In brief: Really fast
If Narcan (naloxone) is given IV to overcome an opiate od, the effects are almost immediate.
If it is given im the response is slower.

In brief: Depends on how given
If given intravenously, it works literally in seconds (10-20 seconds to start working, works fully in couple minutes); if given intramuscularly (im) it takes 2-10 minutes to kick in.
If given in a nasal spray (which is being used in several communitites to help addicts and their friends treat od) it works in-between IV and im, starting in 1-2 minutes, and taking full effect by 5-10 minutes.
