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

How Naloxone Works

To understand how naloxone works, it helps to understand how opioids affect the body.

Opioids (such as fentanyl, heroin, oxycodone, and morphine) attach to specific receptors in the brain. When they attach, they block pain, but they also slow down the central nervous system. In the case of an overdose, they suppress the brain's drive to breathe. The person’s breathing slows down dangerously or stops entirely, leading to a lack of oxygen, brain damage, and death.

Naloxone acts as an "opioid antagonist."
Think of the opioid receptor as a lock, and the opioid as a key. Naloxone is a stronger key that fits into the exact same lock.

• 1.It knocks opioids off: When administered, naloxone travels to the brain and physically knocks the opioid molecules off the receptors.
• 2.It blocks opioids out: It then binds to those receptors, preventing the opioids from reattaching.
• 3.It restores breathing: Once the opioids are blocked, the brain's respiratory drive kicks back in, and the person begins to breathe normally again, usually within 2 to 3 minutes.

Note: Naloxone only works on opioids. It will not reverse overdoses caused by alcohol, cocaine, benzodiazepines, or other non-opioid drugs. However, if multiple drugs were taken and one was an opioid, it will still reverse the opioid's effects.

When a Bystander Should Use It

A bystander should use naloxone any time they suspect an opioid overdose.

Because an overdose cuts off oxygen to the brain, time is of the essence. You do not need to be a medical professional to administer naloxone.

Signs of an Opioid Overdose:

Administer naloxone if you cannot wake the person up (by shouting their name or rubbing your knuckles hard on the center of their chest) and they show any of the following signs:

• •Breathing issues: Breathing is very slow, shallow, erratic, or has stopped completely.
• •Strange sounds: Snoring, deep gurgling, or choking sounds (often called a "death rattle").
• •Color changes: Lips, gums, or fingernails turn blue, gray, or pale (depending on skin tone).
• •Skin: The skin feels cold and clammy.
• •Eyes: Pupils are "pinpoint" (the black center of the eye is very small).
• •Limp body: The person’s muscles are completely relaxed and limp.

The Golden Rule: If you are unsure whether the person is experiencing an overdose, give them naloxone anyway. Naloxone is incredibly safe. If the person is suffering from a heart attack, a diabetic emergency, or an alcohol overdose, naloxone will not harm them. It has no effect on someone who does not have opioids in their system.

What to Do if You Suspect an Overdose

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

• 1.Call 911: This is critical. Naloxone is a temporary fix. It wears off in 30 to 90 minutes, but opioids stay in the system much longer. The person can slip back into an overdose once the naloxone wears off.
• 2.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 into one nostril and press the plunger firmly.
• •Injectable: If you have the injectable version, follow the instructions provided with the kit (usually injected into the thigh or upper arm muscle).
• 3.Support Breathing: If you are trained in CPR, provide rescue breaths or chest compressions as needed while waiting for EMS.
• 4.Wait 2 to 3 Minutes: If the person does not wake up or start breathing normally within 2 to 3 minutes, give a second dose of naloxone in the other nostril (or a second injection). Overdoses involving potent synthetic opioids like fentanyl frequently require multiple doses.
• 5.Recovery Position: If the person wakes up and starts breathing, roll them onto their side (the recovery position). This prevents them from choking if they vomit. Stay with them until help arrives.

A Note on Legal Protection:
Most states and countries have "Good Samaritan" laws. These laws legally protect bystanders who administer naloxone and call 911 in good faith from being arrested for drug possession or being sued for trying to help.
