  • What is Plan B One-Step®?

    Plan B One-Step® is emergency contraception that helps prevent pregnancy after birth control failure or unprotected sex. It is a backup method of preventing pregnancy and should not be used as regular birth control.

  • What Plan B One-Step® is not.

    Plan B One-Step® will not work if you are already pregnant and will not affect an existing pregnancy. Plan B One-Step® will not protect you from HIV infection (the virus that causes AIDS) and other sexually transmitted diseases (STDs).

  • When should I use Plan B One-Step®?

    The sooner you take emergency contraception, the better it works. You should use Plan B One-Step® within 72 hours (3 days) after you have had unprotected sex.

    Plan B One-Step® is a backup or emergency method of birth control you can use when:

    • your regular birth control was used incorrectly or failed
    • you did not use any birth control method
  • When not to use Plan B One-Step®.

    Plan B One-Step® should not be used:

    • as a regular birth control method, because it’s not as effective as regular birth control.

  • When should I talk to a doctor or pharmacist?

These medications may reduce the effectiveness of Plan B One-Step® and increase your chance of becoming pregnant. Your doctor may prescribe another form of emergency contraception that may not be affected by these medications.

  • How does Plan B One-Step® work?

    Plan B One-Step® is one tablet with levonorgestrel, a hormone that has been used in many 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 prevent pregnancy. It works mainly by stopping the release of an egg from the ovary. It is possible that Plan B One-Step® may also work by preventing fertilization of an egg (the uniting of sperm with the egg) or by preventing attachment (implantation) to the uterus (womb).
