What is the most common route for naloxone administration in prehospital settings?

• A. Intramuscular injection
• B. Oral tablet
• C. Nasal spray
• D. Subcutaneous infusion

Answer: (C)

Intranasal administration is the most common route for naloxone in prehospital care because it delivers rapid systemic effects without the need for needles or IV access. The spray or nasal device lets responders quickly administer the antidote through the nasal mucosa, providing fast reversal of opioid effects while reducing the risks and delays associated with establishing IV access in the field. Oral tablets are not effective quickly due to poor and variable absorption and first-pass metabolism, and a subcutaneous infusion isn’t practical for rapid reversal in the field. While intramuscular injections are used in some situations, the nasal spray remains the preferred and most common method in many prehospital protocols due to its ease, safety, and speed.
