A federal decide in California filed an essential OTC preemption choice earlier this month, and it’s essential as a result of it utilized federal preemption to close down (for now) one of many many current benzene-related shopper class actions. The case is Daugherty v. Padagis US LLC, No. 24-cv-02066, 2025 WL 2243622 (N.D. Cal. Aug. 6, 2025), and the merchandise at situation are OTC benzoyl peroxide zits remedies.
Pre-pubescents and gangly teenagers have been rubbing benzoyl peroxide lotions on their faces to deal with blemishes for the reason that early Sixties, which we’d name a fairly good pattern dimension. So what’s their beef now? Nicely, it appears our pals on the “impartial” lab Valisure bought their palms on numerous benzoyl peroxide merchandise and purportedly discovered that they “comprise or systematically degrade” into benzene. If the plaintiffs in Daughtery had identified, they allegedly would have paid much less for the merchandise or wouldn’t have bought them in any respect. So give them their a refund.
We now have seen this play earlier than. Furthermore, as we reported right here, the FDA examined “95 zits merchandise containing benzoyl peroxide for attainable benzene contamination,” and “greater than 90% of examined merchandise had undetectable or extraordinarily low ranges of benzene.” FDA, Assertion ¶1 (March 11, 2025).
The plaintiffs in Daugherty sued anyway, and their lawsuit, like others, ran aground on federal preemption. They’d standing to sue, based mostly on their allegation that they skilled some financial hurt, i.e., damage in actual fact. However with regard to OTC merchandise, the FDCA expressly prohibits states from establishing “any requirement” that “is completely different from or along with, or that’s in any other case not equivalent with” federal necessities. That’s categorical preemption, and the FDA’s Zits Monograph expressly permits using benzoyl peroxide as an energetic ingredient and imposes particular labeling and warning necessities. Daugherty, at *3.
To the extent the plaintiffs had been in search of something completely different, together with completely different warnings about benzene, the FDCA expressly preempted their claims. Because the district courtroom held, “This Court docket joins its sister courts in holding that the FDCA preempts Plaintiffs’ state regulation claims which problem the omission of warnings on BPO merchandise which can be completely different from and never required by the FDCA . . . .” Id. at *8.
Many states, nonetheless, incorporate federal necessities—comparable to federal present Good Manufacturing Practices (“cGMP”) and federal adulteration requirements—into state regulation, which allowed plaintiffs to say that they had been imposing state necessities that echoed federal necessities. In different phrases, federal regulation didn’t expressly preempt their claims as a result of they weren’t “completely different from or along with” federal necessities. They had been the identical.
The district courtroom, nonetheless, was inclined to search out these “parallel” claims impliedly preempted, too. First, the plaintiffs’ state regulation claims appeared to require substantial interpretation of the FDCA and federal necessities. Good Manufacturing Practices, for instance, usually name for “applicable” determinations, or “passable” conformance to specs, or “thorough investigation” of nonconforming merchandise. Permitting courts from across the nation to interpret these provisions would (1) create an impediment to the federal goal of nationwide uniformity in OTC drug high quality requirements and (2) intrude on Congress’s delegation of unique enforcement of the FDCA to the FDA. If the plaintiffs’ allegations required interpretation of federal necessities, implied preemption would apply.
Second, the plaintiff didn’t plead that the state legal guidelines they cited imposed necessities which can be “parallel” to federal necessities. The plaintiffs supplied a “laundry record” of state statutes, however didn’t set up “that these state rules really impose necessities equivalent to federal ones.” Daugherty at *12. The plaintiffs alleged purported violations of cGMP, however they weren’t particular and didn’t elaborate. They mainly alleged that the defendants should have violated cGMP as a result of they allegedly allowed benzene-contaminated merchandise to achieve customers, type of a res ipsa loquitur idea. That, nonetheless, was not sufficient as a result of “Plaintiffs don’t assert how Defendants violated or deviated from particular cGMP requirements and how such deviations led to the adulteration of [their] BPO merchandise.” Id. As well as, to the extent the plaintiffs had been alleging an omission-based idea of shopper fraud, their non-specific allegations failed to satisfy the usual underneath Rule 9(b).
The courtroom due to this fact was inclined to dismiss the plaintiffs’ claims, however allowed them go away to amend to allege, with specificity, the parallel state legal guidelines they’re asserting and particular info establishing that the defendants violated explicit cGMPs. Furthermore, to keep away from implied preemption, the asserted violations should be “restricted to these which could be confirmed with out interpretation” of federal necessities, which is a tall order. Id. at *13. The courtroom could possibly be throwing the plaintiffs a lifeline right here, or it could possibly be permitting them a chance to enhance the report earlier than it lowers the growth. Given the courtroom’s reasoning and its acknowledged “inclination” to dismiss the case, we hope and count on the latter.
