Depo-Provera Lawsuit
Recent research into long-acting injectable contraceptives like Depo-Provera, manufactured by Pfizer, has raised concerns over the drug’s link to an increased risk of brain or spine tumors known as meningiomas.
About the Lawsuit
What Is Depo-Provera?
Depo-Provera is a hormonal contraceptive injection intended to provide long-term birth control for women. Though widely promoted as a convenient and effective form of contraception, troubling side effects and long-term health risks have led to a growing number of lawsuits against the drug’s manufacturer, Pfizer.
A Long-Acting Injectable Contraceptive
Depo-Provera is a brand name for the injectable form of medroxyprogesterone acetate, a synthetic hormone that also goes by the name depot medroxyprogesterone acetate. It is administered as a shot every three months and has been marketed as a safe, long-acting form of birth control. However, serious questions have been raised about the drug’s safety, particularly for long-term users.
Depo-Provera works by suppressing ovulation (stopping the ovaries from releasing an egg), thickening cervical mucus, and thinning the uterine lining to prevent pregnancy. It largely tries to keep sperm from reaching the egg. It has been approved by the FDA for use since the early 1990s, but concerns about its risks have grown significantly in recent years.
Why Is There a Depo-Provera Lawsuit?
The lawsuits surrounding Depo-Provera focus primarily on claims that the drug’s manufacturer failed to adequately warn users about serious risks, including brain tumors or meningiomas. Plaintiffs allege that if they had been properly warned of these risks, they would have chosen a different method of contraception.
In 2004, the FDA required a “black box” warning for Depo-Provera to address the risk of significant bone density loss. However, the warning failed to mention anything regarding the possibility of developing a brain tumor. The FDA warning also states that the medicine shouldn’t be used for longer than two years.
Depo-Provera & Meningiomas
After using Depo-Provera, many women were later diagnosed with meningiomas — tumors of the brain or spine — complications they claim were never adequately disclosed. According to the Mayo Clinic, other reported side effects of Depo-Provera include:
- Belly pain
- Bloating
- Less interest in sex
- Depression
- Dizziness
- Headaches
- Irregular periods and breakthrough bleeding
- Nervousness
- Weakness and tiredness
- Weight gain
