In a pediatric narcotic overdose, what is the initial Narcan dose and route?

• A. 1 mg IM/IN
• B. 0.5 mg IV/IO
• C. 2 mg IV/IO
• D. 0.25 mg IM/IN

Answer: (B)

The key idea is to reverse opioid-induced respiratory depression quickly while using a dose that is safe for a child. Giving naloxone through IV or IO provides the fastest onset, which is crucial in a pediatric overdose where every moment counts for ventilation. A starting bolus of 0.5 mg via IV or IO is chosen because it is large enough to begin reversing the opioid effects promptly but not so large that it risks precipitating abrupt withdrawal or excessive sympathetic stimulation. If there’s incomplete reversal, clinicians can titrate with small, repeat doses and reassess. Intramuscular or intranasal administration tends to have slower, less predictable absorption, which is why they’re less favored as the initial dose in a life-threatening pediatric overdose. A much larger initial dose could cause unnecessary complications, while too small a dose may not rapidly restore breathing.
