The Mirena intrauterine device (IUD) contains levonorgestrel, a female hormone that can cause changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus. Mirena is a plastic device that is placed in the uterus where it slowly releases the hormone to prevent pregnancy up to 5 years.

Mirena is used to prevent pregnancy for up to 5 years. It can be used whether or not you have had a child. Mirena is also used to treat heavy menstrual bleeding in women who choose to use an intrauterine form of birth control.

Levonorgestrel is a progestin hormone and does not contain estrogen. The intrauterine device (IUD) releases levonorgestrel in the uterus, but only small amounts of the hormone reach the bloodstream. Mirena should not be used as emergency birth control.
