How to Use Narcan (Naloxone) to Reverse an Opioid Overdose

If you’re reading this, you might be worried about someone you love who uses opioids. You’re not alone. Opioid overdoses are a leading cause of accidental death, but they are preventable. Narcan (naloxone) is a safe, easy-to-use medication that can reverse an opioid overdose and save a life. This guide will walk you through exactly how to recognize an overdose and use naloxone step by step. Remember: in an emergency, always call 911 first.

What Is Narcan (Naloxone)?

Narcan is the brand name for naloxone, a medication that quickly reverses the effects of opioids. It works by blocking opioid receptors in the brain, restoring normal breathing in someone who has overdosed. Naloxone comes as a nasal spray (Narcan) or an injection. The nasal spray is the most common and easiest to use—no needles, no medical training required.

Naloxone is safe. If someone is not actually overdosing on opioids, giving naloxone will not harm them. It only works if opioids are present. It is now available over the counter at pharmacies without a prescription, and many community programs offer it for free. According to SAMHSA and NIDA, widespread access to naloxone is a key strategy in reducing overdose deaths.

How to Recognize an Opioid Overdose

Time is critical. Knowing the signs can mean the difference between life and death. Look for:

  • Unresponsive: The person doesn’t wake up when you shout their name or shake them gently.
  • Slow or stopped breathing: Breathing may be very slow, irregular, or absent. You might hear gasping or snoring sounds.
  • Blue or gray lips and fingertips: This signals a lack of oxygen.
  • Pinpoint pupils: The pupils become tiny, like pinpoints.
  • Gurgling or snoring sounds: This can happen when the airway is partially blocked.

If you see these signs, act immediately. Do not wait to see if they wake up.

Step-by-Step: How to Use Narcan Nasal Spray

Here’s what to do in an opioid overdose emergency. Follow these steps in order.

Step 1: Call 911 Immediately

Call 911 or have someone else call. Tell the dispatcher that you suspect an opioid overdose and that you are giving naloxone. Stay on the line and follow their instructions. Do not delay calling for help.

Step 2: Give Naloxone (Nasal Spray)

If you have Narcan nasal spray, use it right away. Here’s how:

  • Peel: Peel back the packaging to remove the spray.
  • Hold: Hold the spray with your thumb on the bottom and your fingers on the nozzle.
  • Insert: Insert the nozzle into either nostril until your fingers touch the person’s nose.
  • Press: Press the plunger firmly to release the dose.

If you have an injectable form, follow the instructions on the package. The nasal spray is preferred for ease of use.

Step 3: Give Rescue Breaths (If Trained)

If the person is not breathing, and you are trained in CPR, give rescue breaths. Tilt the head back, pinch the nose, and give two slow breaths. If you are not trained, chest compressions alone can help. Continue until the person breathes on their own or help arrives.

Step 4: Put Them in the Recovery Position

If the person is breathing but unconscious, place them on their side in the recovery position. This keeps the airway clear and prevents choking if they vomit. Bend their top leg and place their top arm under their head for support.

Step 5: Stay and Give Another Dose If Needed

Stay with the person until emergency help arrives. If there is no response after 2-3 minutes, give another dose of naloxone. Fentanyl and other powerful opioids may require multiple doses. Keep giving doses every 2-3 minutes until they wake up or help arrives.

You don’t have to figure this out alone.

What to Expect After Giving Naloxone

Naloxone works quickly, often within 2-5 minutes. The person may wake up confused, agitated, or in withdrawal. This is because the opioid is suddenly blocked. They might feel sick, have body aches, or be angry. Stay calm and reassure them. Remember, naloxone is temporary—it lasts only 30-90 minutes. The opioid can still be in their system, so they could overdose again. That’s why it’s crucial to get them to a hospital or call 911.

If the person is in severe withdrawal, it can sometimes be dangerous, especially if they have other health conditions. Medically supervised detox is the safe way to manage withdrawal. Never try to detox alone at home. If you or a loved one needs help, call 988 or go to the nearest ER.

Good Samaritan Laws: You’re Protected

Many states have Good Samaritan laws that protect people who call 911 for an overdose. These laws encourage people to seek help without fear of arrest for drug possession or use. When you call for help, you could save a life—and you are protected. Always call 911.

Where to Get Naloxone

Naloxone is available at most pharmacies without a prescription. You can also get it from community programs, harm reduction organizations, and some health departments. Many states offer free naloxone through standing orders. If you have a loved one who uses opioids, keep naloxone on hand. It’s a simple step that can save a life.

After the Overdose: A Chance to Get Help

Surviving an overdose is a critical moment. It’s a chance to get help. Treatment works, and recovery is possible. Encourage your loved one to seek professional help. There are many levels of care, from outpatient counseling to inpatient rehab. Medication-assisted treatment (MAT) can help with cravings and withdrawal. If there are mental health issues, dual diagnosis treatment addresses both. Confidential help is available 24/7. Specialists can verify insurance and find treatment nearby. Reach out today.
