Patient Education
Levonorgestrel
Levonorgestrel is used to prevent pregnancy after unprotected sexual intercourse (sex without any method of birth control or with a birth control method that failed or was not used properly [e.g., a condom that slipped or broke or birth control pills that were not taken as scheduled]). Levonorgestrel should not be used to prevent pregnancy on a regular basis. This medication is to be used as an emergency contraceptive or backup in case regular birth control fails or is used incorrectly. Levonorgestrel is in a class of medications called progestins. It works by preventing the release of an egg from the ovary or preventing fertilization of the egg by sperm (male reproductive cells). It also may work by changing the lining of the uterus (womb) to prevent development of a pregnancy. Levonorgestrel may prevent pregnancy, but it will not prevent the spread of human immunodeficiency virus (HIV, the virus that causes acquired immunodeficiency syndrome [AIDS]) and other sexually transmitted diseases.

Levonorgestrel Intrauterine System
Levonorgestrel intrauterine system (Liletta, 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.
