Depo-Provera Lawsuit Overview

What Is the Depo-Provera Lawsuit?

Thousands of women across the United States are filing lawsuits against Pfizer Inc. (formerly Pharmacia & Upjohn) alleging that the injectable contraceptive Depo-Provera (medroxyprogesterone acetate) caused them to develop meningiomas — tumors that form in the membranes surrounding the brain and spinal cord.

While meningiomas are typically classified as benign, they can cause severe health consequences including:

Chronic headaches and migraines
Vision problems and hearing loss
Seizures
Cognitive impairment and memory loss
Need for surgical removal, which carries significant risks

The Science Behind the Claims

A landmark 2024 study published in The BMJ found that prolonged use of medroxyprogesterone acetate (the active ingredient in Depo-Provera) was associated with a significantly increased risk of intracranial meningiomas. The study, conducted by French researchers analyzing over 18,000 meningioma cases, found that women who used injectable progestins for more than one year had a substantially elevated risk.

This research built on earlier findings from French health authorities that led to restrictions on medroxyprogesterone use in France and prompted similar reviews in other countries.

What Are Plaintiffs Alleging?

The lawsuits generally allege that Pfizer:

Knew or should have known about the link between Depo-Provera and meningiomas
Failed to adequately warn patients and healthcare providers about the brain tumor risk
Continued marketing the drug without sufficient safety disclosures
Prioritized profits over patient safety

Current Status of the Litigation

Cases are currently being filed in federal and state courts across the country. Attorneys expect that the volume of cases will lead to consolidation into a Multi-District Litigation (MDL), which would centralize pretrial proceedings before a single federal judge.

Key developments:

Growing case filings in multiple jurisdictions
MDL petition pending before the Judicial Panel on Multidistrict Litigation
No settlement has been reached — the litigation is in early stages

Why You Should Act Now

If you or someone you know used Depo-Provera and was diagnosed with a meningioma, time may be limited to file a claim. Statutes of limitations vary by state, and waiting too long could bar you from seeking compensation.
