Mirena is a T-shaped plastic IUD that releases continuous doses of a hormone, levongorgesterel, which is intended to prevent pregnancy for up to five years after implantation. Although the majority of women who use Mirena are satisfied by the product, dangerous side effects and injuries have been reported including pelvic pain, pelvic inflammatory disease, perforation of the uterus or cervix, ectopic pregnancy, and intrauterine pregnancy.
