Bayer adds new information about blood clot risk to Yaz, Yasmin labels
Bayer HealthCare has added new information on the labels of its blockbuster birth control pills Yaz and Yasmin to warn users that the risk of developing blood clots while taking the pills are similar to the risks with other oral contraceptives. The label change comes on the heels of hundreds of lawsuits filed both in the United States and Canada by women who say they were injured by Yaz or Yasmin but were not adequately warned of the risks associated with taking the pills. Bayer agreed to make the changes to the pills’ labels based on two large, multiyear studies of more than 120,000 women taking contraceptives in the U.S. and the U.K.
