Depo Provera Lawsuit Overview
On this page, we’ll discuss the Depo Provera Lawsuit for Brain Tumors, the role of a lawyer in determining eligibility and seeking compensation in Depo Provera Lawsuits, information on the scientific findings concerning the development of brain tumors related to Depo Provera usage, and much more.
Depo-Provera Contraceptive Injection Linked to Brain Tumors
The Depo-Provera contraceptive injection has been linked to an increased risk of developing intracranial meningiomas, a type of brain tumor.
Recent studies have shown that women who use Depo-Provera for more than 12 months face a significantly higher risk of developing these tumors, which, although typically benign, can lead to serious and potentially life threatening health issues if left untreated.
Symptoms of meningiomas include headaches, seizures, and vision problems, often requiring surgery for removal.
Researchers have highlighted that the risk of meningiomas rises with prolonged use of Depo-Provera, prompting concerns about the drug’s safety for long-term users.
Despite these risks, Pfizer, the manufacturer of Depo-Provera, has only recently begun updating warning labels to reflect the potential danger.
Warning labels in Europe and the United Kingdom have been updated to include the risk of brain tumors, but warning labels in the United States have not yet been changed.
Legal action is being taken by individuals who have suffered from these complications, with lawsuits alleging that Pfizer Inc. failed to adequately warn users of the risks.
If you or a loved one developed brain tumors after taking Depo Provera injections, you may be eligible to file a Depo Provera Lawsuit and seek compensation.

It is the responsibility of pharmaceutical companies to ensure that their products are safe for consumers and to provide adequate warnings about any potential risks associated with their use.
In the case of Depo-Provera, plaintiffs in ongoing lawsuits allege that Pfizer failed to properly warn users about the increased risk of developing brain tumors after prolonged use.
The Depo-Provera Shot Lawsuit seeks compensation for medical expenses, pain and suffering, and other damages resulting from the serious side effects linked to the contraceptive injection.

May 19, 2025: Depo-Provera Meningioma Study Adds Critical Evidence to Ongoing Lawsuits
A February 2025 study from the University of British Columbia offers new, peer-reviewed evidence linking long-term use of Depo-Provera to brain tumors.
Using U.S. insurance claims data, researchers compared Depo-Provera users to women taking oral contraceptives and found a 3.5-fold increased risk of meningioma among those using the injectable birth control for more than a year.
The study also showed elevated risks for continued use: 2.95 times higher after two years, 3.17 after three, and 3.50 after four years.
Unlike previous studies, this analysis used a robust control group and accounted for tumor latency and other variables that could skew results.
The researchers cited Depo-Provera’s effect on progesterone receptors—also frequently overexpressed in meningiomas—as a likely biological explanation.
Despite warnings added to Depo-Provera labeling in Europe, the FDA has yet to issue similar guidance in the U.S.
This new research has been cited by plaintiffs in the ongoing Depo-Provera MDL, where women across the country are pursuing claims that Pfizer failed to warn about the potential for brain tumor development.
With bellwether trials approaching and over a million women using the drug each year, this study could serve as a key piece of scientific evidence in holding the manufacturer accountable.

What is Depo Provera and How Does it Work?
Depo-Provera is a widely used injectable contraceptive containing the hormone medroxyprogesterone acetate, a synthetic form of the hormone progestin.
This hormone prevents pregnancy by inhibiting ovulation and thickening cervical mucus, meaning it stops the ovaries from releasing eggs and makes it more difficult for sperm to travel through the cervix and reach an egg.
Depo Provera is administered as a birth control shot every three months.
This makes Depo Provera a popular choice for women who who want long-term but reversible birth control without taking daily pills.
There are two formulations of Depo-Provera, including Depo-SubQ Provera 104, a lower-dose version that is injected just under the skin rather than into the muscle.
Both versions are effective at preventing pregnancy and are sometimes prescribed to manage conditions like endometriosis.
However, while Depo-Provera offers convenience and effectiveness, its long-term use has been associated with potentially serious side effects and health risks, such as bone density loss and an increased risk of developing brain tumors.
It’s essential to discuss these potential risks with a healthcare provider when considering Depo-Provera as a contraceptive method.
Who is the Maker of Depo Provera?
Depo-Provera is manufactured by Pfizer Inc., one of the largest pharmaceutical companies in the world.
Depo Provera was initially approved by the FDA in 1992 for use as a contraceptive injection.
Pfizer is also responsible for distributing the lower-dose version, Depo-SubQ Provera 104.
Health Risks Associated with Taking Depo Provera
Depo-Provera users face several potential health risks, especially when the contraceptive is used long-term.
One of the most serious concerns is the significant loss of bone mineral density, which can lead to osteoporosis and increase the risk of fractures.
Studies have also linked prolonged use of Depo-Provera to an elevated risk of developing intracranial meningiomas, a type of brain tumor that can cause severe symptoms such as headaches, vision issues, and seizures.
Other reported side effects include weight gain, mood changes, and an increased risk of blood clots, which can lead to life-threatening conditions like pulmonary embolism or stroke.
Given these risks, it is crucial for users to regularly consult with their healthcare provider to evaluate whether the benefits of Depo-Provera outweigh the potential health complications.
Depo Provera Brain Tumor Risk (Intracranial Meningioma)
Recent studies published in The British Medical Journal (BMJ) and other peer-reviewed journals have identified a significant link between long-term use of Depo-Provera and the development of intracranial meningiomas, a type of brain tumor.
While these tumors are typically benign, they can cause severe complications such as headaches, vision issues, and seizures if left untreated.
Meningiomas are typically benign but can cause serious complications if left untreated, including severe headaches, vision issues, and seizures.
The risk of developing these tumors increases with prolonged use of Depo-Provera, particularly in women who have been using the contraceptive for two or more years.
Key scientific findings include:
- 5.6-fold increased risk to develop brain tumors: Women who used Depo-Provera for over 12 months were found to have a 5.6-fold higher risk of developing intracranial meningiomas.
- Meningiomas account for 40% of primary brain tumors: While often benign, these tumors can grow large enough to require surgical removal, posing additional health risks.
- Prolonged hormone use: The risk is particularly heightened for long-term users, as studies have shown that extended exposure to progestogens, including medroxyprogesterone acetate (Depo-Provera), leads to a higher incidence of meningiomas.
- Symptoms and treatment: Common symptoms include headaches, seizures, and neurological changes, with treatment options ranging from surgery to radiation therapy depending on tumor size and location.
- Other contraceptives: The same risk was not found with other types of hormonal contraceptives like levonorgestrel intrauterine systems, which suggests the risk may be specific to progestogens like medroxyprogesterone acetate.
These findings are crucial for anyone considering long-term use of Depo-Provera, as the potential for brain tumors is a serious concern.
Does the Depo Provera Warning Label Include Brain Tumor Risk?
As of 2024, the U.S. label for Depo-Provera does not include a warning about the increased risk of brain tumors, such as intracranial meningiomas.
While the European Union and the United Kingdom have updated their labels to reflect this risk, the U.S. version has not yet incorporated this information.
Pfizer has only indicated that it plans to update the label in the future.
An Overview of Intracranial Meningiomas (Depo-Provera Brain Tumors)
Intracranial meningiomas are tumors that form in the meninges, the protective layers surrounding the brain and spinal cord.
These tumors are typically slow-growing and are classified as benign in most cases, meaning they are not cancerous.
However, their location in the brain can still cause serious complications, as they can press against brain structures and nerves, leading to neurological symptoms.
Intracranial meningiomas account for approximately 40% of all primary brain tumors, making them one of the most common types.
While the exact cause of meningiomas is not always clear, certain factors such as prolonged use of hormone therapies like Depo-Provera have been linked to an increased risk of developing these tumors.
Symptoms of Depo Provera Brain Tumors
Women who develop intracranial meningiomas linked to Depo-Provera usage often experience a variety of symptoms based on the size and location of the tumor.
These symptoms may range from mild to severe and can worsen if the tumor is left untreated.
Early detection is critical to managing the condition, as treatment may prevent further complications.
Common symptoms of Depo-Provera brain tumors include:
- Persistent headaches: Often caused by the tumor pressing on surrounding tissues.
- Vision changes: Blurred or double vision if the tumor affects optic nerves or vision-related brain regions.
- Seizures: A result of the tumor’s pressure on brain areas that control electrical activity.
- Muscle weakness or numbness: Particularly in the limbs if motor areas of the brain are affected.
- Cognitive or personality changes: Memory loss, confusion, or behavioral shifts due to the tumor’s impact on brain function.
Diagnosis of Intracranial Meningiomas
Diagnosing intracranial meningiomas typically begins with a detailed medical history and physical examination, particularly if symptoms like headaches, vision changes, or seizures are present.
The first step in confirming the presence of a brain tumor is usually imaging tests, such as a magnetic resonance imaging (MRI) scan, which provides detailed images of the brain and can reveal the size and location of the tumor.
A computed tomography (CT) scan may also be used, especially if MRI is unavailable or further confirmation is needed.
In some cases, a biopsy may be performed, where a small sample of the tumor is taken for examination under a microscope to determine whether it is benign or malignant.
Blood tests may also be conducted to rule out other conditions that could be causing similar symptoms.
Doctors often use these diagnostic tools to assess the tumor’s growth rate and its potential impact on surrounding brain structures.
Once a diagnosis is confirmed, a treatment plan is developed based on the tumor’s size, location, and the patient’s overall health.
Medical Treatment for Intracranial Meningiomas
Intracranial meningiomas, though often benign, can still pose significant health risks depending on their size and location in the brain.
Treatment for these tumors largely depends on their growth rate, symptoms, and potential impact on brain function.
Smaller, asymptomatic tumors may simply be monitored through regular imaging tests, while larger or symptomatic meningiomas usually require more aggressive treatment.
Surgical removal is often the primary treatment for meningiomas that cause symptoms or grow rapidly.
Radiation therapy may be used either after surgery to eliminate remaining tumor cells or as a primary treatment if surgery isn’t feasible.
Some patients may also benefit from newer, targeted therapies, though these are generally still under investigation.
Common treatment options for intracranial meningiomas include:
- Observation: Regular MRIs or CT scans to monitor tumor growth for smaller, asymptomatic tumors.
- Surgery: Complete or partial removal of the tumor, often recommended for larger or symptomatic meningiomas.
- Radiation therapy: Used post-surgery or as a primary treatment, especially when the tumor is inoperable.
- Stereotactic radiosurgery: A form of targeted radiation that precisely delivers high doses to the tumor while sparing surrounding brain tissue.
- Chemotherapy: Rarely used, but may be considered in more aggressive cases or where other treatments are ineffective.
- Medications for symptom management: Anti-seizure medications or corticosteroids may be prescribed to manage symptoms like seizures and brain swelling.
Treatment plans are tailored to each patient’s specific needs, and the potential risks of each option are carefully weighed against the benefits.
Complications and Long-Term Effects of Intracranial Meningiomas
Although most intracranial meningiomas are benign, their location in the brain can lead to serious complications if left untreated.
The long-term effects depend on the size and location of the tumor and the treatment method used, which can result in permanent damage to brain functions.
Some patients may experience lasting neurological impairments, such as memory issues, difficulty with motor skills, or persistent headaches.
Treatment options like surgery or radiation therapy can carry risks of further complications, including infections, brain swelling, or cognitive changes.
Common complications and long-term effects include:
- Cognitive impairment: Memory loss or difficulty concentrating, particularly if the tumor affects cognitive regions of the brain.
- Motor function issues: Weakness, numbness, or coordination problems, often related to tumor pressure on motor regions.
- Seizures: Some patients may continue to experience seizures, even after tumor removal.
- Vision loss: If the tumor is near the optic nerves or visual pathways, permanent vision changes or loss can occur.
- Chronic headaches: Persistent headaches can result from tumor growth or post-treatment recovery.
- Hormonal imbalances: Tumors near the pituitary gland can affect hormone production, leading to long-term health issues.
- Emotional and personality changes: Some patients may experience shifts in mood or behavior due to the tumor’s impact on brain function.
Addressing these complications early through proper diagnosis and treatment is essential to managing long-term effects.
