Plan B One-Step® is a backup plan that helps prevent pregnancy after birth control failure. The sooner you take emergency contraception, the better it works. Plan B One-Step® is just one pill, so you get what you need right away.
With Plan B One-Step®, you have up to 72 hours (3 days) to prevent a pregnancy. Plan B One-Step® is not the abortion pill and it isn’t a substitute for routine birth control.
