Executive summary

  • Assessment: Use FeverPAIN (preferred) or Centor score to determine likelihood of Streptococcal infection.
  • Stewardship: Most cases are viral. Antibiotics shorten duration by only ~16 hours. Limit use to high scores or vulnerable patients.
  • Quinsy (Peritonsillar Abscess): Unilateral swelling, trismus (cant open mouth), deviated uvula -> Urgent ENT Referral.

FeverPAIN Score (0-5)

  • Criteria: Fever (last 24h), Purulence (pus on tonsils), Attend rapidly (≤3 days), Inflamed tonsils (severe), No cough/coryza. (1 point each).
  • Score 0-1: No antibiotics. (13-18% Strep). Safety net.
  • Score 2-3: Delayed prescription (use if no better in 3-5 days).
  • Score 4-5: Immediate prescription (62-65% Strep).

Treatment Regimens

  • First Line: Phenoxymethylpenicillin (Penicillin V)
    • Adults: 500mg qds (or 1g bd) for 5-10 days. (10 days eradicates Strep better).
    • Children: Dosed by age (e.g., 250mg qds for 6-11 years).
  • Penicillin Allergy:
    • Clarithromycin: 250mg bd for 5 days.
    • Erythromycin: 250-500mg qds for 5 days (preferred in pregnancy).
