Mifepristone

Mifepristone is used alone or in combination with misoprostol (Cytotec) to end an early pregnancy. Early pregnancy means it has been 49 days or less since your last menstrual period began. Mifepristone is in a class of medications called antiprogestational steroids. It works by blocking the activity of progesterone, a substance your body makes to help continue pregnancy.

Mifepristone comes as a tablet to take by mouth. It should be taken only in a clinic, medical office, or hospital under the supervision of a qualified doctor. You will take three tablets of mifepristone at one time on the first day. Two days later you must go back to your doctor. If your doctor is not certain that your pregnancy has ended, you will take two tablets of another medication called misoprostol. You may have vaginal bleeding for 9 to 30 days or longer. Fourteen days after taking mifepristone, you must go back to your doctor for an exam or ultrasound to make sure that the pregnancy has ended. Take mifepristone exactly as directed.
