levonorgestrel-releasing 5 year system - intrauterine, Mirena
GENERIC NAME: LEVONORGESTREL-RELEASING 5 YEAR SYSTEM - INTRAUTERINE (LEE-voe-nor-JES-trel)
BRAND NAME(S): Mirena
USES: This product is a small, flexible device that is placed in the womb (uterus) to prevent pregnancy. It is used by women who have had at least one child and 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 thins the lining of the uterus (womb). 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).
