Pfizer sued in US over contraceptive that women say caused brain tumours

Class action lawsuit alleges company failed to warn about risks of using contraceptive injection Depo-Provera

The drugmaker Pfizer faces a US lawsuit brought on behalf of women who developed brain tumours, which they say are linked to their use of the company's contraceptive injection Depo-Provera.

The class action lawsuit alleges that the US pharmaceutical company failed to warn women and doctors about the increased risk of developing an intracranial meningioma if Depo-Provera, a quarterly injection, is used for more than a year.
