Reproduction studies have been performed in pregnant mice given Cefotaxime intravenously at does up to 1200 mg/kg/day (0.4 times the recommended human dose based on mg/m2) or in pregnant rats when administered intravenously at does up to 1200 mg/kg/day (0.8 times the recommended human dose based on mg/m2). No evidence of embryotoxicity or teratogenicity was seen in these studies. There are not well-controlled studies in pregnant women. Because animal reproductive studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
Cefotaxime is excreted in human milk in low concentrations. Caution should be exercised when Cefotaxime is administered to a nursing woman.
