Medication abortion is a remedy to terminate the failure of contraception with medication. The majority of abortion pills in clinical practice are mifepristone combined with misoprostol, abortion pills taken for one day usually means taking mifepristone for one day. Mifepristone is a steroidal anti-progestational agent that has some adverse effects on the embryo, so the baby is not recommended after one day of abortion pills. Since patients have already taken mifepristone orally, taking it may lead to fetal malformations, such as urethral cleft in male babies or masculinization of the genitals in female babies. Some patients do not react after taking the pill, while others may experience nausea, vomiting or vaginal bleeding, or even abdominal pain and vaginal bleeding followed by expulsion of the embryo within a short period of time after taking mifepristone. Therefore, after taking the abortion pill for one day, it is mostly not recommended for pregnant women to continue the pregnancy and to continue to take it together with Misoprostol for medication abortion. It is important for women to consider and decide before having a medication abortion to avoid the situation of wanting to continue the pregnancy after taking the medication, as there is no way to save the embryo once it is stunted and miscarried due to the action of the medication. The abortion should also be performed in a medical institution with regular resuscitation conditions, and must be used under the supervision of medical personnel, with close observation of clinical bleeding, whether there are adverse drug reactions, and whether the tissue is completely discharged, to ensure the safety of the pregnant woman.
