HOW DOES
KYLEENA® WORK?

Kyleena® may work to prevent pregnancy in several ways including:

  1. Reducing the monthly thickening of the lining of the uterus
  2. Thickening the mucus in the cervix
    (this makes it harder for sperm to pass through the cervix)
  3. Impairing sperm movement and function

Together, these actions prevent the sperm and egg from coming into contact and work together to prevent pregnancy.

Important aspects of Kyleena®:

  • Releases a low amount of a hormone called levonorgestrel directly into the uterus every day (Kyleena® contains 19.5 mg of levonorgestrel)
  • Does not contain any estrogen

Kyleena® is a long acting reversible contraceptive (LARC).
LARCs are highly effective in preventing pregnancy, can be used for a long period of time, and are easy to use.
