Levonorgestrel, such as Plan B or Next Choice, is specially packaged for emergency contraception. You can buy this medicine in most drugstores.
Emergency contraception is used after unprotected sex to prevent a pregnancy from starting. It is most effective when it is used as soon as possible after intercourse. It is not necessary to take a pregnancy test before using emergency contraception.
Birth control experts recommend having emergency contraception pills, or a prescription for them, on hand in case you ever need them. Emergency contraception is most effective when used as soon as possible after unprotected sex. Your risk of becoming pregnant increases as time passes.
For the emergency contraception option that contains 2 pills, you can take both pills at the same time. Or you can take 1 pill right away and the second pill 12 hours later.
There is also a one-pill emergency contraception option that lets you take the dose you need in just 1 pill.
You can take emergency contraception up to 5 days after unprotected sex. But it works best if you take it right away.
