Warning: Birth Control Pills That Contain Drospirenone May Cause Serious Bloodclots

One of the benefits of being in my school’s peer sexual health education group is that we get constant updates on birth control safety via our supervisor from the FDA listserv. Recently I received an email containing the following information:

“Two recently published studies reported a greater risk of blood clots for women taking birth control pills containing drospirenone as compared to the risk in women taking birth control pills containing another progestin known as levonorgestrel.

Previously published studies have also addressed the risk of blood clots in women using birth control pills containing drospirenone. These studies had conflicting findings–two postmarketing studies required by the FDA or European regulatory agencies did not report any difference in the risk of blood clots between drospirenone-containing products and products containing levonorgestrel or other progestins.4,5 Two other publications in 2009, however, reported that the risk of blood clots is higher in women using drospirenone-containing products than in women who use levonorgestrel-containing products.”

Here is a list of birth control pills containing drospirenone:

  • Yaz (generics Gianvi and Loryna)
  • Yasmin (generics Ocella, Syeda, and Zarah)
  • Beyaz
  • Safyral.

You can read the full report on the FDA Website.
