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 Skyla® or up to 5 years for Kyleena™, Liletta®, 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 who choose this device as their method for birth control.

Levonorgestrel is to be given only by or under the supervision of your doctor.
