Which antibiotics are commonly used for streptococcal pharyngitis in non-allergic patients?

• A. Penicillin V or Amoxicillin (and Amoxicillin-clavulanate in some cases).
• B. Azithromycin only.
• C. No antibiotics; supportive care only.
• D. Clindamycin monotherapy.

Answer: (A)

Streptococcal pharyngitis is best treated with a penicillin-class antibiotic in patients who are not allergic, because group A Streptococcus is universally susceptible to penicillin and this choice reliably eradicates the infection while helping prevent rheumatic fever. Penicillin V is the traditional oral option, and amoxicillin is a convenient alternative—often preferred in children for its palatability and simpler dosing. Amoxicillin-clavulanate adds broader beta-lactamase coverage, which isn’t needed for uncomplicated GAS pharyngitis and carries a higher risk of side effects and antibiotic overuse. Therefore it’s reserved for specific situations where broader coverage is truly indicated. Azithromycin or other macrolides are not ideal as a sole choice for GAS pharyngitis due to concerns about rising resistance and less consistent effectiveness. No antibiotics would miss the opportunity to prevent rheumatic complications. Clindamycin is not first-line because of higher rates of adverse effects, including C. difficile infection, and is not necessary when penicillin remains appropriate. So, the best approach is penicillin V or amoxicillin, with amoxicillin-clavulanate only in particular, non-routine scenarios.
