Depo-Provera Lawsuit Alleges Shot Causes Brain Tumors

Publish Date : 11/01/2024

Depo-Provera lawsuits allege the contraceptive shot, which contains medroxyprogesterone acetate, may increase the risk of developing meningiomas, a type of brain tumor. Plaintiffs claim Pfizer, the manufacturer, failed to adequately warn users of this risk. Litigation is in its early stages, with no settlements or verdicts yet.
A March 2024 study published in The BMJ found a 5.6-fold increased risk of meningioma among women using Depo-Provera compared to other birth control methods, particularly with long-term use. To qualify for these lawsuits, claimants must have used Depo-Provera or its generic at least twice and have a meningioma diagnosis. Pfizer has acknowledged the potential risk and is updating its product labels accordingly.
