Some drugs do have a certain impact on the fetus, and some harmful substances in some drugs can enter the fetus through the mother\’s body and affect fetal development.
For example: aspirin can cause fetal skeletal malformations; protons can cause congenital heart disease in children; tetracycline can cause fetal skeletal malformations and yellowing of deciduous teeth; rhubarb can cause miscarriage; streptomycin and kanamycin can damage fetal hearing, mental and kidney Function; some sulfa drugs can also cause aggravation of jaundice; hormone drugs can induce malformations.
The reason why the above-mentioned drugs cause direct damage to the fetus is that after the mother takes these drugs, the drugs can enter the fetus through the placenta, and their concentration is the same as that in the mother\’s blood, and then distributed throughout the fetus\’s body. This system works so that the fetus cannot withstand the attack of teratogenic drugs, especially in the first trimester.
Therefore, pregnant women must seek medical treatment if they are sick and take medicine as prescribed.
