It is very difficult for pregnant mothers to keep from getting sick during the tenth month of pregnancy, and carrying on will harm the health of mother and baby, and taking the wrong medicine will be even more troublesome. The most important factors for the adverse effects of drugs on the fetus are the nature of the drug itself, the dose of the drug, the duration of the drug, the route of administration, the affinity of the fetus and the newborn for the drug, and most importantly, the gestational age when the drug is administered. Because of the different pharmacological effects of drugs on the mother and the fetus, the use of drugs during pregnancy requires caution. It is best to use medication during pregnancy after consulting a doctor. If the potential risk of the disease to the fetus is greater than the risk of the drug to the fetus, it is important to treat the disease with drugs in a timely manner, and to choose drugs that are relatively safe during pregnancy and prohibit experimental use of drugs during pregnancy. Different drugs have different degrees of danger to pregnant women: According to the U.S. Food and Drug Administration (FDA) report on the different teratogenic effects of drugs on humans, drugs are classified into 5 levels A, B, C, D and X according to their degree of danger to the fetus. You should read the instructions of the drugs before taking them. Regular drugs will indicate the drug classification and give you the corresponding advice. Class A: Drugs used during early pregnancy have not been clinically observed to be harmful to the fetus, and their risk is relatively low. Class B: No harm to fetus was observed in animal studies, but there is a lack of clinical control observation data, or harm to fetus was observed in animal studies, but clinical control observation failed to confirm. Category C: Harmful to fetus was observed in animal testing, but clinical control observations were not available, or both animal testing and clinical control observations were not available. These drugs should be used only after the physician has evaluated their advantages and disadvantages. >Category D: There is some clinical information that the drug is harmful to the fetus, but there is a strong clinical need and there is no alternative drug. They should be used only when necessary (in severe cases of pregnant women). Class X: Evidence of fetal abnormality is clearly found in the results of animal experiments and clinical data. Use is prohibited for women who are preparing to conceive or are pregnant. Some domestic proprietary Chinese medicines, herbal medicines, supplements and health products may not have this label. Please make sure you do not take these herbal medicines without confirmation, and consult a doctor before deciding. We would like to take this opportunity to urge you to use good contraception, plan your pregnancy, have a proper attitude when you get pregnant, understand the risks of pregnancy, actively prepare for the risks, don’t over panic, and learn to enjoy your pregnancy.
