In the U.S., progestin-only EC is available on the shelf without age restrictions to women and men. Look for Plan B One-Step, Take Action, Next Choice One-Dose, My Way or other generics in the family planning aisle.
The Plan B package instructions state that you should take 1 white pill within 72 hours after unprotected sex and 1 more white pill 12 hours later. Each dose contains 0.75 mg of levonorgestrel. The two pills are identical; it does not matter which pill you take first.
However, recent research indicates that both doses can be taken at the same time up to 120 hours after unprotected sex. The pills are more effective the sooner they are taken, so take 2 Plan B pills at the same time as soon as possible after unprotected intercourse.
Plan B has been replaced by the one-pill product Plan B One-Step.
