A hormonal intrauterine device (IUD), also known as an intrauterine system (IUS) with progestogen and sold under the brand name Mirena among others, is an intrauterine device that releases a progestogenic hormonal agent such as levonorgestrel into the uterus.[2] It is used for birth control, heavy menstrual periods, and to prevent excessive build of the lining of the uterus in those on estrogen replacement therapy.[2] It is one of the most effective forms of birth control with a one-year failure rate around 0.2%.[1] The device is placed in the uterus and lasts three to eight years.[3][4] Fertility often returns quickly following removal.[2]
Side effects include irregular periods, benign ovarian cysts, pelvic pain, and depression.[2] Rarely uterine perforation may occur.[2] Use is not recommended during pregnancy but is safe with breastfeeding.[2] The IUD with progestogen is a type of long-acting reversible birth control.[5] It works by thickening the mucus at the opening of the cervix, stopping the buildup of the lining of the uterus, and occasionally preventing ovulation.[2]
The IUD with levonorgestrel was first approved for medical use in 1990 in Finland and in the United States in 2000.[6] It is on the World Health Organization's List of Essential Medicines.[7][8]
