UK law firms are exploring legal action against Pfizer on behalf of women who developed brain tumours after using the contraceptive injection Depo-Provera. The drug, a high-dose synthetic progesterone administered every three months, is used by approximately 3.1% of UK women aged 15-49 and 74 million women worldwide.
Multiple studies have shown that Depo-Provera users have a significantly higher relative risk of developing meningiomas, benign brain tumours that can cause seizures, blindness, hearing loss, headaches and memory problems. Although the overall risk remains low, the potential consequences are severe.
Law firms including Austen Hays, Fletchers and Leigh Day are investigating claims. Austen Hays partner Chaya Hanoomanjee said: “We have been approached by at least 30 women who have developed meningiomas following prolonged use of Depo-Provera. Their lives have been considerably impacted due to having brain tumours, with consequences such as loss of vision and, in one case, a woman having to terminate her pregnancy.”
Leigh Day partner Jill Paterson added: “We know the devastating impact meningiomas can have on women’s lives and are assessing the strength of any potential case.” The UK developments come as thousands of women in the US are suing Pfizer, with the first trial scheduled for December. The US claimants argue Pfizer knew of the meningioma risk since at least 2015 but failed to warn patients or regulators.
Pfizer has not admitted liability and is contesting the litigation. Women affected have described life-changing symptoms. Claire Buck, 47, from Surrey, who took Depo-Provera for several years, required brain surgery and a metal plate in her head. She said: “I nearly died. I’m lucky to be here.” Another woman, Sandra Somarakis, who used the jab for 15 years, said: “Women shouldn’t have to live with what I’ve gone through. There has to be consequences.”
