Depo-Provera, a widely used birth control injection, is now at the center of growing medical and legal concern. Recent studies from 2023 to 2025 link prolonged Depo-Provera use to serious health risks, including bone mineral density loss, meningioma brain tumors, and other potentially permanent injuries. As evidence builds, lawsuits claim that Pfizer failed to properly warn users of these dangers.
In this blog, we explain the risks of Depo-Provera permanent damage, review the latest medical studies, outline 2025 lawsuit updates, and discuss how working with an experienced mass tort lawyer at Rueb Stoller Daniel can help you seek justice and compensation.
What is Depo-Provera?
Depo-Provera is a widely used injectable contraceptive that contains the hormone medroxyprogesterone acetate. It is often referred to as the birth control shot and is given once every three months. Many people choose this option because it does not require daily use, but research shows it carries risks that can lead to depo-provera permanent damage.
How Depo-Provera Works
Depo-Provera prevents pregnancy by stopping ovulation. It also thickens cervical mucus, which makes it harder for sperm to reach the egg. The drug alters the uterine lining, reducing the chance of implantation. This method is considered effective, but long-term use has raised serious concerns in medical studies.
Depo-Provera Injections and Forms
The most common form is the Depo-Provera injection given into the muscle every 12 weeks. Another version, known as Depo-SubQ Provera 104, is injected under the skin. Both contain depot medroxyprogesterone acetate, but they are delivered in slightly different ways.
Depo-Provera Use in the United States
According to CDC data, millions of women in the United States have used the Depo Shot as their main form of birth control. While many appreciate the convenience, prolonged Depo-Provera use has been linked to bone density loss, meningioma brain tumors, and other permanent health problems.
Known Side Effects vs. Suspected Permanent Damage
Depo-Provera has both short-term side effects and long-term risks that may cause permanent damage. Understanding the difference helps users see why Depo-Provera lawsuits allege serious health consequences.
Short-Term Side Effects
Many users experience side effects within the first months of taking Depo-Provera injections. Common issues include irregular bleeding, weight gain, headaches, and mood changes. These effects often lessen over time or after stopping use.
Long-Term Health Concerns
Medical studies show that prolonged Depo-Provera use can lead to lasting harm. The most documented concern is bone mineral density loss, which may not fully recover even after discontinuing the birth control shot. This condition increases the risk of fractures and osteoporosis.
Potentially Permanent Damage
More recent research links Depo-Provera to intracranial meningiomas, a type of brain tumor. Women who developed meningioma brain tumors after prolonged use are now pursuing legal action. Other risks include blood clots such as deep vein thrombosis, as well as possible connections to breast cancer and uterine fibroids.
What the Latest Studies Are Revealing (2023–2025)
Recent research sharpens our understanding of risks tied to depo-provera permanent damage. These findings highlight concerns over intracranial meningioma, bone loss, and related health dangers.
Link Between Depo-Provera and Brain Tumors
Studies show that women who used medroxyprogesterone acetate for one year or longer faced a higher risk of developing intracranial meningioma compared to non-users. Other research in the United States confirmed that prolonged Depo-Provera use increases the likelihood of brain tumors.
Further data from insurance records revealed that patients exposed to Depo-Provera for more than three years faced a significantly higher chance of developing meningioma. A 2025 analysis confirmed that using Depo-Provera for over one year raised the risk compared to combined oral contraceptive users.
Alarming Recent Safety Trends
Adverse event reports have shown a rapid increase. In 2023, only a few meningioma cases were logged. By mid-2025, the number had climbed into the hundreds, with patients reporting serious brain tumor outcomes after taking Depo-Provera injections.
Broader Health Risks Beyond Tumors
Long-term studies also link prolonged Depo-Provera use with permanent bone mineral density loss. These declines may not fully reverse after stopping the birth control shot, raising the risk of fractures and osteoporosis.
Depo-Provera Lawsuits and 2025 Litigation Updates
The growing number of claims filed against Pfizer highlight the link between Depo-Provera permanent damage and serious health risks. Courts across the United States are now hearing cases that focus on bone density loss, brain tumors, and other long-term injuries.
Current Depo-Provera Lawsuit Landscape
Thousands of women have filed Depo-Provera lawsuits alleging that Pfizer failed to warn about the risks tied to prolonged Depo-Provera use. Claims include defective design, failure to warn, and negligent misrepresentation. The lawsuits argue that patients were not properly informed of the risks of bone mineral density loss, intracranial meningioma, and other severe conditions.
2025 Litigation Updates
In 2025, the cases were consolidated into multidistrict litigation (MDL). Federal judges have allowed claims involving meningioma brain tumors and permanent bone damage to move forward. Early hearings are focused on the admissibility of expert testimony, with courts finding that medical evidence of harm is strong enough to proceed. Bellwether trials are now scheduled for late 2025, which will set the stage for possible global settlements.
Types of Injuries at the Center of Lawsuits
The depo shot lawsuits focus on two primary areas of harm. The first involves intracranial meningioma brain tumors, which can cause permanent neurological damage. The second involves bone mineral density loss, which can result in fractures and long-term osteoporosis. Other claims include blood clots, breast cancer, and uterine fibroids.
Legal Rights for Depo-Provera Users
Anyone who developed serious health issues after using Depo-Provera injections may be eligible to file a Depo-Provera lawsuit. A mass tort attorney can help victims pursue compensation for medical expenses, lost wages, and pain and suffering. Families who lost loved ones due to complications may also qualify for legal action.
What To Do If You Suspect Harm from Depo-Provera
If you believe you have suffered depo-provera permanent damage, it is important to take clear steps to protect both your health and your legal rights.
Recognize the Warning Signs
Be aware of symptoms that may point to serious harm from prolonged Depo-Provera use. Warning signs include persistent headaches, changes in vision, seizures, or weakness that may signal a meningioma brain tumor. Bone pain, frequent fractures, or loss of height may indicate bone mineral density loss. Blood clots, sudden chest pain, or breathing issues should also be treated as emergencies.
Seek Immediate Medical Treatment
Medical evaluation is critical if you are experiencing these symptoms. Imaging tests can detect intracranial meningiomas, and bone scans can measure bone density loss. Document every medical visit and request copies of your records, including proof of Depo-Provera injections. These records are essential for both treatment and legal claims.
Preserve Documentation
Keep a detailed file of your prescription history, injection dates, and any hospital or doctor visits linked to side effects. Include receipts, test results, and notes from healthcare providers. This documentation will strengthen your ability to file a Depo-Provera lawsuit if permanent damage is confirmed.
