One Pill. One Step.

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, which allows you to get what you need right away. Other emergency contraception requires two pills, twelve hours apart.

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.
