Taking Plan B

Sometimes you need a backup plan.

And when you do, there’s Plan B—the #1 OB/GYN recommended emergency contraception brand.

When to use Plan B

Plan B is emergency contraception you can take when:

  • You didn’t use any form of birth control and had unprotected sex
  • There was an issue with your regular birth control method (e.g., the condom broke or slipped)
  • You missed a dose (or more) of your regular birth control pill and had sex

How to take Plan B

Plan B emergency contraception helps prevent pregnancy by temporarily delaying ovulation. Here’s what you need to know about taking it:

  • It’s a single tablet you take by mouth.
  • Must be taken within 72 hours after unprotected sex. The sooner you take it, the better it works.


Plan B won’t protect you against HIV/AIDS or any other sexually transmitted diseases (STDs).
