The probability of a complete clean abortion with medication is around 60-90%, which is related to the sensitivity of each individual to the medication. Medication abortion is the combined application of mifepristone and misoprostol, which causes degeneration and necrosis of the uterine metaplasia, softening of the cervix, and contraction of the uterus to induce the expulsion of the embryo. Medical abortion is indicated for healthy women within 49 days of menopause, less than 40 years of age, and who have been diagnosed with intrauterine pregnancy by ultrasound. The success rate of abortion is affected by various factors, such as the history of pregnancy and delivery, the number of abortions, the presence of combined endometritis, the presence of uterine scars and the sensitivity to drugs. The success rate is lower if the abortion has been performed several times or if there have been several intrauterine operations. The drug abortion has gastrointestinal reactions such as nausea, vomiting, abdominal pain, diarrhea, etc. It may also cause side effects such as prolonged bleeding and excessive bleeding, so the drug abortion must be performed in a medical institution with regular resuscitation conditions, and if necessary, the operation to clear the uterus. After a medical abortion, it is recommended to rest in bed for 1 week and to review the gynecological transvaginal ultrasound after half a month. Pay attention to personal hygiene in daily life, bathing should be showered, avoiding tub baths and sitz baths to avoid infection caused by sewage entering the vagina. If abnormal manifestations such as lower abdominal pain, fever, cloudy and smelly leucorrhea occur after medical abortion, you should go to the hospital for consultation and treatment in time.
