RU-486 (Mifepristone (Mifeprex) and Misoprostol)
- Mifepristone is given orally during your first office visit. Mifepristone blocks progesterone from the uterine lining, causing the fetus to die. This alone may cause contractions to expel the fetus.
- Misoprostol tablets are given orally or inserted vaginally during the second office visit which occurs 36 to 48 hours later.
- You will return home where the misoprostol will start contractions and expel the fetus. This may occur within a few hours or in some cases up to two weeks after taking the misoprostol.
- A physical exam is given two weeks later to ensure the abortion was complete and that there are no immediate complications.
Risks and Side Effects:
- The procedure is unsuccessful approximately 8-10% of the time, thus requiring an additional surgical abortion procedure to complete the termination.
- Heavy bleeding
- Not advised for women who have anemia, bleeding disorders, liver or kidney disease, seizure disorder, acute inflammatory bowel disease, or use an intrauterine device (IUD)
