Norpill 1.5 mg Tablet is an emergency contraceptive designed to prevent pregnancy after unprotected sexual intercourse or contraceptive failure. Each tablet contains 1.5 mg of Levonorgestrel, a synthetic progestogen that primarily works by inhibiting or delaying ovulation. It may also prevent fertilization or implantation by altering the endometrial lining. Norpill is intended for occasional use and should not replace regular contraceptive methods. It is most effective when taken as soon as possible, preferably within 12 hours, and no later than 72 hours (3 days) after unprotected intercourse. The tablet can be taken at any time during the menstrual cycle, provided that pregnancy is not already established
