Postinor is a highly effective emergency contraceptive pill containing 2 tablets to be taken after unprotected intercourse to prevent pregnancy. Each tablet contains Levonorgestrel, a synthetic hormone that works by preventing ovulation and fertilization. Levonorgestrel also alters the cervical mucus and uterine lining, making it difficult for sperm to reach the egg or for a fertilized egg to implant in the uterus. This emergency contraceptive should be used within 72 hours of unprotected sex for maximum effectiveness. Postinor provides a reliable option for women in need of emergency contraception, offering peace of mind and control over their reproductive health.
