is narcan used for anything other than overdose
Naloxone Naloxone, sold under the brandname Narcan among others, is a medication used to block the effects of opioids, especially in overdose.[1] Naloxone may be combined within the same pill as an opioid to decrease the risk of misuse.[1] When given intravenously, naloxone works within two minutes, and when injected into a muscle, it works within five minutes;[1] it may also be sprayed into the nose.[3] The effects of naloxone last about half an hour to an hour.[4] Multiple doses may be required, as the duration of action of most opioids is greater than that of naloxone.[1]
