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.
