Mifeprex (RU-486 / Medical Abortion Pill)

Procedure

The FDA approved regimen ² for Mifiprex (RU-486) is a two-visit process using two different drugs:

1. Mifepristone is given orally during the first office visit (200 mg). Mifepristone blocks progesterone from sustaining the pregnancy, thereby ending the life of the baby.
2. Misoprostol tablets are given orally (800 mcg) 48 hours later. The misoprostol will cause contractions to expel the baby’s remains. This does not take place at the medical office and may occur within a few hours or up to two weeks after taking misoprostol.
3. A physical exam is given by the healthcare provider about 7-14 days later to ensure the abortion is complete and that there are no immediate complications.
