Blood Clots With Some Birth Control Pills
August 30, 2012
Birth control pills that contain drospirenone may be associated with a higher risk of blood clots than other progestin-containing pills. FDA bases this conclusion on its review of recent studies on the risk of blood clots in women taking drospirenone-containing birth control pills.
Drospirenone is a synthetic version of the female hormone progesterone, also referred to as a progestin. FDA is adding information about the studies to the labels of drospirenone-containing birth control pills, which include:
- Drospirenone and ethinyl estradiol
Risk: The revised drug labels will state that some studies reported as high as a three-fold increase in the risk of blood clots for drospirenone-containing products when compared to products containing levonorgestrel or some other progestins, but other studies found no additional risk of blood clots with drospirenone-containing products.
Recommendation: Women should talk to their health care professional about their risk for blood clots before deciding which birth control method to use.
