Naloxone onset occurs approximately how soon after administration?

Explanation:
Naloxone acts very quickly because it rapidly displaces opioids from mu receptors, so when given intravenously its effects are seen almost immediately. The typical IV onset is about one minute, making it the fastest route to reverse opioid-induced respiratory depression. The other time frames are too slow for IV administration; intramuscular or intranasal routes tend to take a couple of minutes. Therefore, about one minute is the best answer.
