Only the Essentials

Key Points for Providers and Clients
Long-term pregnancy protection. Very effective for 5 years, immediately reversible. Inserted into the uterus by a specifically trained provider. Little required of the client once the LNG-IUD is in place. Bleeding changes are common but not harmful. Typically, lighter and fewer days of bleeding, or infrequent or irregular bleeding.

What Is the Levonorgestrel Intrauterine Device?

The levonorgestrel intrauterine device (LNG-IUD) is a T-shaped plastic device that steadily releases small amounts of levonorgestrel each day. (Levonorgestrel is a progestin widely used in implants and oral contraceptive pills.)
A specifically trained health care provider inserts it into a woman's uterus through her vagina and cervix.
Also called the levonorgestrel-releasing intrauterine system, LNG-IUS, or hormonal IUD.
Marketed under the brand name Mirena.
Works primarily by suppressing the growth of the lining of uterus (endometrium).
