Doses are expressed in terms of the equivalent amount of cefotaxime; 1.05 g of cefotaxime is equivalent to about 1 g of cefotaxime. It is usually given in doses of 2 to 6 g daily in to 2 to 4 divided doses to adults. In severe infections up to 12 g may be given daily by intravenous route in up to 6 divided doses; pseudomonal infections usually require more than 6g daily, but a cephalosporin with greater antipseudomonal activity, such as ceftazidime, is preferrable.
