Skyla® is indicated to prevent pregnancy for up to 3 years. The system should be replaced after 3 years if continued use is desired. Skyla contains 13.5 mg of levonorgestrel (LNG) released in vivo at a rate of approximately 14 mcg/day after 24 days. This rate decreases progressively to 5 mcg/day after 3 years.

Is Skyla less effective over time?

Skyla is an IUD that releases a low dose of hormones and is over 99% effective at preventing pregnancy for up to 3 years.

Can you get pregnant after Skyla expires?

IUDs have expiration dates. If you keep one in longer than the suggested amount of time, you have a slightly higher chance of pregnancy. But it's still less than 1%. You probably won't have any side effects if you keep an IUD in after it expires, but we need more research to safely recommend this option.
