Efficacy of a low dose of cefotaxime in serious chest infections.

Abstract

The optimal antibiotic dosage in serious chest infections is not established and commonly used regimens may well be excessive. We have compared the efficacy of a low dose of cefotaxime (2 g every 12 h) with a more usual dose (2 g every 8 h) in a prospective, randomized study of the treatment of chest infections in the seriously ill.
