What Is Depo-Provera?

Definition and Purpose


Depo-Provera is a brand name for medroxyprogesterone acetate, a synthetic form of the hormone progesterone. It's administered as an injection every three months to prevent ovulation, thereby serving as a contraceptive method.


Administration and Effectiveness

The injection is typically given in the upper arm or buttocks and provides pregnancy protection for up to 14 weeks. When used correctly, Depo-Provera is over 99% effective in preventing pregnancy.


Depo-Provera's Links to Brain Tumors

Recent Studies and Findings


In March 2024, a study published in the British Medical Journal revealed that women using Depo-Provera had a 5.6-fold increased risk of developing meningiomas, a type of brain tumor. 


Understanding the Risk Factors

The risk appears to correlate with the duration of Depo-Provera use, with longer usage linked to higher chances of tumor development. However, it's essential to note that while the relative risk increases, the absolute risk remains low.​

What Is a Meningioma?

Definition and Characteristics


A meningioma is a tumor that arises from the meninges, the protective membranes covering the brain and spinal cord. Most meningiomas are benign, meaning they're non-cancerous, but their location can still lead to significant health issues.​


Benign vs. Malignant Meningiomas


While benign meningiomas grow slowly and don't spread to other parts of the body, malignant meningiomas are aggressive and can invade nearby tissues. Both types can cause symptoms depending on their size and location.​


Types of Meningiomas

Classification Based on Location


Meningiomas are categorized based on their location in the brain or spinal cord, such as convexity, skull base, or spinal meningiomas.​


Classification Based on Grade


The World Health Organization classifies meningiomas into three grades:​

  • Grade I: Benign and slow-growing.​

  • Grade II: Atypical, with a higher likelihood of recurrence.​

  • Grade III: Malignant and aggressive.​


Symptoms of Meningiomas

Common Neurological Symptoms


Symptoms vary based on the tumor's size and location but can include:​

  • Headaches​

  • Seizures​

  • Vision problems

  • Hearing loss

  • Memory loss​

  • Weakness in limbs


Severity and Progression

Some meningiomas remain asymptomatic for years, while others may cause rapid symptom progression, necessitating immediate medical attention.​


How Might a Meningioma Impact Me?

Physical and Cognitive Effects


Depending on its location, a meningioma can affect motor functions, balance, cognitive abilities, and sensory perceptions.​


Emotional and Psychological Impact

The diagnosis of a brain tumor can lead to anxiety, depression, and emotional distress, impacting the overall quality of life.​


Treatment Options for Meningiomas

Surgical Interventions


Surgery is often the primary treatment, aiming to remove as much of the tumor as possible without damaging surrounding tissues.​


Radiation Therapy and Other Treatments


For tumors that can't be entirely removed or are malignant, radiation therapy may be employed. Other treatments include observation for small, asymptomatic tumors and medications to manage symptoms.​


Depo-Provera Allegations Against Pfizer

Overview of Legal Claims


Recent studies have linked Depo-Provera to an increased risk of developing meningiomas, leading to a surge in legal actions against Pfizer, the drug's manufacturer. Plaintiffs allege that Pfizer failed to adequately warn users about these potential risks, resulting in serious health complications.


Basis of the Allegations


The core of these lawsuits centers on the claim that Pfizer was aware, or should have been aware, of the heightened risk of brain tumors associated with Depo-Provera but did not provide sufficient warnings to consumers or healthcare providers.

Pfizer's Response to the Allegations

Company's Official Statements


Pfizer has acknowledged the studies linking Depo-Provera to an increased risk of meningiomas but maintains that the medication has been a safe and effective contraceptive option for millions of women over the past three decades. The company has stated its intention to vigorously defend against these lawsuits. ​


Measures Taken Post-Allegations

In response to the emerging studies, Pfizer has collaborated with regulatory agencies to update product labels and patient information leaflets to include warnings about the potential risk of developing meningiomas with long-term use of Depo-Provera. 


The Legal Path for Depo-Provera Victims

Understanding Product Liability


Product liability law holds manufacturers accountable for producing and distributing products that are safe for consumer use. In the case of Depo-Provera, plaintiffs argue that Pfizer's failure to warn about the potential risks constitutes a breach of this responsibility. ​


Steps to Initiate Legal Action

If you believe you've been adversely affected by Depo-Provera, consider the following steps:


  1. Consult a Specialized Attorney: Seek legal counsel experienced in pharmaceutical litigation to assess the viability of your case.​

  2. Gather Medical Records: Compile all relevant medical documentation, including records of Depo-Provera injections and any diagnoses related to meningiomas.​

  3. File a Lawsuit: Your attorney will guide you through the process of filing a lawsuit, which may involve joining a class-action suit or pursuing an individual claim.​



How Can a Depo-Provera Lawsuit Lawyer Help?

Role of Specialized Attorneys


Attorneys specializing in Depo-Provera lawsuits possess the expertise to navigate the complexities of pharmaceutical litigation. They can evaluate your case, gather necessary evidence, and advocate on your behalf to seek compensation for medical expenses, lost wages, and pain and suffering. ​


Benefits of Legal Representation

Engaging a specialized lawyer increases your chances of a favorable outcome. They can negotiate settlements, represent you in court, and ensure that your rights are protected throughout the legal process.



Who Qualifies for a Depo-Provera Lawsuit?

Eligibility Criteria


Individuals who have used Depo-Provera and subsequently developed meningiomas may qualify for a lawsuit. Eligibility often depends on factors such as the duration of Depo-Provera use and the timing of the meningioma diagnosis.


Evidence and Documentation Required

To support your claim, you'll need to provide:​


  • Medical records confirming Depo-Provera usage.​

  • Diagnostic reports of meningioma.​

  • Documentation of medical treatments and associated costs.​


Depo-Provera Lawsuit Settlements

Overview of Settlement Processes


Settlement processes involve negotiations between the plaintiff's legal team and Pfizer to reach a mutually agreeable compensation without proceeding to trial. These negotiations consider the strength of the evidence, the severity of the injury, and the impact on the plaintiff's life. ​


Factors Influencing Settlement Amounts

Several factors can influence the settlement amount, including:


  • The severity of the meningioma and its impact on the plaintiff's health.​

  • Medical expenses incurred, both past and future.​

  • Lost wages and diminished earning capacity.​

  • Non-economic damages such as pain and suffering.​


Ongoing Depo-Provera Meningioma Lawsuits

Current Status of Litigations


As of March 2025, numerous lawsuits have been filed against Pfizer, with cases consolidated into multidistrict litigation (MDL) to streamline proceedings. This consolidation allows for more efficient handling of pretrial matters and consistent rulings across cases.


Notable Cases and Outcomes


While many cases are still in the early stages, some have reached settlements. For instance, in February 2025, a significant settlement was reached in a case where the plaintiff developed a meningioma after prolonged Depo-Provera use. Details of the settlement remain confidential.
