Treatment of Pediatric Sore Throat
Ibuprofen or paracetamol (acetaminophen) are the first-line treatments recommended for relief of acute sore throat symptoms in children, with ibuprofen showing slightly better efficacy as both an analgesic and antipyretic. 1
Symptomatic Treatment
Pain Management
First-line medications:
Benefits of ibuprofen vs. paracetamol:
- Longer duration of action (6-8 hours vs. 4 hours)
- More effective as an antipyretic
- At least as effective as an analgesic 2
Additional symptomatic measures:
- Warm salt water gargles for children old enough to cooperate
- Throat lozenges (for children old enough to safely use them)
- Adequate hydration 3
Diagnostic Approach
When to Suspect Bacterial Pharyngitis
Use the Centor Criteria to assess likelihood of Group A Streptococcal (GAS) infection 3:
- Tonsillar exudates
- Tender anterior cervical lymph nodes
- Lack of cough
- Fever
- 0-2 criteria: Unlikely to be GAS, no testing needed
- 3-4 criteria: Testing recommended with rapid antigen detection test (RADT) and/or throat culture 3
Testing Recommendations
- Clinical scoring systems and rapid tests help target appropriate antibiotic use 1
- A strategy using clinical scores alone may lead to higher antibiotic use compared to using rapid tests or a combination of clinical scores and rapid tests 1
Antibiotic Treatment
When to Use Antibiotics
Antibiotics should only be prescribed when:
- Positive rapid strep test or throat culture
- High clinical suspicion based on Centor criteria
- Not recommended for likely viral pharyngitis (those with cough, rhinorrhea, hoarseness, oral ulcers) 3
First-Line Antibiotic Options
If bacterial pharyngitis is confirmed:
Amoxicillin:
- 50 mg/kg once daily (maximum 1000 mg) OR
- 25 mg/kg twice daily (maximum 500 mg per dose)
- Duration: 10 days 3
Penicillin V:
- Children: 250 mg 2-3 times daily
- Adolescents: 500 mg 2-3 times daily
- Duration: 10 days 3
For Penicillin-Allergic Patients
- Cephalexin: 20 mg/kg twice daily (maximum 500 mg per dose) for 10 days
- Clindamycin: 7 mg/kg three times daily (maximum 300 mg per dose) for 10 days
- Azithromycin: 12 mg/kg once daily (maximum 500 mg) for 5 days 3, 4
Important Considerations
- Complete the full antibiotic course (10 days for most antibiotics, 5 days for azithromycin) to prevent complications like acute rheumatic fever 3
- The 10-day duration for beta-lactams is critical for preventing rheumatic fever and ensuring bacterial eradication 3
Special Considerations
When to Consider Tonsillectomy
Consider tonsillectomy for recurrent tonsillitis based on the Paradise criteria 3:
- ≥7 well-documented, adequately treated episodes in the preceding year, OR
- ≥5 such episodes in each of the preceding 2 years, OR
- ≥3 such episodes in each of the preceding 3 years
When to Refer/Hospitalize
A child with sore throat and toxic appearance may have diphtheria or parapharyngeal/retropharyngeal abscess and should be hospitalized immediately 5
Corticosteroids
A single dose of corticosteroids (e.g., dexamethasone) may benefit children with severe symptoms or high Centor scores when used in conjunction with appropriate treatment 1
Common Pitfalls to Avoid
- Overuse of antibiotics: Only 15-36% of children with sore throat have pharyngitis caused by GAS, yet antibiotics are prescribed in over 50% of cases 6
- Inadequate testing: Perform appropriate testing before prescribing antibiotics 6
- Using antibiotics for viral pharyngitis: Antibiotics should not be used in patients with likely viral pharyngitis or those with low Centor scores (0-2) 3
- Incomplete antibiotic courses: Ensure the full course is completed to prevent complications 3
- Inadequate pain management: Pain control is essential for the child's comfort and ability to maintain hydration 1, 2
By following these evidence-based recommendations, clinicians can effectively manage pediatric sore throat while minimizing unnecessary antibiotic use and ensuring appropriate symptom relief.
