Naloxone & Opioid Poisoning

Naloxone, also known by the brand name Narcan, is a medication that can reverse the effects of an opioid poisoning/overdose. Naloxone binds more effectively to the opioid receptors in the brain, temporarily removing the opioid and their harmful effects. This, in turn, reverses the respiratory depression that can lead to a fatal opioid overdose.

Once administered, naloxone will start to work in approximately 1-5 minutes. Naloxone stays active in the body for 60-90 minutes. Since naloxone only temporarily removes opioids from the opioid receptors, opioids will return back to the receptors and overdose symptoms can return.

It is important to always call 911 before administering naloxone outside of a medical or hospital setting.
