Erin Brockovich is leading the fight!
We trusted the manufacturers of Depo Provera and we were betrayed. For years, I have received emails and messages from women who have suffered from taking Depo Provera. Accountability matters. We deserve transparency about the risks of anything going into our bodies - not silence and excuses. It is time to stand up and demand better.

Accountability matters. If a product harms people, those responsible must step up, admit the problem, and fix it. Women deserve transparency about the risks they face taking Depo-Provera — not silence or excuses.”

The link between Depo-Provera and brain tumors
For women seeking birth control options, Depo Provera appeared to offer a safe, convenient option to prevent pregnancy. Rather than trying to remember to take a daily pill, the contraceptive was given as an injection every three months.

Unfortunately, Pfizer Inc., the major pharmaceutical company, along with related entities, behind the popular birth control brand, failed to warn users about the dangers and full scope of health complications after prolonged use. Now, women from around the United States have come forward to hold drug companies accountable for injuries suffered under a variety of legal theories including failing to warn users of the dangers of taking the drug, product liability, and negligence.
Pfizer failed to include meningioma risk on warning label
Research has emerged showing that women who’ve used Depo-Provera, containing a synthetic form of the hormone progestin, face heightened risks of developing meningiomas. These are serious tumors affecting the brain and spinal cord that can cause severe headaches, vision and hearing loss, muscle weakness, and seizures — negatively impacting a person’s quality of life.

If a tumor goes undetected in the brain long enough, it can become life-threatening. While meningiomas can be benign, these tumors often require invasive surgeries, regular scans, and ongoing health monitoring and treatment to keep track of potential tumor growth.

What is Depo-Provera? A look into the popular contraceptive injection
Depo-Provera and Depo-SubQ Provera 104 are contraceptive injections used to prevent pregnancy and regulate the menstrual cycle. This form of birth control contains medroxyprogesterone acetate, which is a synthetic form of the hormone progesterone.

Women who take Depo-Provera receive injections from their health provider every three months — providing a more convenient option than taking a daily pill. When administered correctly, the drug is 99% effective at preventing pregnancy.

The drug is manufactured by Pfizer and was first approved by the FDA for contraceptive use in 1992.

Weighing meningioma brain tumor risks
A meningioma is a tumor that has grown on the brain or spinal cord. It is a serious medical condition that can cause pressure on the brain and lead to a range of severe and potentially debilitating symptoms, including:
Headache and migraines
Muscle weakness
Seizures
Vision and hearing loss
Speech difficulties
Meningioma brain tumors require invasive surgeries and ongoing health monitoring and treatment to track the tumor growth.

Due to the vulnerable location of these growths, surgery interventions could lead to further health complications down the line.
What you should know about the 
Depo-Provera lawsuit
A recent study by the British Medical Journal found an alarming connection between women using Depo-Provera and meningioma brain tumors. According to scientists, women who used Depo Provera for more than one year were more than 5.6x more likely to develop meningiomas. 


The study also found that Depo-Provera’s maker, Pfizer, knew about meningioma incidences and failed to adequately warn users about the increased health risks.



Our law firm partners are working to hold Pfizer and others accountable for the injuries associated with developing meningiomas. If you’ve taken Depo-Provera and have been diagnosed with a meningioma, you may be entitled to damages.

Depo-Provera Lawsuit: Case Timeline

January 30, 2025

The Judicial Panel on Multidistrict Litigation will consider a motion to establish a Multidistrict Litigation, also known as an “MDL, for cases related to the contraceptive Depo-Provera, which has been linked to an increased risk of brain tumors, specifically meningiomas. This hearing will occur at the Wilkie D. Ferguson, Jr. U.S. Courthouse in Miami, Florida. Usually, the parties seek to create an MDL when cases have been filed in various states. If the MDL is approved, these cases that have been filed in various courts are transferred to one designated Federal Court,  in front of a specific Federal Judge.  This is done to create a more efficient pre-trial process, where the parties can seek rulings on pre-trial issues from one judge. It is expected that an MDL will be established in the weeks after the January 30 hearing.

November 26, 2024

Attorneys for Plaintiffs filed a motion to centralize at least 22 pending lawsuits into a federal multidistrict litigation (MDL) aimed at consolidating cases related to the alleged risks of Depo-Provera into one jurisdiction for efficiency.

October 1, 2024

Kristina Schmidt filed the first lawsuit against Pfizer Inc. and other defendants in California federal court. Schmidt alleged that her long-term use of Depo-Provera, which began in 2005, resulted in a meningioma diagnosis in June 2022, necessitating brain surgery. The lawsuit claims that Pfizer was aware of the risks associated with the drug but failed to adequately warn users.

March 27, 2024

A significant study published in the British Medical Journal indicated that long-term use of Depo-Provera is associated with a 5.6 times higher risk of developing meningiomas compared to non-users. This study provided critical evidence supporting claims made in the lawsuits.

Frequently Asked Questions
What is Depo-Provera?
Depo-Provera is a hormonal contraceptive injection containing medroxyprogesterone acetate, a synthetic form of the hormone progesterone. It is administered every three months to prevent pregnancy. Depo-Provera works by suppressing ovulation, thickening cervical mucus to block sperm, and thinning the uterine lining to prevent implantation.

Commonly used by women seeking a long-term, reversible contraceptive method, Depo-Provera is highly effective, with a success rate of over 99% when used correctly. However, it is associated with various known side effects, such as weight gain, mood changes, decreased bone density, and menstrual irregularities. Based upon research published in March 2024, users of Depo-Provera face a 5.6 times greater chance of developing meningiomas, a form of brain tumor, than those who do not use Depo-Provera. Despite this, the makers of Depo-Provera do not warn women about this risk.
What is a mass tort? What is a mass tort lawsuit?
A Mass Tort is a legal action where a large number of plaintiffs bring lawsuits against one or several defendants for harm caused by common actions or products. Unlike a class action, where plaintiffs are treated as a single entity, in a mass tort, each plaintiff's case is handled individually, but they are grouped together for the purpose of certain legal proceedings like discovery and trial phases, which makes the administration much for efficient.

Mass torts typically arise in cases involving:
• Defective products (e.g., medical devices, pharmaceuticals)
• Toxic exposure (e.g., environmental contamination, chemicals like PFAS)
• Catastrophic events (e.g., wildfires, plane crashes, industrial accidents)

These cases allow for more personalized representation compared to class actions since the injuries and damages experienced by each plaintiff can vary widely. However, they share common legal issues and evidence, which justifies the collective handling in a mass tort framework.
