If you are a person who uses drugs or if you are around people who use drugs, please consider learning how to respond to an opioid overdose and carrying naloxone (intranasal brand name: Narcan). Naloxone is a medication designed to reverse an opioid overdose. Opioids slow down the activity of the central nervous system. This can cause slowed or stopped breathing which may lead to death. Naloxone displaces the opioids from the opioid receptors in the brain which allows the person who is experiencing an opioid overdose to begin breathing normally.
