Description
Postinor (Levonorgestrel) Tablets 0.75 mg
Ingredients
- Each tablet contains 0.75 mg of levonorgestrel as the active ingredient.
Dosage
- Take 1 tablet orally within 72 hours after unprotected intercourse.
Indications
- Postinor is indicated for emergency contraception to prevent pregnancy after unprotected sex or contraceptive failure.
Contraindications
- Avoid using Postinor if already pregnant or allergic to levonorgestrel.
Directions
- Swallow the tablet whole with water for best results. The effectiveness increases the sooner it is taken after unprotected intercourse.
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.
Scientific Evidence
- Studies have shown that levonorgestrel in Postinor primarily works by preventing ovulation and altering cervical mucus to inhibit sperm penetration. Clinical trials have demonstrated its high effectiveness in reducing the risk of pregnancy when used as directed.
Additional Information
- Postinor is not meant for regular contraception and should be used only in emergencies. Consult a healthcare provider for advice on regular birth control methods. It does not protect against sexually transmitted infections.
Clinical Trials
- Research published in the American Journal of Obstetrics and Gynecology indicated that levonorgestrel emergency contraception, like Postinor, reduced the risk of pregnancy by 85% when taken within 72 hours of unprotected intercourse.
