There is a lot of misconceptions about mifepristone, also known as RU-486 or the abortion pill. Many on the anti-choice side say that mifepristone is the same as emergency contraception, which is also known as Plan B, but they are not the same thing.
Mifepristone is a steroid that is used to induce abortion. It was first approved in France in 1980, however the FDA did not approve mifepristone until September 28, 2000. Mifepristone can be used to induce abortion up to 49 days after the beginning of the last menstrual period. The drug must be administered by a physician, and it is not available in a pharmacy.
Emergency contraception, or Plan B, is different. It is taken by women who are not pregnant who want to prevent pregnancy. It must be taken within 72 hours of unprotected sex. It has no effect on an already established pregnancy. Emergency contraception is available over the counter for women who are over 17 years old.
