OBJECTIVE To compare the expulsion rates of the levonorgestrel (LNG) 52 mg intrauterine system (IUS) among women with heavy menstrual bleeding versus women using solely for contraception. STUDY DESIGN We conducted an audit study of 548 (8.8%) women with heavy menstrual bleeding and 5,655 (91.2%) users for contraception (comparison group) for four years in Campinas, Brazil. We retrieved sociodemographic data, expulsion rates, and variables associated to device placement. Among women with heavy menstrual bleeding, we placed the devices after the cessation of bleeding or after the reduction of menstrual flow. RESULTS Thirty-one of 548 (5.6%) women with heavy menstrual bleeding and 315 of 5,655 (5.6%) from the comparison group expelled the device. This constituted 7.8 expulsions/100 women-years in women with heavy menstrual bleeding and 10.3 expulsions/100 women-years from the comparison group (p = 0.94). Expulsion risk was associated with previous cesarean delivery in both groups (OR 1.93, 95% CI 1.36;2.74). CONCLUSIONS Expulsion rates of the LNG IUS among women with heavy menstrual bleeding whose IUS was placed after the cessation or reduction of bleeding were similar to expulsion rates among users for contraception. Previous cesarean delivery was a risk factor for expulsion.
