Emergency contraception called Levonorgestrel Tablet is used to stop pregnancy during unprotected intercourse or when other birth control methods have failed. It operates by halting the entire development of a woman’s egg. Additionally, it may stop the woman’s egg from adhering to the uterus wall (womb).

There is no 100% effective contraceptive method. Less effective forms of birth control include undergoing sterilization surgery or refraining from having intercourse. Regular use of this medication as a form of birth control is not advised. Your doctor should be informed of your contraceptive choices.

Any woman with the capacity to bear children can purchase Plan B One-Step® as an over-the-counter medication.
