Naloxone is better known today by the brand name Narcan. It stops overdoses to opioids like heroin, fentanyl, or oxycodone. Naloxone immediately revives a person who is overdosing. However, the large doses that paramedics must apply to those overdosing on the street often send the person into withdrawal, the symptoms of which are, among other things, shaking, shivering, and anxiety. Today, naloxone is widely available as a lifesaver for heroin and fentanyl overdoses.
