Treatment of Acute Pharyngitis When a Viral Cause Is Likely and Antibiotics Are Not Indicated
Most sore throats have a viral origin. When clinical scoring and rapid testing suggest bacterial infection is unlikely, the management approach differs meaningfully from cases where antibiotics are warranted.
Clinical scenario
Acute pharyngitis of probable viral aetiology: none or one Centor criterion present and/or a negative rapid antigen detection (Strep A) test.
In this setting there is no indication for antibiotic therapy. Clinical practice guidelines and expert recommendations agree that, with one or no Centor criterion, neither further testing nor antibiotic prescribing is necessary.
Treatment approach
Management centres on symptomatic relief using analgesics and anti-inflammatory agents, together with supportive self-care measures including rest, adequate fluid intake, and avoidance of irritants.
The full structured regimen — specific agents, selection guidance, and step-by-step clinical detail — is available in the complete protocol below.
