An illustration picture shows a woman holding a birth control pill at her home in Nice January 3, 2013. French health regulators are studying limiting the use of contraceptive pills that carry health risks and will stop reimbursing prescription costs of some types from March, after a woman sued drugmaker Bayer over alleged side-effects. An inquiry launched this week by the ANSM health regulator will review prescription practices by doctors, whom it says may be over-prescribing higher-risk third and fourth-generation pills.
