Scientific Evidence

Postinor containing levonorgestrel has been extensively studied for its efficacy in preventing pregnancy. Research has shown that levonorgestrel works primarily by preventing ovulation and altering the cervical mucus to inhibit sperm penetration. Clinical trials have demonstrated that Postinor is highly effective in reducing the risk of pregnancy when taken as directed.

Additional Information

It is important to note that Postinor is not intended for regular contraception and should only be used in emergency situations. Consult a healthcare provider for advice on regular birth control methods. Postinor does not protect against sexually transmitted infections.

Pharmacological Effects: Levonorgestrel, the active ingredient in Postinor, acts as a progestin hormone that prevents pregnancy by inhibiting ovulation, fertilization, or implantation of the egg. It thickens the cervical mucus, making it harder for sperm to reach the egg, and thins the lining of the uterus, preventing implantation.

Clinical Trials: Clinical studies have shown that levonorgestrel emergency contraception is a safe and effective method for preventing pregnancy when used correctly. A study published in the American Journal of Obstetrics and Gynecology found that levonorgestrel reduced the risk of pregnancy by 85% when taken within 72 hours of unprotected intercourse.
