Roughly 2 million American women, or 10% of birth control users, use the Mirena intrauterine device (IUD) for birth control. That growing number brings concerns, according to some health experts who worry not enough information about Mirena IUD side effects is available to make decisions.
Heather Boonstra, director of public policy at the Guttmacher Institute, notes that neither patients nor doctors know enough about IUDs as a form of birth control, though the devices have been linked to severe complications. Some Mirena side effects include perforating the uterus and migrating through the body, as well as heavy menstrual bleeding and the lack of protection from sexually transmitted diseases.
As device users increase, so too do Mirena IUD complaints filed to the U.S. Food and Drug Administration. To date, more than 70,000 Mirena complaints have been reported to the FDA from patients who have experienced a range of Mirena side effects. Device manufacturer Bayer is expected to face thousands of Mirena lawsuits alleging the IUD caused serious complications.
