Drug abortion is relatively safe, but not absolutely safe. The risks that may occur in medication abortion are mainly in the following aspects: 1, patients may have allergic reactions to medication, for example, patients can have mild allergic reactions such as nausea, vomiting, diarrhea, skin rash, and other life-threatening adverse reactions such as severe liver and renal function damage and anaphylactic shock, etc. 2, patients may have hemorrhage during medication abortion. The amount of vaginal bleeding during medication abortion exceeds the normal amount of menstrual bleeding, which is called hemorrhage. If the hemorrhage cannot be corrected in time, hemorrhagic shock can occur, which can endanger the patient’s life. When having a medication abortion, the patient must be observed in the hospital to see if there is any allergic reaction to the medication and if there is heavy bleeding. If this happens, it can be treated symptomatically in time.
