• For uncomplicted community acquired pneumonia which is treated as an outpatient, high dose amoxicillin (80-90mg/kg/day) is the first-line antibiotic of choice.
• Macrolides and third-generation cephalosporins are acceptable alternatives, but are not as effective due to pneumococcal resistance and lower systemic absorption, respectivley.
• Hospitalization should be strongly considered for children younger than 2 months or premature due to an increased risk for apnea.
• Patients hospitalized only for pneumonia, should be treated with ampicillin while those who are septic should be treated with a combination of vancomycin along with a second- or third- generation cephalosporin.
