Depo-Provera Brain Tumor Lawsuits: Legal Help for Women Diagnosed With Meningioma

Women who received Depo-Provera birth control shots and were later diagnosed with a meningioma brain tumor or spinal tumor may be eligible to file a lawsuit against Pfizer. Large-scale research has linked long-term use of the injectable contraceptive to a significantly higher risk of meningioma. Federal lawsuits are consolidated in a multidistrict litigation (MDL) in Florida. In June 2026, Pfizer reached an agreement to resolve about 80% of federal cases, but deadlines still apply.

For millions of women, Depo-Provera seemed like a simple choice. Visit the doctor, get a shot every three months, and stop worrying about a daily pill. Few women were ever told that the injection might carry a risk of brain tumors.

Today, many of those women face headaches, vision changes, seizures, memory problems, or brain surgery. Some live with permanent neurological damage. Many are asking the same question: Why wasn’t I warned?

At Walch Law, we represent women who believe Depo-Provera harmed them. This page explains what the research shows, where the litigation stands, who may qualify, and what steps you can take now to protect your rights.

What Is Depo-Provera?

Depo-Provera is the brand name for medroxyprogesterone acetate, an injectable hormonal contraceptive manufactured by Pfizer. It contains a synthetic form of progesterone, a hormone that prevents pregnancy by stopping ovulation.

A healthcare provider gives the injection in the arm or buttock about every 12 to 13 weeks. A lower-dose version, Depo-SubQ Provera 104, is injected under the skin. Doctors also sometimes prescribe medroxyprogesterone to treat endometriosis-related pain and other conditions.

The U.S. Food and Drug Administration (FDA) approved Depo-Provera for contraception in 1992. Since then, it has become one of the most widely used birth control methods in the country, especially among younger women and women who want long-acting protection.

The Link Between Depo-Provera and Meningioma Brain Tumors

What Is a Meningioma?

A meningioma is a tumor that grows from the meninges, the protective layers of tissue covering the brain and spinal cord. Most meningiomas are classified as noncancerous. That label can be misleading.

As a meningioma grows, it presses on the brain, nerves, and blood vessels. Depending on its size and location, it can cause:

• Chronic or worsening headaches
• Vision problems, including blurred or double vision
• Hearing loss or ringing in the ears
• Seizures
• Memory loss and trouble concentrating
• Personality or mood changes
• Weakness or numbness in the arms or legs
• Speech difficulties
• Balance problems

Treatment often involves brain surgery, radiation, or both. Even after successful treatment, some women live with lasting complications, such as seizures, cognitive decline, or vision loss. Some tumors return.

What the Research Shows

Doctors have long known that many meningiomas have hormone receptors, meaning hormones like progesterone can influence their growth. Researchers have now studied whether synthetic progestins, including medroxyprogesterone acetate, raise the risk of these tumors.

The most significant evidence came from a large-scale French study published in The BMJ in March 2024. Researchers analyzed national health data covering thousands of women who had surgery for intracranial meningioma. They found that prolonged use of medroxyprogesterone acetate, one year or longer, was associated with a 5.6-fold increased risk of meningioma requiring surgery.

Additional research has since examined U.S. patient data and reported similar associations, reinforcing concern that cumulative exposure may matter more than short-term use. The risk appears to increase with higher doses and longer duration of treatment, while evidence for occasional or brief use remains less clear. Because meningiomas can grow slowly and may not cause symptoms until they are larger, clinicians may consider a patient’s history of hormonal therapy when evaluating persistent headaches, visual changes, seizures, or other neurological symptoms.

Patients should not stop prescribed hormonal medication abruptly without discussing it with a clinician, since the benefits and risks vary by drug, dose, and individual medical history. In some circumstances, switching to a different formulation or using the lowest effective dose for the shortest appropriate duration may be considered. Regular review of ongoing treatment can help ensure that therapy remains aligned with current symptoms, goals, and emerging safety information.

How Much are These Cases Worth?

Compensation in hormone therapy injury cases depends on the severity of the harm, the evidence connecting the medication to that harm, medical expenses, lost income, and the effect on daily life. Claims may also consider future treatment needs, reduced earning capacity, pain and suffering, and, in some cases, punitive damages where conduct was especially egregious.

Because every case turns on its own medical history and available evidence, there is no reliable “average” value that applies to all hormone therapy claims. A qualified attorney can review medical records, prescription history, expert opinions, and documented losses to help estimate the potential value of a claim. There is no standard settlement amount, and advertisements describing large verdicts do not guarantee a similar outcome in another case. An attorney can review medical records, prescription history, diagnosis dates, and applicable filing deadlines to provide a more individualized assessment.

Because these cases can involve complex medical and legal questions, it is important to preserve relevant records and seek advice promptly. Medical bills, pharmacy receipts, treatment notes, employment records, and correspondence with healthcare providers may help document both exposure and damages.
