Naloxone (also known as Narcan®) is a medication that can temporarily reverse the effects of an opioid poisoning. An opioid poisoning (overdose) happens when someone has taken more opioids than their body can handle. It is a medical emergency because it can stop a person from breathing.

Learn how to administer Naloxone

The Good Samaritan Drug Overdose Act (Government of Canada) provides some legal protection to people who call for emergency help during an opioid poisoning.
