Understanding Meningioma Risks From the Depo Shot
California women who were prescribed Depo-Provera as a birth control drug are finding out with increasing frequency that use of the drug has caused them to develop meningioma brain tumors. The birth control drug injury team at Walkup Personal Injury law is representing women across the state who were injected and have suffered this fate. Walkup has filed multiple cases against Pfizer and other defendants on behalf of women who have developed meningiomas.
The women Walkup represents were never warned of the risks of developing meningioma tumors. Medical research now shows a clear association between exposure to medroxyprogesterone acetate (the drug in Depo- Provera) and meningioma tumor growth.
California women who received the Depo shot and later developed a meningioma have the right to pursue a claim against the drug manufacturer. Our California Depo Provera Meningioma Lawyers have decades of experience handling complex pharmaceutical and medical-device litigation in California Superior Courts.
How Depo-Provera Works
Depo-Provera was marketed as a convenient, long-acting birth control option. An injectable contraceptive given every three months and containing depo medroxyprogesterone acetate (DMPA), prevents pregnancy by stopping ovulation and thickening cervical mucus. With repeated injections, it also exposes the body to elevated progestin levels over months or years. Many
California women relied on the shot because of its convenience, effectiveness, and long-acting formulation.
Current research including findings supported by UCSF’s women’s health researchers, has identified a relationship between long-term progestin exposure and the growth of meningioma brain tumors. Meningiomas can cause severe complications.
What Is a Meningioma?
Meningiomas form in the membranes surrounding the brain and spinal cord. Meningiomas are benign, meaning they are not cancer, but they are still dangerous. These tumors cause major harm as they grow and compress brain tissue. These tumors cause:
- Chronic headaches
- Visual disturbances or blurred vision
- Hearing problems
- Seizures
- Cognitive changes
- Balance issues, weakness, or numbness
Symptoms may appear years after Depo-Provera use began.
The connection to their Depo-Provera use is typically not discovered until an MRI or CT scan is ordered for symptoms such as persistent headaches, vision changes, or seizures and imaging reveals one or more meningiomas. Many find themselves lost in the dark, struggling to explain symptoms that don’t simply point to prolonged use of an injectable birth control shot, especially when it came with no warning. These women are not given the chance, power, or information needed to protect themselves or choose a safer option. Instead, they’re left picking up the pieces in the aftermath.
Research Linking Depo-Provera and Meningioma Development
Depo-Provera lawsuits allege Pfizer failed to warn patients and doctors about the risks tied to long-term use, including an association with meningioma. Plaintiffs allege Pfizer knew, or should have known, that medroxyprogesterone acetate had serious safety concerns, but kept selling and promoting the drug without meaningful warning updates.
Over the past decade, scientists have increasingly studied the relationship between hormonal contraceptives and meningioma growth. Several studies now indicate:
- Women who use Depo-Provera face an elevated risk of developing meningiomas, especially after extended or repeated exposure.
- These tumors frequently appear in areas of the brain sensitive to prolonged hormone stimulation.
- Some tumors grow slowly for years before symptoms become noticeable.
California Women Were Not Warned
Our clients report that:
- The risk of meningioma was never discussed during their appointments.
- They continued receiving injections for years without updated safety information.
- They were unaware of any need to monitor for neurological symptoms.
Clear warnings about meningioma risk have appeared on the drug’s label in other countries for years. When drug manufacturers do not provide full and accurate risk information, patients cannot make fully informed choices about their health.
A meningioma diagnosis is life-altering, especially when the tumor affects critical brain structures. The consequences may include:
- Loss of income or difficulty working
- Chronic pain or neurological symptoms
- Impaired cognitive function
- Significant lifestyle changes
- Emotional distress and anxiety
Women who trusted Depo-Provera as a safe long-term contraceptive option often feel betrayed and overwhelmed when facing a diagnosis they were never warned about. If this has happened to you, the Walkup Melodia Meningioma Lawsuit Attorneys can help and will defend your rights.

Frequently Asked Questions
1. What is a Depo-Provera lawsuit?
A Depo-Provera lawsuit is a legal claim filed by women who developed a meningioma after long-term use of the Depo shot. These claims allege that the medication’s manufacturer failed to warn about known or discoverable tumor risks.
2. How do I know if Depo-Provera contributed to my brain tumor?
Only a medical professional can diagnose the connection, but patterns such as extended Depo use, hormone-sensitive tumor characteristics, and imaging results often raise red flags that support a legal claim.
3. Do all Depo-Provera users develop meningiomas?
No. While most users will never experience this complication, research suggests that prolonged exposure may significantly increase risk for those with susceptible biology.
4. Can I file a claim if I stopped using Depo-Provera years ago?
Yes. Many meningiomas grow slowly over time, and symptoms may not appear until long after injections stop. An attorney can evaluate when your symptoms were discovered to determine whether your case is viable.
5. Will I need extensive medical records?
Yes. Imaging studies, Depo-Provera dosage history, and neurological evaluations help strengthen your claim and demonstrate medical causation.
6. How can a California Depo-Provera attorney help me?
An attorney reviews your medical history, consults with experts, handles communication with manufacturers, and builds the legal arguments necessary to pursue compensation for your injuries and losses.
