Six steps that follow public-health overdose-response guidance. Read them now so they're ready when seconds count.
An opioid overdose can look like deep sleep that you can't wake someone from. Watch for: not responding to a shout or a firm rub on the breastbone; slow, shallow, or stopped breathing; gurgling, choking, or snoring sounds; blue or gray lips, fingertips, or skin; very small, pinpoint pupils; a limp body.
Tell the dispatcher exactly where you are and that someone is unresponsive and may not be breathing. Put the phone on speaker so your hands are free, and stay on the line — they will guide you. Calling for help is the single most important step.
For nasal spray: peel back the package, hold it with your thumb on the plunger and two fingers on the nozzle. Tilt the person's head back and support the neck. Gently insert the nozzle into one nostril until your fingers touch the bottom of their nose, then press the plunger firmly to release the full dose. Each device is one dose — do not test or prime it first.
After giving naloxone, help them breathe. If they are not breathing and you are trained, give rescue breaths (one breath every 5 seconds). If they are breathing on their own, place them in the recovery position — on their side — so they don't choke.
If there is no response after 2 to 3 minutes, give a second dose of naloxone in the other nostril, if you have one. It is safe to give more than one dose while you wait for help.
Naloxone wears off in about 30 to 90 minutes — often sooner than the opioids in the body, so the overdose can return. Stay with the person, keep them on their side, and let the paramedics take over. They need emergency care even if they wake up and feel fine.
A plain-language guide to how naloxone works, the forms it comes in, and why 911 still matters every time.
Naloxone (brand names include Narcan and Kloxxado) is an opioid antagonist — a medicine that can quickly reverse an opioid overdose by knocking opioids off the receptors in the brain and restoring normal breathing. It works on opioids such as heroin, fentanyl, and prescription pain pills.
The nasal spray is needle-free: one pre-filled device sprays a full dose into one nostril, which makes it the easiest form for the public to use. Injectable naloxone is also available and is typically given into a muscle, but it requires more training. Both deliver the same medicine.
If you are not certain an opioid is the cause, it is still safe to give naloxone. If the person has no opioids in their system, naloxone will not harm them — it has no effect when opioids aren't present. When in doubt, give it.
Naloxone only works for about 30 to 90 minutes. Because many opioids — especially fentanyl — last longer than that, a person can slip back into an overdose after it wears off. That is why calling 911 and staying with the person is essential, even after they respond.
Most states have Good Samaritan laws that provide some legal protection for people who call 911 in good faith to help during an overdose. The exact protections vary by state. Knowing your local law can help, but in an emergency, calling for help should always come first.
In most states naloxone is available at pharmacies without an individual prescription, and many health departments and community harm-reduction programs give it out for free along with training. Ask a pharmacist or your local health department how to get a kit before you ever need one.
