What Plan B One-Step is:

  • The # 1 OB/GYN recommended brand* of emergency contraception1
  • Easy to find in the family planning aisle of many retail stores when your patient needs it—available without a prescription or ID and with no age restriction
  • The brand chosen by millions of women3
  • Emergency contraception that contains levonorgestrel, the same hormone in many birth control pills—just at a higher dose. It should not be used as regular birth control because it is not as effective

What Plan B One-Step is NOT:

  • It is NOT an abortion pill
  • It will not work if a woman is already pregnant
  • It will not affect an existing pregnancy
  • It does not protect against HIV/AIDS or other sexually transmitted infections (STIs)
  • It should not be used if a patient is allergic to levonorgestrel or any other ingredients in Plan B One-Step

How does Plan B One-Step work?

Plan B One-Step is a progestin-only emergency contraception. Each tablet contains levonorgestrel, a hormone that has been used in birth control pills for several decades. Plan B One-Step contains a higher dose of levonorgestrel than birth control pills, but works in a similar way to help prevent pregnancy.

Plan B One-Step works primarily by:

  • Preventing ovulation

It may also work by:

  • Possibly preventing fertilization by altering tubal transport of sperm and/or egg
  • Altering the endometrium which may inhibit implantation

Plan B One-Step should be taken as soon as possible within 72 hours (3 days) after unprotected intercourse. The sooner it’s taken, the better it works.

Efficacy

If Plan B One-Step is taken as directed, it can significantly decrease the chance that a woman will get pregnant. About 7 out of every 8 women who would have gotten pregnant will not become pregnant after taking Plan B One-Step.

It is important to remind patients that Plan B One-Step is a backup method of preventing pregnancy and should not be used as regular birth control because it is not as effective.
