If you think someone is overdosing right now: Call 911 immediately, give naloxone (Narcan) if you have it, and stay with them. Don't wait to be sure — it's safe to give naloxone even if you're wrong. Every second counts.

A fentanyl overdose can happen fast — sometimes within minutes. Knowing the signs and knowing exactly what to do is the difference between a tragedy and a life saved. The good news: an opioid overdose can often be reversed if someone acts quickly with naloxone. This guide walks you through how to recognize a fentanyl overdose, the step-by-step response, and how to be ready before an emergency ever happens.

I've been in rooms where someone's life hung on whether the people nearby knew what to do. They don't teach this in school, so let's make it simple and clear — because anyone can save a life with the right knowledge and a dose of naloxone.

Fentanyl is involved in the large majority of opioid overdose deaths in Ohio — about 95% of opioid overdose deaths in 2023, per the Ohio Department of Health. It's also reversible with naloxone, which is free across Ohio. Knowing the signs saves lives.

What are the signs of a fentanyl overdose?

Fentanyl is an opioid, so an overdose looks like an opioid overdose: the body's drive to breathe slows down and can stop. Watch for these signs — you may see several at once:

SignWhat it looks like
BreathingSlow, shallow, irregular, or completely stopped
ResponsivenessWon't wake up; no response to shouting or a firm sternum rub
PupilsPinpoint — very small, "pinned"
Skin & lipsBlue, gray, or ashen lips, fingertips, or face
BodyLimp; may be cold or clammy
SoundsGurgling, choking, or a deep snore-like "death rattle"

That gurgling or snoring sound is a critical warning — it is not normal sleep. If you can't wake someone and they're making those sounds, treat it as an overdose.

What to do during a fentanyl overdose, step by step

If you suspect an overdose, act immediately. Don't waste time being certain — it is safe to respond even if it turns out not to be an overdose.

  1. Call 911. Say where you are and that someone isn't breathing or is unresponsive. Professional help on the way is essential — naloxone can wear off before the fentanyl does.
  2. Give naloxone (Narcan). Spray one dose into one nostril. If there's no response after 2–3 minutes, give another dose. A fentanyl overdose often needs more than one dose.
  3. Support their breathing. If trained, give rescue breaths (one every 5 seconds) or CPR. Restoring oxygen is what prevents brain injury and death.
  4. Keep giving naloxone every 2–3 minutes until the person responds or help arrives.
  5. Stay and use the recovery position. If you must step away or they vomit, roll them onto their side to keep their airway clear. Don't leave them alone — they can re-overdose as naloxone fades.
Ohio's Good Samaritan law (ORC 2925.11) provides limited legal protection from minor drug-possession charges for people who seek emergency help during an overdose — for themselves or someone else. The law exists so fear of arrest never stops someone from calling 911. Make the call.

About naloxone (Narcan)

Naloxone is a safe, easy-to-use medication that reverses an opioid overdose by knocking opioids off the brain's receptors and restoring breathing. A few things everyone should know:

  • It only works on opioids. It won't harm someone who isn't overdosing on opioids, so it's safe to give if you're unsure.
  • Fentanyl may need multiple doses because of its potency.
  • It wears off in 30–90 minutes — sooner than fentanyl can last — so the person can slip back into overdose. That's why 911 and staying with them matter.
  • It can cause sudden withdrawal, which is uncomfortable but not dangerous. The person may wake up confused or sick; keep them calm and don't let them use again.
  • It's free in Ohio. See how to get it in our Ohio overdose prevention resources.

Myth: can you overdose from touching fentanyl?

No. Despite alarming stories, medical and toxicology experts are clear that you cannot overdose from brief skin contact with fentanyl — it isn't absorbed through intact skin in amounts that would cause harm from incidental touch. This myth is dangerous because it makes bystanders hesitate to help. If someone is overdosing, give care and give naloxone. (Basic precautions like avoiding hand-to-mouth contact and washing your hands afterward are still sensible.)

How to be ready before an emergency

The best time to prepare is now, not during a crisis:

  • Carry naloxone if you or a loved one is at risk — it's free in Ohio with no prescription.
  • Use fentanyl test strips if someone is going to use anyway; fentanyl is in much of the supply. Both are covered in our resources guide.
  • Never use alone, and make sure others know the signs and where the naloxone is.
  • Know that recovery is possible. Reversing an overdose buys a second chance — the next step is getting into care.

Frequently asked questions

What are the signs of a fentanyl overdose?

Slow, shallow, or stopped breathing; a person who won't wake up; pinpoint pupils; blue or grayish lips and fingertips; a limp body; and gurgling, choking, or snore-like sounds. If you see these, treat it as an overdose — call 911 and give naloxone.

What should you do if someone is overdosing on fentanyl?

Call 911, give naloxone (repeat after 2–3 minutes if no response), give rescue breaths or CPR if trained, and stay with the person — place them on their side if you must step away. Keep giving naloxone until they respond or help arrives. Ohio's Good Samaritan law protects those who call for help.

How many doses of Narcan does a fentanyl overdose need?

Often more than one. Give a dose, wait 2–3 minutes, and repeat if there's no response — until the person breathes normally or responders arrive. Naloxone wears off before fentanyl does, so the person can re-overdose, which is why you call 911 and stay.

Can you survive a fentanyl overdose?

Yes — many people survive when someone recognizes the signs quickly, calls 911, and gives naloxone, which can rapidly reverse an opioid overdose. Speed, naloxone, and staying with the person until help arrives are the keys.

Can you overdose from touching fentanyl?

No. Experts are clear that you can't overdose from brief skin contact — fentanyl isn't absorbed through intact skin in harmful amounts from incidental touch. Don't let this myth make you hesitate to help someone who's overdosing. Provide care and give naloxone.
