Levonorgestrel is available in different forms, including oral tablets and intrauterine devices (IUDs). The most common uses are:
Emergency Contraception: Levonorgestrel pills, often referred to as the "morning-after pill," are used to prevent pregnancy after unprotected sex or contraceptive failure. It is most effective when taken within 72 hours. Long-term Contraception: Levonorgestrel-releasing IUDs, such as Mirena and Skyla, provide long-term contraception by releasing small amounts of the hormone over several years.
