Pfizer Sued: Depo-Provera Allegedly Causing Brain Tumors

Publish Date : 11/07/2024

A new lawsuit claims Pfizer Inc. did not warn patients about the risk of brain tumors linked to its injectable contraceptive, Depo-Provera. The complaint alleges Pfizer failed to investigate and disclose the risk of developing intracranial meningiomas—a type of brain tumor—linked to Depo-Provera and similar progesterone-based drugs.

Plaintiff seek damages, claiming failure-to-warn, defective design, negligence, and misrepresentation.

Plaintiffs point out that, unlike the U.S., the EU and UK labels now warn of the increased risk of intracranial meningiomas. A 2024 study in the British Medical Journal links prolonged use of medroxyprogesterone acetate medications, like Depo-Provera, to a higher risk of developing this type of brain tumor.
