1. What is emergency contraception (EC)?
There are many misperceptions about EC and how it works. Simply put, EC is a second chance to help prevent an unplanned pregnancy after contraceptive failure, unprotected sex, or sexual assault. Currently, EC is available in 101 countries, 33 of which do not require a prescription.5 Emergency contraception is similar to a birth control pill, and is believed to act by:
- Preventing ovulation
- Preventing fertilization by altering tubal transport of sperm and/or egg
- Possibly inhibiting implantation by altering the endometrium
It is important to note that EC is not effective once the process of implantation has begun. It will not affect an existing pregnancy or harm a developing fetus.

2. What is Plan B®?
Plan B® is the only FDA-approved emergency contraceptive composed of progestin-only (levonorgestrel) tablets. Levonorgestrel is a well-trusted and commonly used progestin that is associated with a low incidence of side effects. When taken as directed within 72 hours after contraceptive failure, unprotected sex, or sexual assault, Plan B® reduces the risk of pregnancy by up to 89%. However, studies show that Plan B® is effective when taken within 72 hours, and is more effective when taken within 24 hours.1

4. 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 sex, or sexual assault. RU-486 (mifepristone) has anti-progesterone activity and may be used to induce a medical abortion up to 49 days gestation in pregnant women. Plan B® will not affect an existing pregnancy. As described in the Plan B®Prescribing Information, the progestin levonorgestrel is believed to act as an EC principally by preventing ovulation and/or fertilization by altering tubal transport of sperm and/or ova. In addition, it may inhibit implantation by altering the endometrium. It is not effective once the process of implantation has begun, and it will not harm a developing fetus.

5. Can my patients take both tablets at the same time?
Although there have been studies8,9 on this, this dosing regimen is not FDA approved. Plan B® is simple to take and consists of only 2 tablets. The first tablet should be taken as soon as possible within 72 hours after contraceptive failure, unprotected sex, or sexual assault. The second tablet should be taken 12 hours after the first dose. And remember, Plan B® is more effective the sooner it is taken.1

6. Doesn’t Plan B® work even after 72 hours?
Although there have been studies9,10 on this, it is not FDA approved. Plan B® is proven to be more effective the sooner it is taken,1 and Plan B® reduces the rate of pregnancy by up to 89% when taken as directed within 72 hours after contraceptive failure, unprotected sex, or sexual assault.

7. 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.
