Compared with induced abortion, medical abortion has the least harm to patients and the fastest recovery. Because there is no intrauterine operation in drug abortion, the patient only causes uterine contraction after taking the medicine, and promotes the discharge of gestational sac and decidua, thus achieving the purpose of abortion.

However, induced abortion requires the use of instruments to enter the uterine cavity to suck the uterus, and at the same time, the function of the patient's endometrium and ovary will be affected to some extent, so the injury is relatively large and the postoperative recovery is relatively slow. But there is the possibility of drug abortion failure. If the patient fails to do medical abortion, it must be remedied by clearing the palace. The operation process of clearing the palace is similar to that of induced abortion, which also has an impact on patients.
