Naloxone

Naloxone is a medication called an “opioid antagonist” used to counter the effects of opioid overdose, for example morphine and heroin overdose. Specifically, naloxone is used in opioid overdoses to counteract life-threatening depression of the central nervous system and respiratory system, allowing an overdose victim to breathe normally. Naloxone is a non-addictive, prescription medication. Naloxone only works if a person has opioids in their system; the medication has no effect if opioids are absent.
