Narcan is a medicine that can save someone from a heroin, fentanyl, or prescription opioid medicine overdose. Narcan is the brand name for naloxone.
Narcan is small to carry and easy to use. It comes as a nasal spray or injection. You do not need medical training to use it.
Narcan prevents death by reversing the effects of heroin, fentanyl, and prescription opioid medicine on the brain and breathing. It works within a few minutes.
