Naloxone (commonly known by the brand names Narcan® or Kloxxado®) is a life-saving medication designed to rapidly reverse an opioid overdose.

Here is a clear breakdown of how it works and when a bystander should use it.

Part 1: How Naloxone Reverses an Overdose

To understand how naloxone works, it helps to understand how an opioid overdose happens in the first place.

• 1.The Overdose: Opioids (such as fentanyl, heroin, oxycodone, and morphine) travel through the bloodstream and attach to specific targets in the brain called opioid receptors. When too many opioids attach to these receptors, they severely depress the central nervous system, causing the person's breathing to slow down dangerously or stop entirely. This lack of oxygen is what causes death in an overdose.
• 2.The Reversal: Naloxone is an opioid antagonist. This means it has a stronger attraction (higher affinity) to the brain's opioid receptors than the opioids themselves do.
• 3.The "Knock-Off" Effect: When administered, naloxone rushes to the brain, knocks the opioids off the receptors, and binds to those receptors itself.
• 4.Restoring Breath: Because naloxone does not activate the receptors the way opioids do, the central nervous system wakes up, and the person's normal breathing is restored—usually within 2 to 3 minutes.

Note: Naloxone is temporary. It wears off in 30 to 90 minutes. Because many opioids (especially fentanyl) stay in the body longer than naloxone, a person can slip back into an overdose once the naloxone wears off. This is why emergency medical help is always required.

Part 2: When a Bystander Should Use It

The golden rule of naloxone is: When in doubt, use it. Naloxone is incredibly safe. It has no effect on someone who does not have opioids in their system. If you suspect an overdose but aren't sure if it was caused by opioids, alcohol, or other drugs, give naloxone anyway. You cannot hurt them by giving it, but you could save their life.

Signs of an Opioid Overdose

You should administer naloxone if a person is exhibiting any of the following signs:

• •Unresponsiveness: They will not wake up when you shout their name or vigorously rub your knuckles up and down the center of their chest (a "sternal rub").
• •Breathing issues: Their breathing is very slow, shallow, erratic, or has stopped entirely.
• •Abnormal sounds: They are making choking, gurgling, or loud snoring noises (often called the "death rattle").
• •Skin color changes: Their skin may look pale or clammy. On lighter skin, the lips or fingertips may turn blue or purple. On darker skin, the lips or fingertips may look grayish or ashen.
• •Pinpoint pupils: The black centers of their eyes are very small, like the head of a pin.

What a Bystander Should Do (Step-by-Step)

If you witness the signs above, take these steps immediately:

• 1.Check for a response: Shout their name and do a hard sternal rub.
• 2.Call 911: Do this immediately. Tell the dispatcher the person is unresponsive and struggling to breathe.
• 3.Administer Naloxone:
• •Nasal Spray (Narcan): Peel back the package, hold the device with your thumb on the plunger and two fingers on the nozzle. Insert the nozzle fully into one nostril and firmly press the plunger.
• •Injectable: Inject the vial of liquid into the muscle of their upper thigh or upper arm.
• 4.Support their breathing: If you know how to do rescue breathing or CPR, begin doing so.
• 5.Wait and observe (2-3 minutes): If the person does not wake up or breathe normally after 2 to 3 minutes, give a second dose of naloxone (in the other nostril, if using the spray). You can continue giving doses every 2-3 minutes until help arrives.
• 6.Put them in the Recovery Position: If the person begins breathing on their own but is still unconscious, or if you have to leave them for a moment to get help, roll them onto their side. Bend their top knee and support their head with their bottom arm. This prevents them from choking on their vomit.
• 7.Stay with them: Stay until emergency medical services arrive. The person may wake up confused, agitated, or experiencing opioid withdrawal symptoms. Reassure them and keep them calm.

If you are interested in carrying naloxone, you can often get it at your local pharmacy without a prescription, or through local community harm-reduction organizations. Familiarize yourself with the specific instructions on the packaging of the naloxone you carry.
