Which administration detail reduces the risk of nausea and vomiting when giving naloxone?

• A. Slow IV push over 2-3 minutes
• B. Rapid IV bolus
• C. Oral administration only
• D. Intramuscular injection only

Answer: (A)

Slowing the rate of naloxone administration minimizes abrupt reversal of opioid effects. When given as a rapid IV bolus, the drug’s concentration spikes quickly, which can abruptly displace opioids from receptors and trigger withdrawal-like autonomic responses, including nausea and vomiting. Delivering naloxone as a slow IV push over 2–3 minutes smooths the reversal, lowers the peak concentration, and reduces the likelihood of these GI side effects while still restoring respiration. Oral administration isn’t reliable for acute reversal because of poor and variable bioavailability, and intramuscular routes can still precipitate withdrawal and aren’t as controllable in timing as a carefully titrated IV approach.
