What is the preferred method to titrate naloxone in the field?

• A. Administer a fixed 2 mg IV bolus and reassess
• B. Administer small incremental doses and reassess respirations and mental status
• C. Use a continuous infusion at a fixed rate
• D. Administer a single intramuscular dose and stop

Answer: (B)

Titrating naloxone with small, incremental doses and reassessing is best because it lets you reverse opioid-induced respiratory depression without overshooting. Opioids vary in potency and duration, and naloxone’s duration can differ from the trapped opioid’s. By giving tiny doses and closely checking breathing, oxygenation, and mental status after each dose, you restore adequate ventilation while avoiding precipitating withdrawal or abrupt agitation. This approach also reduces the risk of re-narcotization if the opioid effect lasts longer than the naloxone. Fixed large doses or continuous infusions don’t adapt to the patient’s changing response in the field, making them less safe and effective.
