There's this mentality though that therapy has no down side.
Let's go down this rabbit hole for a minute, and discuss this topic... What's the downside? What is the negative outcome to giving narcan to a person who doesn't need it?
Let's say I narcan every unconscious patient I come across... Other than reacting with any prescribed opioids they are on (which isn't the goal, but a valid concern), will they get worse? I agree, they won't get better (as it isn't addressing the reason they are unconscious, so it's not helping), and if they are not breathing before you gave narcan, then you should be ventilating before and after, but it's not going to cause a negative reaction to the patient.
If I give narcan to every cardiac arrest, right after I give the epi, what's the downside? will the patient get deader?
if I give narcan to every person I meet, if they aren't using opioids, will they suffer any negative consequences?
To be perfectly clear, I'm not suggesting that I would, or that anyone should, but just discussing the idea that narcan has no downsides.
If I give too much narcan too fast, it can cause the patient to experience projective vomiting, and in rare cases, flash pulmonary edema (as per
PubMed), but that's only if a person has opioids in their system.
Also, giving narcan is not a one and done treatment, so if people think it is, that's another issue. ventilate before and afterwards, until the victim is spontaneously breathing on their own. maybe companies should give one a face mask with one way valve with every narcan they distribute?
