A number of lawsuits have been filed by women who allege Bayer downplayed the seriousness of possible Mirena side effects. Plaintiffs in these lawsuits claim they experienced serious, and in some cases life-threatening Mirena complications after the device migrated from its original location, sometimes months or years after placement. Spontaneous device migration can lead to a myriad of problems, according to these lawsuits, including uterine perforations, uterine rupture, infection, scarring and adhesions, organ damage (if the IUD migrates outside of the uterus), and ectopic pregnancy.
