What is the standard dosage of azithromycin in children?
Show answer and explanation
Correct answer: B. 15 mg/kg
- A. 10 mg/kg is the standard Day 1 loading dose. FDA labeling specifies 10 mg/kg day 1 (max 500mg), then 5 mg/kg days 2-5 (max 250mg). See flag on option B.
- B. ⚠️ FLAG — The peer-recall source lists 15 mg/kg as the exam answer. However, current FDA-approved azithromycin pediatric dosing is 10 mg/kg on Day 1 (max 500mg), then 5 mg/kg Days 2-5 (max 250mg), for a total course of 30 mg/kg. The 15 mg/kg figure does not match standard prescribing information.
- C. 20 mg/kg is used for single-dose azithromycin in specific indications (trachoma, gonorrhea prophylaxis) — not the standard pediatric antibiotic regimen.
- D. 5 mg/kg is the MAINTENANCE dose (Days 2-5) in the standard 5-day regimen — not the primary dose.
