Guiding opinions:

Drugs may affect the fetus, but not all drugs affect the fetus. In order to find out which drugs have teratogenic effects on the fetus, relevant experts have done a lot of animal experiments and long-term clinical observation, and summed up certain rules. According to the degree of possible dangers and adverse reactions of drugs to the fetus, it is divided into five grades, and the drugs can be selected according to the situation.

Grade A has been proved to have no adverse effects on human fetuses and is the safest, such as antithyroid tablets.

Grade B is evidence that it is harmless to the fetus, and animal experiments may be harmful to the fetus, such as penicillin, cefazolin (cephalosporin V), ceftriaxone (ceftriaxone), spectinomycin (spectinomycin), erythromycin, lincomycin (clindamycin), sulfamethoxazole (sulfamethoxazole), ethambutol and metronidazole. Magnesium sulfate in antihypertensive drugs; Insulin in hypoglycemic drugs; Prednisone in hormones; And indomethacin.

Class c can't rule out hazards. Animal experiments may be harmful to the fetus (teratogenic or fatal), but they have not been fully studied in humans, or the benefits to pregnant women outweigh the harm to the fetus. Such as gentamicin, tobramycin, spiramycin, chloramphenicol, ciprofloxacin, trimethoprim, isoniazid (remifentanil) and so on. Among antihypertensive drugs, propranolol, sodium nitroprusside and nimodipine. Antipyretic aspirin; Aminophylline, ephedrine and salbutamol in the treatment of asthma; Dexamethasone in hormone; And heparin, rabies vaccine, plague vaccine, etc.

Grade D is clear evidence that it is harmful to human fetus, but the benefits of treating pregnant women's diseases obviously exceed the harm of drugs. For example, when pregnant women are seriously ill and other safe drugs are ineffective, they can be used, such as streptomycin, kanamycin, tetracycline, oxytetracycline and minocycline hydrochloride in anti-infective drugs; Captopril in antihypertensive drugs; Lumina and diazepam in nervous system drugs; Diuretic hydrochlorothiazide; And potassium iodide, warfarin and anticancer drugs.
