Answer

Topical antibiotic therapy is useful for localized infections; however, systemic treatment is preferred for recurrent or widespread infections. The agent of choice is penicillin G if group A streptococci is the known infectious organism. Use erythromycin or a semisynthetic penicillin (eg, nafcillin, oxacillin, dicloxacillin) if S aureus is a possible cause. Hospitalization and use of intravenous antibiotics are indicated in cases of invasive infection (eg, osteomyelitis). Perform urinalysis and closely observe patients for symptoms for at least 7 weeks after treatment in endemic areas because systemic antibiotic treatment does not prevent postinfectious glomerulonephritis after a cutaneous infection with nephritogenic M strains of streptococci.
