    In Re: Reglan Litigation (075269) (A-56-14)
    Argued April 11, 2016 – Decided August 22, 2016
    ALBIN. J., writing for a unanimous Court.
    This appeal involves state-law claims of inadequate drug warnings asserted against certain generic drug
    manufacturers by individuals who took the drug metoclopramide, the generic form of Reglan. The Court determines
    whether plaintiffs’ state-law failure-to-warn claims under the New Jersey Product Liability Act (PLA), N.J.S.A.
    2A:58C-1 to -11, are preempted by federal law.
    In 2004, the brand-name manufacturer of Reglan received approval from the Food and Drug
    Administration (FDA) to publish new label warnings about the dangers of the long-term use of metoclopramide
    exceeding twelve weeks. Plaintiffs, who were prescribed and took metoclopramide after the FDA approved the
    upgraded warnings, claim that defendants, who are generic manufacturers of the drug, did not timely upgrade their
    label warnings to match the 2004 and 2009 FDA-approved brand-name label warnings. As a result, plaintiffs took
    metoclopramide beyond the prescribed period, which they contend caused them to develop severe neurological
    disorders.
    Plaintiffs commenced suit against defendants in state court through nearly 1,000 individual lawsuits against
    brand-name and generic manufacturers of metoclopramide. The action then proceeded through a master complaint
    covering all plaintiffs. Plaintiffs asserted claims under the PLA based on defendants’ failure to warn of the harmful
    effects of the long-term use of metoclopramide tablets. Plaintiffs assert that defendants failed to update their
    labeling and packaging inserts to match the FDA-approved warnings until long after those warnings were issued,
    which proximately caused the disorders which now afflict plaintiffs.
    Defendants moved to dismiss plaintiffs’ state-law claims as preempted by federal law. The trial court
    denied defendants’ motions for dismissal, finding that federal preemption did not apply because defendants had a
    duty under state law to provide adequate labeling, and the labeling that they provided failed to match the brand-
    name labeling. The Appellate Division affirmed the trial court’s determinations, finding that federal law did not
    preempt plaintiffs’ claims because they do not place state law and federal law in conflict. The appellate panel stated
    that plaintiffs’ claims are not premised on violations of federal law, but, rather, on defendants’ failure to give
    adequate warnings under the PLA, and that it was possible for defendants to comply with both state and federal law.
    This Court granted defendants’ motions for leave to appeal. 
    224 N.J. 278
    (2014).
    HELD: Plaintiffs’ state-law failure-to-warn claims under the PLA, based on the alleged inadequate labeling of
    metoclopramide which did not match the brand-name labeling and warn of the dangers of the long-term use of the
    drug, are not preempted by federal law, and may proceed before the trial court.
    1. The doctrine of federal preemption is founded on the Supremacy Clause of the United States Constitution. The
    doctrine recognizes that federal law shall be the Supreme Law of the land, notwithstanding any state law to the
    contrary. When Congress legislates in a field where states have traditionally exercised their historic police powers,
    the assumption is that Congress did not intend to supersede a state statute unless that was its clear and manifest
    purpose. A state law that conflicts with a federal statute is naturally preempted. Conflict preemption applies where
    compliance with both federal and state regulations is a physical impossibility, or where state law stands as an
    obstacle to execution of the full purposes and objectives of federal law. (pp. 15-16)
    2. Under the Federal Food, Drug and Cosmetic Act (FDCA), 21 U.S.C.A. §§ 301-399f, a manufacturer seeking
    federal approval to market a new drug must prove that it is safe and effective, and that the proposed label is accurate
    and adequate. Meeting the FDA’s approval requirements for a new drug involves costly and lengthy clinical testing,
    the costs of which are reflected in the price of prescription drugs. In 1984, Congress passed the Drug Price
    Competition and Patent Term Restoration (Hatch-Waxman) Act of 1981, Pub. L. No. 98-417, 98 Stat. 1585 (1984),
    with the goal of making generic drugs more affordable and accessible. Hatch-Waxman streamlined the process for
    the FDA’s approval of generic drugs. It allows a generic-drug manufacturer to gain FDA approval of a generic drug
    by demonstrating that it is identical in active ingredients, safety, and efficacy to a brand-name drug approved by the
    FDA. (pp. 17-18)
    3. Under the FDCA, a brand-name drug manufacturer is responsible for the accuracy and adequacy of a drug’s
    labeling, including when it seeks FDA approval for updated labeling to inform the public of previously unknown
    adverse side-effects from the drug. However, a generic drug manufacturer is responsible for ensuring only that its
    labeling is the same as the labeling approved for the brand-name drug. Under Hatch-Waxman, a generic drug
    manufacturer cannot deviate from the labeling used by the brand name drug; the warning label must always be the
    same. Because generic labeling must be the same as that of the brand-name drug, necessary updates to the labeling
    of a generic drug should be made at the earliest possible time. (pp. 18-20)
    4. The United States Supreme Court has recognized that, in adopting the FDCA, Congress did not intend to pre-
    empt common-law tort actions, and state tort law may serve as a complementary tool in regulating the warnings on
    prescription drugs that have potentially dangerous side effects. In particular, failure-to-warn suits lend force to the
    FDCA’s premise that manufacturers, rather than the FDA, bear primary responsibility for their drug labeling at all
    times. The PLA is an expression of New Jersey’s strong public policy of ensuring that manufacturers attach
    adequate warnings and instructions to prescription drugs so that consumers will know of the relevant risks, dangers,
    and precautions in taking such medications. The PLA provides that a warning or instruction approved under the
    FDCA would enjoy a rebuttable presumption of adequacy under state law. The PLA is a codification of tort-law
    principles in a field in which the state has traditionally exercised its historic police powers. Therefore, a failure-to-
    warn claim under the PLA is not preempted unless Congress has expressed its clear and manifest purpose to do so.
    (pp. 21-26)
    5. Plaintiffs’ state-law failure-to-warn claims against defendants are not preempted by federal law. Defendants did
    not conform their labeling to that of the brand-name drug, and therefore were in violation of the FDCA’s sameness
    requirement. Federal preemption is inapplicable because defendants did not have to violate federal law in order to
    comply with state law, and it was not impossible to comply with both federal and state law. Plaintiffs’ state law
    claims highlight the inadequacy of the warnings for a drug, which if used for a prolonged period, could cause grave
    harm. As a result, plaintiffs’ claims promote the full purposes and objectives of Congress in enacting the FDCA.
    The Court therefore affirms the judgment of the Appellate Division, which upheld the trial court’s denial of
    defendants’ motion to dismiss plaintiffs’ state-law failure-to-warn claims. (pp. 26-29)
    6. In order to obtain safe-harbor protection from state-law claims under the FDCA’s sameness doctrine, a generic
    drug manufacturer must exercise reasonable diligence to learn of updates to the brand-name labeling and to conform
    to the FDCA’s sameness requirement. Should a generic drug manufacturer do so, federal preemption may bar a
    state law failure-to-warn claim under the PLA. (p. 36)
    The judgment of the Appellate Division is AFFIRMED, and the matter is REMANDED to the trial court
    for further proceedings consistent with this opinion.

    1
    JUSTICE ALBIN delivered the opinion of the Court.
    In 2004, the brand-name manufacturer of Reglan, known
    generically as metoclopramide, received approval from the Food
    and Drug Administration (FDA) to publish new label warnings
    about the dangers of the long-term use of metoclopramide.
    Plaintiffs are individuals who took metoclopramide, the generic
    form of Reglan.     They claim that defendant generic drug
    manufacturers of metoclopramide did not timely upgrade their
    label warnings to match the FDA-approved brand-name labeling.
    Due to the allegedly inadequate generic drug warnings,
    plaintiffs took metoclopramide beyond the prescribed period,
    causing them to develop severe neurological disorders.
    Plaintiffs filed failure-to-warn product-liability actions
    against defendants in state court.     Relying on PLIVA, Inc. v.
    Mensing, 
    564 U.S. 604
    , 
    131 S. Ct. 2567
    , 
    180 L. Ed. 2d 580
    (2011), defendants argue that federal law preempts plaintiffs’
    state-law claims.
    In Mensing, the United States Supreme Court explained that,
    under federal law, generic drug manufacturers are obligated to
    provide the same warning labels as those provided by the brand-
    name manufacturer.     
    Id. at 612-13,
    131 S. Ct. at 2574, 180 L.
    Ed. 2d at 588-89.     On that basis, the Court concluded that
    federal law preempted state-law tort claims against generic drug
    manufacturers for failing to give warnings exceeding those on
    2
    brand-name labels.     
    Id. at 618,
    131 S. Ct. at 2577-78, 180 L.
    Ed. 2d at 592.   That conclusion followed because generic drug
    manufacturers could not comply with state law without violating
    federal law.   
    Ibid. The issue in
    this case is whether, under Mensing, a state-
    law failure-to-warn claim is preempted when a generic drug
    manufacturer gives warnings that are outdated and inferior to
    the manufacturer’s brand-name warnings approved by the FDA.
    The trial court denied defendants’ motions to dismiss
    plaintiffs’ failure-to-warn claims, and similarly denied
    defendants’ motions for summary judgment, finding that federal
    preemption did not apply because defendant had a duty under
    state law to provide adequate labeling, and here the labeling
    did not match the brand-name labeling.     The Appellate Division
    affirmed, holding that plaintiffs’ claims are not premised on
    violations of federal law, but rather on the failure to give
    adequate warnings under New Jersey’s product-liability law.
    We agree with the Appellate Division that plaintiffs’
    failure-to-warn claims do not put state law and federal law in
    conflict.   Had defendants provided the same labeling as the
    brand-name manufacturers, as required by federal law, defendants
    would have enjoyed a safe harbor.     Here, however, defendants did
    not provide the same warning labels that the FDA approved for
    the brand-name manufacturers.    As alleged, defendants’
    3
    inadequate labeling breached a duty of care under the New Jersey
    Product Liability Act (PLA), N.J.S.A. 2A:58C-1 to -11.
    Complying with both federal and state law was not impossible
    because, unlike in Mensing, defendants could have updated their
    labeling without violating the FDA’s sameness requirement.
    Plaintiffs’ claims arise under state law, not by the grace of a
    federal regulatory scheme.   Because plaintiffs’ failure-to-warn
    claims are not preempted by federal law, we affirm the judgment
    of the Appellate Division.

    This case began with the filing of nearly 1000 individual
    lawsuits against over fifty brand-name and generic manufacturers
    of metoclopramide.   This Court consolidated those individual
    cases, and the trial court issued a case management order to
    allow for the filing of a master complaint covering all
    plaintiffs.1   Defendants -- PLIVA Inc., Barr Pharmaceuticals,

    Actavis-Elizabeth LLC, Teva Pharmaceuticals USA, Inc., Mutual
    Pharmaceutical Company, Inc., and United Research Laboratories,

    that did not change their labeling to match the 2004 and 2009
    FDA-approved brand-name label warnings.2    Plaintiffs were
    prescribed and used metoclopramide tablets after the FDA
    approved upgraded warnings in 2004.   Plaintiffs’ claims are
    premised on defendants’ failure to warn of the harmful effects
    of the long-term use of metoclopramide tablets.
    Metoclopramide is a prescription drug used for the
    treatment of symptomatic, gastroesophageal reflux and for relief

    accompanying packaging inserts for metoclopramide tablets is not
    disputed and is set forth in Mensing and, in part, in
    plaintiffs’ amended master complaint.    In 1980, the brand-name
    manufacturer of Reglan obtained approval from the FDA to market
    metoclopramide tablets.    Id. at 
    609, 131 S. Ct. at 2572
    , 180 L.
    Ed. 2d at 586.   Since that time, “warning labels for the drug
    have been strengthened and clarified several times.”    Id. at
    
    609, 131 S. Ct. at 2572
    , 
    180 L. Ed. 2d
    at 587.   In 1985, the FDA
    approved a label modification, warning that “‘[t]ardive
    dyskinesia . . . may develop in patients treated with
    metoclopramide,’ and the drug’s package insert added that
    ‘[t]herapy longer than 12 weeks has not been evaluated and
    cannot be recommended.’”   
    Ibid. (alterations in original)
    (quoting Physician’s Desk Reference 1635-36 (41st ed. 1987)).

    groups,” Taber’s Cyclopedic Medical Dictionary 746 (22d ed.

    In 2004, the then brand-name manufacturer secured the FDA’s
    approval for a labeling change of Reglan tablets.   The updated
    labeling warned in the “Indications and Usage” section that
    “[t]herapy should not exceed 12 weeks in duration,” and in the
    6
    “Dosage and Administration” section that “[t]herapy with
    [R]eglan tablets should not exceed 12 weeks in duration.”    In
    2009, the FDA issued “a black box warning -- its strongest --
    which state[d]:   ‘Treatment with metoclopramide can cause
    tardive dyskinesia, a serious movement disorder that is often
    irreversible. . . .    Treatment with metoclopramide for longer
    than 12 weeks should be avoided in all but rare cases.’”

    180 L. Ed. 2d
    at 587.
    Plaintiffs allege in their complaint that defendant generic
    manufacturers of metoclopramide tablets, through the early part
    of 2009, did not update their labeling and packaging inserts to
    match the FDA-approved warnings until long after those warnings
    were issued.
    Defendant Actavis-Elizabeth asserts that its metoclopramide
    shipments contained the labeling change as of January 4, 2005 --
    six months after the FDA approved revised warnings.    Defendant
    Teva Pharmaceuticals asserts that its metoclopramide shipments
    contained the labeling change as of July 28, 2005 -- one year
    after the revised warnings.    Defendants Mutual Pharmaceutical
    Company and United Research Laboratories assert that their
    metoclopramide shipments contained that labeling change as of
    January 31, 2006 -- one-and-one-half years after the revised
    warnings.    Defendant PLIVA claims that it was not informed of
    7
    the FDA-approved brand-name-label update through the end of 2008
    -- that is, through the four-and-one-half-year period it
    continued to manufacture metoclopramide.   In December 2008,
    defendant Watson Laboratories acquired the right from PLIVA to
    manufacture metoclopramide tablets.   Watson received notice from
    the FDA on November 30, 2009, of the approved brand-name black-
    box warning.   Watson repackaged its metoclopramide with the
    black-box warning more than ten months later, beginning October
    18, 2010.
    Plaintiffs claim that as a result of defendants’ failure to
    update the warnings for metoclopramide tablets, they took the
    drug beyond its prescribed period, causing them to develop
    tardive dyskinesia or other movement disorders.   See id. at 
    609, 131 S. Ct. at 2572
    , 
    180 L. Ed. 2d
    at 586 (“Evidence has
    accumulated that long-term metoclopramide use can cause tardive
    dyskinesia, . . . [and] [s]tudies have shown that up to 29% of
    patients who take metoclopramide for several years develop this
    condition.”) (citing McNeil v. Wyeth, 
    462 F.3d 364
    , 370 n.5 (5th
    Cir. 2006)).   According to plaintiffs, “[d]efendants knew or
    should have known that the metoclopramide products cause
    unreasonable, dangerous side-effects,” and defendants’ failure
    to give adequate warnings -- the 2004 and 2009 FDA-approved
    warnings -- proximately caused the disorders that have afflicted
    8
    plaintiffs.4
    B.
    The trial court denied defendants’ various motions to
    dismiss plaintiffs’ failure-to-warn claims on federal-preemption
    grounds.5   The court maintained that federal law required
    defendant generic manufacturers of metoclopramide tablets to
    adopt the brand-name labeling changes approved by the FDA.
    Thus, the state tort-law duty of generic manufacturers to give
    adequate warnings about the dangers of prolonged use of
    metoclopramide -- consistent with brand-name-labeling changes --
    did not conflict with federal law.   The court declined to extend
    the Mensing federal-preemption doctrine to “generic
    4 Based on the representations of defendants in the summary-
    judgment record, it appears that Watson Laboratories is the only
    defendant that may have violated the 2009 FDA warnings.
    5 The trial court dismissed a number of plaintiffs’ claims that
    are not relevant to this appeal. A detailed rendition of the
    procedural history is not necessary for our purposes.
    Defendants initially filed motions to dismiss on the basis that
    plaintiffs had “fail[ed] to state a claim upon which relief can
    be granted,” R. 4:6-2(e), and other motions later on the basis
    that the record as developed entitled them to an entry of
    summary judgment, R. 4:46-2(c). In a Rule 4:6-2(e) motion, the
    court reviews the complaint to determine whether the allegations
    suggest a cause of action, see Printing Mart-Morristown v. Sharp
    Elecs. Corp., 
    116 N.J. 739
    , 746 (1989) (quoting Velantzas v.
    Colgate-Palmolive Co., 
    109 N.J. 189
    , 192 (1988)), whereas in a
    Rule 4:46-2(c) motion, a court reviews the evidence of record
    “in the light most favorable to the non-moving party” to
    determine whether the moving party is entitled to judgment as a
    matter of law. See Brill v. Guardian Life Ins. Co. of Am.,

    manufacturers of metoclopramide tablets [that] failed to update
    the labels to be the same as the brand-name label.”
    Following discovery, defendants moved for summary judgment,
    claiming that they updated the metoclopramide tablet warnings to
    conform to those of the brand-name labeling and did so within a
    reasonable time.   The court denied summary judgment, finding
    that genuine issues of material fact remained concerning whether
    defendants had timely updated the warnings and whether the
    prior-used warnings were adequate.
    The Appellate Division denied defendants’ motion for leave
    to appeal.   Thereafter, we granted defendants leave to appeal
    and remanded to the Appellate Division for consideration of the
    merits of defendants’ arguments.
    C.
    In an unpublished opinion, the Appellate Division affirmed
    the trial court’s denial of defendants’ motions to dismiss for
    failure to state a claim and for summary judgment regarding
    plaintiffs’ failure-to-warn actions.   The appellate panel found
    that federal law did not preempt plaintiffs’ state-law claims
    that were premised on defendants’ “failure to update their
    warnings to conform to changes made to the brand-name warnings.”
    The panel, moreover, held that allowing plaintiffs to proceed
    with their state-law product-liability claims based on
    defendants’ failure to provide adequate warnings about the
    10
    dangers of prolonged metoclopramide use would not frustrate
    federal law.   It concluded that preemption did not apply in this
    case because it was possible for the generic drug manufacturers
    to comply with both state and federal law.      Last, the panel
    rejected the argument that Cornett v. Johnson & Johnson, 
    211 N.J. 362
    (2012), supports the dismissal of plaintiffs’ failure-
    to-warn claims.   It maintained that Cornett barred state-law
    claims that interfered with the FDA’s exclusive authority to
    enforce federal law.    Here, according to the panel, the state-
    law failure-to-warn claims fall “within a traditional area of
    state concern and regulation” and are not premised solely on a
    violation of federal law, quoting 
    Cornett, supra
    , 211 N.J. at
    390.
    We granted defendants’ motion for leave to appeal.    In re
    Reglan Litig., 
    224 N.J. 278
    (2014).      We also granted the motion
    of Amneal Pharmaceuticals, LLC, Par Pharmaceuticals Co., Inc.,
    Sandoz, Inc., and Wes-Ward Pharmaceuticals Corp., which filed a
    joint brief, to participate as amici curiae.

    Defendants contend that plaintiffs’ state-law claims are
    barred by the doctrine of federal preemption and that Mensing
    “marked the end of state-law product liability failure-to-warn
    claims involving generic drugs.”      They argue that the source of
    11
    their duty to update their labeling to conform to the FDA-
    approved labeling is the Federal Food, Drug, and Cosmetic Act
    (FDCA), 21 U.S.C.A. §§ 301-399f.       They claim that, under 21
    U.S.C.A. § 337, the federal government, not a private party, is
    authorized to initiate a suit for noncompliance with the FDCA
    and state courts cannot impose liability under state law for
    violations of federal law.    Defendants maintain that state law
    does not require “a generic drug manufacturer to match its
    labeling to the corresponding brand product.”      Invoking Mensing,
    defendants insist that “generic drug manufacturers have only a
    federal duty of ‘sameneness’ and not a duty of ‘adequacy.’”
    According to defendants, “[p]ermitting plaintiffs to proceed on
    purported state-law claims of ‘adequacy’ after a brand-name
    drug’s label is revised is tantamount to permitting plaintiffs
    to enforce the federal duty of ‘sameness’” in contravention of
    federal law.    Defendants’ overarching premise is that
    “plaintiffs may not frustrate Congress’s purposes and objectives
    in vesting [the] FDA with exclusive authority to regulate
    generic drug labeling, under the guise of a state-law claim.”
    The amici curiae pharmaceutical companies echo defendants’
    arguments.     Their principal position is that the state-law
    failure-to-warn claims are really “failure-to-timely-update”
    claims to enforce the federal duty of sameness under the FDCA.
    They view the Appellate Division and trial court decisions as an
    12
    end run around federal preemption.   They maintain that the FDA,
    not a jury impaneled in a state court, is in the best position
    to determine whether a generic drug manufacturer has made a
    timely labeling change to conform to the brand-name label and to
    impose sanctions under federal law if it has not.
    B.
    Plaintiffs contend that their claims sound solely in New
    Jersey’s product-liability law, which required defendants to
    provide adequate warnings of the dangers of prolonged use of
    metoclopramide.   They assert that their state-law claims are not
    private enforcement actions of federal law and that their claims
    promote, rather than frustrate, Congress’s objectives under the
    FDCA.   They note that the responsibility of generic drug
    manufacturers to adhere to the duty of sameness -- to provide
    the same labeling as the brand-name drug -- is relevant only
    because the breach of that duty deprives them of the protection
    of federal preemption.   According to plaintiffs, Mensing shields
    generic drug manufacturers only from state-law claims that seek
    to impose liability for their failure to provide warnings that
    go beyond those approved by the FDA for brand-name drugs.     They
    submit that because federal law required defendants to provide
    the FDA-approved brand-name warnings, state tort law can impose
    liability for inadequate warnings that do not meet the federal
    sameness requirement.
    13
    Plaintiffs maintain that defendants’ duty to provide
    adequate warnings for the generic drug under New Jersey’s
    product-liability law runs parallel to their duty to provide the
    same warnings as the brand-name label.   Indeed, plaintiffs argue
    that state-court lawsuits of this type promote the objectives of
    the FDCA because the FDA cannot properly monitor the adequacy of
    label warnings on the thousands of marketed drugs.   Plaintiffs’
    central premise is that “[d]efendants’ actions would have given
    rise to liability even if the FDCA had never been enacted.”
    Plaintiffs, moreover, posit that defendants’ failure to
    warn of the dangers of the prolonged use of metoclopramide gave
    them “a competitive advantage in the market because their label
    misled doctors, pharmacies and consumers into believing that
    their generic product was safer than the brand[-name drug].”
    III.
    The primary issue in this case is whether federal law
    preempts plaintiffs’ state-law action.   That issue requires that
    we interpret federal law, and therefore our review is de novo.

    IV.
    The doctrine of federal preemption finds its source in the
    Supremacy Clause of the United States Constitution.   The
    Supremacy Clause provides that federal law “shall be the supreme
    Law of the Land,” notwithstanding any state law to the contrary.
    U.S. Const. Art. VI, cl. 2.   A state law that conflicts with a
    federal statute is naturally preempted.   Crosby v. Nat’l Foreign

    (2000)).   When Congress
    legislates in a field where states have traditionally exercised
    their “historic police powers,” the preemption inquiry begins
    with the “assumption” that Congress did not intend to supersede
    a state statute “unless that was [Congress’s] clear and manifest
    purpose.”   Medtronic, Inc. v. Lohr,

    Our task here is to determine whether federal law governing
    the labeling of generic drugs expressly or impliedly preempts a
    state-law product-liability action alleging that defendants
    failed to give adequate warnings explaining the dangers and safe
    use of metoclopramide.   We first turn to the federal scheme
    controlling the approval and labeling of prescription drugs.

    A.
    In accordance with the Federal Food, Drug, and Cosmetic
    Act, 21 U.S.C.A. §§ 301-399f, “a manufacturer seeking federal
    approval to market a new drug must prove that it is safe and
    effective and that the proposed label is accurate and adequate.”

    at 588; see 21 U.S.C.A. §§ 355(b)(1)(A), (d).   Meeting the
    FDA’s approval requirements for a new drug “involves costly and
    lengthy clinical testing.”

    In 1984, Congress passed the Drug Price Competition and
    Patent Term Restoration (Hatch-Waxman) Act of 1981, Pub. L. No.
    98-417, 98 Stat. 1585 (1984).   One of the goals of Hatch-Waxman
    was to make generic drugs more affordable and accessible to the
    17
    public.    FTC v. Actavis, Inc., __ U.S. __, __, 
    133 S. Ct. 2223
    ,
    2228, 
    186 L. Ed. 2d 343
    , 353-54 (2013).    Hatch-Waxman
    streamlined the process for the FDA’s approval of generic drugs.

    at 588-89.    It allows a generic drug manufacturer
    to gain FDA approval of a generic drug simply by showing that it
    is “identical in active ingredients, safety, and efficacy” to a
    brand-name drug (a reference listed drug) already approved by
    the FDA.   
    Mensing, supra
    , 564 U.S. at 612 & 
    n.2, 131 S. Ct. at 2574
    & n.2, 
    180 L. Ed. 2d

    In effect, a generic drug manufacturer is able to piggyback
    on the results of the process that led to FDA approval of both
    the brand-name drug and the brand-name drug’s labeling.     “As a
    result, brand-name and generic drug manufacturers have different
    federal drug labeling duties.”

    drug application, but also when it seeks FDA approval for
    updated labeling to inform the public of previously unknown
    18
    adverse side effects caused by a drug, 21 U.S.C.A. §§ 355(b)(1),
    (d), (j)(2)(A).     On the other hand, a generic drug manufacturer
    is responsible for ensuring only that its labeling “is the same
    as the labeling approved for the [brand-name] drug.”

    589 (alteration in original) (quoting 21 U.S.C.A. §
    355(j)(2)(A)(v)).    Under Hatch-Waxman, a generic drug
    manufacturer cannot deviate from the labeling used by the brand
    name drug -- the warning label must always be the same.      Ibid.;
    see also 21 C.F.R. § 314.150(b)(10).
    Because generic labeling must be the same as that of the
    brand-name drug, “[updated labeling] should be made at the very
    earliest time possible.”     U.S. Dep’t of Health & Hum. Servs.,
    Food & Drug Admin., Ctr. for Drug Evaluation & Research,
    Guidance for Industry: Revising ANDA Labeling Following Revision
    of the RLD Labeling 5 (2000) (emphasis added).     Generic
    manufacturers have been given the means to learn of brand-name-
    labeling updates.     The Office of Generic Drugs in the Office of
    Pharmaceutical Science, Center for Drug Evaluation and Research,
    at the FDA has directed generic manufacturers to “routinely
    monitor the Labeling Review Branch Homepage . . . for
    information on changes in labeling.”     
    Ibid. The Office of
    Generic Drugs “[p]lace[s] monthly updates of approved labeling
    changes” for brand-name drugs with approved generic counterparts

    Ibid. In sum, when
    a brand-name manufacturer strengthens its
    labeling to take into account adverse reactions to a medication,
    federal law requires that the generic drug manufacturer copy the
    brand-name labeling.7   Under the sameness doctrine, a generic

    immediate widespread professional notification,” a “Dear Doctor
    letter” is sent to physicians and other health-care

    substantial new warning information. Ibid.;

    7 After a new drug’s labeling has been approved, a brand-name
    manufacturer may seek prior approval from the FDA to update its
    labeling. 21 C.F.R. § 314.70(b). Alternatively, the brand-name
    manufacturer may file a “Changes Being Effected” (CBE)
    supplement with the FDA, 21 C.F.R. § 314.70(c), to make changes
    to a brand-name drug label to “add or strengthen a
    contraindication, warning, precaution, or adverse reaction” or
    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)(6)(iii)(A), (C). The CBE
    supplement must be submitted to the FDA thirty days before
    distribution, but the CBE process does not require FDA approval
    before changes are made to the label. 21 C.F.R. § 314.70(c).
    Unlike brand-name manufacturers, generic manufacturers are not
    allowed to unilaterally strengthen their labels beyond the
    brand-name warnings through the CBE process.

    generic drug manufacturer may only use the CBE process to
    “change[] its label to match an updated brand-name label or to
    follow the FDA’s instructions.” 
    Ibid. A generic manufacturer
    can update its labeling without pre-approval by the FDA after
    issuing the CBE supplement to the FDA. See 21 C.F.R. §

    drug manufacturer may not unilaterally “strengthen a generic

    B.
    The United States Supreme Court addressed the preemption
    doctrine in the context of federal drug labeling requirements in
    Mensing and Wyeth v. Levine, 
    555 U.S. 555
    , 
    129 S. Ct. 1187
    , 
    173 L. Ed. 2d 51
    (2009).   In 
    Mensing, supra
    , the United States
    Supreme Court held that federal law preempted state-law failure-
    to-warn lawsuits against the defendant generic drug
    manufacturers, which had provided the same labeling as the
    brand-name drug.   564 U.S. at 
    618, 131 S. Ct. at 2577-78
    , 180 L.
    Ed. 2d at 592.   The plaintiffs in that case alleged that, under
    state law, the defendants were required “to use a different,
    stronger label than the label they actually used.”    
    Id. at 617,
    131 S. Ct. at 2577, 
    180 L. Ed. 2d
    at 591.    The generic label
    conformed to the brand-name label.     Id. at 
    610, 131 S. Ct. at 2573
    , 
    180 L. Ed. 2d
    at 587.   The Court concluded that state and
    federal law were in conflict because it was impossible for the
    defendants to comply with both laws.    
    Id. at 618,
    131 S. Ct. at
    21
    2577, 
    180 L. Ed. 2d
    at 592.   Although the plaintiffs contended
    that the generic manufacturers had a state-law “duty to attach a
    safer label to their generic metoclopramide,” federal law
    demanded “that generic drug labels be the same at all times as
    the corresponding brand-name drug labels.”   
    Id. at 618,
    131 S.
    Ct. at 2578, 
    180 L. Ed. 2d
    at 592.   Had the generic
    manufacturers “independently changed their labels to satisfy
    their state-law duty, they would have violated federal law.”
    
    Ibid. The Court therefore
    reasoned that “it was impossible for
    the Manufacturers to comply with both their state-law duty to
    change the label and their federal-law duty to keep the label
    the same.”   
    Ibid. Mensing does not
    directly address the issue before us
    because, here, defendant generic manufacturers of metoclopramide
    tablets did not comply with the FDCA requirement that their
    labeling mimic the brand-name labeling.   The question is whether
    the preemption doctrine is applicable to plaintiffs’ failure-to-
    warn claims when the generic drug manufacturers not only could
    have given stronger warnings, but also were required to do so
    under federal law.
    Wyeth dealt with a scenario that is relevant to our
    inquiry.   There, the United States Supreme Court held that, even
    though the FDA had approved Wyeth’s labeling of a brand-name
    prescription drug, federal law did not preempt a state-law tort
    22
    action against it for giving inadequate warnings about the
    significant risks of administering its drug.    
    Wyeth, supra
    , 555
    U.S. at 563,

    , 
    1204, 173 L. Ed. 2d at 59
    ,
    70.   That result followed because in Wyeth, unlike in Mensing,
    it was not impossible for the brand-name manufacturer to comply
    with both federal law and a state-law duty by modifying the
    drug’s labeling.   
    Id. at 569,
    573, 129 S. Ct. at 1196-97
    , 
    1199, 173 L. Ed. 2d at 62
    , 65.
    The Supreme Court in Wyeth emphasized that the central
    premise of the FDCA and FDA regulations is “that the
    manufacturer bears responsibility for the content of its label
    at all times [and] is charged both with crafting an adequate
    label and with ensuring that its warnings remain adequate as
    long as the drug is on the market.”    
    Id. at 570-71,
    129 S. Ct.
    at 
    1197-98, 173 L. Ed. 2d at 63
    ; see also 21 C.F.R. § 201.80(e)
    (requiring manufacturer to update label “to include a warning as
    soon as there is reasonable evidence of an association of a
    serious hazard with a drug”).   Accordingly, when the risk became
    apparent to Wyeth that its drug might cause gangrene, “Wyeth had
    a duty to provide a warning that adequately described that risk,
    and the [FDCA’s] regulation permitted it to provide such a
    warning before receiving the FDA’s approval.”   
    Id. at 571,

    S. Ct. at 
    1198, 173 L. Ed. 2d at 64
    .   Based on the regulatory
    authorization to issue pre-approval warnings, the Court
    23
    maintained that it was not “impossible for Wyeth to comply with
    both federal and state requirements.”   
    Ibid. The Court also
    concluded that, in passing the FDCA,
    Congress did not intend “to pre-empt common-law tort suits” and
    that such suits serve “as a complementary form of drug
    regulation.”   
    Id. at 578,
    129 S. Ct. at 
    1202, 173 L. Ed. 2d at 68
    .   The Court articulated an overarching federal policy for
    permitting state-law tort suits by stating:
    The FDA has limited resources to monitor the
    11,000 drugs on the market, and manufacturers
    have superior access to information about
    their drugs, especially in the postmarketing
    phase as new risks emerge. State tort suits
    uncover unknown drug hazards and provide
    incentives for drug manufacturers to disclose
    safety risks promptly.    They also serve a
    distinct compensatory function that may
    motivate injured persons to come forward with
    information.    Failure-to-warn actions, in
    particular, lend force to the FDCA’s premise
    that manufacturers, not the FDA, bear primary
    responsibility for their drug labeling at all
    times.
    [Id. at 
    578-79, 129 S. Ct. at 1202
    , 173 L.
    Ed. 2d at 68-69 (footnote omitted).]
    In light of the Supreme Court’s recognition that state tort
    law may serve as a complementary tool in regulating the warnings
    on prescription drugs that have potentially dangerous side
    effects, we next look at this State’s product-liability law.
    C.
    The New Jersey Product Liability Act (PLA), N.J.S.A.
    24
    2A:58C-1 to -11, provides that “[a] manufacturer . . . of a
    product shall be liable in a product liability action only if .
    . . the product causing the harm was not reasonably fit,
    suitable or safe for its intended purpose because it . . .
    failed to contain adequate warnings or instructions.”     N.J.S.A.
    2A:58C-2.   In the case of a prescription drug, the PLA defines
    an adequate warning or instruction as one that a “reasonably
    prudent person” would give and “that communicates adequate
    information on the dangers and safe use of the product . . .
    taking into account the characteristics of, and the ordinary
    knowledge common to, the prescribing physician.”    N.J.S.A.
    2A:58C-4.   The Legislature recognized the important role of the
    federal regulatory system over prescription drugs and provided
    that a warning or instruction approved under the FDCA would
    enjoy “a rebuttable presumption” of adequacy.    See 
    ibid. The PLA is
    an expression of New Jersey’s strong public
    policy of ensuring that manufacturers attach adequate warnings
    and instructions to prescription drugs so that consumers,
    ultimately, will be made aware of the relevant risks, dangers,
    and precautions in taking such medications.     Cf. Gantes v. Kason
    Corp., 
    145 N.J. 478
    , 490 (1996) (“[T]his State has a strong
    interest in encouraging the manufacture and distribution of safe
    products for the public and, conversely, in deterring the
    manufacture and distribution of unsafe products within the
    25
    state.”).   The Legislature understood, in the case of
    prescription drugs, that the PLA must coexist with a federal
    scheme that highly regulates the marketing of such drugs.       See
    
    Cornett, supra
    , 211 N.J. at 387.     The PLA is a codification of
    tort-law principles, where the state has traditionally exercised
    its historic police powers.   See 
    Medtronic, supra
    , 518 U.S. at
    
    485, 116 S. Ct. at 2250
    , 135 L. Ed. 2d at 715.     As such, a
    failure-to-warn claim under the PLA is not preempted unless
    Congress has expressed its “clear and manifest purpose” to do
    so.   Ibid. (quoting 
    Rice, supra
    , 331 U.S. at 
    230, 67 S. Ct. at 1152
    , 91 L. Ed. at 1459)).
    VI.
    A.
    Plaintiffs’ state-law failure-to-warn claims against
    defendant generic drug manufacturers are not barred by Mensing
    and are permissible under Wyeth.
    The defendant generic manufacturers of metoclopramide in
    Mensing did precisely what the FDCA demanded -- they provided
    the same labeling that appeared with the brand name.     See
    
    Mensing, supra
    , 564 U.S. at 609-10, 
    618, 131 S. Ct. at 2572-73
    ,
    2577-78, 
    180 L. Ed. 2d
    at 587, 592.     Under Hatch-Waxman, generic
    manufacturers do not have to replicate the costly and lengthy
    clinical drug testing and research by brand-name manufacturers.
    See id. at 
    612, 131 S. Ct. at 2574
    , 
    180 L. Ed. 2d
    at 588-89.        In
    26
    turn, the FDCA also permits the generic manufacturer to rely on
    the brand-name labeling and forbids them from issuing better or
    stronger warnings.   See 
    id. at 614-15,
    131 S. Ct. at 2575-76,
    
    180 L. Ed. 2d
    at 588-89.    Federal law preempted the state-law
    claims in Mensing because those claims were premised on a duty
    of generic manufacturers to give “safer” warnings than the FDA-
    approved brand-name warnings for metoclopramide.    
    Id. at 618,
    131 S. Ct. at 2578, 
    180 L. Ed. 2d
    at 592.     What state law
    permitted was impossible under federal law.    
    Ibid. The case before
    us is not like Mensing.     Here, defendant
    generic manufacturers of metoclopramide tablets did not conform
    their labeling to that of the brand-name drug and therefore were
    in violation of the FDCA’s sameness requirement.    Had defendants
    complied with federal law, they would be entitled to the safe-
    harbor protection afforded by Mensing.    See 
    id. at 613,
    131 S.
    Ct. at 2574-75, 
    180 L. Ed. 2d
    at 589.    No law prevented
    defendants from giving the same warnings that appeared on the
    labeling of the brand-name drug -- the warnings that plaintiffs
    contend the PLA required.   Defendants did not have to violate
    federal law to comply with state law.    Unlike Mensing, here it
    was not impossible to comply with both federal and state law.
    As a result of the discrepancy between the brand-name and
    generic labeling of metoclopramide tablets, consumers of Reglan
    tablets were informed that “[t]herapy should not exceed 12 weeks
    27
    in duration,” whereas the plaintiff generic consumers were
    informed only that “[t]herapy longer than 12 weeks has not been
    evaluated and cannot be recommended.”8   Based on the inadequacy
    of the generic warnings, plaintiffs allege that they used
    metoclopramide beyond the prescribed period and therefore
    developed tardive dyskinesia, a serious neurological disorder.
    Under 
    Wyeth, supra
    , plaintiffs’ state-law claims are not at
    odds with the FDCA, but are “a complementary form of drug
    regulation.”   555 U.S. at 
    578, 129 S. Ct. at 1202
    , 173 L. Ed. 2d
    at 68.   In keeping with Wyeth, each defendant generic drug
    “manufacturer bears responsibility for the content of its label
    at all times,” and each “had a duty to provide a warning that
    adequately described that risk, and the [FDCA’s] regulation
    permitted it to provide such a warning.”   See id. at 
    570-71, 129 S. Ct. at 1197-98
    , 173 L. Ed. 2d at 63-65.
    This case drives home the point made in Wyeth that the FDA
    does not have the resources to monitor the labeling of thousands
    of drugs after they are marketed, and to the extent that
    “[s]tate tort suits uncover unknown drug hazards[, they] provide
    incentives for drug manufacturers to disclose safety risks
    promptly.”   See id. at 
    578-79, 129 S. Ct. at 1202
    , 
    173 L. Ed. 2d 8
    While the drug labels are initially disseminated to doctors and
    pharmacists, they, in turn, inform their patients, passing the
    warnings on to consumers. See Niemiera v. Schneider, 
    114 N.J. 550
    , 559 (1989).
    28
    at 68-69.   Thus, state law promotes rather than “stands as an
    obstacle to the accomplishment and execution of the full
    purposes and objectives of Congress” in passing the FDCA.       See
    
    Gade, supra
    , 505 U.S. at 
    98, 112 S. Ct. at 2383
    , 120 L. Ed. 2d
    at 84 (first quoting 
    Hines, supra
    , 312 U.S. at 
    67, 61 S. Ct. at 404
    , 85 L. Ed. at 587; and then citing 
    Felder, supra
    , 487 U.S.
    at 138, 
    108 S. Ct. 2302
    , 
    101 L. Ed. 2d 123
    ; 
    Perez, supra
    , 402
    U.S. at 649, 
    91 S. Ct. 1704
    , 
    29 L. Ed. 2d 233
    ).    Here,
    plaintiffs’ state-law failure-to-warn claims shined a light on
    the inadequacy of warnings of a drug, which if used for a
    prolonged period could cause grave harm.    The PLA provides a
    remedy to plaintiffs, if they can prove their claims to a jury,
    and the pursuit of those claims is not barred by federal law.
    B.
    Importantly, plaintiffs’ state-law claims run parallel to,
    but are not dependent on, federal law.     Plaintiffs could proceed
    on their failure-to-warn claims under the PLA even if the FDCA
    and Hatch-Waxman did not exist.    From that perspective, the
    present case is not comparable to Buckman Co. v. Plaintiffs’
    Legal Committee, 
    531 U.S. 341
    , 
    121 S. Ct. 1012
    , 
    148 L. Ed. 2d 854
    (2001), on which defendants rely.
    In Buckman, the United States Supreme Court held that the
    Medical Device Amendments to the FDCA preempted a state-law tort
    action premised on a claim that the defendant medical-device
    29
    manufacturer committed a fraud on the FDA.      
    Id. at 348,
    121 S.
    Ct. at 
    1017, 148 L. Ed. 2d at 861
    .      In that case, the defendant
    allegedly made fraudulent representations to the FDA to secure
    approval for the marketing of defective orthopedic bone screws
    that directly caused injuries to a class of plaintiffs.      
    Id. at 343,
    121 S. Ct. at 
    1015, 148 L. Ed. 2d at 858
    .     Preemption
    applied because “the federal statutory scheme amply empower[ed]
    the FDA to punish and deter fraud against the Agency,” by
    referring criminal charges, seizing the device, and seeking
    civil penalties and injunctive relief.      
    Id. at 348-49,
    121 S.
    Ct. at 
    1017-18, 148 L. Ed. 2d at 861-62
    .      The Court concluded
    that the fraud-on-the-agency claim was not based on traditional
    state tort law because a “critical element” of those claims was
    dependent on the Medical Device Amendments.      
    Id. at 353,
    121 S.
    Ct. at 
    1020, 148 L. Ed. 2d at 864
    .
    The Court pointedly distinguished Buckman from Medtronic.
    In Medtronic, preemption did not apply to state-law negligence
    claims against a manufacturer for allegedly producing defective
    pacemakers because those claims did not arise “solely from the
    violation of FDCA requirements.”      
    Id. at 352-53,
    121 S. Ct. at
    
    1019-20, 148 L. Ed. 2d at 864
    .   The Supreme Court in Buckman
    indicated that “Medtronic can be read to allow certain state-law
    causes of actions that parallel federal safety requirements,”
    ibid., which is precisely what the Court later held in 
    Wyeth, 30 supra
    , 555 U.S. at 
    581, 129 S. Ct. at 1204
    , 173 L. Ed. 2d at 70,
    and what we hold today.     The present case is different from
    Buckman because, here, the “critical element” to plaintiffs’
    claims is not defendants’ violation of the FDCA, but defendants’
    failure to give adequate warnings about the prolonged use of
    metoclopramide.
    Defendants’ reliance on Cornett is also misplaced.        In
    
    Cornett, supra
    , we came to the unremarkable conclusion that,
    under the Medical Device Amendments, federal law preempted
    state-law tort actions against the defendants premised on a
    fraud on the 
    FDA. 211 N.J. at 389
    .   That result was commanded
    by Buckman.    
    Ibid. We made clear,
    however, that a failure-to-
    warn claim alleging that the defendants withheld information
    from or made misrepresentations to the general public and the
    medical community about the safe use of the medical device at
    issue fell “within a traditional area of state concern and
    regulation.”   
    Id. at 390.
        That claim could proceed under the
    Product Liability Act “because fraud on the FDA is not an
    element of the claim.”      
    Ibid. Accordingly, allowing the
    failure-to-warn claims in the
    present case to proceed is compatible with the preemption
    principles articulated in both Buckman and Cornett.
    C.
    Our conclusion that plaintiffs’ state-law failure-to-warn
    31
    claims are not preempted by federal law is supported by Fulgenzi
    v. PLIVA, Inc., 
    711 F.3d 578
    (6th Cir. 2013), and case law in
    other jurisdictions.   In Fulgenzi, like here, PLIVA, a generic
    manufacturer of metoclopramide, failed to update its labeling to
    conform to the 2004 FDA-approved brand-name-labeling change.
    
    Id. at 580.
      As a result of the inadequate labeling, the
    plaintiff alleged that she prolonged her use of metoclopramide,
    which led to her developing tardive dyskinesia.   
    Ibid. The plaintiff filed
    a product-liability failure-to-warn suit under
    Ohio law, seeking damages.   
    Id. at 581-82.
      The United States
    Court of Appeals for the Sixth Circuit determined that federal
    preemption did not bar the state claims.   
    Id. at 580.
       After
    reviewing Mensing, Wyeth, and Buckman, the Sixth Circuit
    concluded that state laws providing damages for inadequate
    warnings -- warnings that did not comply with the federal duty
    of sameness -- did not conflict with the FDCA or Hatch-Waxman.
    
    Id. at 585-86.
    The federal appeals court maintained that the plaintiff’s
    suit was not “premised on [a] violation of federal law, but
    rather on an independent state duty” and that “[t]he federal
    duty of sameness [was] not ‘a critical element’ in [the
    plaintiff’s] case.”    
    Id. at 587
    (quoting 
    Buckman, supra
    , 531
    U.S. at 353, 121 S. Ct. at 
    1020, 148 L. Ed. 2d at 864
    ).     It
    reasoned that the adequacy of PLIVA’s warnings was not relevant
    32
    to its duty under federal law and that “[a] jury need not know
    about the duty of sameness at all to determine whether the
    warning label used by PLIVA in 2004 and 2006 was inadequate, and
    whether the failure to include the updated warning was a
    proximate cause of [the plaintiff’s] injuries.”   
    Ibid. Last, Fulgenzi noted
    that, at trial, “[t]o avoid Mensing preemption,
    [the plaintiff] must use the language of the 2004 FDA-approved
    label in her proximate-cause argument, not (or not merely) the
    fact of the failure to update.”    
    Id. at 588.9
    A number of federal and state courts, like the Sixth
    Circuit in Fulgenzi, have found that federal law does not
    preempt state-law claims arising from the failure of generic
    drug manufacturers to update labeling to conform to that of the
    brand name.   See, e.g., In re Fosamax Prods. Liab. Litig., 
    965 F. Supp. 2d 413
    , 417 (S.D.N.Y. 2013); Phelps v. Wyeth, Inc., 
    938 F. Supp. 2d 1055
    , 1063-66 (D. Or. 2013); Teva Pharms. USA, Inc.

    158 Cal. Rptr. 3d 150
    , 156-61 (Ct. App.),

    135 S. Ct. 1699
    , 
    191 L. Ed. 2d 695
    (2015); Franzman v.
    9 Fulgenzi also acknowledged that at trial “[f]ederal standards
    are also likely to arise in determining the adequacy of PLIVA’s
    warning, since FDA approval and industry practices may be
    relevant to the state duty of care.” 
    Id. at 588-89.
    33
    Wyeth, Inc., 
    451 S.W.3d 676
    , 679 (Mo. Ct. App. 2014).
    In contrast, Morris v. PLIVA, Inc., 
    713 F.3d 774
    , 777 (5th
    Cir. 2013) (per curiam), found that Mensing preempts failure-to-
    warn claims against generic manufacturers who have not updated
    their warnings.   There, the United States Court of Appeals for
    the Fifth Circuit held that a state-law claim against the
    generic manufacturer PLIVA for its failure to adopt the 2004
    FDA-approved brand-name-warning label for metoclopramide was “a
    claim that PLIVA breached a federal labeling obligation [that]
    sounds exclusively in federal (not state) law, and is
    preempted.”   
    Ibid. (citing 21 U.S.C.A.
    § 337(a); 
    Buckman, supra
    ,
    531 U.S. at 349 
    n.4, 121 S. Ct. at 1018
    n.4, 148 L. Ed. 2d at
    862 
    n.4).   The Fifth Circuit, however, did not give any detailed
    analysis or reasoning for that conclusion.10
    We do not find Morris persuasive.   Instead, we join those
    courts, such as the Sixth Circuit in Fulgenzi, that have
    concluded that federal preemption does not apply to failure-to-
    warn claims, such as those in the present case.   We reject the
    notion that a plaintiff can proceed with a state-law failure-to-
    warn claim against a brand-name drug manufacturer that used FDA-
    approved warnings, as was true in Wyeth, but not against a
    10Without citing any authority, the Morris court asserted that
    “[t]ort liability does not arise for failure to attach an
    inadequate label.” See 
    Morris, supra
    , 713 F.3d at 777. The
    labeling cases cited in this opinion indicate otherwise.
    34
    generic manufacturer that provides warnings that do not even
    match the FDA-approved brand-name labeling.   Congress could not
    have intended such an absurd result.
    VII.
    Here, plaintiffs claim that the generic drug manufacturers’
    inadequate warnings of the dangers of the prolonged use of
    metoclopramide proximately caused neurological disorders, such
    as tardive dyskinesia.   In 2004, with FDA approval, brand-name
    manufacturers updated their labeling to indicate that the use of
    metoclopramide “should not exceed 12 weeks in duration.”
    Although generic drug labeling is required to be the same as
    that of the brand name under federal law, defendant generic
    manufacturers, apparently, did not update their labeling “at the
    very earliest time possible” in accordance with the directive of
    the U.S. Department of Health and Human Services, Food and Drug
    Administration, Center for Drug Evaluation and Research.
    Guidance for Industry: Revising ANDA Labeling Following Revision
    of the RLD Labeling 5 (2000).   The FDA’s Office of Generic Drugs
    had directed generic manufacturers to “routinely monitor [its]
    Labeling Review Branch Homepage” for labeling updates that were
    made monthly on the Homepage.   
    Ibid. Generic manufacturers were
    also advised that information about brand-name labeling changes
    was available from the FDA’s Freedom of Information Staff.     See
    
    ibid. 35 Some lag
    time is inevitable before a generic drug
    manufacturer can conform to the FDA’s sameness requirement.        For
    example, the updates on the FDA website appear monthly.      See
    
    ibid. Needless to say,
    if a generic drug manufacturer is
    seeking safe-harbor protection under the sameness doctrine, then
    it must exercise reasonable diligence to learn of updates to the
    brand-name labeling.   If the trial court determines that any
    defendant updated its labeling “at the very earliest time
    possible,” ibid., the state law claim would be preempted.
    Whether preemption applies is a matter of law to be decided by
    the court, not a jury.   See 
    Fulgenzi, supra
    , 711 F.3d at 583.
    Despite the easy access to information about brand-name
    labeling changes and the time-sensitive need to make those
    changes, defendant generic manufacturers delayed updating their
    labeling -- defendant Actavis-Elizabeth for six months,
    defendant Teva Pharmaceuticals for one year, defendants Mutual
    Pharmaceutical Company and United Research Laboratories for one-
    and-one-half years.    Defendant PLIVA did not update its labeling
    for the four-and-one-half years that it continued to manufacture
    metoclopramide through 2008.   Watson Laboratories did not
    include the 2009 FDA-approved black-box warning in its
    metoclopramide shipments until more than ten months after
    receiving notice of the labeling change.
    A violation of the FDCA’s sameness requirements is not an
    36
    element of plaintiffs’ claims.     Plaintiffs’ claims do not “exist
    solely by virtue of” a federal regulatory scheme.     See 
    Buckman, supra
    , 531 U.S. at 353, 121 S. Ct. at 
    1020, 148 L. Ed. 2d at 864
    .    Their state-law cause of action is not a disguised means
    of enforcing a federal law or regulation.     Rather, plaintiffs
    are availing themselves of protections long available under this
    State’s product-liability law.     States have traditionally
    exercised their powers to promote the health and welfare of
    their citizens by regulating the safety of products through
    state tort law.   Plaintiffs’ claims run parallel to the FDCA’s
    sameness requirement for labeling warnings, but they are not
    based on that requirement.    To be sure, to avoid a clash with
    Mensing and Hatch-Waxman, plaintiffs may not contend that
    defendant generic manufacturers had a duty to provide warnings
    beyond those that the FDA approved for the brand name.
    Under state law, plaintiffs must prove the inadequacy of
    defendants’ labeling of metoclopramide.      This State’s product-
    liability law requires defendant generic manufacturers to
    “communicate[] adequate information on the dangers and safe use
    of [metoclopramide], taking into account . . . knowledge common
    to[] [a] prescribing physician.”      See N.J.S.A. 2A:58C-4.
    Plaintiffs therefore must demonstrate that a reasonably prudent
    generic manufacturer of metoclopramide tablets after July 2004
    would have provided a stronger warning than the 1985 warning:
    37
    “Therapy longer than 12 weeks has not been evaluated and cannot
    be recommended.”     In short, plaintiffs must show that defendant
    generic drug manufacturers had a duty to give a stronger warning
    than the one provided and that the failure to do so proximately
    caused their injuries.    See 
    Fulgenzi, supra
    , 711 F.3d at 588.
    Our charge here is merely to determine whether federal law
    preempts plaintiffs’ claims.    We conclude that federal law does
    not.    Whether plaintiffs can prove that defendants breached
    their state-law duty to provide adequate warnings and, if so,
    whether the breach of that duty proximately caused plaintiffs’
    injuries is a matter for another day.
    VIII.
    For the reasons expressed, plaintiffs’ state-law failure-
    to-warn claims based on the alleged inadequate labeling of
    metoclopramide -- labeling that did not mimic the brand-name
    labeling -- are not preempted by federal law.    We therefore
    affirm the judgment of the Appellate Division, which upheld the
    trial court’s denial of defendants’ motions to dismiss those
    claims.   We remand to the trial court for proceedings consistent
    with this opinion.
