Did Depo-Provera Cause Your Brain Tumor?
Women diagnosed with meningioma after long-term use of Depo-Provera may have a legal claim for compensation. A landmark 2024 BMJ study found a dramatically elevated risk, the FDA approved a meningioma warning label update in December 2025, and thousands of cases are now consolidated in federal MDL 3140 with Daubert hearings set for June 2026 and first trials scheduled for December 2026.
Depo-Provera & Meningioma: What You Need to Know
Depo-Provera (medroxyprogesterone acetate, or MPA) is an injectable contraceptive manufactured by Pfizer that has been used by millions of women in the United States. Administered as a shot every three months, it has been prescribed since the early 1990s.
In March 2024, a peer-reviewed study in the British Medical Journal (Dray et al.) analyzed health data from over 18,000 women in France and found that long-term use of Depo-Provera was associated with a 5.6 times higher risk of intracranial meningioma requiring surgery compared to non-users.
A meningioma is a tumor of the membranes surrounding the brain and spinal cord. While often classified as benign, these tumors can grow to press on the brain - causing headaches, vision loss, hearing problems, cognitive changes, and seizures - and often require surgery, radiation, or both.
Lawsuits allege that Pfizer knew or should have known about this association and failed to adequately warn patients and prescribing physicians, depriving women of the ability to make informed contraceptive choices. In December 2025, the FDA approved a label update adding a meningioma warning to Depo-Provera - a key development for the litigation.
In February 2025, the Judicial Panel on Multidistrict Litigation consolidated Depo-Provera cases into MDL 3140 (In re: Depo-Provera Products Liability Litigation) in the Northern District of Florida before Judge M. Casey Rodgers. As of April 2026, approximately 3,490 cases are pending in the MDL, with an estimated 10,000 additional unfiled claims being held by plaintiffs' firms. Daubert and general causation hearings are scheduled for June 24-26, 2026, with the first pilot trials set for December 2026.
Do You Qualify? Common Eligibility Criteria
While every case is unique and requires individual attorney review, individuals who may have a viable Depo-Provera claim typically meet criteria similar to the following:
✓ Likely Qualifying Criteria
- Used Depo-Provera injectable contraceptive for one year or more
- Diagnosed with an intracranial meningioma (brain tumor on the meninges)
- Meningioma required treatment - surgery, radiation, or active monitoring
- Diagnosis occurred during Depo-Provera use or within a reasonable period after
- Experienced neurological symptoms, cognitive changes, or other complications
- Within the applicable statute of limitations for your state
Understanding Meningioma Diagnosis
Meningiomas are typically diagnosed via MRI or CT scan. They are classified by grade (1, 2, or 3), with Grade 1 being most common but potentially still requiring surgical intervention depending on size and location. Grade 2 and 3 meningiomas are more aggressive.
Other Synthetic Progestins
The 2024 BMJ study also found elevated meningioma risk with other high-dose progestins such as cyproterone acetate and chlormadinone acetate. Ongoing research is evaluating associations with additional synthetic progestins. If you were prescribed a progestin-based medication other than Depo-Provera, discuss your situation with an attorney.
Pfizer's Alleged Failures
Plaintiffs allege that Pfizer was aware of or had access to scientific data suggesting a meningioma association - particularly from European post-marketing data - and failed to update the Depo-Provera warning label or adequately inform the medical community for years, constituting a failure to warn under product liability law. The FDA approved a meningioma warning label update in December 2025, after the Dray et al. BMJ findings and the start of coordinated litigation - a timing sequence plaintiffs point to in support of their allegations.
MDL 3140: Current Litigation Posture
Depo-Provera cases were consolidated in February 2025 into MDL 3140 in the Northern District of Florida before Judge M. Casey Rodgers. As of April 2026, approximately 3,490 cases are pending in the MDL, with an estimated 10,000 additional unfiled claims. The court has scheduled Daubert and general-causation hearings for June 24-26, 2026, with the first pilot (bellwether) trials beginning in December 2026. Outcomes at the causation-evidence stage often set the trajectory for global settlement discussions.
