1To decrease risk of toxicity, try to keep treatment duration to <5-7 days if patient is responding to therapy. Once-daily dosing is as effective (and no more/less toxic) as multiple-daily dosing.
2Optimal dose is the initial IV adult dose of antibiotic for empiric therapy for HAP/VAP in patients with risk factors for MDR pathogens as recommended by the American Thoracic Society (ATS) and the Infectious Diseases Society of America (IDSA) in: Management of adults with hospital-acquired and ventilator-associated pneumonia: 2016 clinical practice guidelines.
