The F.D.A. is conducting a review of certain birth control bills that contain the hormone drospirenone. The hormone is found in Bayer’s Yaz, Yasmin, Beyaz and Safyral. While all birth control pills pose a rik of blood clots, certain studies have suggested that Bayer’s birth control pills pose a greater risk of blood clots. Two recent reports in the British Medical Journal found a two-fold to threefold greater risk of blood clots in women taking birth control pills like Bayer’s Yaz. The F.D.A. ‘s current review involves an 800,000 person study. The sale of Yaz family of products in 2010 represented 3.3 percent of Bayer’s annual revenue. The lawyers at Sabatini & Associates, LLC currently represent women injured by Yaz and Yasmin and is accepting new cases.
