CHAPTER 10 - Levonorgestrel Intrauterine Device: Only the Essentials
- 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).
