Mechanism of Action

Medicine is not effective if a woman is already pregnant. Generic Plan B is believed to act as an emergency contraceptive principally by preventing ovulation or fertilization by altering tubal transport of sperm and/or ova. It may inhibit implantation by altering the endometrium. It is not effective once the process of implantation has begun.


Take Generic Plan B One-Step orally as soon as possible within 72 hours after unprotected intercourse or a known or suspected contraceptive failure. Efficacy is better if the tablet is taken as soon as possible after unprotected intercourse. The drug can be used at any time during the menstrual cycle.If vomiting occurs within two hours of taking the tablet, consideration should be given to repeating the dose.
