What is the recommended treatment for acute viral pharyngitis?

Treatment of Acute Viral Pharyngitis

Acute viral pharyngitis should be managed with symptomatic treatment only, as antibiotics are not indicated for viral infections. 1, 2

Diagnosis and Assessment

Before determining treatment, it's essential to distinguish between viral and bacterial pharyngitis:

• Viral pharyngitis indicators:

  • Presence of cough, rhinorrhea, hoarseness, oral ulcers
  • Absence of tonsillar exudates
  • Diffuse symptoms rather than focused throat pain
  • Often occurs in an epidemic context 1, 2

• Clinical assessment tools:

  • Centor Criteria can help assess likelihood of bacterial (GAS) pharyngitis:
    • Tonsillar exudates
    • Tender anterior cervical lymph nodes
    • Lack of cough
    • Fever 2
  • Patients with 0-1 Centor criteria are unlikely to have GAS infection and don't require testing or antibiotics 2

Recommended Treatment for Viral Pharyngitis

Symptomatic Relief (First-line approach)

• Analgesics/antipyretics:

  • Acetaminophen or NSAIDs for moderate to severe symptoms or fever control 1, 2
  • Avoid aspirin in children due to risk of Reye syndrome 1

• Topical remedies:

  • Warm salt water gargles (though limited detailed studies exist) 1
  • Cold liquids, ice chips, and gargling with cold water 2
  • Various topical agents including rinses, sprays, and lozenges containing topical anesthetics (ambroxol, lidocaine, benzocaine) may provide temporary relief 1
  • Note: Lozenges may pose a choking hazard for young children 1

What to Avoid

• Antibiotics:

  • Not recommended for viral pharyngitis as they provide no benefit 1
  • Unnecessary antibiotic use contributes to antimicrobial resistance 3

• Corticosteroids:

  • Not recommended for treatment of acute pharyngitis due to limited efficacy data and potential adverse effects 1

Special Considerations

• Children under 3 years:

  • Testing for GAS pharyngitis usually not indicated as streptococcal pharyngitis is uncommon in this age group 1
  • Focus on symptomatic relief appropriate for age 1

• When to reassess:

  • If symptoms persist beyond 7-10 days
  • If symptoms worsen significantly
  • If high fever develops or persists
  • If difficulty swallowing or breathing occurs 1, 2

Prevention Measures

• Hand hygiene
• Avoiding close contact with infected individuals
• Not sharing utensils or drinks 2

Key Pitfalls to Avoid

1. Prescribing antibiotics for viral pharyngitis - Most cases of pharyngitis (approximately 90% in adults) are viral and self-limited 3
2. Inadequate pain management - Proper analgesic dosing is important for patient comfort
3. Missing bacterial infection - Consider testing if multiple Centor criteria are present
4. Failing to provide adequate hydration advice - Maintaining hydration is crucial for recovery

Remember that viral pharyngitis is self-limiting, and treatment should focus on symptom relief while the infection runs its course.
