Adult Narcotic Overdose: Narcan dosing and monitoring.

• A. 0.1-0.5 mg
• B. 0.25-1 mg
• C. 0.5-2 mg
• D. 2-4 mg

Answer: (C)

The main idea is to reverse opioid-induced respiratory depression by titrating naloxone to the patient’s response. In adults, the safest and most effective approach is to give small, measured doses and repeat as needed until breathing improves, rather than delivering a large fixed dose all at once. A practical dosing range to achieve this balance is 0.5 to 2 mg per dose. This window allows enough naloxone to rapidly restore respiration in most adults, including those exposed to potent synthetic opioids, while reducing the risk of precipitated withdrawal, abrupt agitation, or sudden hemodynamic changes from a large initial dose. Administer IV when possible for the fastest effect, then reassess every 2–3 minutes and repeat dosing until respirations, oxygenation, and consciousness are adequate. After dosing, continuous monitoring is essential: watch breathing rate and depth, oxygen saturation, mental status, blood pressure, and heart rate. Be prepared to provide airway support and consider additional dosing or an infusion if the opioid effect wears off before the patient’s own respiration stabilizes, since some opioids have longer action than naloxone.
