Levonorgestrel-releasing intrauterine system is a device that contains the female hormone, levonorgestrel. It is placed in the uterus (womb) where it slowly releases the hormone to prevent pregnancy for up to 3 years for Liletta™ or Skyla™ or up to 5 years for Kyleena™ or Mirena®. It works by stopping a woman's egg from fully developing each month. The egg can no longer accept a sperm and fertilization (pregnancy) is prevented.

Levonorgestrel-releasing intrauterine system is also used to treat heavy menstrual bleeding in women. It works best in women who have had at least one child.
