Peritonsillar Abscess Treatment Guidelines

Primary Treatment Approach

• The American Academy of Pediatrics recommends amoxicillin-clavulanic acid as an alternative regimen for peritonsillar abscess treatment, providing both aerobic and anaerobic coverage 2
• The Infectious Diseases Society of America suggests clindamycin monotherapy as an alternative option, covering both streptococci and anaerobes 3

Treatment Failure and Escalation

• The American College of Physicians advises that hospitalization is indicated if there is no clinical improvement within 72 hours of appropriate antibiotic therapy, highlighting the importance of close monitoring 1

Antibiotic Selection

• The guideline recommends against using doxycycline as monotherapy for peritonsillar abscess due to its lack of sufficient anaerobic coverage, which is essential for treating these polymicrobial infections 1
