Naloxone is a medicine used to treat opioid overdose. Opioids are strong pain medicines, and drugs such as heroin. Examples of opioids include codeine, morphine, oxycodone, methadone, fentanyl, tramadol and heroin. Opioids slow your breathing and affect your consciousness – if you take too much or overdose on opioids, your breathing may stop and you could die.

Naloxone works by reversing the effects of opioids. It can return normal breathing patterns to a person whose breathing has shallowed or stopped because of an opioid overdose. Naloxone can be given by injection or nasal spray and works very quickly, within 2–5 minutes.
