Safety and Treatment Outcomes of Infants and Children Treated With Daptomycin: Six-Year Experience From a Pediatric Academic Medical Center

Daptomycin is a common treatment for serious infections caused by gram-positive bacteria in adult patients; however, data regarding its safety and efficacy in the pediatric population are limited. This was a retrospective chart review of adverse reactions and treatment outcomes associated with daptomycin use in children <13 years old who received at least 1 dose of daptomycin. At least 1 dose of daptomycin was received by 147 patients. Seventy-two patients received daptomycin for 5 or more days. New-onset loose stools on daptomycin initiation were reported for 14 (9.5%) patients, elevations in creatine kinase in 3 (2%) patients, and elevated aspartate transaminase and alanine transaminase in 13 (8.8%) and 9 (6.1%) patients, respectively. Two patients (1.4%) had daptomycin discontinued due to specific concerns for adverse drug reactions. Daptomycin was found to be safe and effective in this pediatric cohort that included young children and infants with a variety of types and severities of infections.
