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.
• if you are already pregnant, because it will not work.
• if you are allergic to levonorgestrel or any other ingredients in Plan B One-Step®.

When should I talk to a doctor or pharmacist?

Ask a doctor or pharmacist before use if you are taking efavirenz (HIV medication) or rifampin (tuberculosis treatment) or medication for seizures (epilepsy). 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).

How can I get the best results from Plan B One-Step®?

You have 72 hours (3 days) to try to prevent pregnancy after birth control failure or unprotected sex. The sooner you take Plan B One-Step®, the better it works.

How effective is Plan B One-Step®?

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

How will I know Plan B One-Step® worked?

You will know Plan B One-Step® has been effective when you get your next period, which should come at the expected time, or within a week of the expected time. If your period is delayed beyond 1 week, it is possible you may be pregnant. You should get a pregnancy test and follow up with your healthcare professional.

Will I experience any side effects?

• some women may have changes in their period, such as a period that is heavier or lighter or a period that is early or late. If your period is more than a week late, you may be pregnant.
• if you have severe abdominal pain, you may have an ectopic pregnancy, and should get immediate medical attention.
• when used as directed, Plan B One-Step® is safe and effective. Side effects may include changes in your period, nausea, lower stomach (abdominal) pain, tiredness, headache, dizziness, and breast tenderness.
• if you vomit within 2 hours of taking the medication, call a healthcare professional to find out if you should repeat the dose.
