Specific therapy for streptococcal infection is an important part of the therapeutic regimen. Throat cultures should be performed on patients, family members, and close personal contacts, and treatment should be provided for all patients found to be infected or colonized. Treat with oral penicillin G (250 mg qid for 7-10 d) or with erythromycin (250 mg qid for 7-10 d) for patients allergic to penicillin. This helps prevent nephritis in carriers and helps prevent the spread of nephritogenic strains to others.
