what is narcan used for?
Naloxone, also known as Narcan among other names, is a medication used to reverse the effects of opioids especially in overdose. Naloxone may be combined within the same pill as an opioid to decrease the risk of misuse. When given intravenously it works within two minutes and when injected into a muscle it works within five minutes. The medication may also be used in the nose. The effects of naloxone last about half an hour to an hour. Multiple doses may be required as the duration of action of most opioids is greater than that of naloxone.
