What is the maximum total dose of Naloxone in adult overdose protocols, regardless of route?

• A. Do not exceed 10 mg total regardless of route.
• B. Do not exceed 5 mg total.
• C. Do not exceed 20 mg total.
• D. There is no maximum limit.

Answer: (A)

Naloxone works by blocking opioid receptors to reverse respiratory depression caused by opioids, so the dose is given in small, carefully titrated steps until breathing improves. In adult overdose protocols, a practical safety ceiling is set: the total amount given across all routes should not exceed 10 mg. This limit helps balance effectively reversing the overdose with reducing the risk of precipitated withdrawal, agitation, hypertension, or other adverse effects that can come from too rapid or excessive reversal, especially in opioid-dependent patients. The cap applies regardless of how the drug is administered (IV, IM, intranasal), because the goal is to standardize safety across routes while still allowing titration to the patient’s response. If symptoms recur or don’t fully resolve within the protocol, continue careful monitoring and follow the protocol’s guidance for additional management rather than exceeding the total limit.
