Depo-Provera is an injectable contraceptive given every three months. Many women have found it a convenient and effective method of family planning.
However, recent studies have shown a correlation between long-term use of the contraceptive and the development of a specific type of brain tumor. Our attorneys have filed lawsuits against the drug’s manufacturer, Pfizer. The role of medical evidence in Depo-Provera lawsuits will be critical in ensuring women who suffered these side effects receive appropriate compensation.
Depo-Provera is a synthetic version of a naturally occurring hormone. It was first developed in the 1950s and prescribed in the 1960s as a chemotherapy agent. The federal Food and Drug Administration approved it for use as a contraceptive in 1992.
In the spring of 2024, The British Medical Journal (BMJ) published a study showing a correlation between long-term use of Depo-Provera and the development of a specific type of brain tumor called meningioma. This type of tumor is typically benign but can produce debilitating symptoms depending on its size and location in the brain.
The BMJ study examined the records of more than 20,000 women and found the chances of developing meningioma were more than five times higher among women who had at least three Depo-Provera injections. The size of the study and its publication in a prestigious peer reviewed journal lend credibility to the claim that Depo-Provera causes meningioma. The attorneys at Phillips Law Group will use this clinical study and other scientific data to prove that Pfizer should fairly compensate the affected women.
Women diagnosed with meningioma began filing lawsuits against Pfizer and other manufacturers of Depo-Provera in early 2024. The lawsuits allege that Pfizer did not provide adequate warning of the brain tumor risk associated with long-term use of the contraceptive injections.
Scores of lawsuits were filed across the country, and in early 2025 the cases were consolidated into a multidistrict litigation, sometimes called a mass tort. Managing the cases as a mass tort action is more efficient for all parties and can result in a more favorable settlement.
If the lawsuits are successful, plaintiffs can collect compensation for their expenses and losses suffered due to their brain tumor. They can also claim damages for their diminished quality of life. Phillips Law Group is currently handling inquiries from women considering joining the Depo-Provera lawsuits and can manage the litigation for those eligible to participate.
There are several qualifications a woman must meet to join the mass tort. A skilled attorney will review a potential plaintiff’s medical records to ensure they meet the eligibility criteria.
A qualified plaintiff will have had at least three injectable doses of Depo-Provera. A licensed medical professional must have diagnosed the woman with meningioma sometime after she took the drug. If a potential plaintiff took other hormone-altering medications before developing meningioma, they may be ineligible to participate in the lawsuit.
Women who do not qualify for the mass tort lawsuit but have suffered health impacts from taking Depo-Provera may have other legal options available to them. An attorney can advise you whether there are grounds to proceed with legal action in a specific case.
Many women used Depo-Provera as a contraceptive, but Pfizer never warned patients about the risk of developing brain tumors. Women who developed meningioma after taking Depo-Provera are suing Pfizer for its failure to warn of this potentially devastating side effect.
The role of medical evidence in Depo-Provera lawsuits is crucial. Your medical records must prove that you received several Depo-Provera injections before developing meningioma. If you believe you may qualify, contact Phillips Law Group immediately for a free, no-obligation consultation.
