1. What is emergency contraception (EC)?

There are many misperceptions about EC and how it works. EC is a backup option to help prevent an unplanned pregnancy after contraceptive failure, or unprotected intercourse.


2. What is Plan B® One-Step?

Plan B® One-Step is the only FDA-approved single-tablet, single-dose emergency contraception currently available. Levonorgestrel is well trusted and has been commonly used in many birth control pills for over 35 years. When taken as directed— within 72 hours (3 days) after contraceptive failure or unprotected intercourse—approximately seven out of eight women who would have gotten pregnant will not become pregnant after taking Plan B® One-Step.


3. How does Plan B® One-Step work?

Emergency contraception is similar to a birth control pill, and works primarily by:
  • Preventing ovulation
  • Possibly preventing fertilization by altering tubular transport of sperm and/or egg
  • Altering the endometrium, which may inhibit implantation
EC is not effective once the process of implantation has begun. It will not affect an existing pregnancy or harm a developing fetus.


4. Is Plan B® One-Step RU-486 (the abortion pill)?

No. Plan B® One-Step is not RU-486 (the abortion pill). Plan B® One-Step is an emergency contraceptive (EC) that helps prevent an unplanned pregnancy after contraceptive failure or unprotected intercourse. Plan B® One-Step will not affect an existing pregnancy.


5. What if a patient is already pregnant when she takes Plan B® One-Step?

There is no medical evidence that Plan B® One-Step would harm a developing fetus. Many studies have found no effects on fetal development associated with long-term use of progestin-only contraceptive pills (POPs). The few studies of infant growth and development that have been conducted with POPs have not demonstrated significant adverse effects.
