Narcan, also known by its generic name naloxone, is a lifesaving medication that can reverse the effects of opioid overdose in mere minutes. Opioid overdoses often cause slowed or stopped breathing, which can quickly become fatal without intervention. As an opioid antagonist, Narcan works by binding to the same receptors in the brain that opioids attach to, effectively pushing those dangerous drugs off the receptors and reversing the effects of the overdose. It’s available in two forms: a nasal spray and an injection, with the nasal spray being the most user-friendly option for anyone witnessing an overdose. What makes Narcan especially valuable is that it works solely on opioids, so if you’re unsure whether someone is overdosing on opioids or another substance, it’s still safe to use.

If you are struggling with opioid addiction, let America’s Rehab Campuses offer you the help you need through our inpatient treatment programs. That provides a long-term solution for addiction and allows you to minimize the need for Narcan.

How Does Narcan Work?

Narcan works by attaching to opioid receptors. In doing so, it can reverse and block the effects of other opioids present. When a person suffers from an overdose of drugs such as heroin, fentanyl, hydrocodone, codeine, or oxycodone, their brain is operating at a very slow, low level. That means there are not enough signals going to the rest of the organs to function properly. The brain slows down its function, the heart slows down, and the lungs do as well. That means the body isn’t getting oxygen and will quickly be unable to function to maintain life.

When this occurs, a shot of Narcan can cause very fast results, often allowing for improvement within just a matter of a few minutes or less. By working to reverse the effects of opioids in the brain, the brain can return to normal function.

What Do You Feel?

A person overdosing is likely to pass out from a lack of oxygen to the brain. They are not likely to feel anything during this time and cannot communicate what is occurring. Should an emergency professional or someone else with Narcan use it, the administering of the drug does not cause immediate pain to the individual. However, once the drug reaches the brain, it may start to rouse again.

Narcan works to block opioid receptors like this for 30 to 90 minutes. However, most opioids remain in the body much longer than this. That means that even when a person “wakes up,” they are still at risk of overdosing again. That is why calling 911 is critical.

People who have a dependence on opioids may begin to experience withdrawal symptoms from opioids nearly immediately. This can include intense pain, a rapid heart rate, tremors, vomiting, sweating, and feelings of being ill. This is uncomfortable, but it is also very much expected.

Though rare, some people may have a negative reaction to Narcan that is more extreme. Some may be allergic to it. However, in most cases, the risks of taking Narcan are much better than allowing a person to overdose, as that can lead to a fatal outcome, brain damage, and numerous other health risks.

Myths About Narcan

Several misconceptions about Narcan can prevent people from using it when it’s needed most. Let’s clear up a few of these myths:

  • Myth 1: Narcan encourages people to keep using opioids.
    Fact: Research shows that Narcan does not promote drug use. It saves lives and provides a critical opportunity for individuals to seek treatment and begin their recovery journey.
  • Myth 2: Narcan is dangerous to use and could cause harm.
    Fact: Narcan does not affect people who have not overdosed on opioids, making it safe to use even if you’re unsure whether someone is experiencing an opioid overdose.
  • Myth 3: Narcan can only reverse heroin overdoses.
    Fact: Narcan works for all opioid overdoses, including those caused by prescription painkillers, fentanyl, and heroin.

Breaking down these myths can empower people to act when they see an overdose happening, knowing that Narcan is a safe, effective, and life-saving tool.

Access to Narcan and Legal Protections

The good news is that Narcan is becoming more accessible than ever before. Many states now allow pharmacists to dispense Narcan without a prescription, and community programs often provide it for free at public health events. In addition, first responders—including police officers, paramedics, and firefighters—are frequently equipped with Narcan as part of their emergency kits. But it’s not just for medical professionals. Family members, friends, and even those at risk of overdose can carry Narcan to prevent a life-threatening situation. One of the greatest barriers to helping others in overdose situations is the fear of legal repercussions. Thankfully, Good Samaritan laws exist to protect individuals who administer Narcan during an overdose, ensuring that you won’t face legal consequences if you’re trying to save someone’s life.

Have You Overdosed? What Should You Do Now?

For people who struggle with opioid addiction, it is not always possible to simply stop using. It may seem impossible to be able to no longer use a drug that you have become so dependent on. If you suffer from pain, cravings, and other withdrawal symptoms when you do not use these drugs, medical detox may be one of the most important steps in helping you to recover. America’s Rehab Campuses can help you with that type of care. You simply need to reach out to us to learn more about your treatment options.

Narcan can be a powerful and very important tool in your journey to health. Yet, it isn’t always available, and in some situations, a person may not ever really find themselves able to stop using opioids on their own, leading to a long-term need for this hard-to-obtain drug.

The Importance of Follow-up Care

While Narcan can save a life in the event of an opioid overdose, it’s important to understand that it is only a temporary solution. The effects of Narcan last for a limited time (30-90 minutes), while the opioids in the person’s system may last much longer. After administering Narcan, always call 911 and make sure the person gets immediate medical attention. Narcan reverses the overdose, but it doesn’t treat the underlying addiction. That’s why it’s crucial to connect those who’ve been revived with addiction treatment services. Detox, counseling, and rehabilitation programs are vital for long-term recovery and preventing future overdose incidents. Narcan is just the first step toward healing and recovery, but it opens the door for the person to get the help they need.
