Little information is available on the relative tolerability of ceftaroline versus other cephalosporins in clinical practice. We sought to compare adverse drug reactions (ADRs) associated with ceftaroline with those associated with ceftriaxone in hospitalized patients. Materials and Methods: This was a retrospective, single-center matched cohort (according to age, indication, and duration) study of patients treated with ceftaroline or ceftriaxone at the VA St Louis Health Care System between 29 October 2010 and 28 March 2017, to compare rates of ADRs between the agents. Patients included received ≥2 doses of either medication to treat osteomyelitis, acute bacterial skin and skin structure infection, blood stream infection, pneumonia, infective endocarditis, septic arthritis, prosthetic joint infection, or empyema. The primary and secondary outcomes were the composite of any ADR during therapy and any ADR leading to premature discontinuation of therapy. The ADRs evaluated included rash, neutropenia, acute kidney injury, eosinophilia, thrombocytopenia, transaminitis, and hyperbilirubinemia. Results: After matching, 50 patients per group were included and analyzed. An ADR occurred in 20% (10 of 50) of patients treated with ceftriaxone and 16% (8 of 50) of those treated with ceftaroline (P =. 60). Two percent (1 of 50) of those treated with ceftriaxone and 16% (8 of 50) treated with ceftaroline had therapy discontinued owing to an ADR (P =. 03). The most common ADR was eosinophilia (3 of 50) in the ceftriaxone group and rash (5 of 50) in the ceftaroline group. Ceftaroline therapy was identified as an independent risk factor for an ADR requiring premature discontinuation (odds ratio, 10.2; 95% confidence interval, 1.19-87.8; P =. 03). Conclusions: Although there was no difference in the rates of ADRs between patients in the ceftriaxone and ceftaroline groups, significantly more ceftaroline-treated patients required premature discontinuation.
