According to a review by Health Canada, women taking Bayer’s popular birth control pills, Yaz and Yasmin, may be up to three times more likely to develop a serious blood clot, compared to those taking older-generation oral contraceptives.
On Monday, Health Canada announced it had completed a safety review of drospirenone-containing birth control pills. As part of its release, Health Canada said that, “Overall, the body of current evidence suggests that the risk of blood clots in 1.5 to 3 times higher with oral contraceptives that contain drospirenone relative to those that contain levonorgestrel, a different hormone.”
While the labels for these drospirenone-containging drugs have been updated to reflect the new information regarding the increased risk for blood clots, the U.S. Food and Drug Administration’s reproductive health drugs advisory committee will still meet on Thursday in order to further discuss the safety and efficacy of these products.
