In the U.S., Plan B One-Step is available without age restrictions to women and men (check the family planning aisle). One-pill generics (My Way and Next Choice One Dose) will soon be available on the shelf for consumers aged 17 and older, but this change has not taken effect yet. Two-pill generics (Levonorgestrel Tablets) are still available only behind the counter without prescription if you are 17 or older; younger women need a prescription.
Plan B One-Step
The Plan B One-Step label says to take one white pill within 72 hours after unprotected sex. This dose contains 1.5 mg of levonorgestrel.
However, recent research indicates that it can be taken up to 120 hours after unprotected sex. The pill is more effective the sooner it is taken, so take Plan B One-Step as soon as possible after unprotected intercourse.
