Naloxone (commonly known by brand names like Narcan or Kloxxado) is a life-saving medication that rapidly reverses an opioid overdose.

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

How Naloxone Reverses an Opioid Overdose

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

• 1.The Opioid Effect: Opioids (such as fentanyl, heroin, oxycodone, and morphine) attach to specific sites in the brain and nervous system called opioid receptors. Like a key fitting into a lock, opioids bind to these receptors to block pain and cause euphoria. However, in high doses, they severely depress the central nervous system, causing breathing to slow down dangerously or stop entirely. This lack of oxygen is what causes death in an overdose.
• 2.The Naloxone Reversal: Naloxone is an opioid antagonist. This means it is designed to bind to opioid receptors, but it does not activate them. Naloxone has a much stronger attraction (higher affinity) to these receptors than opioids do.
• 3.The "Knock-Off" Effect: When administered, naloxone rushes into the brain, physically knocks the opioids off the receptors, and binds to the receptors in their place. This instantly reverses the respiratory depression, allowing the person to start breathing normally again, usually within 2 to 3 minutes.

Note: Naloxone only reverses overdoses caused by opioids. It will not reverse overdoses caused by alcohol, benzodiazepines, or stimulants (like cocaine or meth), though it will not harm a person if they have taken these substances.

When Should a Bystander Use Naloxone?

You should administer naloxone any time you suspect someone is experiencing an opioid overdose.

Because naloxone is highly safe and has no effect on someone who does not have opioids in their system, it is always better to give it than to hesitate. If the person is suffering from a different medical emergency (like a heart attack or diabetic coma), giving them naloxone will not hurt them.

Signs of an Opioid Overdose

Look for the following signs. A person may exhibit one or several of these:

• •Unresponsiveness: They will not wake up or respond to a loud voice or a firm rub on the center of their chest (a sternal rub).
• •Breathing issues: Breathing is very slow, shallow, erratic, or has stopped completely.
• •Strange sounds: You may hear deep snoring, choking, or a gurgling sound (often called a "death rattle").
• •Skin color changes: In lighter-skinned people, the lips and fingertips may turn blue or purple. In darker-skinned people, the lips and fingertips may turn gray or ashen, and the skin may look pale or clammy.
• •Pinpoint pupils: The black circles in the center of the eyes are very small.

What to Do if You Suspect an Overdose (Step-by-Step)

If you see someone exhibiting these signs, take the following steps immediately:

• 1.Call 911: This is the most crucial step. Naloxone is temporary, and the person needs professional medical help.
• 2.Administer Naloxone:
• •Nasal Spray (most common for bystanders): Peel back the package, place the tip of the nozzle into one nostril until your fingers touch the bottom of the person’s nose, and press the plunger firmly to release the dose.
• •Injectable: Inject it into a large muscle, like the thigh or upper arm.
• 3.Support Breathing: If you are trained, perform rescue breathing or CPR while waiting for the naloxone to take effect.
• 4.Wait 2 to 3 Minutes: Stay with the person. If they do not wake up or start breathing normally after 2 to 3 minutes, give a second dose of naloxone (in the other nostril, if using the spray).
• 5.Roll Them on Their Side: If they start breathing on their own but remain unconscious, roll them onto their side (the recovery position) to prevent them from choking on their own vomit.
• 6.Stay Until Help Arrives: Naloxone wears off in about 30 to 90 minutes. However, opioids (especially synthetic ones like fentanyl) can stay in the body much longer. When the naloxone wears off, the person can slip back into an overdose without having taken any more drugs. Therefore, they must be monitored by medical professionals.

A Note on Legal Protection:
Many bystanders fear getting into legal trouble if they intervene in an overdose. The vast majority of U.S. states and many other countries have Good Samaritan Laws. These laws provide legal protection to bystanders who call 911 and administer aid in an overdose situation, protecting them from arrest or prosecution for minor drug offenses.
