Papers published in the British Medical Journal show newer pills with the synthetic hormone drospirenone, including Yaz and Yasmin, have a higher chance of causing blood clots. One study found women who use pills with drospirenone have twice the risk of getting a blood clot, and a second put that rate at 2.7 times the risk. The occurrence is still relatively low, 30.8 blood clots per 100,000 women at its highest.
Yaz has become the nation's best-selling pill. Women who use it report better moods and decreased symptoms of PMDD, although the producer Bayer was forced to run ads in 2009 correcting over-promised benefits like a cure for acne and premenstrual syndrome. Of course, every woman's experience is different. So I'm curious, have you tried these new-generation pills? If so, share your experience in the comments.
