Mifeprex blocks the actions of a hormone needed to maintain a pregnancy.
Mifepristone is used to end an early pregnancy (no further along than 7 weeks, or 49 days after the first day of your last menstrual period). Mifepristone can cause birth defects in an unborn baby if the treatment procedure does not fully terminate the pregnancy. If you are still pregnant after 2 weeks, you may need surgery to end the pregnancy completely.
Day 1: Three 200 mg tablets (600 mg total) orally administered as a single, one time dose.
Day 3: The patient returns to the health care provider 2 days after mifepristone ingestion. Unless termination of pregnancy has been confirmed via clinical examination or ultrasonographic scan upon follow-up visit, the patient is given two 200 mcg tablets (400 mcg total) of MISOPROSTOL orally, administered as a single dose one time. The patient then returns 14 days after administration of mifepristone to confirm complete termination of early pregnancy.
