For non-severe community-acquired pneumonia in a healthy child, what is first-line antibiotic?

• A. Azithromycin
• B. Levofloxacin
• C. Ceftriaxone
• D. Amoxicillin

Answer: (D)

For non-severe pneumonia in a healthy child, amoxicillin is the best first-line choice because the most likely pathogen in this scenario is Streptococcus pneumoniae. Amoxicillin effectively treats pneumococcus, is safe for children, and can be given by mouth, which fits outpatient management of mild disease. Choosing this narrow-spectrum agent minimizes unnecessary exposure to broader antibiotics and helps combat resistance while still targeting the common bacteria responsible. If penicillin allergy or suspicion of an atypical pathogen is present, a macrolide like azithromycin might be considered, but it’s not the preferred first-line in uncomplicated cases. Levofloxacin is generally avoided in children due to potential joint and tendon effects, and ceftriaxone is reserved for inpatient treatment or more severe illness.
