Mifepristone
The French abortion pill, also known as RU-486. RU-486 has been used in combination with another drug called misoprostol, to terminate pregnancy at an early stage.
It is used with women who are no more than 7 weeks pregnant.
The drug has 95% effectiveness.
About 5% of women using RU-486 in early pregnancies need additional medical intervention because of incomplete abortions.
(doctors often intervene at higher rates in cases of natural miscarriages).
The side effects with RU-486 are similar to those of a natural miscarriage.
