Warning: smoking in the early pregnancy can cause heart defects in infants
are well known, and the adverse effects of some drugs on the fetus are often more concerned. In our side, there are many drugs, not only can cause embryo or fetal abortion, but also lead to fetal malformation, there are very serious consequences. Most of the side effects caused by these harmful drugs are third to fourteenth weeks after conception. This is the period of embryo development. This period is most likely to cause disability and teratogenicity.
how to prevent the occurrence of drug-induced teratoma is a problem that pregnant women and families need to pay attention to. Due to misuse of drugs during pregnancy, contact with chemicals or improper medication, the fetal organs are often abnormal in shape and structure. It has been reported that 330 thousand malformed newborns have been investigated and found that more than 10000 cases have been caused by improper medication. This is indeed a worrying problem, which has posed a serious threat to eugenics.
there are many kinds of drugs that can easily lead to fetal malformation from the classification of drugs:

Streptomycin and kanamycin can cause congenital deafness and kidney damage. Some fetuses are very sensitive. Even if they are used in small quantities, serious consequences may occur. Chloramphenicol can cause fetal skeletal function inhibition, resulting in neonatal pulmonary hemorrhage.
3, the amount of vitamin A is also unsafe
there are many people think vitamin is health care medicine, how much is safe to take, in fact not. Excessive vitamin use can also cause fetal malformation, the drug has a safe range, can not be used at random, in general, pregnant women take vitamin A daily allowance is 3300 international units, vitamin A ester is 5000 international units, can not be overdose.

in the early pregnancy due to reactive vomiting, many pregnant women often take some antiemetic drugs to relieve pain. In fact, some town emetic drugs also have teratogenic risk. Such drugs include promethazine, chlorpromazine, three fluazine, chlorobenzazine, etc., which can cause fetal heart development to be obstructed and suffer from congenital heart disease. People think that Chinese medicine is very safe, in fact, this view is also wrong, such as the traditional Chinese medicine Pinellia ternata with the effect of antiemetic, animal experiments have the side effects of fetal malformation. Drugs such as
