    PRESENT:     Reiber, C.J., Dooley and Johnson, JJ., and Morris, D.J., and
    Allen, C.J. (Ret.), Specially Assigned
    ¶   1.     JOHNSON, J.  Defendant Wyeth, a drug manufacturer, appeals
    from a jury verdict in favor of plaintiff Diana Levine, who suffered severe
    injury and the amputation of her arm as a result of being injected with
    defendant's drug Phenergan.  Plaintiff claimed at trial that defendant was
    negligent and failed to provide adequate warnings of the known dangers of
    injecting Phenergan directly into a patient's vein.  Defendant argues that
    the trial court should not have allowed the jury to consider plaintiff's
    claims because the claims conflict with defendant's obligations under
    federal law regulating prescription drug labels.  We hold that there is no
    conflict between state and federal law that requires preemption of
    plaintiff's claim.  Defendant also raises two claims of error relating to
    the jury instructions on damages.  We hold that the court's rulings on
    these jury instructions were correct, and we affirm.
    ¶   2.     In April 2000, plaintiff was injected with defendant's drug
    Phenergan at Northeast Washington County Community Health, Inc. ("the
    Health Center").  The drug was administered to treat plaintiff's nausea
    resulting from a migraine headache.  Plaintiff received two injections.
    The drug was first administered by intramuscular injection.  Later the same
    day, when plaintiff's nausea continued, she received a second dose by a
    direct intravenous injection into her arm, using a procedure known as "IV
    push."  The second injection resulted in an inadvertent injection of
    Phenergan into an artery.  As a result, the artery was severely damaged,
    causing gangrene.  After several weeks of deterioration, plaintiff's hand
    and forearm were amputated.
    ¶   3.     Plaintiff brought a superior court action for negligence
    and failure-to-warn product liability, alleging that defendant's inadequate
    warning of the known dangers of direct intravenous injection of Phenergan
    caused her injuries.  During a five-day jury trial, both parties presented
    expert testimony regarding the adequacy of the warnings defendant placed on
    Phenergan's label.  Plaintiff's experts testified that the label should not
    have allowed IV push as a means of administration, as it was safer to use
    other available options, such as intramuscular injection or administration
    through the tubing of a hanging IV bag.  Defendant's expert testified that
    allowing IV push with instructions cautioning against inadvertent arterial
    injection was sufficient.  The court instructed the jurors that they could
    consider the FDA's approval of the label in use at the time of plaintiff's
    injury, but that the label's compliance with FDA requirements did not
    establish the adequacy of the warning or prevent defendant from adding to
    or strengthening the warning on the label.  At the conclusion of the trial,
    the jury found in favor of plaintiff on both the negligence and
    product-liability claims and awarded her $2.4 million in economic damages
    and $5 million in non-economic damages.  Pursuant to the parties'
    stipulation, this award was reduced to a total of $6,774,000 to account for
    pre-judgment interest and plaintiff's recovery in a settlement of a
    separate action she had filed against the Health Center.
    ¶   4.     In a summary judgment motion prior to trial, as well as in
    its timely motion for judgment as a matter of law following trial, both of
    which the superior court denied, defendant argued that federal law
    preempted plaintiff's claim.  These arguments rested in part on defendant's
    contention that it had submitted an adequate warning to the FDA, but that
    the FDA rejected the change because it did not favor strengthening the
    warning.(FN1)  Plaintiff contended that neither warning would have been
    adequate.  The trial court stated, in its decision on defendant's motion
    for judgment as a matter of law, that although the FDA had rejected a new
    warning, the agency's "brief comment" failed to explain its reasoning or
    demonstrate that it "gave more than passing attention to the issue of
    whether to use an IV infusion to administer the drug.  The proposed
    labeling change did not address the use of a free-flowing IV bag."   The
    court concluded that there was "no basis for federal preemption" and upheld
    the jury's verdict.
    ¶   5.     Defendant claims the superior court erred by: (1) failing
    to dismiss plaintiff's claim on the basis that the Food and Drug
    Administration's approval of the Phenergan label preempted state common law
    claims that the label was inadequate; (2) failing to instruct the jury to
    reduce plaintiff's damages by the amount of fault attributable to the
    Health Center; and (3) failing to instruct the jury to calculate the
    present value of plaintiff's damages for future non-economic losses.  We
    reject these claims of error, and we affirm.
    I.     Federal Preemption
    ¶   6.     Defendant's principal argument on appeal is that the court
    should have dismissed plaintiff's claim because it was preempted by federal
    law.  Defendant asserts that any state common law duty to provide a
    stronger warning about the dangers of administering Phenergan by IV push
    conflicts with the FDA's approval of the drug's label.  As preemption is a
    question of law, we review the trial court's decision de novo.  Office of
    Child Support v. Sholan, 
    172 Vt. 619
    , 620, 
    782 A.2d 1199
    , 1202 (2001)
    (mem.).  We hold that the jury's verdict against defendant did not conflict
    with the FDA's labeling requirements for Phenergan because defendant could
    have warned against IV-push administration without prior FDA approval, and
    because federal labeling requirements create a floor, not a ceiling, for
    state regulation.
    ¶   7.     The United States Constitution provides that federal law is
    the supreme law of the land.  U.S. Const. art. VI, cl. 2.  The Supremacy
    Clause is the basis for the doctrine of preemption, according to which
    "state law that conflicts with federal law is 'without effect.' " Cipollone
    v. Liggett Group, Inc., 
    505 U.S. 504
    , 516 (1992) (quoting Maryland v.
    Louisiana, 
    451 U.S. 725
    , 746 (1981)).  In Cipollone, the Court described
    the relevant analysis for determining whether Congress intended a federal
    statute to preempt state law:
    Congress' intent may be explicitly stated in the statute's
    language or implicitly contained in its structure and
    purpose.  In the absence of an express congressional command,
    state law is pre-empted if that law actually conflicts with
    federal law, or if federal law so thoroughly occupies a
    legislative field as to make reasonable the inference that
    Congress left no room for the States to supplement it.
    Id. (quotations and citations omitted).  Absent clear congressional intent
    to supersede state law, including state common law duties, there is a
    presumption against preemption.  Medtronic, Inc. v. Lohr, 
    518 U.S. 470
    , 485
    (1996) ("[B]ecause the States are independent sovereigns in our federal
    system, we have long presumed that Congress does not cavalierly pre-empt
    state-law causes of action."); Cipollone, 505 U.S. at 516 ("Consideration
    of issues arising under the Supremacy Clause 'start[s] with the assumption
    that the historic police powers of the States [are] not to be superseded by
    . . . Federal Act unless that [is] the clear and manifest purpose of
    Congress.' " (quoting Rice v. Santa Fe Elevator Corp., 
    331 U.S. 218
    , 230
    (1947))).  This presumption has "add[ed] force" when there has been a "long
    history of tort litigation" in the area of state common law at issue.
    Bates v. Dow Agrosciences LLC, 
    544 U.S. 431
    , 449 (2005).
    ¶   8.     Defendant concedes that Congress has not expressly
    preempted state tort actions through the Food, Drug and Cosmetics Act
    (FDCA), 21 U.S.C. ¶¶ 301-399, and that Congress did not intend the FDCA
    to occupy the entire field of prescription drug regulation.  Rather, it
    asserts that plaintiff's action "actually conflicts with federal law."
    Cipollone, 505 U.S. at 516.  This requires defendant to show either that
    "it is impossible for a private party to comply with both state and federal
    requirements," or that Vermont's common law "stands as an obstacle to the
    accomplishment and execution of the full purposes and objectives of
    Congress."  Freightliner Corp. v. Myrick, 
    514 U.S. 280
    , 287 (1995)
    (quotations and citations omitted).
    ¶   9.     Defendant presents two alternative bases for its assertion
    of conflict preemption: (1) in the specific context of the Phenergan label,
    the FDA was aware of the dangers of IV-push administration and specifically
    ordered defendant to use the warning it used, making it impossible for
    defendant to comply with both its state common-law duty and the
    requirements of federal law; and (2) by penalizing drug companies for using
    FDA-approved wording on drug labels, state tort claims like plaintiff's
    present an obstacle to the purpose of the FDA's labeling regulations.
    Before reaching these issues, we briefly examine the FDA's role in
    regulating prescription drug labels and the general approach courts have
    taken to the preemptive effect of federal labeling requirements.
    A.     Regulatory Background
    ¶   10.     Prior to distributing a prescription drug such as
    Phenergan, the manufacturer must submit a New Drug Application (NDA) for
    FDA approval.  21 U.S.C. ¶ 355(a).  The FDA must approve the application
    unless it fails to meet certain criteria, including whether test results
    and other information establish that the drug is "safe for use under the
    conditions prescribed, recommended, or suggested in the proposed labeling
    thereof," whether there is "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 proposed labeling
    thereof," and whether, "based on a fair evaluation of all material facts,
    such labeling is false or misleading in any particular."  Id. ¶ 355(d).
    ¶   11.     "FDA regulations mandate the general format and content of
    all sections of labels for all prescription drugs as well as the risk
    information each section must contain," and "[f]inal approval of the NDA is
    '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 label prior to marketing.' "  McNellis v. Pfizer,
    Inc., 
    2005 WL 3752269
    , at *4 (D.N.J.) (citing 21 C.F.R. ¶¶ 201.56,
    201.57, and quoting 21 C.F.R. ¶ 314.105(b)).  Once a drug and its label
    have been approved, any changes to the label ordinarily require submission
    and FDA approval of a "Supplemental NDA."
    Id.; 21 C.F.R. ¶ 314.70(b)(2)(v)(A).
    ¶   12.     If the NDA process and the submission of changes for FDA
    approval were the exclusive means of creating and altering prescription
    drug labels, this might be a very different case.  A key FDA regulation,
    however, allows a drug's manufacturer to alter the drug's label without
    prior FDA approval when necessary.  The regulation provides in relevant
    part:
    (6) The agency 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.  These changes
    include, but are not limited to:
    . . . .
    (iii) Changes in the labeling . . . to accomplish any of the
    following:
    (A)     To add or strengthen a contraindication, warning,
    precaution, or adverse reaction;
    . . . .
    (B)     To add or strengthen an instruction about dosage and
    administration that is intended to increase the safe use of
    the drug product[.]
    21 C.F.R. ¶ 314.70(c).
    ¶   13.     Section 314.70(c) creates a specific procedure allowing
    drug manufacturers to change labels that are insufficient to protect
    consumers, despite their approval by the FDA.  "The FDA's approved label .
    . . can therefore be said to set the minimum labeling requirement, and not
    necessarily the ultimate label where a manufacturer improves the label to
    promote greater safety."  McNellis, 
    2005 WL 3752269
    , at *5.  While specific
    federal labeling requirements and state common-law duties might otherwise
    leave drug manufacturers with conflicting obligations, ¶ 314.70(c) allows
    manufacturers to avoid state failure-to-warn claims without violating
    federal law.  Id.  ("[I]t is apparent that prior FDA approval need not be
    obtained, nor will a product be deemed mislabeled, if the manufacturer
    voluntarily or even unilaterally strengthens the approved warnings,
    precautions or potential adverse reactions upon the label pursuant to 21
    C.F.R. ¶ 314.70(c)(6)(iii)(A).").  There is thus no conflict between
    federal labeling requirements and state failure-to-warn claims.  Section
    314.70(c) allows, and arguably encourages, manufacturers to add and
    strengthen warnings that, despite FDA approval, are insufficient to protect
    consumers.  State tort claims simply give these manufacturers a concrete
    incentive to take this action as quickly as possible.
    B.  Conflict Preemption in Other Jurisdictions
    ¶   14.     In light of the leeway created by ¶ 314.70(c) for drug
    manufacturers to add warnings, courts have been nearly unanimous in holding
    that state failure-to-warn tort claims do not conflict with federal law.
    See, e.g., McNellis, 
    2005 WL 3752269
    , at *7 ("[T]he FDCA and the FDA's
    regulations do not conflict with New Jersey's failure to warn law because
    those federal regulations merely set minimum standards with which
    manufacturers must comply.").  McNellis is the latest in a series of recent
    cases addressing this issue as it relates to the anti-depressant Zoloft,
    which allegedly increases the risk of suicide in some patients.  See id.,
    at *7-8 (denying summary judgment and rejecting conflict preemption in
    Zoloft case); accord Zikis v. Pfizer, Inc., 
    2005 WL 1126909
    , at *2-3 (N.D.
    Ill.); Witczak v. Pfizer, Inc., 
    377 F. Supp. 2d 726
    , 729-30 (D. Minn.
    2005); Motus v. Pfizer, Inc., 
    127 F. Supp. 2d 1085
    , 1096-1100 (C.D. Cal.
    2000); see also Cartwright v. Pfizer, Inc., 
    369 F. Supp. 2d 876
    , 882 (E.D.
    Tex. 2005) ("With little exception, courts that have considered this exact
    issue have concluded that state failure to warn claims are not preempted by
    the FDCA and its attendant regulations.").  Contra Needleman v. Pfizer,
    Inc., 
    2004 WL 1773697
    , at *1 (N.D. Tex.) (granting summary judgment to the
    defendant on basis of conflict preemption).
    ¶   15.     The Zoloft cases are representative of a general rule that
    FDA approval of a drug's label does not preempt state failure-to-warn
    claims.  See, e.g., Eve v. Sandoz Pharm. Corp., 
    2002 WL 181972
    , at *1-3
    (S.D. Ind.) (rejecting conflict preemption of failure-to-warn claim
    regarding the drug Parlodel); Caraker v. Sandoz Pharm. Corp., 
    172 F. Supp. 2d
     1018, 1032 (S.D. Ill. 2001) (same); Bryant v. Hoffman-La Roche, Inc.,
    
    585 S.E.2d 723
    , 725 (Ga. Ct. App. 2003) (heart medication); Bell v. Lollar,
    
    791 N.E.2d 849
    , 854-55 (Ind. Ct. App. 2003) (prescription pain medication);
    Kurer v. Parke, Davis & Co., 
    2004 WI App 74
    ,  21, 
    679 N.W.2d 867
     (oral
    contraceptive).  But see Ehlis v. Shire Richwood, Inc., 
    233 F. Supp. 2d 1189
    , 1198 (D.N.D. 2002) (granting summary judgment to defendant on basis
    of conflict preemption of claim regarding the drug Adderall).
    ¶   16.     Defendant cites two cases, Needleman and Ehlis, that
    support the preemptive effect of the FDCA in failure-to-warn cases
    regarding prescription drug labels.  Needleman, 
    2004 WL 1773697
    , at *1;
    Ehlis, 233 F. Supp. 2d at 1198.  Needleman is not particularly helpful
    under the circumstances here.  Its holding relied on the facts of the
    Zoloft litigation, particularly an FDA statement that the warning advocated
    by the plaintiff would have been misleading.  
    2004 WL 1773697
    , at *1.  The
    courts in the other Zoloft cases took a different approach to the FDA's
    statement, in part because the FDA's statement was not "an official agency
    position," and in part because the FDA later retracted its position
    regarding the link between Zoloft and suicide.  See, e.g., Witczak, 377 F.
    Supp. 2d at 730.  Here, the FDA has not indicated that a stronger warning
    would be misleading, so the reasoning of Needleman appears inapplicable to
    this case.  Ehlis interpreted ¶ 314.70(c) as allowing unapproved changes
    to a label only temporarily, and only under "limited circumstances."  233
    F. Supp. 2d at 1197-98.  We can find no support for this interpretation in
    the language of the regulation, which appears to allow unilateral changes
    to drug labels whenever the manufacturer believes it will make the product
    safer, and places no limit on the duration of pre-approval warnings unless
    the FDA disapproves of the change.  21 C.F.R. ¶ 314.70(c).
    ¶   17.     Defendant next attempts to draw a comparison to the
    regulation of medical devices under the FDCA, citing medical device cases
    in which state tort law has been preempted.  See Buckman Co. v. Plaintiffs'
    Legal Comm., 
    531 U.S. 341
    , 348 (2001) (holding that "fraud-on-the-FDA"
    claim relating to device regulated by Medical Device Amendments to FDCA was
    preempted); Horn v. Thoratec Corp., 
    376 F.3d 163
    , 177 (3d Cir. 2004)
    (holding that failure-to-warn claim was preempted by Medical Device
    Amendments).  We find this analogy unpersuasive.  Neither Buckman nor Horn
    weakens the force of the drug-labeling cases cited above.  The claim that
    was preempted in Buckman was for "fraud on the FDA," not failure to warn;
    the Court held that the presumption against preemption applies only when a
    claim implicates " 'the historic primacy of state regulation of health and
    safety,' " which is not the case when the claim arises from a federal
    statute.  531 U.S. at 347-48 (quoting Medtronic, 518 U.S. at 485).
    Plaintiff's negligence and product-liability claims fall squarely within
    the scope of traditional state regulation, so it is appropriate to apply
    the presumption against preemption here.   In Horn, the Third Circuit
    relied on an express preemption clause in the FDCA that relates only to
    medical devices.  376 F.3d at 176.  Because no such clause exists for
    prescription drugs, Horn's reasoning does not apply to this case.
    ¶   18.     Finally, defendant cites a third group of cases relating
    generally to the United States Supreme Court's recent use of conflict
    preemption in other fields.  This argument relies primarily on Geier v.
    American Honda Motor Co., 
    529 U.S. 861
     (2000).  In Geier, the Court held
    that state tort claims based on the production of automobiles without
    airbags conflicted with federal regulations making airbags one of several
    permissible safety equipment options.  529 U.S. at 881.  Geier, however,
    rested on the conclusion that the Department of Transportation's intent in
    drafting the regulation at issue was to provide a range of different safety
    options, thus precluding any state determination that a specific type of
    equipment should be required.  Id.  The history of the regulation at issue
    indicated that the agency intended to phase in automobile safety
    requirements gradually, allowing the public to choose between mandatory
    seatbelt laws at the state level and a federal passive-restraint
    requirement.  Id. at 880-81.  Allowing state tort claims based on the lack
    of a particular safety mechanism would have conflicted with both the
    agency's phase-in plan and its intent to provide consumers with a range of
    safety options.  Id. at 881.  The Court explicitly stated that in a
    different context, an agency could promulgate regulations that provided a
    floor, but not a ceiling, for state regulation.  Id. at 870.
    ¶   19.     The FDA's labeling requirements are exactly that type of
    regulation.  Section 314.70(c) does not allow us to interpret FDA approval
    of a drug label as anything but a first step in the process of warning
    consumers.  When further warnings become necessary, the manufacturer is at
    least partially responsible for taking additional action, and if it fails
    to do so, it cannot rely on the FDA's continued approval of its labels as a
    shield against state tort liability.  While a state common-law duty may
    encourage departure from a label that the FDA has approved in great detail,
    such a duty does not create a conflict with federal requirements because
    the FDA and the state share the purpose of encouraging pharmaceutical
    companies to alter their drug labels when they are inadequate to protect
    consumers.  We agree with the significant majority of courts that state
    failure-to-warn claims are generally not preempted by federal labeling
    requirements.
    ¶   20.     We must now apply this reasoning to defendant's two
    original contentions: (1) notwithstanding the fact that it is generally
    possible for manufacturers to comply with both federal and state law
    through the procedures created by ¶ 314.70(c), the FDA's specific actions
    with respect to Phenergan made it impossible for defendant to comply with
    both federal and state law; and (2) even if plaintiff's claim and the cases
    cited above do not make it impossible for manufacturers to comply with both
    state and federal law, they present an obstacle to federal objectives.
    C.  Impossibility of Compliance
    ¶   21.     Defendant contends that in this case, it was impossible to
    comply with both state and federal law because the FDA prohibited the use
    of a stronger warning with respect to IV-push administration of Phenergan.
    This claim is not supported by the evidence defendant presented to the
    trial court.  The record lacks any evidence that the FDA was concerned that
    a stronger warning was not supported by the facts, that such a stronger
    warning would distract doctors from other provisions in the drug's label,
    or that the warning might lead to less effective administration of the
    drug.  Instead, defendant essentially relies on two factual assertions: 1)
    the FDA approved the label that was in use in 2000; and 2) the FDA, in
    reviewing the label for use in a different version of Phenergan, expressed
    its opinion of the adequacy of the warning in the original label by
    stating, "Retain verbiage in current label."  AB 5, 5 n.7
    ¶   22.     With respect to defendant's first assertion, our analysis
    above demonstrates that FDA approval of a particular label does not preempt
    a jury finding that the label provided insufficient warning, as defendant
    was free under ¶ 314.70(c) to strengthen the warning without prior FDA
    approval.  Defendant's second assertion depends on the meaning of the
    instruction, "[r]etain verbiage in current label."  Tort liability for
    defendant's failure to strengthen its warning could have created a direct
    conflict requiring federal preemption only if the FDA intended the
    instruction to prohibit any language strengthening the original warning.
    In other words, unless we interpret the FDA's statement as evidence that it
    would have rejected any attempt by defendant to strengthen its label
    through ¶ 314.70(c), we cannot conclude that it was impossible for
    defendant to comply with its state common-law duty without violating
    federal law.
    ¶   23.     Defendant argues that the instruction reflected the FDA's
    opinion not only that a stronger warning was unnecessary, but also that it
    would have harmed patients by eliminating IV push as an option for
    administering Phenergan.  The record does not support this interpretation.
    Defendant has provided a number of letters exchanged by the FDA and
    defendant regarding Phenergan's label, but these letters do not indicate
    the FDA's opinion of the value of IV-push administration.  Neither the
    letters nor any other evidence presented to the jury indicated that the FDA
    wished to preserve the use of IV push as a method of administering
    Phenergan.  Nor can we infer such concern from the agency's instruction to
    "[r]etain current verbiage" instead of adopting the proposed warning.  The
    specific warning the agency rejected in favor of the original label did not
    indicate any more clearly than the original label that IV-push
    administration was unsafe, which is what plaintiff argued made the original
    label inadequate.  The FDA could have rejected the new warning for any
    number of reasons, including clarity or technical accuracy, without
    implicitly prohibiting a stronger warning.  Defendant's unsupported
    hypothesis that the FDA saw the new warning as harmful seems among the
    least likely explanations, as the rejected proposal would not have
    eliminated IV push as an option for administering Phenergan.(FN2)  With
    respect to IV administration, the original label read, "When administering
    any irritant drug intravenously it is usually preferable to inject it
    through the tubing of an intravenous infusion set that is known to be
    functioning satisfactorily," while the proposed label stated, "[i]njection
    through a properly running intravenous infusion may enhance the possibility
    of detecting arterial placement.  In addition, this results in delivery of
    a lower concentration of any arteriolar irritant."  See supra  4 n.1
    (comparing proposed and original warnings).  Simply stated, the proposed
    warning was different, but not stronger.  It was also no longer or more
    prominent than the original warning, so it could not have raised a concern
    that it might overshadow other warnings on the label or drive doctors away
    from prescribing the drug.  There is no evidence that the FDA intended to
    prohibit defendant from strengthening the Phenergan label pursuant to ¶
    314.70(c).(FN3)  Thus, we cannot conclude that it was impossible for
    defendant to comply with its obligations under both state and federal law.
    D. Obstacle to Congressional Purposes and Objectives
    ¶   24.     Defendant next contends that state common-law liability
    for its use of an FDA-approved label presents an obstacle to federal
    objectives.  We hold that plaintiff's claim does not interfere with any
    objective that can legitimately be ascribed to Congress.  We agree with the
    reasoning in the cases cited above, supra  14-15, that federal labeling
    requirements pursuant to the FDCA create a floor, not a ceiling, for state
    regulation.  Defendant presents a new FDA rule containing language
    disputing this reasoning, but this statement does not alter our conclusion
    that there is no conflict between federal objectives and Vermont common
    law.
    1. The Purposes and Objectives of Congress
    ¶   25.     In the absence of a conflict that makes it impossible for
    a regulated entity to comply with both state and federal law, federal law
    will preempt state law only if it "stands as an obstacle to the
    accomplishment and execution of the full purposes and objectives of
    Congress."  Freightliner, 514 U.S. at 287 (quotations omitted).  We must
    therefore examine what "the full purposes and objectives of Congress" were
    with respect to federal labeling requirements for prescription drugs.  We
    agree with the McNellis court that a system under which "federal
    regulations merely set minimum standards with which manufacturers must
    comply" is
    fully consistent with Congress' primary goal in enacting the
    FDCA, which is "to protect consumers from dangerous
    products," United States v. Sullivan, 
    332 U.S. 689
    , 696
    (1948), as well as Congress' stated intent that the FDCA "
    'must not weaken the existing laws,' but on the contrary 'it
    must strengthen and extend that law's protection of the
    consumer.' "  United States v. Dotterweich, 
    320 U.S. 277
    [,
    282] (1943) [quoting S. Rep. No. 152, 75th Cong., 1st Sess.,
    p. 1].
    
    2005 WL 3752269
    , at *7; see also Witczak, 377 F. Supp. 2d at 731 ("Congress
    certainly did not intend to bar drug companies from protecting the public
    when enacting the FDCA;  its goal was to protect the public. . . . Any
    contrary interpretation of Congress's intent is perverse.").
    ¶   26.     In fact, Congress has expressed its purposes clearly, not
    only in the general sense that the statute was intended to "protect the
    public," but also more specifically, with respect to the FDCA's preemptive
    effect.  In the 1962 amendments to the FDCA, Congress included a clause
    expressly limiting the preemptive effect of the statute: "Nothing in the
    amendments made by this Act to the Federal Food, Drug, and Cosmetic Act
    shall be construed as invalidating any provision of State law . . . unless
    there is a direct and positive conflict between such amendments and such
    provision of State law."  Drug Amendments of 1962 (Harris Kefauver Act),
    Pub. L. No. 87 781, ¶ 202, 76 Stat. 780, 793 (1962).
    ¶   27.     This amendment essentially removes from our consideration
    the question of whether common-law tort claims present an obstacle to the
    purposes and objectives of Congress.  Congress intended that the FDCA would
    leave state law in place except where it created a "direct and positive
    conflict" between state and federal law.  Drug Amendments ¶ 202.  This
    language "simply restates the principle that state law is superseded in
    cases of an actual conflict with federal law such that 'compliance with
    both federal and state regulations is a physical impossibility.' " See S.
    Blasting Servs., Inc. v. Wilkes County,  
    288 F.3d 584
    , 591 (4th Cir. 2002)
    (interpreting "direct and positive conflict" language in the preemption
    clause of a federal statute governing explosive materials to allow states
    to "impose more stringent requirements than those contained in the federal
    regulations") (quoting Hillsborough County v. Automated Med. Labs., Inc.,
    
    471 U.S. 707
    , 713 (1985)).(FN4)   In other words, under any circumstances
    where it is possible to comply with both state law and the FDCA, the state
    law in question is consistent with the purposes and objectives of Congress.
    Thus, our discussion above regarding defendant's impossibility argument,
    supra  21-23, provides a complete answer to the question of preemption.
    ¶   28.     We recognize that our dissenting colleague has reached the
    opposite conclusion.  There is little to say, beyond what we have already
    said, except that we respectfully disagree with his analysis of the FDCA,
    the FDA's regulations, and the specific context of this lawsuit.  Numerous
    courts have concluded, over the course of decades, that the FDCA provides a
    floor, not a ceiling, for state regulation.  See supra,  14-15.  While the
    dissent cites favorably the minority view, we agree with the majority view.
    There is much to be said for the policy arguments employed by courts
    adopting this minority view, including the argument that permitting too
    much state activity in this area will make beneficial drugs less available
    to consumers.  Similarly, there is merit to the majority perspective that
    eliminating lawsuits like the one at issue here would leave consumers
    without recourse in the event the FDA cannot move quickly enough to require
    strengthened warnings when they are appropriate.  Our view is that neither
    policy argument is relevant here.  The plain language of the statute
    indicates that Congress did not intend to interfere with state prerogatives
    except where doing so is absolutely necessary, see supra,  25-27, and the
    plain language of the regulation makes such interference unnecessary here,
    see supra,  12-13.  This analysis is consistent with the constitutionally
    rooted presumption against preemption.  To look more broadly at arguments
    relying on assumptions about safety and economic efficiency is to apply the
    opposite presumption-the presumption that Congress could not possibly have
    intended to allow states to intrude on what seems, intuitively, to be an
    area of federal expertise.  It is neither our responsibility, nor that of
    the FDA, to question the policy judgments of Congress.  The litigation at
    issue here does not pose a direct and positive conflict with federal law,
    and thus, there is no basis for federal preemption.
    2.  The FDA's New Statement on Preemption
    ¶   29.     Defendant, after oral argument in this case, cited a new
    FDA regulation that contains a statement relating to the preemptive effect
    of the FDCA.  The substance of the regulation changes certain aspects of
    labeling requirements for prescription drugs, but these changes are
    irrelevant to this appeal because the new rule did not take effect until
    June 2006.  Food and Drug Administration, Requirements on Content and
    Format of Labeling for Human Prescription Drug and Biological Products,
    Supplementary Information, 71 Fed. Reg. 3922, 3922 (Jan. 24, 2006).  The
    rule's "Supplementary Information" section, however, contains a broad
    statement regarding the preemption of state common-law failure-to-warn
    claims.  Id. at 3933-36.  In this statement, the FDA asserts that recent
    cases rejecting preemption of these claims, including those cited above,
    pose an obstacle to the agency's enforcement of the labeling requirements.
    Id.  Among the interpretations the agency claims are incorrect are: (1)
    those rejecting preemption on the basis of ¶ 314.70(c); and (2) those
    stating that federal labeling requirements are minimum standards and that
    "[s]tate law serves as an appropriate source of supplementary safety
    regulation for drugs by encouraging or requiring manufacturers to
    disseminate risk information beyond that required by FDA under the act."
    Id. at 3934.
    ¶   30.     We are ordinarily required to defer to an agency's
    interpretation of a statute it administers.  Chevron, U.S.A., Inc. v.
    Natural Res. Def. Council, 
    467 U.S. 837
    , 844 (1984) ("We have long
    recognized that considerable weight should be accorded to an executive
    department's construction of a statutory scheme it is entrusted to
    administer . . . .").  Plaintiff, however, urges us not to defer to the
    FDA's statement because it "was adopted without the requisite comment
    period" and "lack[s] the force of law."  Presumably, if we were to credit
    plaintiff's argument, we would owe the statement only the limited deference
    due to agency statements made outside the agency's rulemaking authority.
    See United States v. Mead Corp., 
    533 U.S. 218
    , 226-27 (2001) (stating that
    Chevron deference applies only "when it appears that Congress delegated
    authority to the agency generally to make rules carrying the force of law,
    and that the agency interpretation claiming deference was promulgated in
    the exercise of that authority").  We need not decide this difficult
    question of administrative law, however, because we conclude that
    irrespective of the level of deference we might apply, the statement would
    not affect the outcome of this appeal.
    ¶   31.     Under Chevron, deference to an agency's interpretation is
    appropriate only when a statute is "silent or ambiguous with respect to the
    specific issue" the agency has considered; otherwise, "the court, as well
    as the agency, must give effect to the unambiguously expressed intent of
    Congress."  467 U.S. at 842-43.  Moreover, "[t]he judiciary is the final
    authority on issues of statutory construction and must reject
    administrative constructions which are contrary to clear congressional
    intent."  Id. at 843 n.9.  "If a court, employing traditional tools of
    statutory construction, ascertains that Congress had an intention on the
    precise question at issue, that intention is the law and must be given
    effect."  Id.  When an agency's interpretation is not the type of
    interpretation entitled to Chevron deference, we must still grant it some
    respect, but only "a respect proportional to its 'power to persuade.' "
    Mead, 533 U.S. at 235 (quoting Skidmore v. Swift & Co., 
    323 U.S. 134
    , 140
    (1944)).
    ¶   32.     Under either standard, the FDA's statement deserves no
    deference.  We have already concluded, supra  26-27, that Congress intended
    the FDCA to preempt only those state laws that would make it impossible for
    manufacturers to comply with both federal and state requirements.  Nothing
    in the FDA's new statement alters our conclusion that it would be possible
    for defendant to comply with both its federal obligations and the
    obligations of state common law.  The regulatory framework for prescription
    drug labeling allows drug manufacturers to add or strengthen a warning "to
    increase the safe use of the drug product" without prior FDA approval.  See
    supra  10-13 (citing 21 C.F.R. ¶ 314.70(c)(6)(iii)(C)).  Even if the new
    rule eliminated or altered this provision, the change in the regulation did
    not take effect until June 2006.(FN5)  Without such a change, it is possible
    for manufacturers to comply with both FDA regulations and duties imposed by
    state common law, and there is no "direct and positive conflict" between
    state and federal law.
    ¶   33.     The FDA does not attempt to establish such a conflict or
    explain the inconsistency between its position and the language of the
    preemption amendment.  The statement cites the amendment, but then proceeds
    as if Congress had not spoken on the issue of preemption.  The agency
    relies on Geier to support its disregard of Congress's "direct and positive
    conflict" language, asserting that "[t]he existence of a legislative
    provision addressing pre-emption does not bar the operation of ordinary
    principles of implied preemption."  71 Fed. Reg. at 3935 (citing Geier, 529
    U.S. at 869).  Geier does state that implied preemption applies even when a
    statute addresses preemption expressly, 521 U.S. at 869, but it does not
    allow courts or agencies to preempt state laws that have been expressly
    preserved by Congress.  Instead, it simply stands for the proposition that
    Congress's intent not to preempt a provision of state law cannot be
    inferred from either (1) an express preemption clause that does not include
    the state law in question in its scope, or (2) a clause that prevents
    regulated entities from using compliance with federal law as a defense in
    state common-law suits.  Id. at 869-70.  According to Geier, the former
    clause does not support a negative inference that Congress must have
    intended to preserve laws it did not expressly preempt; the latter
    indicates only that Congress intended to preserve some common-law claims,
    not that it intended to allow even claims that conflict with federal
    requirements.  Id.  But see id. at 870 (stating that even the latter clause
    would "preserve[] those actions that seek to establish greater safety than
    the minimum safety achieved by a federal regulation intended to provide a
    floor").
    ¶   34.     Here, we are not attempting to infer the effect of
    statutory language that only indirectly addresses the specific state law at
    issue.  Instead, we are interpreting an unambiguous express preemption
    clause that specifically preserves the type of state law at issue.  Under
    these circumstances, ordinary preemption principles must give way to
    Congress's intent to preserve state laws that do not create a "direct and
    positive conflict" with federal law.  Drug Amendments ¶ 202.  There is no
    such conflict here.  Accordingly, the FDA's statement is neither an
    authoritative interpretation of an ambiguous statutory provision entitled
    to deference, Chevron, 467 U.S. at 842-43, nor a persuasive policy
    statement entitled to respect.  Mead, 533 U.S. at 235.  Plaintiff's claim
    does not impose conflicting obligations on defendant or present an obstacle
    to the objectives of Congress.  We therefore agree with the trial court
    that the claim is not preempted by federal law.
    II.  Apportionment of Damages
    ¶   35.     Defendant next contends the court erred by failing to
    instruct the jury to reduce plaintiff's damages by the amount of fault
    attributable to the Health Center.  "Reversing a jury verdict based on
    allegedly faulty jury instructions is warranted where the party claiming
    error establishes that the instructions were erroneous and prejudicial."
    Simpson v. Rood, 
    2005 VT 21
    ,  5, 
    178 Vt. 474
    , 
    872 A.2d 306
     (mem.).  We hold
    that there was no error in the court's failure to require apportionment of
    damages between defendant and the Health Center.
    ¶   36.     Defendant argues that pursuant to Vermont's comparative
    negligence statute, a defendant is liable for only the portion of the
    plaintiff's damages attributable directly to that defendant's negligence.
    12 V.S.A. ¶ 1036.  Our traditional rule is that multiple tortfeasors are
    jointly and severally liable.  See Zaleskie v. Joyce, 
    133 Vt. 150
    , 158, 
    333 A.2d 110
    , 115 (1975) ("[T]he law of this state . . . permits a plaintiff to
    pursue all, or any part, of his recovery from either joint tortfeasor").
    According to defendant, ¶ 1036 applies not only under circumstances where
    comparative negligence is alleged on the part of the plaintiff, and not
    only when multiple defendants are sued in the same action, but also any
    time the plaintiff recovers from someone besides the defendant.  Thus,
    because plaintiff and the Health Center reached a settlement in a separate
    lawsuit related to the same injury, defendant claims the jury should have
    been required to calculate the Health Center's proportion of causal
    negligence and subtract that percentage from the verdict.
    ¶   37.     Section 1036 states, under the heading of "Comparative
    negligence,"
    Contributory negligence shall not bar recovery in an action
    by any plaintiff, or his legal representative, to recover
    damages for negligence resulting in death, personal injury or
    property damage, if the negligence was not greater than the
    causal total negligence of the defendant or defendants, but
    the damage shall be diminished by general verdict in
    proportion to the amount of negligence attributed to the
    plaintiff.  Where recovery is allowed against more than one
    defendant, each defendant shall be liable for that proportion
    of the total dollar amount awarded as damages in the ratio of
    the amount of his causal negligence to the amount of causal
    negligence attributed to all defendants against whom recovery
    is allowed.
    12 V.S.A. ¶ 1036.  We interpreted this statute under slightly different
    circumstances in Plante v. Johnson, 
    152 Vt. 270
    , 
    565 A.2d 1346
     (1989).  In
    Plante, the defendant resisted joinder of the plaintiffs' claims against
    her and a third party, resulting in a joint trial with two separate
    verdicts.  The jury first returned a verdict against the third party for
    the entire amount of the plaintiff's damages, then found against the
    defendant for the same amount, and the court consolidated the judgments.
    The defendant appealed, arguing that the first verdict made the third
    party's share of the fault 100%.  She concluded that under ¶ 1036, she
    was entitled to a ruling apportioning 100% of the liability for the
    plaintiff's damages to the third party.  The defendant failed to argue this
    point at trial, making a holding regarding ¶ 1036 unnecessary.  We
    nevertheless examined the statute in depth to demonstrate that our
    determination that the defendant was not entitled to apportionment was
    "more than a technical omission."  Id. at 272, 565 A.2d at 1347.  We
    concluded that the statute did not apply to the defendant in Plante because
    "the statute provides for apportionment among defendants, suggesting that
    only those joined in the same action should be considered in apportioning
    damages," and "there is no allegation that the plaintiff was negligent in
    this case."(FN6)  Id. at 273, 565 A.2d at 1347-48.
    ¶   38.     In reaching this conclusion, we relied in part on the fact
    that "the New Hampshire Supreme Court has held that its nearly identical
    statute does not apply to create several liability in the absence of an
    allegation of negligence on the part of the plaintiff."  Id., 565 A.2d at
    1348 (citing Lavoie v. Hollinracke, 
    513 A.2d 316
    , 319-20 (N.H. 1986)).
    Defendant points out that Lavoie has since been overruled, but the decision
    overruling it, Nilsson v. Bierman, 
    839 A.2d 25
     (N.H. 2003), relied on a
    legislative revision of New Hampshire's statute that placed the concepts of
    comparative negligence and apportionment under separate headings.  Id. at
    29.  In the absence of action by the Legislature to amend Vermont's
    comparative negligence statute, we see no reason to depart from the
    interpretation of ¶ 1036 contained in Plante.  The Health Center was not
    a party to plaintiff's action against defendant, and defendant does not
    allege that plaintiff was comparatively negligent, so ¶ 1036 does not
    apply in this case.
    ¶   39.     Defendant argues that whether or not ¶ 1036 applies, we
    can depart from our common law and determine that joint and several
    liability should no longer prevent apportionment among joint tortfeasors
    when one tortfeasor has settled in a previous action.  We decline to do so.
    In Howard v. Spafford, 
    132 Vt. 434
    , 
    321 A.2d 74
     (1974), which also involved
    an interpretation of ¶ 1036, we expressed our hesitation to depart from
    the rule precluding contribution among joint tortfeasors, preferring not to
    "substitute judicial fiat for legislative action."  Id. at 435, 321 A.2d at
    75.  Among the many reasons cited in Howard for adhering to the common law
    was the sheer number of alternative schemes adopted by other states.  Id.
    at 436-37, 321 A.2d at 75-76.  This reasoning applies here as well.  Our
    choice is not between the traditional rule and a uniform new rule, but
    rather between a traditional rule and a number of potential new rules or
    combinations of rules.  The Nilsson court pointed out the divide among
    states requiring jury verdicts to be reduced by the dollar amount of the
    plaintiff's settlement with a third party (pro tanto), those requiring
    verdicts to be reduced by the percentage of the settling party's fault
    (proportional share), and those requiring verdicts to be divided among all
    joint tortfeasors equally (pro rata).  839 A.2d 30-31.  That court pointed
    out that while "[t]he American Law Institute favors the proportional share
    approach . . . , the overwhelming majority of States reject the
    proportional share approach in favor of some version of the pro tanto
    approach," and New Hampshire's legislature chose a combination of the two.
    Id. at 31 (citations and quotations omitted).  It is important to note that
    if we were to adopt the majority rule, our decision would have no effect on
    this case, as plaintiff and defendant have stipulated to a pro tanto
    reduction.  Like the New Hampshire court, we will allow the Legislature to
    determine which approach is best, if it has not done so already by leaving
    ¶ 1036 in place after our interpretation in Plante.
    III.  Present Value of Damages
    ¶   40.     Finally, defendant contends the court erred by failing to
    instruct the jury to calculate the present value of plaintiff's damages for
    future non-economic losses, such as pain and suffering.  Defendant claims
    that the jury's verdict, which granted plaintiff $5 million in non-economic
    damages, exceeded the present value of plaintiff's requested amount by
    $856,073.  In rejecting defendant's proposed instruction, the court pointed
    out that defendant failed to provide the jury with expert guidance as to
    how present value should be calculated, and that "[j]udges and lawyers are
    universally incapable of performing the discount calculations with or
    without a calculator and the tables of historic interest rates and
    inflationary factors."  We agree that it would have been inappropriate to
    instruct the jury to make such a calculation under these circumstances.
    ¶   41.     Even if defendant had presented testimony allowing the
    jury to make an informed calculation, we would have upheld the jury's
    verdict for several reasons.  First, defendant's assertion that the jury
    did not take account of the present value of plaintiff's non-economic
    damages is pure speculation, as plaintiff's calculation of her economic
    damages was presented in terms of its present value, and "the jury was not
    required to demonstrate its calculations" with respect to plaintiff's
    non-economic damages.  Debus v. Grand Union Stores of Vt., 
    159 Vt. 537
    ,
    543, 
    621 A.2d 1288
    , 1292 (1993).  Second, we limit pre-judgment interest to
    economic damages because non-economic damages are "inchoate and rarely
    ascertainable at the time of injury."  Turcotte v. Estate of LaRose, 
    153 Vt. 196
    , 200 n.2, 
    569 A.2d 1086
    , 1088 n.2 (1989).  These damages become no
    less inchoate following a judgment, and we will not require juries to apply
    a precise economic calculation to a figure we have identified as inherently
    imprecise.
    ¶   42.     Finally, most jurisdictions and the Restatement (Second)
    of Torts reject the concept of requiring juries to make present-value
    calculations with respect to non-economic damages.  See, e.g., Taylor v.
    Denver & Rio Grande W. R.R., 
    438 F.2d 351
    , 353 (10th Cir. 1971) (holding
    that instruction requiring present-value reduction for pain and suffering
    was error and stating that most courts that have considered the issue have
    decided "that the better reasoned authority supports the rule that future
    pain and suffering should not be reduced to current worth"); Restatement
    (Second) of Torts ¶ 913A cmt. a (1979) (stating that while future
    pecuniary losses should be reduced to present value, "an award for future
    pain and suffering or for emotional distress is not discounted in this
    fashion").  But see Olivieri v. Delta S.S. Lines, Inc., 
    849 F.2d 742
    ,
    750-51 (2d Cir. 1988) (stating that "[i]f we were writing on a clean slate,
    we might be inclined to accept the view of the other circuits and reject
    any discounting of future non pecuniary losses," but previous Second
    Circuit holdings required such discounting in some form).  Defendant's
    reliance on our decision in Parker v. Roberts, 
    99 Vt. 219
    , 
    131 A.2d 21
    (1925), is misplaced, as Parker, while it required a jury instruction on
    the present value of future losses, did not address the distinction between
    pecuniary and non-pecuniary losses.  Id. at 224-25, 131 A.2d at 23.  The
    trial court did not err in refusing to instruct the jury to reduce
    plaintiff's non-economic damages to present value.

    Associate Justice
    ------------------------------------------------------------------------------
    Dissenting
    ¶   43.     REIBER, C.J., dissenting.  The overarching issue in this
    appeal is whether plaintiff's common-law claim for failure to warn
    conflicts with the FDA's regulation of Phenergan, the drug responsible for
    plaintiff's injuries.  I would conclude that the jury's verdict in this
    case conflicts with federal law for two reasons.
    ¶   44.     First, it would be impossible for defendant Wyeth to
    comply with the requirements of both state and federal law.  Specifically,
    the FDA approved IV administration of Phenergan and required that IV
    administration be listed on the Phenergan label.  By contrast, plaintiff's
    theory of the case required Wyeth either to remove this approved use from
    the Phenergan label, add a warning that would directly contradict the
    label's indication that IV administration was a safe and effective use, or,
    at a minimum, add a warning that only certain types of IV administration
    should be used.  Thus, compliance with state law in this case would require
    Wyeth to eliminate uses of Phenergan approved by the FDA and required to be
    included in the Phenergan labeling.
    ¶   45.     Second, plaintiff's state-law claim conflicts with federal
    law in that it poses an obstacle to federal purposes and objectives.  In
    short, by approving Phenergan for marketing and distribution, the FDA
    concluded that the drug-with its approved methods of administration and as
    labeled-was both safe and effective.  See 21 U.S.C. ¶ 355(d) (listing
    criteria for drug approval).  In finding defendant liable for failure to
    warn, a Vermont jury concluded that the same drug-with its approved methods
    of administration and as labeled-was "unreasonably dangerous."  See Town of
    Bridport v. Sterling Clark Lurton Corp., 
    166 Vt. 304
    , 308, 
    693 A.2d 701
    ,
    704 (1997) (to succeed on failure-to-warn claim, plaintiff must show that
    "failure to warn made the product unreasonably dangerous and therefore
    defective").  These two conclusions are in direct conflict.
    ¶   46.     For both of these reasons I would conclude that the
    state-law cause of action is preempted.  I respectfully dissent.
    I.  Impossibility of Compliance
    ¶   47.     As explained by the majority, because there is no clause
    in the FDCA expressly preempting state law, Wyeth must demonstrate that
    preemption is implied by showing either that federal law thoroughly
    occupies the regulatory field (a claim that Wyeth does not advance) or that
    there is an actual conflict between state and federal law.  Actual
    conflict, in turn, can be demonstrated in one of two ways: by showing that
    it is impossible for the regulated party to comply with both state and
    federal law or that state law "stands as an obstacle to the accomplishment
    and execution of the full purposes and objectives of Congress."
    Freightliner Corp. v. Myrick, 
    514 U.S. 280
    , 287 (1995) (quotations
    omitted).
    ¶   48.     The majority in essence concludes that it is not
    impossible for Wyeth to comply with both federal and state standards
    because Wyeth never sought FDA approval of a "stronger warning" of the type
    advocated by plaintiff.  According to the majority, because the FDA was not
    presented with, and therefore did not explicitly reject, such strengthened
    language, there is no reason to presume that the FDA would disapprove.
    Therefore, the majority reasons, there is no actual conflict between state
    and federal law.  See ante ¶ 21-22.  It is inaccurate, however, to
    characterize the requirements imposed by the jury verdict in this case as
    merely requiring a "stronger warning."  Rather, what plaintiff sought was
    an elimination of a use of Phenergan that had been approved by the FDA.
    Furthermore, the FDA's rejection of Wyeth's efforts to alter the language
    of the warning in 2000 supports Wyeth's claim that the FDA had an
    affirmative preference for the language of the original warning.
    A.
    ¶   49.     The crux of plaintiff's claim was not based on the label
    warnings per se, but on the approved uses listed there.  See, e.g., ante ¶ 3
    ("Plaintiff's experts testified that the label should not have allowed IV
    push as a means of administration . . ..").  A review of plaintiff's
    complaint and the evidence presented at trial makes clear that the standard
    plaintiff sought to establish (i.e., the change to the label that would be
    required in light of the jury's finding of liability) was to remove IV
    administration-or at least certain types-as an approved use.  For example,
    plaintiff's complaint asserted that the warnings on the label were
    inadequate and that:
    [t]he Phenergan sold by defendant is . . . NOT REASONABLY
    SAFE FOR INTRAVENOUS ADMINISTRATION because the foreseeable
    risks of harm posed by intravenous administration of the drug
    are sufficiently great in relation to its foreseeable
    theraputic benefits that reasonable health care providers,
    knowing of such foreseeable risks and benefits, WOULD NOT
    PRESCRIBE THE DRUG INTRAVENOUSLY FOR ANY CLASS OF PATIENTS."
    (Emphasis added.)  In her appellate brief, plaintiff characterizes the
    evidence as revealing "that Wyeth was aware of research indicating that
    DIRECT IV ADMINISTRATION OF PHENERGAN WAS UNSAFE."  (Emphasis added.)
    Plaintiff further refers to expert testimony "that the LABEL SHOULD HAVE
    RESTRICTED PHENERGAN TO INTRAMUSCULAR INJECTIOn as this method of
    administration presents no risk of inadvertent arterial injection; or,
    alternatively, that if IV administration is used, it must be by injecting
    the Phenergan into a hanging IV bag, not through a direct IV."  (Emphasis
    added.)
    ¶   50.     Here, the FDA clearly addressed the risks attending IV
    administration of the drug. The label approved IV administration generally,
    and specifically warned of the dangers of direct IV administration,
    including inadvertent arterial injection possibly resulting in amputation.
    In light of this, it cannot be argued that the FDA did not (1) assess the
    risk of IV administration, including direct IV administration and the
    associated risk of amputation due to inadvertent arterial injection;  (2)
    conclude that the benefits of allowing IV administration with appropriate
    warnings outweighed the risk; and (3) reach a decision regarding precisely
    what warning language should be used.  These assessments are, in fact, the
    very essence of the FDA's approval and are in furtherance of the federal
    objective of advancing public health by balancing the risks and benefits of
    new drugs and facilitating their optimal use.  See 21 U.S.C. ¶ 355(d)
    (listing factors to be considered in approving or refusing new drug
    application); 21 U.S.C. ¶ 393(b)(1), (b)(2)(B) (FDA is charged with
    promoting public health by acting promptly on new drug applications and
    protecting public health by ensuring that new drugs are both safe and
    effective).
    ¶   51.     The majority  reconciles this manifest conflict by relying
    on 21 C.F.R. ¶ 314.70(c), which allows a drug manufacturer to alter a
    label "[t]o add or strengthen a contraindication, warning, precaution, or
    adverse reaction" or "add or strengthen an instruction about dosage and
    administration" prior to FDA approval.(FN7)  On this basis, the majority
    concludes that Wyeth "was free under ¶ 314.70(c) to strengthen the
    warning without prior FDA approval."  Ante ¶ 22.  But, it is an
    overstatement to claim that manufacturers are "free" to change drug labels
    under ¶ 314.70(c).  To the contrary, a manufacturer may change a label
    only to add or strengthen a warning, not to eliminate an approved use, as
    plaintiff would require here.  In other words, what plaintiff advocates is
    not a stronger warning but language that would directly contradict language
    approved and mandated by the FDA.
    ¶   52.     Further, the apparent purpose of ¶ 314.70(c) is to allow
    manufacturers to address newly-discovered risks.  See 44 Fed. Reg. 37434,
    37447 (June 26, 1979) (allowing supplement to label "whenever possibly
    harmful adverse effects associated with the use of the drug are
    discovered").  Even courts that conclude that ¶ 314.70(c) provides
    manufacturers broad latitude to add warnings to labels acknowledge that
    such supplements are aimed at previously unknown and unanalyzed risks.  See
    McNellis v. Pfizer, Inc., 
    2005 WL 3752269
    , at *6 (D.N.J.) (concluding that
    ¶ 314.70(c) "was promulgated precisely to allow drug manufacturers to
    quickly strengthen label warnings when evidence of new side effects [is]
    discovered") (citing 30 Fed. Reg. 993 (Jan. 20, 1965));  Kurer v. Parke,
    Davis & Co., 
    2004 WI App 74
    ,  18, 
    679 N.W.2d 867
     (noting that, under ¶
    314.70(c), "[d]rug manufacturers can strengthen warnings or petition for
    additional warnings when new risk information arises").  Another section of
    the regulation makes clear that any changes to a label that exceed the
    scope of ¶ 314.70(c) are considered "major changes" that require prior
    approval before the drug may be distributed.  ¶ 314.70(b), (b)(2)(v).  In
    short, the regulation does not allow manufacturers to simply reassess and
    draw different conclusions regarding the same risks and benefits already
    balanced by the FDA.  Here, the FDA had already evaluated the risk of
    inadvertent arterial injection from direct IV administration of Phenergan,
    and had mandated warning language for the label to reflect that risk
    assessment.
    ¶   53.     In addition, any change accomplished under ¶ 314.70(c)
    is subject to ultimate FDA review and approval.  See ¶ 314.70(c)(7)
    (providing that FDA may order manufacturer to cease distribution of drug if
    it disapproves supplemental application); see also Needleman v. Pfizer,
    Inc., 
    2004 WL 1773697
    , at *3 (N.D. Tex. 2004) (noting that changes to label
    under ¶ 314.70(c) are temporary and "must later be approved by the FDA").
    Thus, any additional or different warnings must ultimately be supported by
    scientific research that meets the FDA's standards.  Neither a
    manufacturer, a state court, nor a state legislature can permanently
    substitute its judgment of the risk-benefit analysis for that of the FDA.
    ¶   54.     At its core, plaintiff's argument in this case was not
    that the warnings on the label were inadequate, but that an approved use
    (direct IV administration) was in fact unreasonably unsafe.  Plaintiff did
    not seek to "add or strengthen" a warning or a dosage/administration
    instruction, but rather to eliminate an approved use of the drug.  This is
    a disagreement that cannot be overcome by operation of ¶ 314.70(c).
    Plaintiff's claim in this case-that a method of administration of the drug
    should be partially if not entirely eliminated from the labeling-represents
    a substantive disagreement with FDA policy that goes beyond
    labeling/warning issues alone.  This disagreement creates opposing
    requirements and a manufacturer could not satisfy both at once.
    B.
    ¶   55.     Wyeth argues that even if ¶ 314.70(c) theoretically
    allows a manufacturer to make unilateral changes to a drug label, in this
    case, the FDA actually rejected Wyeth's attempts in 2000 to change the
    warning regarding intra-arterial injection and amputation.  The trial court
    concluded that the FDA gave only "passing attention" to the risks of IV
    administration in 2000.  Ante ¶ 4.  The majority similarly concludes that
    the record does not indicate "that the FDA wished to preserve the use of IV
    push as a method of administering Phenergan."  Ante ¶ 23.  I cannot agree
    with this assessment of the record.
    ¶   56.     Both the original label and Wyeth's proposed alternative
    were titled "INADVERTENT INTRA-ARTERIAL INJECTION."  On the original label,
    the first two sentences of the warning read:
    Due to the close proximity of arteries and veins in the areas
    most commonly used for intravenous injection, extreme care
    should be exercised to avoid perivascular extravasation or
    inadvertent intra-arterial injection.  Reports compatible
    with inadvertent intra-arterial injection of [Phenergan],
    usually in conjunction with other drugs intended for
    intravenous use, suggest that pain, severe chemical
    irritation, severe spasm of distal vessels, and resultant
    gangrene requiring amputation are likely under such
    circumstances.
    On the proposed label, the first sentence of the warning read: "There are
    reports of necrosis leading to gangrene, requiring amputation, following
    injection of [Phenergan], usually in conjunction with other drugs; the
    intravenous route was intended in these cases, but arterial or partial
    arterial placement of the needle is now suspect."  While the proposed
    change to the warning language may not reflect what plaintiff would require
    in a warning, it cannot be disputed that Wyeth's proposed alternative
    warning (1) placed greater emphasis on the risk of necrosis and amputation
    by referencing it in the first sentence, and (2) gave the FDA the
    opportunity to consider the specific, alternative warning advanced by
    Wyeth, as well as the adequacy of the warning in general.  Despite this
    opportunity, the FDA mandated that Wyeth retain the language of the
    existing warning.   The alleged extent of the FDA's consideration of the
    issue is not relevant, in my view.
    ¶   57.     In 2000, the FDA confirmed its assessment that health care
    professionals should be permitted to choose IV administration in its
    various forms as a means of delivering the drug, where appropriate.  Wyeth
    could not both list all forms of IV administration as an approved use, as
    required by the FDA, and exclude all or some forms of IV administration as
    unsafe, as required by the jury's verdict in this case.  It would be
    impossible to comply with both requirements.
    II. Obstacle to Federal Purposes and Objectives
    ¶   58.     I would further conclude that Wyeth has demonstrated
    actual conflict preemption by showing that plaintiff's state-law
    failure-to-warn claim poses an obstacle to federal purposes and objectives.
    The majority does not address this issue, concluding that Wyeth does not
    have the option of proving this form of actual conflict preemption.  The
    majority reaches this conclusion by relying on the following clause in the
    1962 amendments to the FDCA:
    Nothing in the Amendments made by this Act to the Federal
    Food, Drug, and Cosmetic Act shall be construed as
    invalidating any provision of State law . . . unless there is
    a direct and positive conflict between such amendments and
    such provision of state law.
    Ante ¶ 26 (quoting Drug Amendments of 1962 (Harris Kefauver Act), Pub. L.
    No. 87 781, ¶ 202, 76 Stat. 780, 793 (1962)).  Citing Southern Blasting
    Services, Inc. v. Wilkes County,  
    288 F.3d 584
    , 591 (4th Cir. 2002), the
    majority concludes that the provision "essentially removes from our
    consideration the question of whether common-law tort claims present an
    obstacle to the purposes and objectives of Congress," because the 1962
    provision "simply restates the principle that state law is superseded in
    cases of actual conflict with federal law such that compliance with both
    federal and state regulations is a physical impossibility."  Ante ¶ 27
    (internal quotations omitted).  "In other words," the majority explains,
    "under any circumstances where it is possible to comply with both state law
    and the FDCA, the state law in question is consistent with the purposes and
    objectives of Congress."  Id.  Thus, the majority eliminates the
    possibility of proving actual conflict preemption independently through the
    "obstacle" prong of that standard.
    ¶   59.     But neither the passage in Southern Blasting on which the
    majority relies nor the  United States Supreme Court decision (FN8) cited
    as authority in that passage provide an explanation or even an affirmative
    statement that the phrase "direct and positive conflict" in the 1962
    amendment eliminates the "obstacle" prong of the actual conflict preemption
    standard.  Thus, the majority eliminates one of the two means by which
    Wyeth may show actual conflict based on a single, unclearly-reasoned Fourth
    Circuit decision that is itself lacking in case law support.  There is no
    basis for eliminating this prong of the actual conflict standard, and I
    disagree with the majority's conclusion to the contrary.(FN9)
    ¶   60.     Assuming, then, that Wyeth may demonstrate actual conflict
    preemption by showing that state law is an obstacle to federal regulatory
    purposes and objectives, I believe the facts here support the conclusion
    that the state tort-law verdict in this case is preempted.  The United
    States Supreme Court's decision in Geier v. American Honda Motor Co., 
    529 U.S. 861
     (2000), is controlling on the question of when state law poses an
    obstacle to federal purposes and objectives.  In that case, the Department
    of Transportation had issued a safety standard that required automobile
    manufacturers "to equip some but not all of their 1987 vehicles with
    passive restraints."  Id. at 864-65.  Among the optional passive restraints
    were air bags.  Honda was in compliance with this standard.  Nonetheless,
    the plaintiff was seriously injured in a car accident while driving a 1987
    Honda that was not equipped with an air bag, but with another form of
    passive restraint.  The plaintiff brought suit, alleging Honda was
    negligent in failing to install a driver's-side air bag in the car.  Honda
    argued that the federal safety standard preempted the plaintiff's state-law
    negligence claim.  The Supreme Court held that a lawsuit premising
    negligence on the failure to install an air bag conflicted with the
    objectives of the federal safety standard and was therefore preempted.  Id.
    at 866.
    ¶   61.     In reaching this conclusion, the Court noted that the
    plaintiff and the dissenting opinion-like the majority in the instant
    case-viewed the federal regulation as setting a minimum safety standard
    that states were free to supplement or strengthen.  Id. at 874.  However,
    by examining the comments accompanying the regulation, the Court concluded
    that a safety standard allowing a choice of passive restraint systems while
    not mandating any particular system was a deliberate decision that
    reflected a balance of diverse policy concerns.  See id. at 875 (noting
    that allowing mix of available safety devices available over time would
    "lower costs, overcome technical safety problems, encourage technological
    development, and win widespread consumer acceptance").  "In sum, . . . the
    1984 version of [the safety standard] embodies the Secretary's judgment
    that safety would best be promoted if manufacturers installed alternative
    protection systems in their fleets rather than one particular system in
    every car." Id. at 881 (quotations omitted).  Accordingly, the Court
    concluded that the tort action sought to impose a duty on manufacturers to
    impose air bags, rather than other types of passive restraint systems, and
    that this state-law requirement was an obstacle to the federal objective of
    allowing a mix of safety devices.
    ¶   62.     Application of the Supreme Court precedent in Geier
    dictates the same result in this case.  As with the DOT in Geier, the FDA
    is primarily concerned with public safety.  The conclusion of what is best
    for public safety is arrived at by considering various policy factors that
    are sometimes in tension with one another.  For example, in developing the
    safety regulation at issue in Geier, the DOT considered not only which
    passive-restraint systems were safest on an absolute scale, but which were
    most cost-effective and which would gain consumer acceptance.  Similarly,
    here the FDA balances its assessment of a drug's safety against concerns
    for the drug's efficacy, taking into account that a safer but less
    effective drug is not necessarily best for the public health overall.  See
    21 U.S.C. ¶ 355(d) (FDA must consider safety and efficacy); 21 U.S.C. ¶
    393(b)(1), (b)(2)(B) (FDA's mission is to protect public from unsafe drugs
    and to promote public health by approving regulated products in timely
    manner).   In the specific context oarnings on drug labels, the FDA
    considers not only what information to include, but also what to exclude.
    As the Eighth Circuit has noted in the medical device context, "[t]here are
    . . . a number of sound reasons why the FDA may prefer to limit warnings on
    product labels."  See Brooks v. Howmedica, Inc., 
    273 F.3d 785
    , 796 (8th
    Cir. 2001).  For example, "warnings about dangers with less basis in
    science or fewer hazards could take attention away from those that present
    confirmed, higher risks."  Id.
    ¶   63.     No drug is without risks.  The FDA balances the risks of a
    drug against its benefits to maximize the availability of beneficial
    treatments.  The FDA's decision in approving a drug, its uses and labeling
    reflect consideration of these and other policy factors.  While a
    state-court jury presumably shares the FDA's concern that drugs on the
    market be reasonably safe, the jury does not assess reasonableness in the
    context of public health and the associated risk-benefit analysis.  A jury
    does not engage in a measured and multi-faceted policy analysis.  Rather, a
    jury views the safety of the drug through the lens of a single patient who
    has already been catastrophically injured.  Such an approach is virtually
    guaranteed to provide different conclusions in different courts about what
    is "reasonably safe"  than the balancing approach taken by the FDA.  In
    act, different conclusions were reached in this case.
    ¶   64.     The jury in this case was instructed that "[a]
    prescription drug is unreasonably dangerous due to inadequate warnings or
    instructions if reasonable instructions regarding foreseeable risks of harm
    are not provided to the physician and other medical professionals who are
    in a position to reduce the risks of harm."  Faced with plaintiff's tragic
    injuries, the jury concluded that allowing Phenergan to be delivered
    through IV administration was "unreasonably dangerous."  The jury's verdict
    conflicts squarely with the FDA's assessment of precisely the same issue:
    whether Phenergan is safe and effective when delivered through IV
    administration.  The claim is preempted.
    ¶   65.     For the above reasons, I dissent.

    Footnotes
    FN1.  The warning on the label that was in use in 2000 read in relevant
    part:
    INADVERTENT INTRA-ARTERIAL INJECTION: Due to the close
    proximity of arteries and veins in the areas most commonly
    used for intravenous injection, extreme care should be
    exercised to avoid perivascular extravasation or inadvertent
    intra-arterial injection.  Reports compatible with
    inadvertent intra-arterial injection of [Phenergan], usually
    in conjunction with other drugs intended for intravenous use,
    suggest that pain, severe chemical irritation, severe spasm
    of distal vessels, and resultant gangrene requiring
    amputation are likely under such circumstances.  Intravenous
    injection was intended in all the cases reported but
    perivascular extravasation or arterial placement of the
    needle is now suspect.  There is no proven successful
    management of this condition after it occurs . . . .
    When used intravenously [Phenergan] should be given in a
    concentration no greater than 25 mg per ml and at a rate not
    to exceed 25 mg per minute.  WHEN ADMINISTERING ANY IRRITANT
    DRUG INTRAVENOUSLY IT IS USUALLY PREFERABLE TO INJECT IT
    THROUGH THE TUBING OF AN INTRAVENOUS INFUSION SET THAT IS
    KNOWN TO BE FUNCTIONING SATISFACTORILY.
    (Emphasis added.) The revised warning the FDA failed to adopt read in
    relevant part:
    INADVERTENT INTRA-ARTERIAL INJECTION: There are reports of
    necrosis leading to gangrene, requiring amputation, following
    injection of [Phenergan], usually in conjunction with other
    drugs; the intravenous route was intended in these cases, but
    arterial or partial arterial placement of the needle is now
    suspect. . . .
    There is no established treatment other than prevention:
    1.  Beware of the close proximity of arteries and veins
    at commonly used injection sites and consider the possibility
    of aberrant arteries.
    2.  When used intravenously, [Phenergan] should be given
    in a concentration no greater than 25 mg/ml and a rate not to
    exceed 25 mg/minute.  INJECTION THROUGH A PROPERLY RUNNING
    INTRAVENOUS INFUSION MAY ENHANCE THE POSSIBILITY OF DETECTING
    ARTERIAL PLACEMENT.  IN ADDITION, THIS RESULTS IN DELIVERY OF
    A LOWER CONCENTRATION OF ANY ARTERIOLAR IRRITANT.
    (Emphasis added.)
    FN2.  The dissent appears to interpret any warning that would eliminate
    IV-push administration as inherently inconsistent with the FDA's approval
    of Phenergan for IV administration in general.  We see no such
    inconsistency, as an approval of a drug for IV administration is not the
    same as a conclusion that all methods of IV administration are safe.  In
    any case, a jury verdict in a failure-to-warn case simply establishes that
    the relevant warning was insufficient; it does not mandate a particular
    replacement warning.  There may have been any number of ways for defendant
    to strengthen the Phenergan warning without completely eliminating IV-push
    administration.  Our purpose in pointing out that the proposed warning the
    FDA rejected did not eliminate IV push is simply that rejecting this
    warning could not be seen as an affirmative effort by the FDA to preserve
    IV push as an option.
    FN3.   We also reject defendant's argument that it would have been
    prosecuted for "misbranding" if it had strengthened the label without prior
    approval.  See Witczak, 377 F. Supp. 2d at 731, 729 ("[T]he validity and
    authority of state law . . . does not depend on speculative hypotheticals"
    regarding "assumptions of what the FDA would have done" in response to a
    stronger warning.).
    FN4.  The debate surrounding the amendment helps confirm that it was
    intended to preserve the right of states to regulate beyond the federal
    requirements of the FDCA.  During the floor debate in the House, the
    subject of preemption arose several times.  First, Congressman Smith of
    California expressed concern that the bill, as reported, contained "no
    language . . . which says anything to the effect that this particular
    measure will not preempt all State food and drug laws," and thus, might
    risk interfering with the efforts of some states to make their own,
    stricter regulations.  108 Cong. Rec. 21046 (1962) ("[I]t seems to me that
    if we are going to pass this law, someone ought to offer an amendment to
    make certain that the passage of this bill, which gives all of this power
    to the Department of Health, Education, and Welfare and the Food and Drug
    Administration, will not preempt any State laws").  Shortly thereafter,
    Congressman Harris of Arkansas, the primary House sponsor of the bill,
    offered his opinion that "there is nothing in this bill that in any way
    preempts the authority and prerogatives of the States."  Id. at 21047.
    Congressman Schenck of Ohio agreed, stating, "[m]any very helpful State
    laws are in effect; many such laws in some instances are even stronger than
    Federal laws for the protection of human health in the public interest."
    Id. at 21056.
    Congressmen Schenck and Harris, despite insisting that the bill as written
    would not preempt stronger state laws, eventually supported the "direct and
    positive conflict" amendment, and Schenck reiterated that preemption should
    not apply in the "many instances where State laws in the area of food and
    drugs and health are even stronger than some of the Federal laws."  Id. at
    21083.  Neither the desirability of allowing states to regulate beyond the
    FDCA nor the intent of the amendment to protect such regulation from
    preemption was called into question during the debate.
    FN5.  The only alteration the new rule appears to make to ¶ 314.70 is that
    changes to the new "Highlights" section of a drug label may not be made
    without prior approval.  71 Fed. Reg. at 3934.
    FN6.  We also listed as an additional reason, not applicable here, that the
    third party whose liability was at issue in Plante was held liable under a
    different theory of liability that was not clearly within the scope of ¶
    1036.  Id. at 273, 565 A.2d at 1348.
    FN7.  This is also the approach employed by the numerous federal district
    court decisions cited by the majority.  Ante ¶ 14.  Because I disagree with
    this analysis of the import of ¶ 314.70(c), I do not find these decisions
    to be persuasive.  Instead, I side with the minority view expressed in
    Needleman, which concludes that ¶ 314.70(c) gives manufacturers very little
    latitude in unilaterally revising drug labels.  Needleman v.  Pfizer, Inc.,
    
    2004 WL 1773697
    , at *3 (N.D. Tex.).
    FN8.  See Hillsborough v. Automated Med. Labs., 
    471 U.S. 707
    , 713 (1985).
    The cited passage in Hillsborough does not interpret the phrase "direct and
    positive conflict."  It merely cites the different forms of preemption,
    including the "obstacle" prong. It is worth noting that the federal statute
    at issue in Geier v. American Honda Motor Co., 
    529 U.S. 861
     (2000)
    (discussed below), contained an even broader savings clause than the 1962
    amendment to the FDCA.   The provision in Geier stated simply  that the
    federal safety standard at issue did "not exempt any person from any
    liability under common law."  Id. at 868.
    FN9.  Nonetheless, the Court concluded that all ordinary preemption
    principles-including actual conflict preemption and the obstacle prong of
    the standard-applied.  The Court rejected the notion that Congress would so
    limit the effect of preemption as to allow an actual conflict with a
    federal objective:  "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."    Id. at 872.
