Mifepristone + Misoprostol is a combination of two medicines: Mifepristone and Misoprostol, which causes abortion. Mifepristone blocks the effects of progesterone, a natural female hormone that is needed for the pregnancy to sustain. Without this hormone, the lining of the uterus (womb) breaks down as it does during a menstrual period and stops the growth of the pregnancy. Misoprostol increases contractions of the uterus to cause abortion.
Mifepristone (also known as RU 486) is used to cause an abortion during the early part of a pregnancy. It is used up to week 10 of pregnancy (up to 70 days after the first day of your last menstrual period). Mifepristone blocks a natural substance (progesterone) that is needed for your pregnancy to continue
Misoprostol helps to decrease your risk of serious ulcer complications such as bleeding. This medication protects your stomach lining by lowering the amount of acid that comes in contact with it. This medication is also used in combination with another drug (mifepristone) to end a pregnancy (abortion).
