Naloxone (commonly known by the brand name Narcan) is a life-saving medication designed to rapidly reverse an opioid overdose. Here is how it works and when a bystander should step in to use it.

How Naloxone Reverses an Opioid Overdose

To understand how naloxone works, you first have to understand how an overdose happens.

Opioids (such as heroin, fentanyl, oxycodone, hydrocodone, and morphine) work by binding to specific receptors in the brain and nervous system. While they relieve pain and produce a "high," they also depress the central nervous system. In an overdose, the opioids overwhelm the brain and cause the person’s breathing to slow down dangerously or stop entirely.

Naloxone acts as an "opioid antagonist." Here is how it works:

• 1.The "Bouncer" Effect: Naloxone has a stronger affinity (attraction) to the brain's opioid receptors than the opioids themselves. When administered, naloxone rushes to the receptors and physically knocks the opioid molecules off of them.
• 2.Blocking: Once it knocks the opioids off, naloxone binds to the receptors and blocks the opioids from getting back on.
• 3.Rapid Reversal: By clearing the receptors, naloxone stops the central nervous system depression. Within 2 to 5 minutes, the person's breathing will usually return to normal.

Important Note: Naloxone only works on opioids. It will not reverse overdoses caused by alcohol, benzodiazepines (like Xanax), or stimulants (like cocaine or meth)—however, it will not harm the person if they are given naloxone for a non-opioid overdose.

When Should a Bystander Use Naloxone?

A bystander should use naloxone immediately if they suspect someone is experiencing an opioid overdose. Because naloxone is harmless to someone who does not have opioids in their system, it is always better to administer it if you are unsure.

Signs of an Opioid Overdose:

Look for the following physical signs:

• •Breathing issues: Breathing is very slow, shallow, erratic, or has stopped completely.
• •Choking sounds: The person is making snoring, gurgling, or choking sounds (often called a "death rattle").
• •Unresponsiveness: The person is unconscious, limp, and cannot be woken up by shouting their name or rubbing your knuckles hard on the center of their chest (a "sternal rub").
• •Skin color changes: Lips and fingertips may turn blue, purple, or grayish (depending on skin tone). The skin may feel cold and clammy.
• •Pinpoint pupils: The black centers of the eyes are unusually small.

Step-by-Step: What a Bystander Should Do

If you see the signs above, take the following steps:

• 1.Call 911 immediately. Naloxone wears off in 30 to 90 minutes, but opioids can stay in the system much longer. The person could slip back into an overdose and needs professional medical care.
• 2.Administer Naloxone.
• •If you have nasal spray (Narcan): Lay the person on their back, tilt their head back, insert the tip of the nozzle into one nostril, and firmly press the plunger.
• •If you have injectable naloxone: Follow the package instructions (usually injected into the muscle of the thigh or upper arm).
• 3.Perform Rescue Breathing or CPR. If you are trained, provide rescue breaths or CPR while waiting for the naloxone to take effect, as the person’s brain is being starved of oxygen.
• 4.Wait and Assess. Wait 2 to 3 minutes. If the person does not wake up or start breathing normally, give a second dose of naloxone in the other nostril. (Because of powerful synthetic opioids like fentanyl, multiple doses are often required).
• 5.Stay with them. Once the person wakes up, they may be confused, agitated, or experiencing withdrawal symptoms. Keep them calm and stay with them until paramedics arrive. If you must leave them, or if they are breathing but unconscious, roll them onto their side (the recovery position) so they do not choke on their own vomit.

A Note on Bystander Protection

In the United States and many other countries, Good Samaritan Laws offer legal protection to bystanders who step in to help someone experiencing an overdose. These laws are designed to encourage people to call 911 and administer naloxone without fear of being arrested for drug possession.
