 You want to spray into one nostril, and then you want to stay with the victim until train help arrives. I would recommend you turn them on their side at that point. But the key point I'd really like to make is that naloxone, it cannot hurt anyone. So if you've misjudged and say it's not an opioid overdose, it's okay because it will just have no effect whatsoever. But if their opioids are present, it's going to reverse things.
