The effect of medication on the fetus during pregnancy needs to be determined by the safety factor of the medication. Drugs can usually be categorized into Class A, Class B, Class C, Class D, and Class X. Each type of drug has a different effect on the fetus.
1. Class A: Usually vitamins, such as vitamin B, vitamin C, and normal range amounts of vitamin A. This is safer and has less effect on the fetus.
2. Class B: mainly includes penicillin or cephalosporin antibiotics, which also have little effect on the fetus. However, pregnant women who are allergic to these drugs should be prohibited.
3. Class C: mainly refers to quinolone antibiotics or anti-epileptic drugs, this class of drugs may cause miscarriage and so on.
4. Class D: usually harmful to the fetus, such as tetracycline, antitumor drugs. This type of drug may lead to fetal dysplasia or hearing loss.
5. Class X: Class X drugs are absolutely prohibited drugs, such as sex hormone drugs, large doses of vitamin A, etc., which can easily lead to developmental deformities in the child.
Therefore, it is generally not recommended for pregnant women to take medication on their own during pregnancy. If you are suffering from a disease, it is recommended that you go to the hospital and use the medication under the guidance of the doctor.
