What Is the Meningioma Lawsuit?

The meningioma lawsuit — formally known as MDL 3140 — is a federal multidistrict litigation filed against Pfizer, the manufacturer of Depo-Provera (medroxyprogesterone acetate). Plaintiffs allege that prolonged use of Depo-Provera caused them to develop meningioma brain tumors, and that Pfizer concealed or downplayed this risk for decades.

As of April 2026, more than 3,099 cases have been filed in MDL 3140, consolidated in the Northern District of Florida before Judge M. Casey Rodgers. The case count is growing approximately 47% per month, making this one of the fastest-growing pharmaceutical litigations in the country.

What Is a Meningioma?

A meningioma is a tumor that forms in the meninges — the protective membranes surrounding the brain and spinal cord. Although classified as typically non-cancerous (benign), meningiomas cause severe symptoms based on their size and location:

  • Persistent, worsening headaches
  • Vision changes, double vision, or vision loss
  • Cognitive problems, memory impairment, personality changes
  • Seizures
  • Hearing loss or tinnitus
  • Weakness or numbness in limbs

Many meningiomas require neurosurgery, stereotactic radiosurgery, or ongoing radiation therapy. Some are inoperable due to their location near critical brain structures.

The Link Between Depo-Provera and Meningioma

The connection between injectable medroxyprogesterone and meningioma has been building for over a decade, reaching a tipping point with a major 2024 study:

The 2024 BMJ Study

A landmark study published in the British Medical Journal by Peyre et al. analyzed health records of hundreds of thousands of women in France. The findings were unambiguous: women who used injectable medroxyprogesterone for one year or more had a 5.6 times greater risk of developing intracranial meningiomas. The risk was dose-dependent — longer use correlating with higher risk.

Why Medroxyprogesterone Is Different

Meningiomas express progesterone receptors. Medroxyprogesterone acetate (the active ingredient in Depo-Provera) is a synthetic progestin that binds powerfully to these receptors. Unlike oral contraceptives metabolized daily, a single Depo-Provera injection maintains elevated hormone levels for three full months, creating prolonged receptor stimulation that may promote tumor growth.

FDA Action

In December 2025, the FDA required Pfizer to add a meningioma warning to the Depo-Provera label. Plaintiffs argue this warning came more than 30 years after the drug was approved — and that Pfizer had access to the underlying science long before the BMJ study was published.

Do You Qualify for a Meningioma Lawsuit?

Qualifying Criteria

  • You received two or more Depo-Provera or generic medroxyprogesterone injections
  • You were diagnosed with a meningioma brain tumor (confirmed by MRI, CT, or biopsy)
  • You are within your state's statute of limitations (typically 2-3 years from diagnosis)
  • You have not already retained a law firm for this specific claim

Note on generic medroxyprogesterone: If you received generic medroxyprogesterone acetate instead of brand-name Depo-Provera, you may still qualify. The active ingredient and risk profile are identical.

What Compensation Is Available?

No global settlement has been reached in MDL 3140 as of April 2026. However, based on comparable mass tort litigations and the severity of meningioma injuries, potential compensation may include:

  • Medical expenses — neurosurgery, radiation, imaging, ongoing treatment
  • Lost wages — income lost during recovery
  • Pain and suffering — physical and emotional distress
  • Loss of enjoyment of life
  • Loss of consortium
Important: No attorney can guarantee a settlement amount. Anyone who promises specific dollar figures before litigation concludes should be viewed with skepticism.

The Timeline: What Happens Next

MDL 3140 is currently in the discovery phase. Key upcoming dates:

  • December 2026 — First bellwether trial scheduled
  • Bellwether outcomes will significantly influence global settlement negotiations
  • The MDL continues to grow — now is the time to join to preserve your rights

Frequently Asked Questions

What is the meningioma lawsuit?
The meningioma lawsuit (MDL 3140) involves claims that prolonged Depo-Provera use causes meningioma brain tumors. A 2024 BMJ study found a 5.6x increased risk. Lawsuits allege Pfizer failed to warn patients. Over 3,099 cases are filed as of April 2026.
Who qualifies for a meningioma lawsuit?
You may qualify if you used Depo-Provera or generic medroxyprogesterone for 2+ injections AND were diagnosed with a meningioma confirmed by MRI, CT, or biopsy, and are within your state's statute of limitations.
Is Depo-Provera the only drug linked to meningioma?
The current lawsuit focuses specifically on injectable medroxyprogesterone (Depo-Provera). Its unique delivery method creates sustained, high hormone levels for 3 months per injection — unlike oral contraceptives — which is believed to be the key driver of meningioma risk.
Is there a deadline to file a meningioma lawsuit?
Yes. Statutes of limitations vary by state — typically 2-3 years from diagnosis or discovery. Some states have shorter windows. Check your state's deadline at our state information page.
Does it cost anything to file?
No. Attorneys handling meningioma cases work on contingency — they only get paid if you receive compensation. There is no upfront cost for a case evaluation or filing.
