What is the success rate of medical abortion?

The success rate of medical abortion is about 90%.

Medical abortion is mainly performed by using specific drugs, such as mifepristone and misoprostol, to stop the development of embryos and expel them from the body. If the patient responds well to the drugs, the success rate is relatively high. In addition, medical abortion performed at a shorter time of pregnancy usually has a higher success rate. Generally, medical abortion is performed within 49 days of pregnancy. As pregnancy progresses, the embryo may grow larger and become more closely associated with the uterus, increasing the risk of incomplete abortion.

It should be noted that although medical abortion is relatively convenient, there are certain risks and limitations. Before medical abortion, patients should undergo detailed examinations, including ultrasound to confirm intrauterine pregnancy and to assess physical condition.
