Patient Education
Levonorgestrel Intrauterine System
Levonorgestrel intrauterine system (Liletta, Kyleena, Mirena, Skyla) is used to prevent pregnancy. The Mirena brand intrauterine system is also used to treat heavy menstrual bleeding in women who want to use an intrauterine system to prevent pregnancy. Levonorgestrel is in a class of medications called hormonal contraceptives. Levonorgestrel intrauterine system works by thinning the lining of the uterus (womb) to prevent pregnancy from developing, thickening the mucus at the cervix (entrance to the uterus) to prevent sperm from entering, and preventing sperm from moving and surviving in the uterus. Levonorgestrel may also prevent ovulation (release of an egg from the ovaries) in some women. Levonorgestrel intrauterine system is an effective method of birth control but it does not prevent the spread of AIDS and other sexually transmitted diseases.
