Since Mirena was first approved by the U.S. Food and Drug Administration in 2000, millions of women have used the intrauterine device (IUD) to prevent unwanted pregnancies and treat heavy menstruation.
Most women use Mirena without issue. However, a growing number of women have reported serious side effects, such as infection, perforation, false brain tumors, device expulsion, and more. The severe and sometimes unexpected complications have led to thousands of women filing lawsuits against the manufacturer of Mirena.
Lawsuits have been working their way through the legal system as plaintiffs accuse drugmaker Bayer of overstating the benefits of Mirena, concealing risks, failing to warn consumers, and more.
