Answer

Therapy for streptococcal pharyngitis is aimed primarily at preventing nonsuppurative and suppurative complications and decreasing infectivity. A 10-day course of penicillin V 250 mg twice daily in children and 500 mg twice daily or 250 mg 4 times daily in adults is very effective. A single intramuscular injection of 1.2 million units of penicillin G benzathine can be administered in patients who weigh more than 27 kg; 600,000 units is used in patients who weigh less than 27 kg. Amoxicillin is equally effective and may be better tolerated in children.
