Study: New birth control drugs increase risk of blood clots

(CNN) - Some newer forms of birth control may raise your risk of getting blood clots, according to a new study by the Food and Drug Administration.

The study looked at the medical histories of more than 800,000 American women who were on birth control between January 2001 and December 2007.

Women who used newer oral contraceptives were at a higher risk of developing potentially dangerous blood clots, according to the study's findings.  

Women who used Bayer's Yasmin, Johnson & Johnson's Ortho Evra patch and Merck's Nuvaring were among those with the highest instances of blood clots.
