Treatment is aimed at providing adequate antistreptococcal antibiotic levels for at least 10 days.

Treat patients who have scarlet fever with a standard 10-day course of oral penicillin VK or erythromycin. Patients can also be treated with a single intramuscular injection of penicillin G benzathine. These regimens may prevent acute renal failure if antibiotics are initiated within 1 week of the onset of acute pharyngitis. First-generation cephalosporins may also be used. Erythromycin should be considered in patients allergic to penicillin. Tetracyclines and sulfonamides should not be used.
