A study has linked Depo Provera to a fivefold increase in meningioma risk after just four doses.
Depo-Provera is a hormonal birth control injection that contains medroxyprogesterone acetate, a synthetic form of the hormone progesterone. It was approved by the U.S. Food and Drug Administration (FDA) in 1992 and is advertised to prevent pregnancy by inhibiting ovulation, thickening cervical mucus to block sperm, and thinning the uterine lining to prevent a fertilized egg from implanting.
While Depo-Provera has been advertised for years as a safe and convenient form of birth control, a growing number of adverse events have been reported to the U.S. Food and Drug Administration in recent decades, and new medical research indicates that women taking Depo-Provera for more than one year face a fivefold increased risk of developing meningioma brain tumors.
Although it appears that Pfizer knew or should have known about this risk, warnings about the risk of meningioma or other forms of brain tumors as a potential side effect of Depo-Provera have not been provided to women or the medical community.
Our firm is investigating claims for individuals who have suffered Depo-Provera brain tumor side effects that could have been avoided if adequate warnings and information had been provided about the risk.

Other Side Effects
"We believe that Pfizer, the manufacturer of Depo-Provera, has been aware of these risks for over two decades but failed to warn women and their doctors. If you had known about these risks, would you have chosen another form of birth control?"
