that involve specific sites (e.g., face, hands, genitalia); and that occur in children and older adults or in those who have significant comorbid illness or immunosuppression.32 In uncomplicated cellulitis, five days of treatment is as effective as 10 days.33 In a randomized controlled trial of 200 children with uncomplicated SSTIs primarily caused by MRSA, clindamycin and cephalexin (Keflex) were equally effective.34, Inpatient treatment is necessary for patients who have uncontrolled infection despite adequate outpatient antimicrobial therapy or who cannot tolerate oral antibiotics (Figure 6).
