Recent research has examined a possible connection between Depo-Provera and brain tumors called meningiomas. This has coincided with over a thousand lawsuits against Pfizer. If you've used Depo-Provera birth control injections for a year or more, it may be helpful to understand the early warning signs of a meningioma. The symptoms can be subtle at first, often mistaken for stress or aging, which is why knowing what to watch for is critical, especially if you've received multiple Depo-Provera injections over months or years.
Why Meningioma Concerns Have Emerged for Depo-Provera Users
Research published in March 2024 linked Depo-Provera and meningiomas. The active ingredient in Depo-Provera, medroxyprogesterone acetate, is a synthetic form of progesterone. Meningiomas often have progesterone receptors, meaning the hormone can act as fuel for tumor growth in some cases. While regulators in Canada, the United Kingdom, and Europe added meningioma warnings to Depo-Provera labels years ago, the U.S. FDA only approved a label change in December 2025 to include additional risk information.
What Is a Meningioma?
Meningiomas are tumors that develop in the meninges, the protective membranes surrounding the brain and spinal cord. They are the most common type of tumor found in the head, accounting for approximately 30% of all brain tumors in the United States. Most meningiomas grow slowly over many years, and symptoms often do not appear immediately. While the majority are benign, their location and size can still cause serious health complications by pressing on brain tissue, nerves, or blood vessels.
Early Warning Signs and Symptoms of Meningioma
Meningioma symptoms vary widely depending on the tumor's location in the brain or spinal cord. Common warning signs include persistent headaches, changes in vision such as blurred or double vision, hearing loss or ringing in the ears, memory problems or difficulty concentrating, seizures, weakness in the arms or legs, numbness in the extremities, dizziness or loss of balance, and personality or behavioral changes.
More specific symptoms can occur depending on where the tumor develops. Some may cause vision problems or bulging eyes, while others can lead to facial weakness, difficulty swallowing, or changes in speech. Some women have reported experiencing severe vertigo, confusion, or even difficulty understanding language before their diagnosis.
Of course, these symptoms don't always indicate a meningioma, but if you've used Depo-Provera for an extended period and are experiencing any combination of these signs, you may want to seek medical evaluation promptly.
Why Meningioma Symptoms Are Often Missed
One of the most challenging aspects of meningioma detection is that the symptoms can be easily overlooked or misattributed to other causes. Because meningiomas typically grow very slowly, the changes they cause can be gradual and subtle. Often, many patients may not notice symptoms until the tumor has grown significantly, and in some cases, symptoms are mistaken for normal signs of aging.
Some people dismiss persistent headaches as stress-related, attribute memory issues to hormonal changes, or explain away vision problems as needing new glasses. This delay in recognition can allow tumors to grow larger before diagnosis, potentially making treatment more complex. Additionally, because many healthcare providers were not warned about the Depo-Provera connection until recently, the link between contraceptive use and neurological symptoms may not have always been considered during routine medical visits.
How Meningioma Findings May Relate to Depo-Provera Lawsuits
The research examining a possible association between Depo-Provera and meningiomas has sparked a wave of legal action against Pfizer. More than one thousand lawsuits have been filed alleging the company knew or should have known about the brain tumor risk, but failed to adequately warn patients and healthcare providers in the United States. These cases have been consolidated into a multidistrict litigation case in the Northern District of Florida.
Lawsuits allege that Pfizer provided more detailed risk information to foreign regulators than to the FDA, downplayed epidemiological studies, and disregarded decades of evidence linking synthetic progestins to meningioma growth. Women who developed meningiomas after using Depo-Provera may be eligible for compensation covering medical expenses, lost wages, pain and suffering, and ongoing treatment costs. Some cases involve women who require invasive brain surgery, radiation therapy, or face permanent neurological damage.
