Treatment of Pneumonia in Children
Amoxicillin is the first-line treatment for community-acquired pneumonia (CAP) in children, with a recommended dose of 90 mg/kg/day in two divided doses for 5-7 days in most cases. 1, 2
Treatment Based on Severity and Setting
Outpatient Management (Mild-Moderate Pneumonia)
First-line therapy: Oral amoxicillin
Alternative options (for penicillin allergy):
Inpatient Management (Severe Pneumonia)
Fully immunized children:
- Ampicillin (150-200 mg/kg/day every 6 hours) or penicillin G (200,000-250,000 U/kg/day every 4-6 hours) 1
Not fully immunized or high local pneumococcal resistance:
- Third-generation cephalosporin: Ceftriaxone (50-100 mg/kg/day) or cefotaxime (150 mg/kg/day) 1
If MRSA suspected:
If Mycoplasma or Chlamydia pneumonia suspected:
- Add a macrolide (e.g., azithromycin) to β-lactam therapy 1
Age-Specific Considerations
Children <5 years
- Focus on coverage for Streptococcus pneumoniae with amoxicillin as first-line therapy 1, 2
- Amoxicillin is effective against the majority of pathogens causing CAP in this age group 1
Children ≥5 years
- Consider atypical pathogens (Mycoplasma pneumoniae, Chlamydia pneumoniae)
- Macrolide antibiotics may be used as first-line empirical treatment 1
- For azithromycin, the pediatric dose for CAP is 10 mg/kg on day 1, followed by 5 mg/kg on days 2-5 4
Monitoring and Follow-up
- Children treated at home should be reviewed if deteriorating or not improving after 48 hours 1
- Patients on oxygen therapy should have oxygen saturation checks at least every 4 hours 2
- Clinical improvement should be assessed within 48-72 hours, looking for:
- Decreased respiratory rate
- Reduced work of breathing
- Improved oxygen saturation
- Decreased fever
- Improved feeding 2
Important Considerations
- Oxygen therapy: Provide supplemental oxygen for patients with oxygen saturation ≤92% to maintain levels above 92% 1
- Hydration: If IV fluids needed, give at 80% of basal levels and monitor electrolytes 1
- Avoid unnecessary interventions:
Recent Evidence on Dosing and Duration
Recent high-quality evidence from the CAP-IT trial (2021) showed that lower-dose amoxicillin (35-50 mg/kg/day) was non-inferior to higher-dose (70-90 mg/kg/day), and 3-day treatment was non-inferior to 7-day treatment for most children 3. However, time to resolution of cough was slightly longer with the 3-day course, suggesting that the traditional 5-7 day course may still be preferable for symptom management 3, 5.
Common Pitfalls to Avoid
- Inappropriate antibiotic selection: Don't use broad-spectrum antibiotics when narrow-spectrum will suffice
- Inadequate dosing: Underdosing amoxicillin can lead to treatment failure, especially in areas with increasing pneumococcal resistance
- Overuse of macrolides: Reserve for suspected atypical pneumonia or as part of combination therapy
- Delayed transition to oral therapy: Switch from IV to oral antibiotics when there is clear clinical improvement 1
- Unnecessary hospitalization: Use severity assessment criteria to determine appropriate treatment setting
By following these evidence-based guidelines, clinicians can effectively manage pediatric pneumonia while minimizing antibiotic resistance and optimizing outcomes.
