Thousands of women are suing Pfizer over claims that its birth control shot caused brain tumors. A major trial is now set for December 7, 2026.
Legal Action Grows
More than 2,100 women in the US have filed lawsuits. They claim Pfizer did not warn them about the risk of meningiomas.
These are benign tumors that grow in the brain or spine. However, they can still cause blindness, memory loss, and seizures.
High Risk Found
Depo-Provera is an injection given every three months to 2 million women annually. It uses the synthetic hormone progestin to prevent pregnancy.
Recent studies show a 500 percent increased risk of brain tumors. This risk can remain long after a woman stops using the shot.
Belated Safety Warnings
Last month, Pfizer finally added a warning label to the product. Attorney Virginia Buchanan called the change long overdue and critical for health.
Experts believe progestin overstimulates receptors in the membranes lining the skull. This may cause cells to mutate and form tumors.
Life-Changing Effects
Symptoms often include impaired hearing and vision or behavioral changes. Some women require brain surgery if the tumor compresses critical nerves.
Finally, lawyers expect the number of filings to continue rising. Pfizer maintains the product is safe but has updated the FDA label.
“It’s a scary thing to think you have an inoperable brain tumor.”
