Key clinical point: Expulsion rates were similar for women using a 52 mg levonorgestrel intrauterine system for heavy menstrual bleeding and those who used it for contraception; a history of cesarean delivery increased the risk of expulsion in both groups.
Major finding: Expulsion of the device occurred in 548 of the women with heavy menstrual bleeding (5.6%) and 315 of the women using the device for contraception (5.6%). The odds ratio for expulsion for women with a history of cesarean delivery in either group was 1.93.
Study details: The data come from an audit of 548 women who used a 52 mg levonorgestrel intrauterine system to manage heavy menstrual bleeding and 5,655 who used it for contraception.
Disclosures: The study received no outside funding. The researchers had no financial conflicts to disclose.
