The Food and Drug Administration has released a new study linking several new birth control pills, including the drug Yaz, to an increased risk of dangerous, even life-threatening blood clots. The Associated Press reports:
A new study released by the Food and Drug Administration reviewed the medical history of more than 800,000 women taking different forms of birth control between 2001 and 2007. On average, woman taking Yaz had significantly higher rates of blood clots than women taking older birth control drugs.
The agency also reports higher complications in women using the Ortho Evra patch from Johnson & Johnson and the Nuvaring vaginal ring from Merck & Co. Inc.
The FDA will hold a public meeting in December to discuss the findings further.
