Food and Drug Administration to review YAZ

The Food and Drug Administration will review birth control pills made by the Bayer company, over concerns they may cause more blood clots than competing contraceptives.

Two reports in the British Medical journal found up to a three-fold greater risk of blood clots in women taking Yaz birth control.

Since this contradicts early research data, the FDA will review that study. They expect to have the results later this summer.

In the meantime, patients should watch for blood clot symptoms including leg or chest pains.
