FDA keeping a watchful eye on studies on dangers of Yaz
The Food and Drug Administration (FDA) says it will keep a watchful eye on studies comparing drospirenone-containing birth control pills with levonorgestrel-containing oral contraceptives to determine if one is more dangerous to users. Two recent studies published in the British Medical Journal found pills with drospirenone were two to three times more likely to cause blood clots in women who used them.
Birth control pills with the hormone drospirenone include Bayer’s Yaz, Yasmin, Beyaz and Safyral, as well as generics Ocella, Gianvi, Loryna, Syeda, and Zarah. The FDA says it hopes to have data later this summer from an 800,000-person study it commissioned to examine the risks.
