive regulation than the effect created by
    inaction. It is difficult to know whether the absence of a
    regulation may reflect a wait-and-see approach or mere inertia.
    We are guided to some extent by Geier where the Court held that
    the failure of the Department of Transportation to require auto
    manufacturers to equip their 1997 vehicles with a specific form
    of passive restraint system, i.e. airbags, preempted the state “no
    airbag” tort 
    suit. 529 U.S. at 874
    , 881.
    In this case we need not speculate on the rationale of the
    FDA for its failure to require the adult suicidality warnings. Not
    only has the FDA filed an amicus brief in the Colacicco action
    but it has repeatedly rejected the scientific basis for the warnings
    that Colacicco and McNellis argue should have been included in
    the labeling. The FDA has actively monitored the possible
    association between SSRIs and suicide for nearly twenty years,13
    12
    Apotex, for its part, argues that tort actions against generic
    drug manufacturers are preempted because the Hatch-Waxman
    Amendments and the FDA’s implementing regulations require such
    manufacturers to maintain labeling identical to that of the innovator
    drug.
    13
    Colacicco, whose complaint was dismissed prior to
    discovery, argues that the District Court improperly relied on
    evidence of the FDA’s past actions and that we are prohibited from
    considering that information. This problem does not arise in the
    28
    and has concluded that the suicide warnings desired by plaintiffs
    are without scientific basis and would therefore be false and
    misleading.
    In 1991, after considering whether antidepressants caused
    or intensified suicidal thoughts, the FDA’s
    Psychopharmacological Drugs Advisory Committee concluded
    that no such warning should be added to Prozac (an SSRI similar
    to Paxil and Zoloft) or other antidepressants. The FDA
    specifically rejected citizen petitions in 1991, 1992, and 1997
    which sought to either withdraw approval of Prozac as a result of
    its asserted association with suicide or to include a suicide
    warning on the labeling of that drug. In each instance, the FDA
    concluded that there was insufficient evidence to take the actions
    requested.
    DeAngelis committed suicide on January 22, 2003. The
    FDA approved the Zoloft suicide precaution seven separate
    times before and after that date, in each instance requiring Pfizer
    to market the drug with the precise labeling approved.14 Further,
    McNellis case, which is before us following summary judgment
    proceedings. Of course, courts may place limited reliance on
    public records in the context of a motion to dismiss. See Anspach
    ex rel. Anspach v. City of Philadelphia, Dep’t of Pub. Health, 
    503 F.3d 256
    , 273 n.11 (3d Cir. 2007). Thus, in Anspach, we took
    notice of FDA public records “not for the truth of [their] contents,
    but rather as evidence of the information provided by the federal
    government” to the relevant regulated parties. 
    Id. Our recognition
    of the records contested here, all of which are publicly available,
    is similarly limited. See also Jean Alexander Cosmetics, Inc. v.
    L’Oreal USA, Inc., 
    458 F.3d 244
    , 256 n.5 (3d Cir. 2006)
    (recognizing that courts may take judicial notice of prior judicial
    proceedings).

    The FDA first approved Zoloft for the treatment of
    depression in adults on December 30, 1991, conditioning its
    approval on Pfizer’s incorporation of specifically indicated labeling
    revisions. In 1996, the FDA approved Zoloft for a new indication,
    the treatment of obsessive compulsive disorder (“OCD”), with that
    29
    just months before DeAngelis’ death, the FDA filed an amicus
    brief in an action before the Court of Appeals for the Ninth
    Circuit, stating that it had concluded that there was no scientific
    basis for a warning suggesting that Zoloft causes suicidality.
    See Brief for the United States as Amicus Curiae, Motus v.
    Pfizer Inc., 
    358 F.3d 659
    (9th Cir. 2004) (Nos. 02-55372, 02-
    55498), 
    2002 WL 32303084
    (brief submitted September 10,
    2002).15
    The FDA also repeatedly approved the Paxil labeling in
    effect at the time of Lois Colacicco’s prescription of Paxil on
    October 6, 2003, and her death on October 28, 2003, approving
    it for a new indication, the treatment of generalized anxiety
    approval again conditioned on Pfizer’s incorporation of a series of
    labeling revisions. The FDA proceeded to approve the use of
    Zoloft for panic disorder and pediatric OCD in 1997, post-
    traumatic stress disorder in 1999, premenstrual dysphoric disorder
    in 2002, and, on February 7, 2003, social anxiety disorder. Each
    time the FDA approved Zoloft for a new indication, it required that
    the final printed labeling be identical to the labeling attached to the
    FDA’s approval.
    15
    The New Jersey District Court acknowledged the FDA’s
    position in Motus, but decided that it was not appropriate to defer
    to that litigation position. See McNellis I, 
    2005 WL 3752269
    , at
    *10. However, we distinguish between the agency’s legal position
    in its amicus brief and its factual representations. In the Motus
    brief, the FDA stated not just its legal conclusions with respect to
    the applicability of preemption, but it also reported its view of the
    state of scientific research regarding Zoloft and antidepressants at
    that time. The FDA’s summary of its scientific determinations
    must be distinguished from the agency’s construction of a statute,
    as the review of scientific information is strictly within its
    expertise. The FDA asserted facts in support of its legal position,
    and we take notice of its statement of those facts, rather than its
    legal position.

    disorder, just a year before those events.16 The FDA approved
    Apotex’s application to market generic paroxetine on June 30,
    2003, concluding that “the drug is safe and effective for use as
    recommended in the submitted labeling,” which included the
    suicide precaution discussed above, rather than a warning. See
    Letter from Gary Buehler, Director, Office of Generic Drugs,
    Center for Drug Evaluation and Research, FDA, to Apotex Corp.

    http://www.fda.gov/cder/foi/appletter/2003/75356ap.pdf (last
    visited January 8, 2008). Significantly, on June 19, 2003, the
    FDA issued a public statement to address reports associating the
    pediatric use of Paxil with suicidality, in which it stated: “There
    is no evidence that Paxil is associated with an increased risk of
    suicidal thinking in adults.” FDA Talk Paper, FDA Statement
    Regarding the Anti-Depressant Paxil for Pediatric Population
    (June 19, 2003), available at
    http://www.fda.gov/bbs/topics/answers/2003/ans01230.html (last
    visited Nov. 8, 2007).
    On October 27, 2003, the FDA issued a Public Health
    Advisory regarding increased suicidality in pediatric users of
    antidepressants. This advisory was limited to pediatric patients;
    a warning for adult patients was not issued. In that advisory, the
    FDA announced that it would continue to research the reports of
    suicidality in pediatric patients treated with antidepressants,
    explaining that “[s]uch reports are very difficult to interpret, in
    the absence of a control group, as these events also occur in
    untreated patients with depression.” FDA, FDA Public Health
    Advisory (Oct. 27, 2003), available at
    16
    As with its approvals of Zoloft, the FDA approved Paxil
    for new indications on the condition that the final drug labeling be
    identical to the labeling approved by the FDA. See, e.g., Letter

    January 8, 2008).
    Thus, even when it began to reevaluate its position
    regarding the association of antidepressants with pediatric and
    adolescent suicidality, the FDA continued to announce its
    rejection of adult suicidality warnings for SSRIs as it had for the
    decade before the prescriptions and deaths at issue in this
    litigation. Just months prior to Lois Colacicco’s death, the FDA
    publicly stated that Paxil was not associated with a risk of
    suicidality in adults. Similarly, four months before DeAngelis’
    death, the FDA filed a public brief stating its position that
    scientific evidence did not support the addition of a suicide
    warning on Zoloft’s labeling.
    Although preemption is commonly thought of in terms of
    statutes and regulations, a federal agency’s action taken pursuant
    to statutorily granted authority may also have preemptive effect
    over state law. See Chicago & N. W. Transp. Co. v. Kalo Brick
    & Tile Co., 
    450 U.S. 311
    , 327 (1981) (“These findings by the
    [Interstate Commerce] Commission, made pursuant to the
    authority delegated by Congress, simply leave no room for
    further litigation over the matters respondent seeks to raise in
    state court.”); NCNB Texas Nat’l Bank v. Cowden, 
    895 F.2d 1488
    , 1497-99 (5th Cir. 1990) (finding that Federal Deposit
    Insurance Corporation’s action taken pursuant to statutory
    authority preempted state law); cf. 
    Sprietsma, 537 U.S. at 66-67
    (recognizing that an agency’s refusal to regulate may be
    construed as a determination that no such regulation is
    appropriate and have preemptive force). Because the standard
    for adding a warning to drug labeling is the existence of
    “reasonable evidence of an association of a serious hazard with a
    drug,” 21 C.F.R. § 201.57(e), and the FDCA authorizes the FDA
    to prohibit false or misleading labeling, a state-law obligation to
    include a warning asserting the existence of an association
    between SSRIs and suicidality directly conflicts with the FDA’s
    oft-repeated conclusion that the evidence did not support such an
    association. Therefore, under the circumstances of this case, the
    plaintiffs’ failure-to-warn claims are preempted by the FDA’s
    actions taken in accordance with its statutory authority.
    32
    The FDA clearly and publicly stated its position prior to
    the prescriptions and deaths at issue here. Therefore, we need
    not decide whether preemption would be appropriate under
    different facts--such as where the FDA had not rejected the
    substance of the warning sought or where the FDA only stated
    its position after a lawsuit had been initiated--or under the
    broader theories of preemption argued by the parties. Thus, we
    do not decide whether the FDA’s mere approval of drug labeling
    is sufficient to preempt state-law claims alleging that the
    labeling failed to warn of a given danger, whether FDA approval
    of drug labeling constitutes minimum standards in the absence of
    the FDA’s express rejection of a specific warning, or whether
    actions against generic drug manufacturers are preempted on the
    basis of their obligations under the Hatch-Waxman
    Amendments.17 Our holding is limited to circumstances in
    which the FDA has publicly rejected the need for a warning that
    plaintiffs argue state law requires. Cf. Dowhal v. Smithkline
    Beecham Consumer Healthcare, 
    88 P.3d 1
    , 11 (Cal. 2004)
    (concluding that an FDA “letter established a federal policy
    prohibiting defendants from giving consumers any warning other
    than the one approved by the FDA in that letter, and that the use
    of a [warning required by state law] would conflict with that
    policy”).
    17
    In contrast to our decision, the Supreme Court of Vermont
    has held that plaintiffs’ negligence and failure-to-warn claims
    alleging inadequate warnings on the labeling of an anti-nausea drug
    “did not conflict with the FDA’s labeling requirements for [the
    drug] because [Wyeth] could have warned against [the danger
    alleged by plaintiffs] without prior FDA approval, and because
    federal labeling regulations create a floor, not a ceiling, for state
    regulation.” Levine v. Wyeth, --- A.2d ----, 
    2006 WL 3041078
    , ¶
    6 (Vt. 2006), cert. granted, 
    128 S. Ct. 1118
    (2008). The Vermont
    Court found that there was “no evidence that the FDA intended to
    prohibit defendant from strengthening the [drug] label pursuant to
    [§] 314.70(c)” and thus it was not impossible for Wyeth to comply
    with both state and federal obligations. 
    Id. ¶ 23.
    The facts in these
    cases are otherwise.
    33
    The plaintiffs raise two primary objections to this
    conclusion. First, they argue that nothing less than the FDA’s
    explicit rejection of a drug manufacturer’s request to add a
    contested warning to its drug labeling should suffice to establish
    conflict preemption. Second, they contend that the
    pharmaceutical companies failed to provide the FDA with
    sufficient information for it to make a valid decision regarding
    the necessity of a suicidality warning. Neither argument is
    persuasive.
    As we previously noted, the FDA is authorized by statute
    to reject an NDA if the labeling is false or misleading in any
    particular and may withdraw its approval of a drug upon the
    same findings. See 21 U.S.C. § 355(d)(7), (e)(3). Plaintiffs
    argue, however, that the FDA’s actions were insufficient to
    manifest such a rejection here. They ask us to overlook the
    FDA’s various public statements rejecting the existence of an
    association between SSRIs and adult suicidality because they
    were not made in the context of the FDA’s formal rejection of a
    CBE supplement submitted by one of the defendant
    pharmaceutical companies.
    We agree that a court could more easily determine the
    preemption issue if the FDA had formally rejected such a CBE
    supplement, but we cannot compel the defendant companies to
    suggest a CBE supplement that they believe is unnecessary. Nor
    do we favor encouraging regulated parties to submit CBE
    supplements for the sole purpose of insulating themselves from
    potential liability. Cf. 44 Fed. Reg. 37,434, 37,435 (June 26,
    1979) (cautioning, in the context of medical malpractice liability,
    that “it would be inappropriate to require statements in drug
    labeling that do not contribute to the safe and effective use of the
    drug, but instead are intended solely to influence civil litigation
    in which the agency has no part”). Thus, we reject the notion
    that, in order to rise to the level of a conflict in this situation, the
    FDA’s rejection of a warning must be imbued with the formality
    proposed by the plaintiffs.
    Colacicco further argues that the FDA’s failure to require
    an adult suicidality warning cannot be seen as a rejection of the
    34
    warning that his lawsuit would require because “GSK
    manipulated or withheld information from the FDA.” Colacicco
    Reply Br. at 9. This contention borders on the charge that GSK
    defrauded the FDA by manipulating or withholding such
    information. Cf. 
    Buckman, 531 U.S. at 346-47
    . Such a claim, if
    supported by sufficient evidence, should be brought before the
    FDA. As far as we know from the record, Colacicco has not
    done so.
    In the New Jersey action, McNellis opposed Pfizer’s
    motion for summary judgment by submitting copies of research
    studies that were made public, which McNellis argued showed a
    link between SSRIs and suicidality. McNellis does not argue
    that the FDA was unaware of this material. Our focus is on the
    period before the two deaths that are the subject of the actions
    before us. We note, however, that the FDA has continued its
    close scrutiny of the effect of SSRI drugs on suicidality of
    adults. In March of 2004, the FDA directed GSK and nine other
    manufacturers of SSRIs to include stronger warnings on drug
    labels about the need to monitor adult patients for signs of
    worsening depression or suicidality, but noted that it had “not
    concluded that these drugs cause worsening depression or
    suicidality in adult patients.” 18 Br. for the United States as

    In April 2006, GSK, after reviewing studies that disclosed
    a higher incidence of suicidal behavior in young adults treated with
    Paxil, modified its Paxil label to include a warning that young
    adults “especially those with [major depressive disorder], may be
    at an increased risk of suicidal behavior when treated with” Paxil.

    More recently, the FDA, after its review of the aggregated
    data from all SSRI manufacturers, reaffirmed its conclusion that
    there is insufficient evidence demonstrating that SSRIs are
    associated with adult suicidality. In its widely distributed notice

    “[s]hort-term studies did not show an increase in the risk of
    suicidality with antidepressants compared to placebo in adults
    beyond age 24” and that adults ages 65 and older taking
    antidepressants have a decreased risk of suicidality. Revisions to

    (May 2, 2007).19 The FDA Revisions to Product Labeling
    directed the drug companies (including manufacturers of Paxil
    and Zoloft) to make changes in the warnings included at the
    beginning of the package inserts that confirm that
    antidepressants increase the risk of suicidality in children,
    adolescents, and young adults but that the studies did not show
    an increase in the risk of suicidality in adults older than age 24.20

    We may, of course, take judicial notice of this
    development “which [took] place after the judgment appealed
    from.” Werner v. Werner, 
    267 F.3d 288
    , 295 (3d Cir. 2001).

    The entire text of the revised warning reads as follows:
    Antidepressants increased the risk compared to placebo of
    suicidal thinking and behavior (suicidality) in children,
    adolescents, and young adults in short-term studies of major
    depressive disorder (MDD) and other psychiatric disorders.
    Anyone considering the use of [Insert established name] or
    any other antidepressant in a child, adolescent, or young
    adult must balance this risk with the clinical need. Short-
    36
    In light of the FDA’s continued review of existing scientific
    studies, we reject plaintiffs’ arguments that the FDA lacked
    information that would have dissuaded it from rejecting an adult
    suicidality warning for Zoloft, Paxil, or generic paroxetine in
    2003.
    The FDA has taken the position, both in the preamble to
    the 2006 amendments revising the drug labeling regulations and
    in its amicus brief in the Colacicco case, that plaintiffs’ claims
    are preempted as a result of the actions taken by the FDA
    pursuant to its regulatory authority. The preamble specifically
    states that preemption applies to “claims that a [manufacturer]
    term studies did not show an increase in the risk of
    suicidality with antidepressants compared to placebo in
    adults beyond age 24; there was a reduction in risk with
    antidepressants compared to placebo in adults aged 65 and
    older. Depression and certain other psychiatric disorders are
    themselves associated with increases in the risk of suicide.
    Patients of all ages who are started on antidepressant
    therapy should be monitored appropriately and observed
    closely for clinical worsening, suicidality, or unusual
    changes in behavior. Families and caregivers should be
    advised of the need for close observation and
    communication with the prescriber. [Insert Drug Name] is

    breached an obligation to warn by failing to include a statement
    in labeling or in advertising, the substance of which had been
    proposed to FDA for inclusion in labeling, if that statement was
    not required by FDA at the time plaintiff claims the
    [manufacturer] had an obligation to warn.” 71 Fed. Reg. 3922,
    3936 (Jan. 24, 2006). The FDA explains in the amicus brief that
    “the basis for federal preemption is not the [labeling] guidelines
    themselves . . ., but rather FDA’s repeated determinations prior
    to October 2003 that there was insufficient scientific evidence of
    an association between adult use of SSRI and suicide or
    suicidality to permit a warning on the labeling for those drugs . .
    . .” Br. for the United States as Amicus Curiae at 28.
    We would ordinarily be leery of an agency’s view of what
    is essentially a legal issue, but we note that in Geier the Supreme
    Court recently addressed the weight to be given to an agency’s
    position on preemption. The Court “place[d] some weight” on a
    Department of Transportation interpretation, as set forth in an
    amicus brief, of a rule that it had promulgated. 
    Geier, 529 U.S. at 883
    . The Court considered that Congress had delegated the
    agency “authority to implement the statute; the subject matter is
    technical; and the relevant history and background are complex
    and extensive.” 
    Id. The Court
    stated that the agency was
    “‘uniquely qualified’ to comprehend the likely impact of state
    requirements.” 
    Id. (quoting Lohr,
    518 U.S. at 496). The Court
    also noted the consistency of the agency’s position over time, 
    id., and the
    coherence of the agency’s views, 
    id. at 885.
    Although
    the Court did not rely solely on the agency’s position, it noted
    that “a specific expression of agency intent to pre-empt, made
    after notice-and-comment rulemaking” was not necessary to find
    conflict preemption. 
    Id. From Geier’s
    discussion of an agency’s informal position
    regarding preemption, we conclude (1) that an agency’s position
    concerning preemption need not be contained in a formal
    regulation in order to be considered, and (2) that such a position
    is subject to a level of deference approximating that set forth in
    Skidmore v. Swift & Co., 
    323 U.S. 134
    (1944). Cf. Christensen
    v. Harris County, 
    529 U.S. 576
    , 587 (2000) (quoting 
    Skidmore, 323 U.S. at 140
    ) (holding that agency interpretations contained
    38
    in statements that “lack the force of law” are “‘entitled to
    respect’” only to the extent they have the “‘power to
    persuade’”).21
    “The fair measure of deference to an agency
    administering its own statute has been understood to vary with
    circumstances, and courts have looked to the degree of the
    agency’s care, its consistency, formality, and relative expertness,
    and to the persuasiveness of the agency’s position.” United
    States v. Mead Corp., 
    533 U.S. 218
    , 228 (2001) (alterations
    omitted) (citing 
    Skidmore, 323 U.S. at 139-40
    ).
    It is important to consider the rationale given by the
    agency for its position that its actions preempt state law in the
    particular situation. In the case of the SSRI drugs at issue, Paxil,
    Zoloft, and the generic paroxetine manufactured by Apotex, the
    FDA has explained that “[u]nder-use of a drug based on
    dissemination of unsubstantiated warnings may deprive patients
    of efficacious and possibly lifesaving treatment. Further,
    allowing unsubstantiated warnings would likely reduce the
    impact of valid warnings by creating an unnecessary distraction
    and making even valid warnings less credible.” Br. for the
    United States as Amicus Curiae at 16-17. The FDA’s view that
    “the imposition of liability under state law for defendants’
    alleged failure to warn would interfere with FDA’s
    accomplishment of regulatory objectives,” 
    id. at 22,
    is in our
    21
    Counsel for GSK suggested that a combination of
    Skidmore and Auer deference was appropriate. Under Auer v.
    Robbins, 
    519 U.S. 452
    , 461 (1997) (citations and internal quotation
    marks omitted), an agency’s interpretation of its own regulation is
    “controlling unless plainly erroneous or inconsistent with the
    regulation.” However, because the FDA purports to interpret both
    the statutory structure and regulatory framework, we believe it
    more prudent to apply Skidmore deference, which is the weaker of
    the two. This is also consistent with Geier, wherein the Court
    considered an agency’s interpretation of its own regulation under
    a less deferential standard than that suggested by 
    Auer. 529 U.S. at 883
    .
    39
    view entitled to at least as much deference, if not more, as the
    FDA’s view of its preemption authority. The Pennsylvania
    District Court accorded the FDA’s views “significant”
    deference, 
    Colaciccio, 432 U.S. at 529
    , and we agree that in at
    least this respect the FDA’s view is entitled to some degree of
    deference.
    In light of the circumstances in this case, we agree that
    the FDA’s rejection of the warning plaintiffs proffer preempts a
    state-law action premising liability on a drug manufacturer’s
    failure to include such a warning in the drug labeling
    notwithstanding that the agency’s view was not subject to notice-
    and-comment rulemaking.
    The Supreme Court has recently acknowledged the
    FDA’s expertise in the context of the medical devices covered
    by the MDA. It stated, “[b]ecause the FDA is the federal agency
    to which Congress has delegated its authority to implement the
    provisions of the Act, the agency is uniquely qualified to
    determine whether a particular form of state law ‘stands as an
    obstacle to the accomplishment and execution of the full
    purposes and objectives of Congress,’ and, therefore, whether it
    should be pre-empted.” 
    Lohr, 518 U.S. at 496
    (citing 
    Hines, 312 U.S. at 67
    ). Justice Breyer, concurring in that decision, also
    noted that the Court has “suggested that, in the absence of a clear
    congressional command as to pre-emption, courts may infer that
    the relevant administrative agency possesses a degree of leeway
    to determine which rules, regulations, or other administrative
    actions will have pre-emptive effect.” 
    Id. at 505
    (Breyer, J.,
    concurring) (emphasis added) (citing cases). Of course, the
    FDA is equally expert, if not more so, with respect to regulation
    of drugs, with which it has had a longer experience than with
    medical devices.
    We need not decide whether the FDA’s position in this
    case is inconsistent, as plaintiffs argue, with the FDA’s 2000
    rule proposal. We see no inconsistency between the FDA’s
    preamble to the 2006 amendments and its long-held position that
    it has the responsibility to determine whether a warning is
    required. Compare 44 Fed. Reg. at 37,447 (stating, in 1979, that
    40
    “the decision as to whether a warning is legally required for the
    labeling of a drug must rest with the agency”), with 71 Fed. Reg.
    at 3934 (“In fact, the determination whether labeling revisions
    are necessary is, in the end, squarely and solely FDA’s under the
    act.”).
    In conclusion, based on our own review of the FDCA, the
    FDA’s regulations, and the FDA’s actions taken pursuant to its
    statutory authority, we conclude that the failure-to-warn claims
    brought by Colacicco and McNellis conflict with, and are
    therefore preempted by, the FDA’s regulatory actions. It is
    important to note that we express no view as to the merits of the
    issue whether SSRIs contribute to adult suicidality. We are not
    scientists and we do not purport to have any expertise on that
    issue. That is within the FDA’s authority. This decision is
    based on the record before us.
    V.
    For the above-stated reasons, we will affirm the judgment
    of the United States District Court for the Eastern District of
    Pennsylvania dismissing Colacicco’s complaint and we will
    reverse the order certified by the United States District Court for
    the District of New Jersey with instructions that judgment be
    entered in favor of the defendants. In light of our decision with
    respect to preemption, we need not reach the other issues
    considered by the District Courts.

    Colacicco v. Apotex Inc., et al. McNellis v. Pfizer Inc.
    Nos. 06-3107/5148
    AMBRO, Circuit Judge, dissenting
    The majority opinion describes these cases as situations
    calling for preemption: the expert agency, the Food and Drug
    Administration (“FDA”), consults scientific data to generate the
    optimal warnings (not too lax, not too alarmist) for drug
    labels—and state tort lawsuits would disrupt this fine system.
    But there is an important contrary view that has prevailed until
    recently: state tort law complements FDA provisions on drug
    warnings, in part by eliciting more information than the FDA
    would glean otherwise from pharmaceutical manufacturers. This
    contrary view has, I believe, the better argument in terms of legal
    doctrine on preemption, congressional intent, and the history of
    state tort law alongside federal law. Although the majority
    opinion is well-crafted and responsibly narrow, I would not
    move even the short distance my colleagues go toward
    preemption of state-law torts. I thus respectfully dissent.
    I. Presumption Against Preemption
    The majority opinion begins its analysis where I would,
    by examining whether we are to apply a presumption against
    preemption. State tort law, dealing with failure-to-warn claims
    (like those brought by the plaintiffs in our cases), addresses
    health and safety and thus falls within the states’ traditional
    police powers. See Medtronic, Inc. v. Lohr, 
    518 U.S. 470
    , 485
    (1996) (describing the presumption against preemption and
    asserting “the historic primacy of state regulation of matters of
    health and safety”). As the majority recognizes, the presumption
    does not always apply; for example, it does not apply to claims
    alleging fraud on the FDA. See Buckman Co. v. Plaintiffs’ Legal
    Comm., 
    531 U.S. 341
    , 347–48 (2001). That the presumption
    there does not apply—where common sense points to federal law
    42
    governing exclusively those who seek to defraud a federal
    agency—is no surprise, and hardly weakens the presumption
    when it does apply.
    The presumption against preemption must inform our
    analysis of both “whether Congress intended any pre-emption at
    all” and “the scope of its intended invalidation of state law.”
    
    Lohr, 518 U.S. at 485
    (emphasis omitted). When the
    presumption applies, rebutting it requires a clear expression that
    Congress intended to preempt. Bates v. Dow Agrosciences LLC,
    
    544 U.S. 431
    , 449 (2005) (“In areas of traditional state
    regulation, we assume that a federal statute has not supplanted
    state law unless Congress has made such an intention clear and
    manifest.”) (citations and internal quotation marks omitted).
    In my view, the majority opinion under-emphasizes
    congressional intent as the “ultimate touchstone of pre-emption
    analysis.” Cipollone v. Liggett Group, Inc., 
    505 U.S. 504
    , 516
    (1992) (citations and internal quotations marks omitted). Our
    inquiry is “guided” by a focus on gaining “ ‘a fair understanding
    of congressional purpose.’ ” 
    Lohr, 518 U.S. at 485
    –86 (quoting
    
    Cipollone, 505 U.S. at 530
    ) (emphasis in original). As the
    majority opinion rightly recognizes, the defendants in our cases
    do not make a serious argument that this case involves express
    preemption or field preemption. But I would place more
    significance on the fact that the key conflict preemption cases
    that the majority opinion relies on involve express statutory
    preemption provisions. Geier v. American Honda Motor
    Company, 
    529 U.S. 861
    , 864–65 (2000) (evaluating viability of
    state-tort-law claims in light of a preemption provision, 15
    U.S.C. § 1392(d), and a savings provision, 
    id. § 1397(k),
    within
    the National Traffic and Motor Vehicle Safety Act of 1966);
    
    Lohr, 518 U.S. at 481
    (evaluating viability of state-tort-law
    claims in light of the preemption provision of the Medical
    Devices Act, 21 U.S.C. § 360k(a)).
    43
    Even when considering a species of implied
    preemption—as conflict preemption generally is, see 
    Geier, 529 U.S. at 884
    —we should be asking whether Congress intended to
    preempt. In our cases, we have no statutory preemption
    provision to interpret that relates to drug labeling in the Food,
    Drug and Cosmetic Act (“FDCA”). This fact should push us to
    hold the presumption against preemption in place, as we lack the
    best kind of evidence of congressional intent: statutory text.
    The absence of a relevant preemption provision in the
    FDCA does not, of course, resolve whether the presumption
    against preemption is overcome by something else. The
    Supreme Court has “held repeatedly that state laws can be
    pre-empted by federal regulations as well as by federal statutes.”
    Hillsborough County v. Automated Med. Labs., 
    471 U.S. 707
    ,
    713 (1985). Although initial approval of drug labeling involves
    both statutory and regulatory provisions, FDA regulations
    primarily govern the continuing oversight of drug-label
    revisions. These regulations, at the time relevant to this
    litigation, required drug manufacturers to revise labeling “to
    include a warning as soon as there is reasonable evidence of an
    assocation of a serious hazard with a drug,” 21 C.F.R. §
    201.57(e), and to submit supplemental information in the event
    that they “add or strengthen a contraindication, warning,
    precaution, or adverse reaction,” 
    id. § 314.70(c).
    The defendants
    in our cases rely primarily on their continuing obligations under
    these FDA regulations for their conflict-preemption argument.
    Yet the mere presence of a comprehensive regulatory
    scheme such as the FDA’s for drug labeling does not itself
    unseat the presumption against preemption. Hillsborough
    
    County, 471 U.S. at 717
    (“We are even more reluctant to infer
    pre-emption from the comprehensiveness of regulations than
    44
    from the comprehensiveness of statutes.”).22 Because our focus
    must remain on congressional intent, we should remember in
    deciding questions of regulatory preemption that any inferences
    regarding congressional purpose typically will be indirect.
    Congress enacted the FDCA, which in turn enabled the FDA to
    adopt its regulations regarding continuing (i.e., post-approval)
    drug labeling. To overcome the presumption against
    preemption, the defendants in our cases must show that Congress
    implicitly intended to allow the FDA to adopt regulations that
    preempt failure-to-warn lawsuits under state law. Cf. Fidelity
    Federal Sav. & Loan Ass’n v. de la Cuesta, 
    458 U.S. 141
    , 162
    (1982) (holding that Federal Home Loan Bank Board regulations
    preempted state law where “the statutory language suggests that
    Congress expressly contemplated, and approved, the Board’s
    promulgation of regulations superseding state law” after also
    inquiring into the Board’s own intent to preempt).
    The majority opinion closes its discussion of the
    presumption against preemption by describing a “tension”
    between the presumption as outlined in Lohr and some
    seemingly contrary language in Geier. But the Geier side of this
    doctrinal tug-of-war has slippery footing. The quoted
    language—“[O]ne can assume that Congress or an agency
    ordinarily would not intend to permit a significant conflict,”
    22
    The majority opinion suggests that, because Hillsborough
    County considered field preemption in analyzing the municipal
    ordinances at issue, the operation of the Supreme Court’s
    application of the presumption against preemption in that case “is
    not clear.” I disagree with this suggestion. Hillsborough County’s
    discussion of the presumption against preemption appears in Part
    III of that 
    opinion. 471 U.S. at 714
    –16. The field-preemption
    analysis in Sections IV.A and IV.B, and the conflict-preemption
    analysis in Section IV.C, follow. 
    Id. at 716–20.
    In my view, the
    Court’s purpose in setting out the presumption against preemption
    in Part III was to indicate that the presumption should guide the
    analysis in all sections of Part IV.
    45
    
    Geier, 529 U.S. at 885
    —appears as a dictum in the context of a
    larger discussion of whether an agency must adopt a clear
    statement of preemptive intent for a conflict between federal
    regulation and state law to exist.23 This sentence does not create
    a counter-presumption in favor of preemption, for the very next
    sentence in Geier states that “a court should not find pre-emption
    too readily in the absence of clear evidence of a conflict.” 
    Id. That is
    a restatement of the presumption against preemption,
    suggesting that we should not interpret Geier to muddy the
    presumption or to dilute its effect.24
    When a federal court undertakes a conflict-preemption
    analysis, a “significant conflict” between federal and state law
    might be the kind of “clear evidence” that could rebut the
    presumption against preemption. 
    Geier, 529 U.S. at 885
    . We
    can assume Congress or the FDA had awareness of products-
    liability law when legislating or regulating. So if we find a
    genuine conflict, we may conclude that Congress intended to
    preempt state law. But in situations involving less obvious
    conflicts, the presumption against preemption will be more
    difficult to overcome.
    I would apply the presumption against preemption here.
    23
    That discussion in Geier settles the issue: an agency need
    not do so for a conflict to 
    exist. 529 U.S. at 884
    –85. Even without
    express statutory preemption or a clear agency statement on
    preemption, a court may find that state law “actual[ly] conflict[s]”
    with federal law under the facts of a particular case. 
    Id. at 884
    (quoting English v. Gen. Elec. Co., 
    496 U.S. 72
    , 79 (1990)). I
    address the broader issue of how much deference we owe an
    agency’s position on preemption below. See infra Part II.
    24
    In contrast, the majority opinion never again mentions the
    presumption against preemption after Section IV.A of its opinion,
    suggesting that the presumption is performing virtually no
    analytical work.
    46
    The plaintiffs’ failure-to-warn claims stand near the heart of the
    states’ police powers over matters of health and safety. And the
    existence and detailed nature of the federal scheme does not
    change our imperative to require clear congressional intent
    (whether expressed directly in a preemption provision or implied
    by an authorizing statute enabling an agency to act) to preempt
    state tort law.
    II. Deference to the FDA’s View on Preemption
    At the end of its conflict-preemption analysis—even after
    addressing the plaintiffs’ arguments—the majority opinion
    considers the FDA’s own view regarding the preemptive effect
    of its drug-labeling regulations. In 2006, the preamble to an
    FDA revision of its drug-labeling regulations stated that failure-
    to-warn claims are preempted if, at the time of injury, the
    substance of the alternative warning proposed by plaintiffs (1)
    had already been submitted to the FDA and (2) had not been
    adopted. 71 Fed. Reg. 3922, 3936 (Jan. 24, 2006). The FDA
    also filed an amicus brief in the Colacicco case before us,
    arguing that “federal law preempts a state tort claim arising out
    of drug manufacturers’ alleged failure to provide a warning that
    FDA determined was not scientifically supported.” FDA Br. 16.
    The FDA emphasizes that it strives for the optimal strength of
    warning. Anything less or more than the FDA-approved and
    FDA-monitored warning, in the agency’s view, would be “false
    or misleading.” See 21 U.S.C. §§ 331(a)–(b), 352(a); Br. of
    Amicus Curiae United States at 2.
    We must decide what weight we should give to these
    FDA views before analyzing the purported conflict in this case.
    I agree with the majority opinion that we should apply Skidmore
    deference to the FDA’s informal position contained in its 2006
    preamble and its amicus brief in Colacicco. See 
    Geier, 529 U.S. at 883
    (placing “some weight” on the Department of
    Transportation’s interpretation of its own airbag regulation);
    47
    Skidmore v. Swift & Co., 
    323 U.S. 134
    , 139 (1944) (giving the
    Department of Labor’s “interpretive bulletin” regarding the
    calculation of working hours a level of deference based on “all
    those factors which give it power to persuade, if lacking power
    to control”). The formulation in Mead, which cites Skidmore
    and which the majority opinion quotes, designates the following
    factors for consideration: “the degree of the agency’s care, its
    consistency, formality, and relative expertness, and to the
    persuasiveness of the agency’s position.” United States v. Mead
    Corp., 
    533 U.S. 218
    , 228 (2001).
    I disagree with the majority opinion, however, in its
    application of the standards articulated in Skidmore and Mead.
    Comparing FDA statements from 1979 and 2006, my colleagues
    discern “no inconsistency” between them.25 I suggest a better
    analysis of inconsistency would take a more detailed view of the
    FDA’s position(s) during the 27 intervening years.26 For
    25
    Importantly, the majority opinion’s quote from the 1979
    regulation is taken out of context. Rather than contemplating the
    FDA’s relation to state courts, the quoted sentence discusses the
    FDA’s relation to panels of experts from which the agency seeks
    advice: “Although FDA often refers questions of whether a
    warning should be included in the labeling of a drug to its standing
    advisory committees, the decision as to whether a warning is
    legally required for the labeling of a drug must rest with the
    agency.” 44 Fed. Reg. 37,434, 37,447 (June 26, 1979) (emphasis
    added). Thus there is no support I can find in the record for the
    proposition that, in 1979, the FDA viewed its drug-labeling
    regulations as preemptive of state tort law.
    26
    Some Supreme Court cases suggest that inconsistency is
    no bar to deference. See, e.g., Motor Vehicle Mfrs. Ass’n v. State
    Farm Mut. Auto Ins. Co., 
    463 U.S. 29
    . 42 (1983). But others have
    language suggesting that inconsistency counts against the agency’s
    position. See, e.g., 
    Bates, 544 U.S. at 449
    (finding a preemption
    argument “particularly dubious” in light of the EPA’s change in
    position within five years).
    48
    instance, only slightly more than seven years ago the FDA
    disavowed any “federalism implications” or preemptive effect of
    changes to its requirements for prescription drug labeling. 65
    Fed. Reg. 81,082, 81,103 (Dec. 22, 2000). Rather than
    maintaining a consistent position, the FDA now undertakes a
    “180-degree reversal.” David A. Kessler & David C. Vladeck, A
    Critical Examination of the FDA's Efforts to Preempt
    Failure-to-Warn Claims, 96 Geo. L.J. 461, 474 n.59 (2008)
    (internal quotation marks omitted). Its current position is novel
    rather than longstanding. See 
    id. at 462
    (“For most of its
    seventy-seven-year history [since receiving the name “Food and
    Drug Administration” in 1930], the [FDA] has regulated the
    drugs sold in the United States without any significant
    interaction with the world of state-law damages litigation.”). I
    thus conclude that the FDA’s position regarding preemption
    deserves little deference by way of its inconsistency.
    The majority opinion relies on another of the Skidmore
    and Mead factors: agency expertise. Undoubtedly, the FDA has
    special expertise in evaluating the scientific evidence on
    pharmaceuticals’ safety and efficacy. That expertise should
    contribute to any consideration of the proper mix of legal
    institutions used to regulate drug labeling. But, as my colleagues
    note, “[w]e would ordinarily be leery of an agency’s view of
    what is essentially a legal issue.” The FDA is not an expert on
    federalism concerns. Nor is the agency the only Government
    institution that should bring its perspective to bear on the
    relationship between the executive branch and state courts;
    Congress, federal courts, and state courts each have a
    constitutional responsibility under the Supremacy Clause to
    evaluate such issues. Thus, I would consider the FDA’s
    expertise only a mild positive in our calculation of how much
    deference to apply in these cases.
    The remaining factors listed in Mead weigh against
    giving the FDA’s view on preemption much deference. With
    49
    respect to “formality,” the FDA has not engaged in notice-and-
    comment rulemaking on this issue, instead promulgating its
    views in a preamble to a regulation and a series of amicus briefs
    in cases like these. As the majority notes, notice-and-comment
    rulemaking is not required to find conflict preemption. See
    
    Geier, 529 U.S. at 885
    . But the lack of notice-and-comment
    rulemaking should, all else equal, reduce the level of deference
    we give the FDA’s position. Similarly, the lack of institutional
    formality suggests a relatively low “degree of care” taken to
    outline its reasoning.27 In my view, a high degree of care on
    issues of preemption would involve scholarly, scientific, and
    public-health 28 research into the complex matters of law and
    policy that these cases implicate. I see no evidence in the record
    that the FDA conducted or commissioned independent research
    of this nature in preparing the 2006 preamble.
    In summary, the Mead factors counsel us to give the
    FDA’s position a relatively low level of deference. The ultimate
    test under Skidmore is nonetheless whether the FDA’s (and the
    defendants’) view has the “power to 
    persuade,” 323 U.S. at 139
    ,
    27
    By making this point I do not mean to criticize FDA
    counsel’s efforts in writing its amicus brief in this case or at oral
    argument. On the contrary, counsel performed admirably in both
    regards. My focus here is in-depth institutional research on law
    and policy preceding the recent “about face” on agency
    preemption.
    28
    A group of public health researchers writes that “[i]ndirect
    regulation of the pharmaceutical industry by tort litigation is an
    important complement to the regulation of drug safety by the
    FDA.” Br. of Amicus Curiae Curt D. Furberg, M.D., Ph.D., et al.
    at 6. This view—based on various scholarly, peer-reviewed
    articles—does not receive any attention in the 2006 preamble or in
    the FDA’s amicus brief. Notice-and-comment rulemaking would
    provide a forum for such research to be considered, but, as noted,
    the FDA has not undertaken that administrative process on the
    issue of preemption of state tort law.
    50
    an evaluation I take up in Part III.
    III. Conflict Preemption.
    The defendants’ argument is that labeling that satisfies
    the FDA is both the minimum and the maximum amount of
    labeling they may do. Under this view, the FDA believes it has
    struck the proper balance between safety and efficacy, that is,
    between avoiding unintended injuries to patients because of
    insufficient warnings while not deterring too many patients from
    using drugs that would benefit them because of unjustified over-
    warnings. Adding additional warnings unsupported by medical
    evidence would subject the defendants to FDA sanctions for
    false labeling. Conflict preemption must apply to block state-
    law claims for failure to warn, according to the defendants, since
    stronger warnings for Paxil and Zoloft—the drugs within the
    category of selective seratonin reuptake inhibitors (“SSRIs”)
    involved in these cases—would violate FDA regulations. This
    makes it impossible, defendants continue, for them to have
    complied with both state and federal law. Alternatively,
    imposing an overlay of tort liability would frustrate the federal
    objective of having the FDA strike the safety-efficacy balance.
    For the reasons I describe below, I disagree with this
    characterization of the interaction of FDA regulation and state
    tort law. Informed by the presumption against preemption, I see
    the federal and state constructs as complementary, as they have
    been since the 1930s. The majority opinion’s holding of
    preemption in these cases, despite an apparently narrow
    construction, threatens the institutional framework we have for
    balancing safety and efficacy in the pharmaceutical industry
    while compensating victims of wrongful injuries.
    A. Absence of an Actual Conflict
    51
    None of the drug manufacturers in these cases attempted
    to enhance a warning and received an FDA sanction in response.
    The majority opinion correctly states that hypothetical conflicts
    can give rise to conflict preemption. But the hypothetical in
    question must be convincing for us to allow this. The conflict
    the defendants raise relies, at its heart, on the FDA punishing
    drug manufacturers for over-warning. But a heightened warning
    would likely have its source in new information that the FDA
    had not previously known. Thus, I find it hard to believe that, if
    a drug manufacturer augmented its warning in response to or in
    anticipation of a state tort lawsuit, the FDA would sanction the
    manufacturer for over-warning consumers under 21 U.S.C.
    §§ 331(a)–(b) and 352(a).
    Indeed, drug manufacturers have authority to strengthen
    warnings without advance permission from the FDA. The plain
    language of 21 C.F.R. § 314.70 permits unilateral additions to
    warnings, subject to subsequent FDA approval: “[T]he holder of
    an approved application may commence distribution of the drug
    product involved upon receipt by the agency of a supplement for
    the change,” including such changes as “add[ing] or
    strengthen[ing] a contraindication, warning, precaution, or
    adverse reaction.” 21 C.F.R. §§ 314.70(c)(6), (c)(6)(iii)(A). The
    motivation for additional warnings, which the regulation does
    not address, need not come from inside the pharmaceutical
    company in question or FDA prodding. In particular, that
    motivation may come from a failure-to-warn lawsuit or the threat
    of one.
    Drug manufacturers have the best information about the
    safety of their products. The FDA does not conduct its own drug
    trials and “does not have sufficient authority to require
    additional clinical trials after drug approval.” Mary J. Davis,
    The Battle Over Implied Preemption: Products Liability and the
    FDA, 48 B.C. L. Rev. 1089, 1149 (2007). Thus, to avoid
    discouraging the party with the best safety information from
    52
    coming forward, 21 C.F.R. § 314.70 permits a manufacturer to
    alter a drug label before the FDA has evaluated and approved the
    change.
    The defendants and the FDA do not cite even one
    example of the FDA punishing a drug manufacturer for over-
    warning. See Oral Argument Tr. 82, Dec. 10, 2007 (statement of
    FDA counsel that she was “not aware of any instance” in which
    the FDA “told a manufacturer who added an increased warning
    that that warning was unsubstantiated and caused the drug to be
    misbranded”).29 At oral argument, counsel for GlaxoSmithKline
    mentioned that, in 2004, the FDA required additional language
    in response to a strengthened warning by Wyeth Pharmaceuticals
    in a “changes being effected” supplement under 21 C.F.R. §
    314.70. Merely requiring a clarification of or addition to
    warning language does not strike me as close to being close to a
    true conflict. On the contrary, the Wyeth example shows that the
    FDA typically engages in a back-and-forth discussion with drug
    manufacturers about warnings. In the event of a state tort
    lawsuit resulting in a warning that conflicted with the FDA’s
    previous judgment, a commonplace dialogue between the
    manufacturer and the FDA could produce a warning complying
    with both federal regulations and state tort law.
    B. Harmony Between Tort Law and FDA Regulation
    Tort law and FDA regulation do not have conflicting
    29
    The majority opinion emphasizes a different fact: that the
    FDA, in response to citizen petitions and approvals of new uses for
    existing SSRIs, considered requiring a strengthened warning and
    declined. I agree that inaction of this kind is a form of agency
    action. But more important to me is that the FDA may never have
    sanctioned a drug manufacturer that strengthened a warning
    without prior FDA approval. This additional example of FDA
    inaction suggests that the conflict complained of is not an actual
    conflict.
    53
    goals. Both seek to strike a safety–efficacy balance. Under a
    negligence standard, most state courts balance the cost of care
    owed to a patient against the prospective harm. See, e.g., La
    Russa v. Four Points at Sheraton Hotel, 
    821 A.2d 1168
    ,
    1173–74 (N.J. Super. Ct. 2003) (quoting Judge Learned Hand’s
    formula from United States v. Carroll Towing Co., 
    159 F.2d 169
    , 173, reh’g denied, 
    160 F.2d 482
    (2d Cir.1947), which
    compares the cost of precautions with the expected loss);
    cf. Stephen G. Gilles, On Determining Negligence: Hand
    Formula Balancing, The Reasonable Person Standard, and the
    Jury, 54 Vand. L. Rev. 813, 816–22 (2001) (describing
    widespread use of, as well as complications in applying, the
    Hand formula).
    Properly understood, the cost of additional warnings
    includes the consequences of over-warning that the defendants
    emphasize and that the FDA similarly takes into account.30 In
    reaching its holding of conflict preemption, the majority focuses
    on the hypothetical scenario of differing (and presumably
    conflicting) results of the FDA regulatory process and state tort
    lawsuits. Because we are dealing with hypothetical situations,
    however, I would focus on the essential harmony of the
    standards applied by the FDA and state courts rather than the
    disharmony conjured about the results. Both institutions seek to
    balance safety and efficacy. If it turns out those results actually
    conflict, then it is time for Congress to step in or at least for the
    FDA to propose a rule followed by public comment before
    30
    Advocates of preemption in these cases point to the
    danger of “over-warning” and imply that over-warning will result
    from jury decisions biased toward plaintiffs. Br. of Amicus Curiae
    Product Liability Advisory Council, Inc. at 14–23. This argument
    assumes that juries do not understand that the cost of care,
    including the cost of taking too much care, is part of determining
    negligence. I presume, for the purposes of analyzing a hypothetical
    conflict between federal and state law, that state-court judges will
    properly instruct juries about the negligence standard.
    54
    proclaiming preemption.
    Allowing multiple institutions to investigate the difficult
    question of how strong to make a warning can have important
    benefits. State courts provide a check on agency power. Our
    society relies on the FDA to an enormous degree to monitor the
    safety of pharmaceuticals. But the FDA’s toolkit is imperfect
    and incomplete by design. The FDA relies on the information
    provided by drug manufacturers (to repeat, it does no
    independent testing), and will always lack the inside perspective
    on clinical trials and data analyses stemming from those trials.
    Moreover, the FDA is limited as to the additional clinical trials it
    may require post-approval, 
    Davis, supra, at 1149
    & n.444, and
    even “the reporting process for postapproval adverse reaction
    events . . . is too weak,” 
    id. at 1149
    & n.443. Also, as they play
    their parts in the post-approval process the drug manufacturer
    and the FDA will not necessarily ask the right questions. The
    citizen-petition administrative process was used here
    unsuccessfully to seek an FDA requirement of stronger warnings
    for SSRIs. Discovery in state tort lawsuits provides a different
    way for third parties to raise questions about new and existing
    drugs. Given this context, I would not eliminate the potentially
    valuable information-gathering tools of state tort law.
    To make all this real, I would point out that the regulatory
    process at the FDA, even if it allows for submission of citizen
    petitions, does not compensate the families of alleged victims
    like Lois Colacicco and Theodore DeAngelis. The availability
    of damages in state tort lawsuits can give injured citizens the
    incentive to come forward and share potentially valuable
    information. Even if an injury or death turns out not to have
    been caused by a drug or an insufficient warning, that
    information, too, can have social value. And the prospect of
    paying damages can sharpen drug manufacturers’ incentives to
    place appropriate weight on safety as they strike the
    safety–efficacy balance. We should not lightly assume this
    55
    balance now preempted—and by a single recently adopted
    preamble at that.
    C. Backdoor Federalization
    The FDA’s position in these cases is an instance of
    “backdoor federalization,” a descriptive term commentators have
    recently used to describe a trend in the federal courts toward
    finding state law preempted. On the positive side, centralized
    federal control can facilitate uniform regulation of a national
    market (like that for pharmaceuticals) and prevent states from
    interfering with the affairs of other states. Samuel Issacharoff &
    Catherine M. Sharkey, Backdoor Federalization, 53 UCLA L.
    Rev. 1353 (2006).
    Unfortunately, the trend toward federalization is not fully
    benign. While the FDA seeks to keep private plaintiffs out of
    state court (or federal court applying state law in diversity
    actions), a separate line of jurisprudence has limited private
    rights of action. There is a “troublesome” contrast in the way
    courts now tend to “grant agencies expansive discretion to
    interpret or declare the preemptive scope of the regulations they
    promulgate, whereas agencies are not given corresponding
    latitude to infer private rights of action under those same
    regulations.” Catherine M. Sharkey, Preemption by Preamble:
    Federal Agencies and the Federalization of Tort Law, 56 DePaul
    L. Rev. 227, 258–59 (2007).
    Although the FDA should have a strong voice in the
    debate among government institutions about preemption of state
    tort law, by executive order it must consult with state and local
    governments about the consequences of its regulations. See 
    id. at 252–55
    (citing Exec. Order No. 13,132, 64 Fed. Reg. 43,255,
    43,257 (Aug. 10, 1999)). But nothing in the record suggests a
    dialogue between federal and state officials has occurred
    regarding preemption of failure-to-warn lawsuits.
    56
    I would interpret the absence of an express preemption
    statute, the text of the actual FDA regulations, and the late
    arrival of the FDA’s statement on preemption in a preamble, as
    evidence that state tort law is not displaced. Tort lawsuits can
    generate useful information that the FDA can inject into its
    regulatory process. And tort damages can aid the FDA in
    aligning drug manufacturers’ incentives to find the right balance
    between safety and efficacy. In any event, the choice to preempt
    state tort law is best left to Congress, should it wish to do so. In
    these cases, I do not see the kind of conflict that implies
    Congress has made that choice.
    IV. Conclusion
    The plaintiffs allege that SSRIs increase the risk of
    patients committing suicide. They further allege that the drug
    manufacturers knew or should have known this, but failed to
    label their products appropriately. The defendants would have
    us halt any inquiry into their alleged negligence before it starts.
    They contend that, in the area of drug labeling, state tort law
    renders compliance with federal provisions impossible, or at
    least stands as an obstacle to federal objectives.
    The FDA, which relies on information provided by
    others, seeks to stop one avenue of information—that gathered
    from suits under state tort law theories. But should an earlier
    series of FDA decisions indicating that the previous warnings
    were adequate, when they might be inadequate, preclude the
    operation of state tort law? The majority suggests that the
    plaintiffs’ claims border on claiming fraud on the FDA. But the
    underlying issue in these preemption cases is the structure of
    federal–state relations. We must decide whether the FDA will
    be the sole decision-maker. Without a clear statement from
    Congress or clear evidence that state law “stands as an obstacle
    to the accomplishment and execution of the full purposes and
    objectives of Congress,” Hines v. Davidowitz, 
    312 U.S. 52
    , 67
    57
    (1941), I am reluctant to say that the defendants’ claim of a
    conflict has scaled the presumption against preemption.
    A holding of no preemption in these cases would not
    suggest in any way that the defendant drug manufacturers should
    be liable for plaintiffs’ injuries. Like my majority colleagues, I
    express no view regarding the relationship between SSRIs and
    adult suicide. Allowing the plaintiffs’ cases to proceed beyond
    the motion-to-dismiss stage means instead that the state courts
    and federal district courts applying state tort law may
    evaluate—provide a check on—whether the FDA struck the
    right balance in the precautions and warnings it required for
    SSRIs.
    To review the history of this issue, the FDA has for over
    three-quarters of a century viewed state tort law as
    complementary to its warning regulations. Only for the last two
    years has it claimed otherwise. This “sea change,” 
    Sharkey, supra, at 242
    , in the FDA’s conception of the relationship
    between federal and state law has not appeared in a regulation
    subject to notice and comment, but in a preamble to a regulation.
    With this background, I believe courts should fear to tread where
    Congress has not given us a clear statement. Because I see
    sound legal and policy reasons to hold that the presumption
    against preemption is not overcome, I would allow the plaintiffs’
    suits to go forward. I respectfully dissent.
