The Depo-Provera lawsuit involves a series of legal actions filed against Pfizer, the manufacturer of the Depo-Provera birth control injection, alleging that the drug causes serious health risks, particularly an increased risk of meningioma brain tumors. These lawsuits have gained traction following scientific studies linking long-term use of Depo-Provera to harmful side effects, and claims that Pfizer failed to adequately warn consumers in the United States despite acknowledging these risks in other countries. This article provides a detailed overview of the lawsuit’s background, allegations, legal claims, recent developments, and advice for potential claimants.
Background of the Depo-Provera Lawsuit
Depo-Provera is a contraceptive injection delivered every three months to prevent pregnancy and contains medroxyprogesterone acetate, a synthetic form of the hormone progesterone. Research published in 2024, notably from the British Medical Journal (BMJ), linked Depo-Provera to a significantly increased risk of developing meningiomas — brain tumors that can cause debilitating neurological symptoms and potentially require surgical intervention.
While Pfizer updated Depo-Provera’s packaging to mention the risk of meningiomas in Canada and the European Union as early as 2022, U.S. consumers were not warned until much later. This disparity fueled allegations that Pfizer knowingly withheld vital safety information from American patients and healthcare providers.
Parties Involved and Case Context
Plaintiffs in the lawsuits are women who were diagnosed with meningioma brain tumors after prolonged use of Depo-Provera or its authorized generic versions, such as Depo-SubQ Provera 104. The defendant is Pfizer Inc., headquartered in New York, which manufactures and markets the drug. The legal actions have been consolidated into a multidistrict litigation (MDL 3140) in the Northern District of Florida to streamline pretrial procedures and handle growing case numbers.
Details of the Depo-Provera Lawsuit Allegations and Claims
- Failure to Warn: Plaintiffs allege Pfizer did not provide adequate warnings regarding the risk of meningiomas in the U.S. market while disclosing such risks internationally.
- Design Defect: Claims that the 150 mg dosage formula used for decades unnecessarily overexposed women to high hormone levels, increasing tumor risks.
- Negligence and Misrepresentation: Pfizer’s alleged failure to update safety information despite emerging evidence, misleading healthcare providers and patients.
- Injuries and Damages: Women who developed meningiomas seek compensation for medical expenses, pain and suffering, lost wages, and other damages.
Legal Claims and Relevant Laws Involved in the Lawsuit
- Product Liability Law: Addressing defective design, manufacturing defects, and failure to warn of known hazards.
- Consumer Protection and Fraud Laws: Related to misleading marketing and nondisclosure of risks.
- Multidistrict Litigation (MDL) Procedures: Coordinating numerous lawsuits alleging similar harms for judicial efficiency.
Current Status and Recent Developments in the Lawsuit
As of August 2025, over 550 individual Depo-Provera lawsuits have been filed, with many cases pending in the MDL before Judge M. Casey Rodgers in Florida. Discovery is well underway, involving thousands of internal Pfizer documents concerning clinical trials, safety monitoring, and regulatory communications. In September 2025, oral arguments are expected on Pfizer’s motion to dismiss based on federal preemption, which, if successful, could limit state law claims.
Early bellwether cases have been selected to test key legal issues and influence potential settlement discussions, while additional state lawsuits continue to accumulate. Legal teams continue to lobby for broader class action certification and expedited resolution.
Consumer Advice and Recommendations
Women who have used Depo-Provera or authorized generics for more than a year and have been diagnosed with a meningioma brain tumor should consider consulting with specialized personal injury lawyers experienced in pharmaceutical litigation. It is important to preserve medical records, proof of drug usage, and diagnosis details to support claims.
Potential claimants should act promptly due to statutes of limitations and possible deadlines for filing claims within the MDL.

Conclusion: Significance and Future Outlook of the Depo-Provera Lawsuit
The Depo-Provera lawsuit represents a critical development in pharmaceutical accountability, emphasizing the necessity of timely, transparent risk communication to patients. The growing body of legal claims reflects increasing recognition of serious health impacts linked to contraceptive injections.
