Other oral alternatives include doxycycline and the fluoroquinolones, which when dictated by cultures and sensitivities, may be used safely in children. 1ntravenous antimicrobials with activity against mixed flora such as ß-lactam/ß-lactamase inhibitor combinations, TMP/SMX plus clindamycin, and secondgeneration cephalosporins with anaerobic activity (e.g., cefoxitin) are suitable empiric choices for severe infections (References 56, 62). Broad-spectrum carbapenems should be reserved for treatment failure or drug-resistant isolates.Therapy duration will vary by the severity of injury, but it can range from 7-14 days for soft tissue infections to 3-6 weeks for involvement of the joints or bones
