What is the most common abortion medication used in the United States?
The most common abortion medication used in the United States is RU486 which is also known as Mifeprex, Mifepristone, Abortion Pill, or French pill. RU486 was approved by the FDA in 2001 specifically for termination of pregnancy. It works by altering the blood flow to the lining of the uterus as well as causing an increase in the intrauterine pressure that leads to inadequate blood flow to the pregnancy, and causes uterine contractions which lead to spontaneous vaginal bleeding and miscarriage. There is approximately a 40 percent chance of the loss of pregnancy with the use of RU486 alone if used in pregnancies less than 6 weeks gestation. The RU486 pill has been found to be very safe and highly effective with a 96 percent success rate of termination of pregnancy up to 9 weeks gestation and near 100 percent for pregnancies less than 6 weeks gestation.
