Medication abortion is the use of drugs to achieve the effect of abortion, so it is called medication abortion. In fact, medication abortion and artificial abortion are the two most commonly used abortion methods in clinical practice. However, drug abortion may have more requirements for indications than artificial abortion. If a woman smokes for a long time or smokes a lot, or has heart, liver and kidney diseases, or has thyroid disease, diabetes, etc. or tumors, drug abortion is not suitable in these cases, because these are contraindications to drug abortion. Therefore, we must be careful when choosing whether to choose drug abortion. There are also drug abortion only during early pregnancy such as menopause 48-49 days, and the gestational sac is not large in the case of a higher success rate, but if the number of days is larger, and the gestational sac is also larger, the success rate will be lower, and often there will be a drug abortion incomplete situation.
