LILETTA (levonorgestrel)

Women's Health Approved 2015-02-26

LILETTA is a progestin-containing intrauterine system used for long-term pregnancy prevention for up to eight years. It also treats heavy menstrual bleeding for up to five years in patients who choose an intrauterine device as their method of contraception. This system provides a continuous release of hormones directly within the uterus to help patients manage their reproductive health and menstrual flow over several years.

How LILETTA Works

While the exact local mechanism has not been conclusively demonstrated, LILETTA is believed to prevent fertilization through several local actions: thickening the cervical mucus to inhibit sperm passage, inhibiting sperm mobility and function (capacitation), and altering the endometrium.
