Mirena IUD Review Criteria


Mirena (Levonorgestrel-releasing intrauterine system) is a small flexible, t-shaped plastic device that is inserted into the uterus by a healthcare provider and works as a contraceptive by releasing a low dose of levonorgestrel (a synthetic progestin hormone) directly into the uterus. The hormone in Mirena is designed to prevent pregnancy by thinning the lining of the uterus, thereby preventing sperm from reaching and fertilizing and egg, and by thickening cervical mucus to prevent sperm from entering the uterus.

Mirena was approved by the Food and Drug Administration (FDA) in 2000 and is recommended to women who have had at least one child. The device can be left in place for up to five years. Mirena was also FDA-approved in 2009 to treat heavy menstrual bleeding in women who prefer intrauterine contraception as their method of birth control, the first time that the FDA has approved an intrauterine device for this purpose.
