Dosing shown for moderate to severe infection due to susceptible gram-positive organisms in children and adolescents with normal kidney function. For guidance on antimicrobial choice, refer to UpToDate topic on treatment of invasive Staphylococcus aureus in children or other related infections. Dose adjustment recommendations for children with impaired kidney function are provided in Lexicomp daptomycin drug information included with UpToDate. Experience with daptomycin in children is limited; consultation with an infectious diseases expert may be appropriate.

IV: intravenously.
* Doses based on actual (total) body weight may be rounded to nearest 10 mg depending on local practice and administered once every 24 hours. Further studies are needed to evaluate the appropriateness of daptomycin dosing by total body weight in children and adolescents who are obese (ie, body mass index >30 mg/m²); closer monitoring for toxicity may be warranted in such cases.
