Is miscarriage related to medication used before and during pregnancy?

Many patients who have had miscarriages have taken cold, cough or other medicines without knowing their pregnancy status. They are worried about whether their pre-pregnancy medications will harm the fetus. Is there any relationship between the medications used before and during pregnancy? Let me explain this to you.

Whether taking medicine in early pregnancy will have adverse consequences depends on the time, type and dosage of the medicine. The time of conception of the expectant mother can be calculated through the menstrual cycle. If the medicine is taken within two weeks of conception and no miscarriage occurs afterwards, it is theoretically considered that there is no effect on the fetus.

Because within two weeks of conception, the embryonic cells divide very quickly and pluridirectionally. If one cell is damaged, other cells can compensate. If the pregnant woman takes medicine at this time, if not many cells are damaged, it will not affect the development of the embryo. If it causes severe damage to the embryo or complete death, it will lead to spontaneous abortion. In other words, if the embryo survives, theoretically, it means that the fetus will not be disabled.

The Food and Drug Administration (FDA) of China classifies the safety of medications during pregnancy into five levels: A, B, C, D, and X. Currently, the clinical use of Western medicines in my country also refers to the FDA's safety classification of medications during pregnancy.

This safety classification is based on the results of animal tests and clinical trials, where both Class A and Class B drugs are considered safe for pregnant women and fetuses, such as penicillin, folic acid, vitamins, etc. In other words, if you take these drugs during pregnancy, there is no need to worry about the health of the fetus. In addition, Professor Li Yi pointed out that the dosage of the drug should also be considered as one of the criteria. If you only take one or two pills of the drug, it is really unfair to sentence the fetus to "death penalty".

From a clinical perspective, abortion itself has a very negative impact on women's health, especially reproductive health, both in the short and long term. Therefore, do not give up the fetus in your belly easily because you think you are "still young" or "there will be plenty of opportunities in the future."

If you get sick during pregnancy, receive X-rays or other conditions that are not good for the fetus, you must consult a professional doctor in detail and listen to the doctor's advice. If you are only taking certain medications, you should bring all the drug instructions to the doctor and ask the doctor to help analyze whether you should keep the fetus in the womb instead of easily choosing to terminate the pregnancy.
