Most cephalosporins can be taken by pregnant women. The U.S. Food and Drug Safety Administration categorizes drugs into five classes: A, B, C, D and X. One of these, class B, is one that has not been found to have a teratogenic effect in animal studies, but lacks a control for pregnant women. Most cephalosporin antibiotics belong to class B. Pregnant women can take cephalosporin antibiotics appropriately when they need to use antibiotics and have no contraindications. The use of cephalosporin antibiotics in pregnant women need to have a clear indication for the use of drugs, the use of drugs to choose the clinical conclusions are more certain, try to avoid the use of new cephalosporin antibiotics. If the condition permits, try not to use in early pregnancy, delayed to the mid-pregnancy or late pregnancy medication. Cephalosporin antibiotics may cause allergic reactions, pregnant women should be careful with medication, previous cephalosporin antibiotics or penicillin allergy is prohibited for pregnant women. Pregnant women need to use drugs under the guidance of a professional doctor, not private abuse of drugs, so as not to cause adverse reactions to pregnant women, the fetus.
