FAQ: What Are the Depo-Provera Lawsuits? 

The Depo-Provera lawsuits are legal claims filed by women who allege that use of the birth control shot caused them to develop intracranial meningiomas, a type of brain tumor. These lawsuits argue that the manufacturer, Pfizer, failed to properly warn patients and doctors about the potential risks. The cases have now been combined into a multidistrict litigation (MDL) to streamline the legal process and ensure consistent rulings.

What is Depo-Provera?

Depo Provera is a birth control shot that contains the hormone progestin. It is administered once every three months to prevent pregnancy. Although the product has been on the market for a while, safety concerns continue to mount.

How Depo-Provera Works

Depo-Provera works by releasing progestin, a synthetic form of the hormone progesterone, into the body. This hormone prevents ovulation, meaning no egg is released for fertilization. Additionally, it thickens cervical mucus to prevent sperm from reaching an egg and alters the uterine lining to prevent implantation.

Side Effects and Risks of the Depo Shot

Some users of Depo-Provera experience side effects. Of greatest concern is the link of Depo-Provera to intracranial meningiomas. Understanding this  risk is crucial for individuals considering Depo-Provera as a contraceptive method. It’s also why proper labeling is so important when it comes to pharmaceutical drugs.

Popularity Despite Concerns

Despite the known side effects, Depo-Provera remains a popular choice for birth control due to its ease of use. The shot is convenient for those who prefer not to take a daily pill or use other forms of contraception. The U.S. Centers for Disease Control and Prevention (CDC) reports that around 25% of sexually active women have used Depo-Provera at some point in their lives.

What Are the Concerns About Depo-Provera Meningiomas?

One of the main allegations against Depo-Provera is its potential link to brain tumors, specifically meningiomas. Meningiomas are typically benign tumors that form on the membranes covering the brain and spinal cord. These tumors are usually non-cancerous, but they can cause significant health problems, especially if they grow large or are located in sensitive areas.

Plaintiffs in the lawsuits claim that the drug’s manufacturer failed to adequately warn users about this serious risk.

The Complexity of Meningiomas

Meningiomas can vary significantly in their behavior and impact. Some remain small and asymptomatic, while others grow to a size that exerts pressure on the brain or spinal cord, leading to neurological symptoms. The location of the tumor is also significant, as tumors near critical brain regions can lead to serious complications, even if they are not cancerous.

What Is the Current Depo-Provera Lawsuit Landscape?

The legal actions against Depo-Provera makers are multi-faceted. Individual lawsuits claim the manufacturer did not provide sufficient warnings about the risks associated with the drug, leading to unexpected health issues. As a result, users claim they have suffered from medical problems that could have been avoided with proper disclosure.

In February 2025, the U.S. Judicial Panel on Multidistrict Litigation centralized Depo-Provera brain-tumor lawsuits as MDL No. 3140 in the U.S. District Court for the Northern District of Florida, before  Judge M. Casey Rodgers. The court  began immediately coordinating pretrial steps for all federal cases in one forum.

What Is a Multidistrict Litigation?

Multidistrict Litigation (MDL) is a special legal process used in the United States when many people file lawsuits in different courts that involve the same issue—such as a dangerous drug, medical device, or product. Instead of handling each case separately in different courts, the cases are combined and sent to one federal court under a single judge.

This consolidation helps make the process faster and more efficient because the judge can oversee all the pretrial steps, such as gathering evidence and hearing common arguments. Each person’s case remains separate, but the shared parts are handled together. Once those steps are finished, individual cases can still go back to their home courts for trial if needed.

Who Is Leading the Depo-Provera MDL?

On March 16, 2025, the court-appointed plaintiff leadership in the Depo-Provera multidistrict litigation. Levin Papantonio attorney Virginia Buchanan was named Co-Chair of the Plaintiffs’ Executive Committee and to the Trial Subcommittee.

These appointments place the firm in a leading position to organize discovery, coordinate filings, and advocate for women nationwide who allege Depo-Provera caused meningiomas.

Manufacturer’s Duty to Warn

The lawsuits against Depo-Provera hinge on the assertion that its manufacturer did not fulfill its duty to warn consumers of the risks. In drug manufacturing, companies are legally required to disclose potential side effects and risks associated with their products. Plaintiffs claim that had they been informed of the potential for developing brain tumors, they might have chosen alternative contraceptive methods.

The Role of Legal Precedent

Court decisions from other litigations can factor into the outcome of Depo-Provera lawsuits. Previous cases involving similar allegations against other pharmaceutical companies can influence the strategies that both plaintiffs and defense attorneys use. Law firms with experience handling drug injury lawsuits will be well positioned to anticipate potential challenges and opportunities in the courtroom.

The Role of Legal Counsel

A plaintiff’s lawyer will investigate a potential client’s claim that Depo-Provera caused her meningioma. This effort involves gathering medical records, talking to experts, calculating damages, negotiating settlements, and representing their client in court if the matter goes to trial.

Legal counsel also plays an essential role in demystifying legal terms for plaintiffs. Attorneys specializing in pharmaceutical lawsuits can provide valuable guidance and support, ensuring that clients understand the implications of each legal term and how it relates to their case. This knowledge empowers individuals to participate actively in their legal proceedings.

The Role of Regulatory Agencies

Regulatory agencies, such as the FDA, play a key role in monitoring the safety of drugs like Depo- Provera. These agencies review scientific research and provide guidance on product labeling and warnings. Their assessments can influence the legal landscape by informing court decisions and shaping public perception of a drug’s safety.

Who Can File a Depo-Provera Lawsuit?

You may be eligible to file a Depo-Provera lawsuit if the following apply to you:

1. You received at least two back-to-back injections of one of these products:

  • Pfizer’s brand-name Depo-Provera, or
  • Pfizer’s brand-name Depo-SubQ Provera, or
  • An authorized generic version of Depo-Provera made by one of the following manufacturers:
    Pharmacia & Upjohn Company LLC, Greenstone LLC, A-S Medication Solutions, Prasco Laboratories, or Preferred Pharmaceuticals Inc.

2. You were later diagnosed with meningioma (or possibly another type of benign brain tumor) after using Depo-Provera or Depo-SubQ Provera as described above.

If these criteria fit your situation, a drug injury attorney can review your medical history, evaluate your potential claim, and advise you on pursuing legal action against Pfizer, the manufacturer of Depo-Provera.

Is It Proven That Depo-Provera Causes Brain Tumors?

The question of whether Depo-Provera causes brain tumors is at the heart of these lawsuits. Some studies have suggested a potential link between progestin, the hormone in Depo-Provera, and the development of meningiomas.

The Current State of Research

Recent scientific studies have taken a closer look at whether long-term use of Depo-Provera (the contraceptive shot, also called depot medroxyprogesterone acetate or DMPA) may raise the risk of developing meningiomas. Here’s what has been found so far:

  • Large French Study (BMJ, 2024)
    Researchers examined health records from more than 18,000 women who had surgery for meningioma and compared them to over 90,000 women without the condition. They found that women who used Depo-Provera injections for one year or longer had about a five times higher risk of developing a meningioma. Short-term use did not show the same risk increase. Importantly, the study found no elevated risk with levonorgestrel IUDs.
  • Histopathology Study (Indonesia, 2022)
    Another study looked at tumor samples from women with meningiomas who had a history of Depo-Provera use. While it wasn’t designed to measure risk, it found biological patterns suggesting a possible link between the hormone and tumor growth.
  • Indonesian Case-Control Study (2018)
    A hospital-based study in Indonesia found that women who used Depo-Provera were more likely to develop meningiomas, especially when the injections were taken for long periods (over 10 years). The risk appeared stronger with the 3-month injection formulation.

What Are the Medical Issues for Depo-Provera Users?

Anyone using Depo-Provera should be aware of potential symptoms. Common symptoms associated with brain tumors include headaches, vision problems, and unexplained changes in behavior or mood. If you experience any of these symptoms, consider seeking immediate medical advice.

Recognizing Early Warning Signs

Early detection of symptoms can significantly impact the prognosis of brain tumors. Users of Depo-Provera should monitor their health and report any unusual symptoms to their healthcare provider promptly. Early intervention can lead to more effective treatment and better health outcomes.

Receiving Regular Medical Check-Ups

Regular medical check-ups are essential for women who are using Depo-Provera. These appointments provide opportunities for healthcare providers to assess any potential side effects and address patient concerns. Routine monitoring can also help detect symptoms early. This can facilitate timely medical intervention.

Seeking a Second Opinion

If you experience symptoms associated with brain tumors, it’s a good idea to seek a second opinion from a healthcare professional. Different specialists may offer varying perspectives on your condition, providing a more comprehensive understanding of potential health issues. This approach ensures you receive the most accurate diagnosis and appropriate care.
