Pediatric patients aged 1 day to 8 years presenting with respiratory depression from suspected opioid overdose should receive which initial Naloxone dosing?

• A. 0.5 mg IM/IN/IV/IO per administration
• B. 0.05 mg/kg IM/IN/IV/IO per administration
• C. 0.1 mg/kg IM/IN/IV/IO; do not exceed 0.5 mg per administration; may repeat every 2–3 minutes
• D. 1 mg/kg IM/IN/IV/IO per administration

Answer: (C)

The key idea is to reverse opioid-induced respiratory depression in children with a weight-based approach and to titrate the dose to effect. For a pediatric patient from birth to about 8 years old, the recommended initial naloxone dose is 0.1 mg per kilogram of body weight, given by any approved route (IM, IN, IV, or IO), with a maximum of 0.5 mg per administration. If there isn’t adequate improvement in respiratory status within 2–3 minutes, you repeat the same dose. This titration minimizes the risk of overshoot into withdrawal or abrupt hemodynamic changes while ensuring the patient begins breathing more effectively.

Why the other options aren’t as good fits: a fixed 0.5 mg per dose can be far too low for larger children when compared to a weight-based 0.1 mg/kg dose, making reversal unreliable; a dose of 0.05 mg/kg is undersized and may fail to reverse the overdose; a dose of 1 mg/kg is excessively high and increases the risk of adverse effects.
