Naloxone, also known by Narcan and other brand names such as Kloxxado, is the only antidote to opioid poisoning or an opioid overdose. It has no negative side effects.
Naloxone quickly reverses 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 even stopped, as a result of opioid overdose. More than one dose of naloxone may be required when stronger opioids like fentanyl are involved.
Naloxone won’t harm someone if they’re overdosing on drugs other than opioids, so it’s always best to use it if you think someone is overdosin.
If you give someone naloxone, stay with them until emergency help arrives or for at least four hours to make sure their breathing returns to normal.
You will not be held liable for wrongdoing if you administer naloxone to a person you suspect is experiencing an overdose.
In addition to a wealth of information about opioids and overdoses the websites for both Narcan and Kloxxado feature instructions for properly administering naloxone. The effects are temporary, and it may take 5 or more minutes for the medication to reverse an overdose.
However, if a person is still unresponsive or suffering warning signs, you can administer a second dose of the medication within 2-3 minutes if emergency responders have yet to arrive.
