Naloxone AKA Narcan is a medicine used in emergency situations where there is a suspicion that opioids have been taken and/or overdosed on.
This emergency medication reverses the devastating effects of an opioid overdose by blocking the opioid receptors in the brain. This is why it is called an opioid antagonist. It also prevents the person from overdosing again for a short while after it’s been initially administered.
