Meningiomas are non-malignant tumors that grow from the meninges. Meningiomas are not usually cancerous but can press on the brain, nerves, or vessels and cause pain, symptoms, and disability. Treatment usually requires surgery to remove the tumor. Surgical removal of these tumors has risks due to the possibility of nerve or brain damage.

Depo Provera Drug History and Risks

The development of Depo-Provera dates back to the 1950s. It was initially introduced in 1960 as an injection for treating endometrial and renal cancer. Depo-Provera was approved for contraception in international markets, including France, as early as 1969.

The FDA finally approved Depo-Provera as a contraceptive in 1992. The maker was Upjohn a company owned by Pfizer.

Based on medical research, there is an association between the use of Depo-Provera (depot medroxyprogesterone acetate or DMPA) and an increased risk of developing meningiomas. Meningiomas are often progesterone-receptor-positive tumors. Since Depo-Provera is a progestogen, it can potentially stimulate the growth of these tumors through these receptors.

  • The risk appears to be dose and duration-dependent
  • Higher cumulative doses over longer periods show stronger associations
  • Several studies have shown an increased incidence of meningiomas in long-term Depo-Provera users
  • The risk may be reversible, with some studies showing tumor regression after discontinuation of the medication

Litigation and Regulatory Action

We are involved in evaluating litigation against Pfizer, the manufacturer of Depo Provera. Our efforts focus on whether Kaiser and Pfizer failed to adequately warn patients and healthcare providers about the potential risk of developing meningiomas.

The first lawsuits began emerging in France, where studies showed a strong connection between prolonged use of progestins (including Depo Provera) and meningioma development. This led to regulatory action in France and increased scrutiny worldwide.

Current Cases Worldwide

In the United States, cases which have been filed to date allege that:

  • Pfizer knew or should have known about the risk of meningioma
  • The company failed to provide adequate warnings about this risk
  • Patients developed meningiomas after using the drug
  • Many patients required surgery to remove these tumors

  • A major French study showed that women using high-dose progestins had up to 20 times higher risk of developing meningiomas
  • By 2021, French health authorities (ANSM) implemented strict restrictions on high-dose progestin use
  • They required informed consent forms specifically addressing the meningioma risk

Pharmacovigilance Reports:

  • The European pharmacovigilance database (EudraVigilance) began receiving increased reports of meningiomas associated with progestin use.
  • Cases typically involved:
    • Long-term use (often 5+ years)
    • Multiple meningiomas in some patients
    • Cases requiring surgical intervention
    • Tumor regression after drug discontinuation in some cases

Regulatory Response:

  • The European Medicines Agency (EMA) reviewed the evidence
  • Several European countries implemented stronger warning requirements
  • Some countries restricted high-dose progestin prescriptions
  • Required brain MRI monitoring for long-term users in certain cases

MEDICAL RESEARCH IDENTIFIES AN INCREASED RISK OF BRAIN TUMOR

A 2025 medical journal article found a compelling association between Depo-Provera injections and the development of meningioma tumors in women who received the drug for birth control purposes between ages 19-49. “The Association between Medroxyprogesterone Acetate Exposure and Meningioma” by Russell L. Griffin from the Department of Epidemiology, School of Public Health, The University of Alabama at Birmingham, found that with injectable Depo Provera (Medroxyprogesterone acetate aka MPA) there was a 53% increased odds of developing being a cerebral meningioma. That association became stronger with the longer duration of injection of MPA. The author concluded that his study was consistent with the prior medical literature, which reported an association between injection exposures to MPA and a stronger association with increasing use of MPA.

PROGESTERONE IS RELATED TO CEREBRAL MEINGIOMAS

Medroxyprogesterone acetate is a synthetic progesterone in the family of progestins. For birth control, it can be injected as a 150 mg intramuscular injection or a 104 mg subcutaneous injection. Progesterone is thought to be an important factor in the pathophysiology of meningiomas, which are mostly slow-growing, benign tumors that account for approximately one-third of all intracranial tumors. Such tumors are known to be more prevalent among women, with the ratio approaching 3:1 female–male.

Pharmacia & Upjohn developed Depo-Provera in the ‘50s and got FDA approval in the 1960s for other indications. They ultimately received approval for contraception in 1992. Pfizer bought Pharmacia & Upjohn in 2002 just as the patent was expiring, and shortly thereafter, Greenstone was formed to be the authorized generic seller. Pfizer owned Greenstone and Pharmacia & Upjohn until November 2020, when Greenstone and Upjohn were spun off to form Viatris.

NO US WARNINGS

As far as warnings about meningioma development, there has been no mention of Meningioma in US drug labeling. By contrast, Meningioma was listed as an adverse reaction in a Canadian medical monograph as early as 2015. In 2024, the label in Europe was changed to add: “Meningioma: Meningiomas have been reported following long-term administration of progestogens, including medroxyprogesterone acetate. Depo-Provera should be discontinued if a meningioma is diagnosed. Caution is advised when recommending Depo-Provera to patients with a history of meningioma”
