A series of studies have linked the injectable birth control medroxyprogesterone acetate (MPA), sold under the brand name Depo-Provera, to a significantly increased risk of developing meningiomas – a type of tumor found in the membrane surrounding the brain. Research published in the Expert Opinion on Drug Safety journal and the British Medical Journal shows that women using this injection had a much higher risk of developing these tumors compared to those using oral contraceptives. One study found a fivefold increase in risk after a year of use, while another noted a 53 percent higher chance among women who received the injection.
As a result of these findings, multiple lawsuits – including a class action and several individual suits – have been filed against Pfizer, the drug’s manufacturer. Plaintiffs say they suffered severe health consequences, including strokes, seizures, and cognitive impairments. Attorneys representing the plaintiffs argue that the risks of Depo-Provera have not been adequately communicated to users.
