Fifty-seven patients with bacterial meningitis were treated with once daily ceftriaxone. After an initial loading dose of 100 mg/kg, the patients received 80 mg/kg as a single daily dose. Etiologic agents included: Haemophilus influenzae type b, 37 (11 beta-lactamase-positive); Neisseria meningitidis, 11; Streptococcus pneumoniae, 6; Streptococcus pyogenes, 1; Haemophilus influenzae type f, 1; and Group B Streptococcus, 1. ⋯ The drug was well-tolerated and the major adverse effect seen was diarrhea in 20.4% of the patients. The diarrhea was mild and self-limited and did not necessitate discontinuation of the drug although it was frequently associated with alterations in the stool microbiologic flora. Based on this preliminary experience, ceftriaxone, when given in a single daily dose, appears safe and effective in the treatment of bacterial meningitis in nonneonatal infants and children.
