Narcan®, also known by its generic name naloxone, is a medication that can reverse an opioid overdose and help bring someone back when their breathing has slowed or stopped. It is one of the most powerful tools we have in the fight against the opioid crisis. That is why it is often carried by first responders, healthcare workers, and families who want to be ready just in case.

But even as Narcan becomes more widely available, there is still a lot of confusion about what it does. Some believe it can treat any kind of overdose. Others worry it might cause harm if given to someone who is not using opioids. These kinds of misunderstandings can lead to hesitation in moments when every second matters. Knowing the truth about Narcan, including both its purpose and its limits, could save a life. The sections below will explain what Narcan can and cannot do and why it is still an essential tool in emergencies.

What Narcan Does Do: Understanding Its Capabilities

If you've ever seen someone struggle with an opioid overdose or worried about the possibility, you know how crucial it is to act fast. Whether you're a family member, a first responder, or just want to be ready, Narcan can make all the difference. Of course, Narcan is not a cure for addiction, but it offers a second chance. When administered quickly and adequately, it can reverse the effects of an opioid overdose and help someone breathe again, giving them the time they need to get the medical care they urgently need.

Here’s a simple breakdown of what Narcan is made to do:

  1. Reverse opioid overdose: If someone you love stops breathing because of opioids, Narcan can help bring them back.
  2. Restore breathing: Within minutes, Narcan can help a person start breathing again, even before EMS arrives.
  3. Work quickly and effectively: Time is critical in an overdose. Narcan usually begins to work within 2 to 3 minutes.
  4. Be used by anyone, not just medical professionals: Whether you're a parent, friend, or bystander, Narcan is designed for safe, easy use.
  5. Trigger withdrawal in opioid users: Narcan may cause discomfort, but it can save a life. Withdrawal is temporary, and death is not.
  6. Be safe to give even if you're unsure: If you’re not sure whether someone used opioids, it’s still safe to use Narcan. It won’t harm them.

Breakdown of What Narcan Can Do

Understanding what Narcan can do is the first step in being ready to help. The following sections will clarify some common myths about Narcan, including what it cannot do.

What Narcan Does Not Do: Debunking Myths

Narcan is a powerful tool for reversing opioid overdoses, but it's essential to understand what it cannot do. While it saves lives in critical moments, it does not address all medical situations, and there are limits to its effectiveness. This section will clarify the misconceptions and help you understand the boundaries of Narcan’s capabilities.

Here are some things Narcan cannot do:

  1. Does not work on non-opioid overdoses: Narcan only reverses opioid overdoses. It does not affect overdoses caused by alcohol, cannabis, or other substances.
  2. Does not treat addiction: Narcan is a temporary solution to an overdose. While it can reverse the immediate effects, it does not address the underlying opioid use disorder.
  3. Cannot be used recreationally: It won’t give you a high or cause any kind of euphoric effects, and it has no abuse potential.

In the following sections, we address some of the most common myths and questions about Narcan, clearing up confusion and providing the necessary facts.

Does Narcan Work on Alcohol?

No, Narcan does not reverse alcohol overdose. Narcan is specifically designed to reverse the effects of opioids, such as heroin, fentanyl, oxycodone, and morphine. It works by blocking opioid receptors in the brain. Alcohol, on the other hand, is a depressant that affects the brain differently. Because of this, Narcan does not affect alcohol poisoning or intoxication. If someone is experiencing alcohol poisoning, signs might include vomiting, slow or irregular breathing, confusion, or unconsciousness. The proper response is to call 911 immediately. While waiting for emergency help, keep the person awake and sitting up if possible. If they’re unconscious, place them on their side to prevent choking. Emergency treatment may include oxygen, intravenous fluids, and close monitoring in a hospital setting. If you’re unsure whether a person is overdosing on alcohol or opioids, it’s still safe to give Narcan. It won’t harm someone who doesn’t have opioids in their system, but it also won’t help if opioids aren’t the cause.

Can Narcan Get You High?

No, Narcan does not get you high. It is not a recreational drug. Narcan (naloxone) works by blocking opioid receptors in the brain. Thus, it does not create a sense of euphoria or pleasure. Instead, it removes opioids from those receptors, stopping their effects. People who are high on opioids may suddenly feel withdrawal symptoms after receiving Narcan. This feeling is not a high, but rather an abrupt reversal of the opioid's effects.

Here are some key points worth remembering about Narcan:

  1. Narcan is non-addictive: Narcan (naloxone) does not create a physical dependence, meaning it won’t lead to addiction in the person who receives it. It works purely to reverse the effects of an opioid overdose, and it doesn't cause any cravings or lasting changes in the brain's reward system.
  2. Narcan cannot be used to get high: Unlike opioids, Narcan doesn't produce any euphoric or pleasurable effects. Its sole function is to block the effects of opioids at the receptor level, which can lead to withdrawal symptoms for someone dependent on opioids but never a high or intoxication.
  3. Narcan has no street value or abuse potential: Since Narcan is not addictive and doesn't alter mood in a way that would encourage misuse, it has no appeal as a recreational drug. It’s only valuable in an emergency when someone is overdosing on opioids.
  4. Narcan’s only purpose is to reverse an opioid overdose and restore breathing: Narcan is specifically designed to reverse the life-threatening effects of opioid overdose. It quickly restores breathing and consciousness, giving the person a second chance until professional medical help arrives.

Narcan is a life-saving medication. It is a safety tool that helps someone survive an overdose. It is not something that people use to get intoxicated.

How Long Does Narcan Last?

The effects of Narcan typically last between 30 and 90 minutes. This timeframe is enough to reverse an opioid overdose and help someone start breathing again. However, some opioids stay in the body much longer than Narcan does, such as potent synthetic opioids like fentanyl. Because of this, the person may relapse into an overdose after the Narcan wears off.

Here’s what you need to know about Narcan:

  1. Narcan works quickly, usually within 2 to 3 minutes, but its effects are temporary.
  2. Always call 911 immediately after giving Narcan, even if the person seems to recover.
  3. Stay with the person and monitor them closely for signs that their symptoms may return.
  4. A second dose of Narcan may be necessary if the person stops breathing again.

Narcan can save a life, but emergency care is still essential. It gives people a second chance, but they still need medical help.

What Does Narcan Do to a Sober Person?

If Narcan is given to someone who is not using opioids, it will not cause harm. Narcan only works on opioids. If there are no opioids in the body, it simply has nothing to block.

Some people may feel mild side effects, such as:

  • Headache
  • Nausea
  • Fast heartbeat
  • Nervousness or restlessness

These symptoms are usually minor and short-lived. 

Why it's safe to use even if you are unsure:

  • Narcan will not cause a high
  • It will not hurt someone sober
  • It is better to use it than to risk waiting too long

In any suspected overdose, the safest choice is to give Narcan and call for help. Even if you are not sure what drugs were taken, it is always better to act quickly.

Conclusion: Knowing When and How to Use Narcan

Narcan is a life-saving medication that can reverse the effects of an opioid overdose and help restore breathing in a critical moment. In a nutshell, here’s what it can and cannot do:

  • Narcan only works on opioids such as fentanyl, heroin, and prescription pain relievers.
  • It does not help in cases of alcohol poisoning, cannabis use, or other non-opioid drugs.
  • It is not used to get high and has no value as a recreational substance.

When a life is at risk, having Narcan available and knowing how to use it can make all the difference. If you or someone you love is at risk for opioid overdose, having Narcan nearby can make all the difference. Speak to an addiction specialist at North Palm Beach Recovery today.
