When should a second dose of Narcan be administered?

When should a second dose of Narcan be administered?

• A. Immediately after the first dose if the patient is conscious
• B. After 2-3 minutes, regardless of breathing
• C. After 2-3 minutes if breathing returns to normal
• D. After 2-3 minutes if breathing does not return to normal or breathing difficulty resumes, with a new device

Answer: (D)

Respiratory status after naloxone administration guides whether a second dose is needed. Naloxone reverses opioid-induced breathing depression quickly, but its effect can fade while the opioid’s effects persist, especially with powerful or long-acting agents. After the first dose, reassess breathing at about 2–3 minutes. If breathing has not returned to normal or if respiratory difficulty resumes, administer a second dose. Using a new device for the second dose helps ensure proper dosing and sterility. If breathing returns to normal, continue to monitor the person closely and be prepared for another dose if symptoms recur.
