Anti-inflammatory drugs for medication abortion can normally be taken for 3-5 days without further intake. Because there is no operation of the uterine cavity in a medication abortion, if it is a one-time clean abortion, the damage to the woman is also relatively small, so it will not cause inflammatory infections. The drug abortion is suitable for pregnancies within 49 days of menopause. Before the drug abortion, preoperative examinations should be routinely performed, such as liver and kidney function tests, ultrasound examinations and inquiries about the physical condition. If there is no contraindication to taking the medication, the abortion can be performed. Before taking the medication, the patient should have an empty stomach and be observed in the hospital to see if the pregnancy tissue and the meconium tissue are complete.
