Depo-Provera Brain Tumors
Pfizer's injectable contraceptive has been linked to intracranial meningiomas. If you developed a brain tumor after using Depo-Provera, you may have a legal claim.
What Is the Depo-Provera Lawsuit?
Depo-Provera is an injectable contraceptive manufactured by Pfizer that has been used by millions of women worldwide for decades. Recent scientific research and litigation have raised serious concerns that prolonged use of the drug is associated with a significantly elevated risk of developing intracranial meningiomas — tumors that grow on the membranes surrounding the brain and spinal cord.
A landmark study published in the British Medical Journal found that women who used progestogen-based injectable contraceptives like Depo-Provera for more than one year had a dramatically higher risk of developing meningiomas compared to non-users. Legal actions are now forming against Pfizer, alleging the company knew or should have known about this risk and failed to adequately warn patients and prescribing physicians.
What Is an Intracranial Meningioma?
A meningioma is a tumor that arises from the meninges — the three layers of membrane that surround and protect the brain and spinal cord. While many meningiomas are classified as benign, they can cause serious and life-altering symptoms depending on their size and location. Even a non-cancerous meningioma can compress brain tissue, nerves, and blood vessels, leading to significant neurological harm.
Common Symptoms of Intracranial Meningiomas
Persistent Headaches
Often the first and most common symptom, headaches caused by meningiomas tend to worsen over time and may be accompanied by nausea or vomiting.
Vision Changes
Tumors near the optic nerve or visual cortex can cause blurred vision, double vision, or progressive vision loss.
Hearing Loss or Tinnitus
Meningiomas near the auditory nerve can cause hearing loss, ringing in the ears, or balance problems.
Seizures
Pressure on brain tissue from a growing tumor can trigger new-onset seizures in patients with no prior seizure history.
Memory & Cognitive Changes
Depending on location, meningiomas can affect memory, concentration, personality, and executive function.
Weakness or Numbness
Tumors pressing on motor or sensory areas of the brain can cause weakness, numbness, or paralysis on one side of the body.
Who May Qualify for a Claim?
You may have a claim against Pfizer if you used Depo-Provera for an extended period — generally one year or more — and were subsequently diagnosed with an intracranial meningioma. Claims may also be available to women who required surgery, radiation, or other treatment for a meningioma that developed during or after Depo-Provera use.
Our attorneys are currently investigating claims on behalf of women who have been diagnosed with meningiomas following Depo-Provera use. The statute of limitations for these claims varies by state, so it is important to speak with an attorney as soon as possible.
Frightening Research
The legal actions are largely based on recent studies that have identified a significant association between Depo-Provera and an increased risk of meningiomas. A study published in The BMJ in March 2024 found that women injected with medroxyprogesterone acetate, the active ingredient in Depo-Provera, had a 5 to 6-fold higher risk of developing a meningioma. This risk increased with one year or more of use. These findings have prompted further investigations and legal scrutiny regarding the safety of the contraceptive.
These lawsuits are part of a growing number of cases filed across the United States. The plaintiffs allege that Pfizer failed to adequately warn users about the potential risks associated with prolonged use of Depo-Provera. In response to the increasing number of cases, these lawsuits have been centralized into a Multidistrict Litigation (MDL), aiming to streamline the legal process and handle the claims more efficiently.
Pfizer's Response
Pfizer has responded to these allegations by stating that Depo-Provera has been an FDA-approved medication for more than 30 years and has been a safe and effective treatment option for millions of patients during that time. The company has expressed its intent to vigorously defend against these lawsuits. However, the growing body of research linking Depo-Provera to an increased risk of meningiomas, along with the rising number of legal claims, has raised significant concerns about the safety of the contraceptive and the adequacy of the warnings provided to users.
