Medical abortion is highly effective.
The combination of Mifepristone with misoprostol is highly effective, safe and acceptable. A complete abortion (meaning that a woman will not need additional care) will occur up to 98% of the time if a woman is less than12 weeks pregnant.
Approximately 2–5% of women treated with the combination of mifepristone and misoprostol may require additional medical care to resolve an incomplete abortion, terminate a continuing pregnancy, or control bleeding. 1
Misoprostol alone for early pregnancy termination results in a complete abortion occurs in 84%12 of women.
The earlier the medical abortion is done the more effective and safe it will be. 2
