Mifeprex (RU-486 / Medical Abortion Pill)

  • Gestational Age: within 10 weeks of last menstrual period
  • Cost: $350-$650


The FDA approved regimen1 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.

The abortion pill is not advised for women who have anemia, bleeding disorders, liver or kidney disease, seizure disorder, acute inflammatory bowel disease, use an intrauterine device (IUD), or are unable to return for the follow-up visit.

What is abortion pill reversal?

Progesterone is the natural hormone created by a woman’s body necessary to nurture and sustain a pregnancy. Mifepristone blocks this hormone. By delivering progesterone into your body, it’s possible to counteract the effects of the Mifepristone.

Your appointment will begin with  an ultrasound exam to confirm that your baby is alive. If your baby is viable, your medical abortion reversal will involve natural progesterone treatments delivered orally, vaginally or by injection, usually through the end of the first trimester.
