Commonly used abortifacients in clinical practice include drugs such as mifepristone and misoprostol, and patients should use the drugs as prescribed by their doctors. The main function of mifepristone is to counteract progesterone, cortisol, and androgens, and it can terminate pregnancy by binding to progesterone receptors in the endometrium. Mifepristone alone cannot cause contractions, and without strong contractions, the dead embryo cannot be easily expelled from the body; it usually needs to be used in conjunction with misoprostol. In addition, before taking abortifacient drugs, an ultrasound should be done to check the location of the gestational sac, and it should only be taken after ectopic pregnancy has been ruled out. Clinical advice in the use of mifepristone and misoprostol should go to a regular hospital, under the guidance and advice of a doctor, do not take on their own.
