Mirena intrauterine device (IUD) expulsion could occur in up to 10% of women who use it, according to doctors. Other women could experience device migration, which occurs when the birth control device perforates the uterus and travels to other parts of the body, often causing severe complications.
The Mirena IUD is used by about 2 million American women, more than 70,000 of which have filed complaints to the U.S. Food and Drug Administration documenting complications. Complaints include device expulsion or migration that can sometimes go unnoticed until creating further problems.
Bayer Pharmaceuticals is facing thousands of Mirena lawsuits alleging that the company failed to warn patients and doctors about the risks of Mirena, including potentially downplaying the risks while overemphasizing efficacy. Mirena side effects include pain, tissue damage, internal bleeding and ectopic pregnancy.
