Mirena Medication Information

Women who have trouble with oral forms of birth control may decide to use Mirena®, a medication that is contained within an intrauterine device (IUD). A healthcare provider inserts Mirena into a woman's uterus, where it can remain in place for up to five years. The device slowly releases a low level of the hormone levonorgestrel, which prevents pregnancy primarily by stopping ovulation, but also causes changes in the uterus and cervix.
Prior to using this medication, inform your healthcare provider if you are currently (or could be) pregnant, are breastfeeding, or have certain medical conditions, such as uterine or cervical cancer, pelvic inflammatory disease, or liver disease. In these cases, Mirena may not be the right form of birth control for you.
