Depo-Provera is a long-acting injectable contraceptive used by millions of women in the United States. In March 2024, the British Medical Journal published a major study finding that women who used Depo-Provera (medroxyprogesterone acetate) for one year or longer faced a significantly elevated risk of developing intracranial meningioma — a tumor in the lining of the brain. Pfizer warned patients in Canada, the U.K., and the European Union about this risk. U.S. patients were never given the same warning. Lawsuits are now being filed across the country.
New scientific evidence, inconsistent international warnings, and the serious medical consequences of meningioma have driven a rapidly growing wave of claims against Pfizer.
A large French study published in The BMJ in March 2024 documented a strong dose-response relationship between Depo-Provera use and intracranial meningioma. The longer a patient used the injection, the higher her risk — a finding that confirmed and expanded on earlier research connecting progestin-based hormonal therapies to meningioma development.
The same drug, sold by the same manufacturer (Pfizer), has carried explicit meningioma warnings in Canadian, U.K., and European Union prescribing information for years. Until late 2024, U.S. labels did not. Plaintiffs allege this constitutes a clear failure to warn under U.S. product liability law.
Even when benign, meningiomas often require brain surgery, radiation, anti-seizure medication, and long-term monitoring. Many survivors are left with cognitive, visual, hearing, or neurological impairments — and significant medical debt.
Plaintiffs' attorneys are coordinating cases nationwide, and a federal multidistrict litigation is being organized. Filing deadlines vary by state — and because meningioma can take years to develop after exposure, prompt action helps protect your right to file.

We work with firms already filing in the Depo-Provera mass tort — attorneys who understand failure-to-warn doctrine, hormonal contraception science, and Pfizer's defense playbook.
A brain tumor diagnosis is overwhelming. Our intake team listens carefully — to your medical history, treatment, and the impact of meningioma on your life.
Depo-Provera claims are handled on contingency. You pay no upfront costs and no attorney fees unless your case results in a settlement or verdict.
Settlements pay for surgery, radiation, ongoing care, and the wage loss meningioma often causes. We're focused on holding Pfizer to the same standard it already meets in other countries.
It takes less than two minutes. There's no obligation. If your case qualifies, we'll connect you directly with an attorney handling Depo-Provera claims.
