How often can intranasal naloxone be repeated in emergency dosing?

• A. Every 1 minute
• B. Every 2-3 minutes
• C. Every 5 minutes
• D. Every 10 minutes

Answer: (B)

Naloxone is used to reverse opioid-induced respiratory depression, but its effect doesn’t last as long as many opioids, so you need to reassess quickly and re-dose at short intervals to prevent relapse of overdose symptoms. Intranasal naloxone often takes effect within a couple of minutes, but the duration can be shorter than the opioid’s effects, especially with potent or long-acting opioids. If there’s still insufficient reversal or symptoms redevelop, give another dose after about two to three minutes and continue this pattern until the patient is breathing adequately and stable, or until advanced care can take over. This approach balances rapid reversal with safety, since waiting too long (five or ten minutes) can allow respiratory depression to return, while too frequent dosing without reassessment isn’t necessary. After initial improvement, keep monitoring closely for several hours in case symptoms recur.
