What is naloxone, the “save shot”?

The drug naloxone is sometimes called a “save shot” or a “rescue shot” because of its ability to bring someone back from an overdose. Brand names for naloxone are Narcan and Evzio. It has long been used in hospitals and by emergency medical technicians, but there is now a movement to expand access to it and get it into the hands of first responders as well as drug users and their family members.
