Skyla contains levonorgestrel, a female hormone that can cause changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.

Skyla intrauterine device (IUD) is a small, flexible plastic T-shaped device. This device is placed in the uterus where it slowly releases the hormone to prevent pregnancy for 3 years. (Other types of levonorgestrel intrauterine systems release different amounts of hormone and are used for different lengths of time.)

Skyla can be used whether you have had children or not. It should not be used during pregnancy.

Levonorgestrel is a progestin hormone and does not contain estrogen. The Skyla IUD releases levonorgestrel in the uterus, but only small amounts of the hormone reach the bloodstream. Skyla should not be used as emergency birth control.
