1. What is emergency contraception (EC)?

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


2. What is Plan B®?

Plan B® is the only FDA-approved 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 after contraceptive failure, unprotected intercourse, or sexual assault, Plan B® reduces the chance of pregnancy by up to 89%.


3. How does Plan B® work?

Emergency contraception is similar to a birth control pill, and is believed to act by:

  • Preventing ovulation
  • Possibly preventing fertilization by altering tubal 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. When was Plan B® approved?

Plan B® was first approved by the FDA for prescription use in July 1999. In August 2006, Plan B® was approved for OTC use by consumers 18 years and older. Women 17 and younger still require a prescription.


5. Is Plan B® RU-486 (the abortion pill)?

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


6. What if a patient is already pregnant when she takes Plan B®?

There is no medical evidence that Plan B® 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.
