delivered the opinion of the Court.
In 2004, thе 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 metoclo-pramide 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,

S.Ct.
at 2574,
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under Mensing, a state-law failure-to-warn claim is preempted when a generic drug manufacturer gives warnings that are outdated and inferior to the manufacturer’s brand-name warnings approved by the FDA.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 *320 for summary judgment, finding that federal preemption did not apply because defendant had a duty under state law to providе 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’ 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 Mens-ing, 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.
I.
A.
This case began with the filing of nearly 1000 individual lawsuits against over fifty brand-name and generic manufacturers of meto-clopramide. 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— *321 PLIVA Inc., Barr Pharmaceuticals, LLC, Barr Laboratories, Inc., Watson Laboratories, Inc., Aetavis-Elizabeth LLC, Teva Pharmaceuticals USA, Inc., Mutual Pharmaceutical Company, Inc., and United Research Laboratories, Inc. — are generic drug manufacturers of metoclopramide tablets that did not сhange 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 of symptoms associated with acute and recurrent diabetic gastroparesis. 3 It is “designed to speed the movement of food through the digestive system.” Mensing, supra, 564 U.S. at 609, 131 S.Ct. at 2572, 180 L.Ed.2 d at 586.
The history of FDA approvals for labeling changes and the 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 apрroval from the FDA to market metoclo-
*322
pramide tablets.
Id.
at 609, 131
S.Ct.
at 2572,
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 “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.’ ”
Mensing, supra,

U.S.
at 610, 131
S.Ct.
at 2573,
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-appi’oved 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 *323 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 metoclo-pramide 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 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 metoclоpramide tablets, they took the drug beyond its prescribed period, causing them to develop tardive dyskinesia or other movement disorders.

The trial court denied defendants’ various motions to dismiss plaintiffs’ failure-to-warn claims on federal-preemption *324 grounds. 5 The court maintained that federal law required defendant generic manufacturers of mеtoclopramide 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 manufacturers of metoclo-pramide 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 thе 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.
*325 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 dangers of prolonged metoclopram-ide use would not frustrate federal law. It concluded that preemption did not apply in this ease because it was possible for the generic drug manufacturers to comply with both state and federal law. Last, the panel rejected the argument that

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 involv *326 ing generic drugs.” They argue that the source of 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. §§ 301-399Í. They claim that, under 21 U.S.C.A. § 337, the federal government, not a private party, is authorized to initiate a suit for noneompliance 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, “[permitting 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 end run around federal preemption. They maintain that the FDA, not a jury impaneled in a state court, is in the best position tо 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 metoclopram-ide. They assert that their state-law claims are not private *327 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.
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 “[djefendants’ actions would have given rise to liability even if the FDCA had never been enaсted.”
Plaintiffs, moreover, posit that defendants’ failure to warn of the dangers of the prolonged use of metoelopramide 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.

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 “on the Labeling Review Branch Homepage.” 6 Ibid. “All approved labeling for [brand-name drugs] is [also] available from Freedom of Information Staff’ at the FDA.

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.

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,
Mensing does not directly address the issue before us because, here, defеndant generic manufacturers of metoelopramide 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 action against it for giving inadequate warnings about the significant risks of administering its drug. Wyeth, supra, 555 U.S. at 563, 581, 129 S.Ct. at 1193, 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 resрonsibility 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”). *334 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, 129 S.Ct. at 1198, 173 L.Ed.2d at 64. Based on the regulatory authorization to issue pre-approval warnings, the Court 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,
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-wam actions, in particular, lend force to the FDCA’s premise that manufacturers, not the FDA, bear primary responsibility for then’ 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 dаngerous side effects, we next look at this State’s product-liability law.
C.
The New Jersey Product Liability Act (PLA), N.J.S.A. 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 eommu- *335 nicates 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 rеbuttable 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.

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

did precisely what the FDCA demanded — they provided the
same
labeling that appeared with the brand name.

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 bе entitled to the safe-harbor protection afforded by
Mensing. See id.
at 613, 131
S.Ct.
at 2574-75,
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 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 inadequa- *337 ey of the generic warnings, plaintiffs allege that they used meto-clopramide beyond the prescribed period and therefore develоped 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

This case drives home the point made in

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 *338 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

The Court pointedly distinguished

*339
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,
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 claims are not preempted by federal law is supported by
Fulgenzi v. PLIVA, Inc.,
*340
The federal appeals court maintained that the plaintiffs 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 plaintiffs] case.”
Id.
at 587 (quoting
Buckman, supra,
531
U.S.
at 353, 121
S.Ct.
at 1020,
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.,
In contrast,
Morris v. PLIVA, Inc.,
We do not find Morris persuasive. Instead, we join those courts, such as the Sixth Circuit in Fulgenzi, that have concluded that federal preеmption does not apply to failure-to-warn claims, such as those in the present ease. 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 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 оf the brand name under federal law, defendant generic manufacturers, apparently, did not update their labeling “at the very earliest *342 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.
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 appеar 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,
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 metoelopram-ide 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.
*343
A violation of the FDCA’s sameness requirements is not an 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,
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 [metoelo-pramide], 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: “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,
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 *344 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-wam claims based on the alleged inadequate labeling of metoelopram-ide — 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 оf defendants’ motions to dismiss those claims. We remand to the trial court for proceedings consistent with this opinion.

Plaintiffs allege that defendants failed to comply with a 2009 FDA-approved black-box warning for metoclopramide, but that claim appears to apply only to defendant Watson Laboratories.
Diabetic gastroparesis is a condition in which emptying of food from the stomach is delayed. Taber's Cyclopedic Medical Dictionary 999 (22d ed.2013). This may cause bloating, abdominal pain, nausea, or vomiting and lead to the worsening of gastroesophagеal reflux. Gastroparesis, Nat’l Inst, of Diabetes & Digestive & Kidney Diseases, U.S. Dep’t of Health & Hum. Servs., https://www. niddk.nih.gov/health-information/health-topics/digestive-diseases/gastroparesis/ Pages/facts.aspx.
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.
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,”

When a labeling revision for a brand-name drug “warrants immediate widespread professional notification,” a “Dear Doctor letter" is sent to physicians and other health-care professionals by a drug manufacturer or the FDA advising of substantial new warning information. Ibid.; Mensing, supra, 564 U.S. at 615, 131 S.Ct. at 2576, 180 L.Ed.2d at 590; see 21 C.F.R. § 200.5.
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 beforе distribution, but the CBE process does not require FDA approval before changes are made to the label. 21 C.F.R. § 314.70(c).
*332
Unlike brand-name manufacturers, generic manufacturers are not allowed to unilaterally strengthen their labels beyond the brand-name warnings through the CBE process.

While the drug labels are initially disseminated to doctors and pharmacists, they, in turn, inform their patients, passing the warnings on to consumers.

Fulgenzi also acknowledged that at trial "[federal 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.
Without citing any authority, the

court asserted that "[t]ort liability does not arise for failure to attach an inadequate label.”
