What is the Depo-Provera Shot and How Does it Work?
Depo-Provera, the brand name for medroxyprogesterone acetate, is a popular contraceptive known as the birth control shot. It is an injectable form of birth control administered every three months, typically in the arm or buttock. This method offers a long-lasting and highly effective form of contraception, with over 99% effectiveness when taken as scheduled, eliminating the need for daily attention. It is administered every 12 weeks and works in three main ways to prevent pregnancy:
- Prevents Ovulation: The shot stops the ovaries from releasing eggs.
- Thickens Cervical Mucus: It thickens the mucus in the cervix, making it harder for sperm to reach the egg.
- Thins the Uterine Lining: Depo-Provera thins the lining of the uterus, which prevents the implantation of a fertilized egg.
In addition to contraception, Depo-Provera is sometimes prescribed for other gynecological conditions such as endometriosis, where it helps manage symptoms by reducing painful menstrual cycles and regulating hormones.
Common Uses of Depo-Provera: Depo-Provera is used for several purposes, though it is primarily prescribed for:
- Contraception (Birth Control): Depo-Provera is widely used as a long-term contraceptive method.
- Endometriosis-Associated Pain: It helps alleviate the pain associated with endometriosis by suppressing the growth of uterine tissue.
- Abnormal Uterine Bleeding: Depo-Provera can be used to manage heavy or irregular menstrual bleeding.
By using this method of birth control, many women find a convenient way to avoid daily or weekly contraceptive methods, while also addressing specific health issues such as menstrual irregularities or endometriosis. However, like any medication, it comes with potential side effects and risks, so it’s important to discuss with a healthcare provider to understand if Depo-Provera is the right choice for you.
Injuries Related to Depo-Provera
While Depo-Provera effectively prevents pregnancy, it has been linked to several health risks:
- Brain Tumors (Meningiomas): A key focus of the lawsuits is the connection between long-term Depo-Provera use and the development of meningiomas, a type of tumor that affects the protective membranes around the brain and spinal cord. These tumors, though often benign, can still have severe health consequences, including vision and memory loss.
- Bone Density Loss: Long-term use of Depo-Provera has been associated with significant bone density reduction, increasing the risk of osteoporosis.
- Irregular Bleeding, Weight Gain, and Headaches: Many users report side effects like changes in menstrual cycles, weight gain, and frequent headaches.

About Meningioma
A meningioma is a type of brain tumor that forms in the meninges, the protective membranes that cover the brain and spinal cord. Meningiomas are the most common type of brain tumor, accounting for approximately 40% of all brain tumors diagnosed.
While most meningiomas are benign (non-cancerous), a small percentage can be malignant. Meningiomas tend to grow slowly and can remain undiagnosed for years, as symptoms may not appear immediately.
Meningiomas are classified into three grades based on their growth patterns:
- Grade I: The most common type, these tumors are non-cancerous and grow very slowly, making up about 80% of meningioma cases.
- Grade II: These tumors are also non-cancerous but grow more quickly and are more likely to recur, which can make treatment more challenging.
- Grade III: Malignant meningiomas are rare, accounting for less than 2% of cases. They grow aggressively and may spread to other parts of the brain or body.
Meningiomas are often discovered incidentally during MRI or CT scans, especially in patients who show no symptoms. In cases where the tumor is asymptomatic, doctors may recommend regular monitoring rather than immediate intervention. However, if symptoms are present, treatment usually involves surgery to remove the tumor. The goal is to remove the tumor and surrounding tissue to prevent recurrence. Depending on the location and size of the tumor, surgery can be complex and may be followed by radiation therapy or chemotherapy if complete removal isn’t possible.
Given the invasive nature of treatment and the potential for long-term complications, meningioma lawsuits, especially those tied to medications like Depo-Provera, may result in significant settlement payouts. All three grades of meningiomas are valid personal injury claims, as the impact on a patient’s life can be profound, even in non-cancerous cases.
New Research Links Depo-Provera to Brain Tumors in Women
- A 2024 study published in the British Medical Journal revealed that prolonged use of medroxyprogesterone acetate, the active ingredient in Depo-Provera, significantly increases the risk of developing intracranial meningiomas—a type of brain tumor—by 5.6 times. This study analyzed data from 18,061 women who had undergone surgery for these tumors, which form in the meninges (the membranes surrounding the brain and spinal cord). While meningiomas are usually benign (non-cancerous), the risk of surgery and other complications can make their presence concerning.
- The research highlights that the risk increases with higher doses or long-term use of progestin-based contraceptives like Depo-Provera. The hormone progestin, found in Depo-Provera, may encourage tumor growth through its interaction with progesterone receptors. However, in some cases, discontinuing Depo-Provera has led to tumor stabilization or even regression, suggesting that the effects may be reversible if the medication is stopped.
Depo-Provera Manufacturer: Pfizer
- Pfizer, Inc. has been manufacturing Depo-Provera since it acquired the rights through a merger with Pharmacia in 2003. As the company responsible for ensuring the drug’s safety, Pfizer has marketed Depo-Provera globally in various formulations, including the standard contraceptive injection and a lower-dose version (Depo-SubQ Provera 104).
- While Depo-Provera has been widely used as an effective contraceptive, Pfizer has faced multiple lawsuits related to the drug, including claims regarding bone density loss and, more recently, the potential link to meningiomas. The company continues to navigate these legal challenges while distributing Depo-Provera globally.
