The administration of mifepristone, a powerful antiprogestin, coupled with a prostaglandin
is a highly effective medical method of terminating pregnancy
. In 1993, a large French trial confirmed the safety and efficacy of a regimen consisting of mifepristone and oral misoprostol.
This regimen, with a success rate of 96%, has been used extensively now.
The side effects are nausea, vomiting, cramping, pain, diarrhea
etc and is far more common among the medical abortion
clients than among the women who chose surgical abortion.
Most notable side effect of this abortion pill was found to be excessive and prolonged bleeding in many patients.
Overall this method of abortion with use of medicines is quite safe and efficacious.
