Treatment of Pneumonia in Children

First-Line Antibiotic Selection

The American Academy of Pediatrics recommends amoxicillin as the first-line treatment for community-acquired pneumonia in children, given orally at 90 mg/kg/day divided into 2-3 doses for 5 days 1, 2
For children under 5 years, oral amoxicillin is the preferred first-line agent because it effectively targets Streptococcus pneumoniae and Haemophilus influenzae, the most common bacterial pathogens causing severe disease in this age group 1, 2

For non-severe pneumonia, the World Health Organization recommends oral amoxicillin twice daily for 3-5 days 1
Co-trimoxazole may be used as an alternative in some settings, though it is not first-line treatment 1, 3

The American College of Chest Physicians defines treatment failure as a child who develops signs warranting immediate referral or who does not have a decrease in respiratory rate after 48-72 hours of therapy 1
If first-line agent failure is confirmed and no indication for immediate referral, switch to high-dose amoxicillin-clavulanate with or without an affordable macrolide for children over 3 years of age 1

In HIV-prevalent areas or HIV-infected children, the Centers for Disease Control and Prevention recommends first-line treatment remains amoxicillin for non-severe pneumonia, regardless of co-trimoxazole prophylaxis status 2, 3, 4
In malaria-endemic regions, the World Health Organization recommends prescribing both first-line therapies for malaria and pneumonia if pneumonia is diagnosed but malaria cannot be excluded 3, 4

The American Academy of Pediatrics recommends oxygen therapy to maintain oxygen saturation >92% with supplemental oxygen as needed 2
Elevate the head of the bed 30-45 degrees to improve breathing 5
Antipyretics and analgesics can help keep the child comfortable and assist with coughing 2
Gentle nasal suctioning may be performed as needed 5
Avoid chest physiotherapy as it is not beneficial and should not be performed in children with pneumonia 2, 5

Do not use cefixime in children under 5 years as an alternative regimen 5
Do not prescribe broader-spectrum antibiotics empirically without first trying amoxicillin, as this contributes to antimicrobial resistance 1
Do not assume treatment failure before 48-72 hours unless the child develops signs warranting immediate referral 1

The British Thoracic Society guidelines for pediatric community-acquired pneumonia (CAP) state that antipyretics and analgesics can be used to keep the child comfortable and to help coughing, but do not recommend specific antitussive agents as part of pneumonia management 6, 7
Major pediatric pneumonia guidelines from the Pediatric Infectious Diseases Society, Infectious Diseases Society of America, and WHO focus exclusively on antibiotic therapy and supportive care (oxygen, hydration) without recommending cough suppressants 8

For children under 5 years, the American Academy of Pediatrics recommends oral amoxicillin 90 mg/kg/day divided into 2 doses as first-line treatment 6, 7
For children 5 years and older, the Infectious Diseases Society of America recommends macrolide antibiotics (azithromycin, clarithromycin) as first-line empirical treatment due to higher prevalence of Mycoplasma pneumonia 6, 7
For severe pneumonia requiring hospitalization, the Pediatric Infectious Diseases Society indicates IV antibiotics such as ampicillin, co-amoxiclav, cefuroxime, or cefotaxime are indicated 6, 8

The British Thoracic Society recommends maintaining oxygen saturation >92% with supplemental oxygen as needed 6, 7
The American Academy of Pediatrics suggests antipyretics (acetaminophen, ibuprofen) for fever and comfort 6, 7
The World Health Organization advises adequate hydration, with IV fluids at 80% basal levels if needed 6, 7
The American Thoracic Society recommends avoiding chest physiotherapy, which is not beneficial and should not be performed in children with pneumonia 6, 7
