Emerginor Levonorgestrel tablets (p2 pills, p2 tablets, Plan B) are used by women to prevent pregnancy after birth control failure (such as a broken condom) or unprotected sex. Emerginor Levonorgestrel is taken orally and contains the hormone levonorgestrel, which works by preventing the release of an egg from the ovary or by stopping sperm from fertilizing the egg. To maximize effectiveness, it is crucial to take the medication as soon as possible, ideally within 72 hours after unprotected sex or contraceptive failure. Levonorgestrel is not intended for routine use and should not replace regular birth control methods; it is specifically designed for emergency situations.
