Patient's question:
Hello, I am two months pregnant. Recently, there have been many class reunions and family gatherings, about five in total. It's unavoidable that many people smoke at these events, and I'm also a bit down with a cold. I'm worried about the impact on the fetus. Actually, no one in my family smokes. Is there any danger to the fetus?Regarding the definition of a, if the fetus is, will it lead to a miscarriage, or will it continue to grow in the womb? Does an ultrasound check reveal whether the fetus is normal?
Doctor's answer:
Hello: According to your situation, if you have not been drinking or smoking, there should be no problem. Clinical observations and animal experiments have shown that many drugs can cause fetal malformations or may lead to deformities. Especially during the first three months of pregnancy, the fertilized egg is in the stage of successive differentiation of various organs and tissues, making it susceptible to drug effects that can hinder the development of certain organs and result in deformities. For the sake of eugenics and improving population quality, it is best to use as few drugs as possible or avoid them altogether during the entire pregnancy. The following drugs should be avoided or used in reduced amounts to prevent teratogenesis.(1) Antibiotics: Tetracycline, oxytetracycline, kanamycin, gentamicin, streptomycin, chloramphenicol, erythromycin, rifampicin, tobramycin, sulfonamides, etc.
(2) Vitamins: Vitamins A, D, K, B6, etc.
(3) Hormones: Diethylstilbestrol, progesterone, testosterone, corticosteroids, oral contraceptives, etc.
(4) Analgesics and antipyretics: Aspirin and its preparations, phenacetin, acetaminophen, etc.
(5) Sedatives and antipsychotic drugs: Phenobarbital, sodium phenytoin, diazepam, methaqualone, librium, chlorpromazine, haloperidol, lithium carbonate, meprobamate, chloromethiazole, etc.
(6) Antihypertensive and diuretic drugs: Reserpine, magnesium sulfate, bromhexine, hydrochlorothiazide, etc.
(7) Hypoglycemic drugs: Tolbutamide, chlorpropamide, glyburide, insulin, etc.
(8) Antimalarial drugs: Chloroquine, quinine, proguanil, etc.
(9) Antitumor drugs: Methotrexate, cyclophosphamide, busulfan, 6-mercaptopurine, colchicine, chlorambucil, etc.
