Naloxone is a life-saving medication that can stop an opioid overdose, including overdoses from heroin, fentanyl, and prescription opioids. Naloxone is safe and easy to use. It is most often given as a nasal spray.
Naloxone quickly stops an overdose by blocking the effects of opioids. It can restore normal breathing within 2 to 3 minutes in a person whose breath has slowed or stopped because of opioid overdose. More than one dose of naloxone may need to be given when stronger opioids like fentanyl are involved.
Even after administering naloxone to someone overdosing, they will need medical help.
