What Happens During an Opioid Overdose?
When someone takes too much of an opioid-whether it’s prescription painkillers like oxycodone, heroin, or synthetic fentanyl-their breathing slows down until it stops. That’s because opioids bind to receptors in the brain that control breathing. Without oxygen, brain damage starts in under three minutes. Death can follow quickly if no help arrives.
Most people don’t realize they’re overdosing until it’s too late. Signs aren’t always obvious. The person might be unresponsive, their skin turns blue or gray, their lips are pale, and their breathing is shallow or irregular. Sometimes they’re just lying still, as if asleep. But this isn’t sleep. This is a medical emergency.
And here’s the hard truth: in 2022, over 107,000 people in the U.S. died from drug overdoses, and 80% of those involved synthetic opioids like fentanyl. These drugs are so strong that even a tiny amount can kill. That’s why knowing how to respond isn’t just helpful-it’s life-or-death.
How Naloxone Works to Reverse an Overdose
Naloxone is the only medication proven to reverse an opioid overdose. It doesn’t cure addiction. It doesn’t treat pain. But in those critical minutes after an overdose, it can bring someone back to life.
How? Naloxone kicks other opioids off the brain’s receptors. Think of it like a key that fits the same lock as heroin or fentanyl-but instead of turning the lock to shut down breathing, it pushes the other key out and resets the system. Within 3 to 5 minutes, breathing usually returns to normal.
It’s not magic. It doesn’t work on benzodiazepines, alcohol, or stimulants like cocaine. But if opioids are in the system, naloxone has a 95% success rate when given on time. Studies show that if it’s administered within two minutes of overdose, survival jumps to 95%. Delay it beyond five minutes, and that drops to 65%.
There are two main forms: nasal spray and injection. The nasal spray-like Narcan-is easier for most people to use. No needles. No training needed. Just spray one dose into each nostril. The injection works too, but it requires more skill and can be harder to use during panic.
Why One Dose Isn’t Always Enough
Here’s where people get caught off guard: naloxone wears off faster than many opioids. Its effects last 30 to 90 minutes. But fentanyl? It can stay in the body for hours.
That means someone might wake up after naloxone, feel fine, and walk away-only to slip back into overdose an hour later. This is called re-narcotization. It’s not rare. In 2022, the CDC found that 40% of fentanyl overdose reversals needed more than one dose of naloxone.
That’s why calling 911 is non-negotiable. Even if the person seems fine after the first spray, they need medical supervision for at least two hours. Emergency responders can monitor breathing, give more naloxone if needed, and handle complications like vomiting or seizures.
And yes, naloxone can cause withdrawal. If someone is dependent on opioids, they might suddenly feel sick-sweating, shaking, nauseous, angry. It’s terrifying, but it’s not dangerous. It’s better than dying.
How to Store Naloxone So It Works When You Need It
Naloxone is stable, but it’s not indestructible. Heat, light, and moisture can break it down. If you keep it in your glove compartment, your bathroom, or a hot car, it might not work when you need it most.
Best practice? Store it at room temperature (between 68°F and 77°F). Keep it in its original box. Avoid direct sunlight. Don’t freeze it. If you’re carrying it in your bag, use a small insulated pouch-those cheap ones from the pharmacy work fine.
Check the expiration date every few months. Most nasal sprays last two years. If the liquid looks cloudy or has particles, don’t use it. Replace it. Many community programs offer free replacements. Don’t wait until it’s expired to act.
Keep it where you can find it fast. Not locked in a cabinet. Not buried in a drawer. Near your keys, your wallet, or your phone. If you’re someone who uses opioids-or you know someone who does-keep a kit in your pocket. In your car. In your partner’s purse. In your child’s backpack if they’re a first responder or work in social services.
Who Should Have Naloxone? Everyone.
You don’t have to be a drug user to need naloxone. You don’t have to be a doctor. You don’t even have to be an adult.
Think about it: if your parent takes pain meds after surgery, your teenager gets prescribed oxycodone for a sports injury, your friend uses heroin, your neighbor takes methadone-any of them could overdose. And you might be the first person there.
In 2023, the FDA approved the first over-the-counter naloxone nasal spray. You can buy it at pharmacies without a prescription. It costs $130-$150 out of pocket, but many local health departments, needle exchanges, and nonprofits give it away for free. If you can’t afford it, ask. There’s no shame in asking for help to save a life.
And if you’re worried about encouraging drug use? The data says otherwise. Since community naloxone programs expanded, opioid overdose deaths have dropped by 14% in those areas. Giving people the tools to survive doesn’t enable addiction-it gives them a chance to get help.
What to Do If You Suspect an Overdose
- Call 911 immediately. Don’t wait. Don’t try to handle it alone.
- Check for breathing. If they’re not breathing or breathing is shallow, start rescue breathing if you know how.
- Administer naloxone. Use the nasal spray: tilt the head back, insert the nozzle into one nostril, press the plunger firmly. If no response after 2-3 minutes, give a second dose in the other nostril.
- Stay with them. Even if they wake up, keep them on their side in the recovery position. This stops them from choking if they vomit.
- Wait for EMS. Don’t leave them alone. They need professional care.
Reddit users who’ve reversed overdoses say the same thing: the hardest part isn’t giving the spray. It’s believing it’s real. You might think, ‘They’re just passed out.’ But if they’re unresponsive and not breathing normally, act. You won’t regret it.
Common Mistakes and How to Avoid Them
People make mistakes-not because they’re careless, but because they’re scared. Here’s what goes wrong, and how to fix it:
- Waiting too long to act. If you’re unsure, give naloxone anyway. It won’t hurt someone who hasn’t taken opioids.
- Not calling 911. Naloxone is a bridge to medical care, not a replacement. Always call.
- Using expired or damaged kits. Check the date. Look at the liquid. If it’s discolored, throw it out and get a new one.
- Not practicing. If you have a kit, open it once a month. Read the instructions. Practice the spray motion on a water bottle. Muscle memory saves lives.
- Assuming one dose is enough. Keep a second kit handy. Fentanyl is relentless.
Training takes 15 minutes. Most community programs offer it for free. You can watch a 10-minute video on the NIDA website. It’s not hard. It’s not scary. It’s just necessary.
What’s Next for Naloxone?
The science is evolving. In April 2024, the FDA approved an 8 mg nasal spray specifically for fentanyl overdoses. Clinical trials are underway for longer-lasting versions that could keep working for hours instead of minutes.
The Biden administration is spending $200 million to get naloxone into more homes, schools, and community centers. The goal? Two million kits distributed annually by 2026.
But naloxone alone won’t end the crisis. It’s a tool. The real solution includes better pain management, access to treatment, housing, and mental health care. Still, until those systems improve, naloxone is the best thing we have to stop people from dying before they get help.
It’s not about politics. It’s not about judgment. It’s about knowing that someone you love-or someone you don’t even know-could be minutes away from death. And you could be the one who stops it.

I've seen this play out in Delhi's underbelly - naloxone isn't just medicine, it's a lifeline tossed across class lines. My cousin, a street medic, carries two nasal sprays in his pocket like cigarettes. He says the hardest part isn't the spray - it's convincing people their friend isn't just 'sleeping it off.' In India, we don't talk about addiction, but we do bury people. This changes the script.

If you dont call 911 after giving naloxone you are literally killing that person even if you think theyre fine stop being a hero and start being responsible this is not a movie and your pride is not worth a human life

Let me ask you something - why is the government suddenly funding naloxone distribution? Coincidence that it’s right after the CDC started quietly reclassifying overdose deaths as ‘unintentional’ to make the opioid crisis look less like a policy failure? They’re not saving lives - they’re covering up the fact that fentanyl was pushed into the drug supply by cartel-backed pharmaceutical lobbying. Wake up.
Amy Ehinger
I keep a Narcan kit in my purse next to my lipstick and my phone charger. I got it free from the community center after my neighbor’s son overdosed in his car last winter. He woke up screaming and crying, all angry and sweating - I thought he was gonna punch me. But he hugged me five minutes later. We don’t talk about it. But I still carry it. You never know when you’ll be the one who shows up.

The notion that naloxone is a moral imperative is a dangerous fallacy rooted in the erosion of personal responsibility. To distribute reversal agents without addressing the underlying pathology of addiction is to enable chronic dependency under the guise of compassion. The state’s investment in naloxone is not humanitarian - it is institutionalized surrender. We are medicating the symptoms while allowing the disease to metastasize.
Frank Geurts
I would like to extend my deepest appreciation to the medical professionals, community volunteers, and public health advocates who have worked tirelessly to make naloxone accessible. The scientific rigor behind its development, the logistical coordination required for distribution, and the cultural stigma overcome in order to normalize its use - these are monumental achievements in public health. Thank you.

They say one dose isn't enough? That's because the fentanyl is laced with rat poison and the government knows it. They want you addicted so you'll keep buying. Naloxone is just a Band-Aid on a bullet wound. And the real villains? The same people who sold you the pills in the first place - doctors, pharma, the DEA. Wake up.
Amy Vickberg
I used to think this was someone else’s problem. Then my brother got prescribed oxycodone after his back surgery and ended up addicted. We found his naloxone kit in his sock drawer after he overdosed - expired. We got a new one the next day. He’s clean now. I carry two. I tell everyone I know to do the same. It’s not about judgment. It’s about showing up.
Ayush Pareek
In my village in Punjab, we don’t have naloxone. But we have neighbors. When someone goes quiet after taking painkillers, we sit with them. We talk. We splash water. We don’t wait for the ambulance - we walk. Sometimes we save them. Sometimes we don’t. But we never leave. You don’t need a spray to be human.
Nat Young
Let’s be real - how many of these ‘reversals’ are just people who got high, passed out, woke up, and now think they’re a hero? Naloxone doesn’t fix addiction. It just turns overdoses into a recurring event. You’re not saving lives - you’re extending the cycle. And the people who push this as a moral duty? They’re the same ones who won’t help with rehab.
Niki Van den Bossche
The real tragedy isn’t the overdose - it’s the fact that we’ve reduced human suffering to a pharmacological transaction. Naloxone is the pharmaceutical equivalent of a Spotify playlist for grief: convenient, emotionally sterile, and designed to make the bystander feel like they’ve done their part. But what of the soul that was broken before the breath stopped? We treat symptoms. We never tend to the wound.
Iona Jane
They say fentanyl is in everything now. But who put it there? The Chinese? The cartels? Or the same people who told us OxyContin was safe? This isn’t a crisis - it’s a controlled demolition. They want the poor addicted, the middle class dependent, and the rich rich. Naloxone is the glitter on the coffin. They don’t want you to die - they want you to need them.
