The U.S. Food and Drug Administration (FDA) is informing the public about new information1,2 that is being assessed as part of FDA's ongoing safety review of birth control pills that contain drospirenone. This review will further evaluate the risk of blood clots in women who use these products.
Drospirenone is a type of female sex hormone called a progestin. Most birth control pills contain two types of hormones--estrogen and progestin. Birth control pills work by preventing the release of eggs from the ovaries (ovulation) and changing the cervical mucus and the lining of the uterus to prevent pregnancy.
A list of birth control pills that contain drospirenone is available here.
