Last week, the Eighth Circuit put the final seal on Pliva’s victory in Brinkley v. Pfizer, Inc., 2014 U.S. App. LEXIS 22742 (8th Cir. Dec. 2., 2014), upholding the district court’s dismissal with prejudice under Mensing and Bartlett. The case involved a doctor who prescribed Reglan and a pharmacist who, when filling the prescription, switched it out for Pliva’s generic metoclopramide. Id. at *2. While the Reglan label had been changed in 2004 to add a warning on long-term use, Pliva, plaintiff claimed, failed to make the corresponding update to its label. So she pursued a failure to update claim.
In some sense, that’s a good starting point. By styling her failure to warn claim as a “failure to update,” Plaintiff was conceding that she could not bring a standard failure to warn claim.” Generic manufacturers can only change their label to match a corresponding change in the branded label, and plaintiff hoped that her “failure to update” claim would avoid Mensing preemption.
But this claim had problems too, and they centered on the learned intermediary doctrine. Pliva’s duty to warn, if any, ran to plaintiff’s prescribing doctor. But, as plaintiff alleged, her doctor prescribed Reglan, not Pliva’s generic metoclopramide. Consistent with that, the doctor consulted the Reglan label, not the Pliva label. Id. at 2-3. In short, the doctor never read Pliva’s label. So no matter what Pliva put there, it could not have affected the doctor’s decision to prescribe the drug to plaintiff. We lawyers call that a failure of proximate causation.Continue Reading Learned Intermediary Doctrine Gets an Assist in Preempting a Failure to Update Claim
