Once-daily ceftriaxone for skin and soft tissue infections

We prospectively compared once-daily administration of ceftriaxone with cefazolin given every 8 h for the treatment of skin and soft tissue infections. Thirty-one patients received cefazolin for a mean of 4.5 days, and 26 patients received ceftriaxone for a mean of 4.0 days. All patients had a satisfactory response. Adverse reactions were few and reversible. Ceftriaxone given as a single daily intramuscular injection is effective therapy for skin and soft tissue infections.
