➢ Depo-Provera Linked to Meningioma Brain Tumors
A study published in 2024 by the British Medical Journal found that Depo-Provera users face an increase risk of developing a type of brain tumors known as meningioma. According to the study, women who used the Depo shot were 5.76 times more likely to be diagnosed with these tumors.
Meningioma is a type of benign – or non-cancerous – brain tumor that can form in the tissue surrounding the brain or the spinal cord. Some of the symptoms of intracranial meningiomas include:
- Blurred vision
- Headaches
- Numbness
- Seizures
Although meningiomas are benign, women who are diagnosed with these tumors after using Depo-Provera may be forced to undergo brain surgery in order to have them surgically removed, which can place them at risk of serious additional complications.
➢ Depo-Provera Lawsuits Filed by Women with Brain Tumors
The first Depo-Provera lawsuit involving brain tumors linked to the birth control shot was filed in October 2024 by a California woman who was diagnosed with meningioma after using the Depo shot.
Several additional Depo shot lawsuits have subsequently been filed in California and Indiana against Pfizer – the manufacturer of Depo-Provera – by other women who were diagnosed with meningioma brain tumors after using the birth control injection. As of January 2026, at least 1,400 Depo-Provera lawsuits have been filed so far in the U.S.
These lawsuits have alleged that Pfizer’s Depo-Provera shot increases the risk of developing intracranial meningioma, and that the drugmaker failed to adequately warn women and doctors about the risk of brain tumors from using this medication.
Legal experts monitoring the Depo-Provera litigation predict that additional claims against Pfizer will be filed in the coming months as more women learn about the link between the birth control shot and brain tumors.
In September 2025, a class action lawsuit against Pfizer was filed in Florida involving brain tumors linked to Depo-Provera. Many of the individual lawsuits against Pfizer have also been consolidated in a multidistrict litigation, or MDL, in Florida.
➢ Who Is Eligible to File a Depo-Provera Lawsuit?
Women who used the Depo shot and were later diagnosed with brain tumors may be eligible to file a lawsuit if they meet all of the following case criteria:
- Used Depo Provera or Depo SubQ Provera 104 for birth control;
- At least one year (four injections) of Depo Provera use;
- Diagnosed with cerebral meningioma brain tumors.
If you or a member of your family answered “yes” to all of the above criteria, you may qualify to take legal action and receive compensation.

➢ More Information About Depo-Provera Shots
Depo-Provera (medroxyprogesterone acetate) is an injectable form of birth control which lowers the risk of pregnancy using the hormone progestin. The contraceptive injection is sold under the brand names Depo-Provera and Depo-SubQ Provera 104, as well as in “authorized generic” versions of the shot.
Women who use the Depo shot for birth control receive an injection from their doctor, gynecologist, or other health care provider every three months. This injection helps to prevent pregnancy by blocking ovulation and thickening the cervical mucus to prevent sperm from reaching the egg.
Studies have shown that Depo-Provera is 94% effective at preventing pregnancy. Clinical trial data showed that the subcutaneous version of the Depo shot, Depo-SubQ Provera 104, is equally effective at preventing pregnancy, but because the drug is newer, this data may not reflect the injections actual effectiveness under typical use.
