What are the uses of this product?
This product is a small, flexible device that is placed in the womb (uterus) to prevent pregnancy. It is used by women who want to use a reversible birth control method that works for a long time (up to 5 years). It is also used to treat heavy menstrual bleeding in women who choose to use this birth control method. The device slowly releases a hormone (levonorgestrel) that is similar to a hormone that women normally make. This device helps prevent pregnancy by making cervical fluid thicker, interfering with sperm movement, and reducing sperm survival to prevent sperm from reaching an egg (fertilization). It also changes the lining of the uterus (womb) to prevent attachment of a fertilized egg. If a fertilized egg does not attach to the uterus, it passes out of the body. This device may also stop the release of an egg from your ovary (ovulation), but this is not the way it works in most women. Using this product does not protect you or your partner against sexually transmitted diseases (such as HIV, gonorrhea, chlamydia).

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.
