Key takeaway
After an overdose is reversed, an emergency team usually wants to keep you for observation, because breathing can slow again once naloxone wears off. Before you leave, you can ask about take-home naloxone, a referral to treatment, and whether medication for opioid use disorder is an option.

The scariest part of an overdose is often the quiet after it. Someone you love was gray and not breathing, and then they came back — and now you are standing in an emergency room being told they "have to stay a while," and you are wondering why they can't just come home. This is what the hours after survival are actually about, and what you can push for before anyone walks out the door.
Why they are not sending you straight home
When naloxone brings someone back, the danger has paused — not ended. The CDC's guidance for responding to a suspected overdose is direct on this point: call 911, and even if the person wakes up or seems to improve significantly, emergency medical care is still needed. It explains why: overdose symptoms may not fully improve, or they may quickly return after the first treatment.
The reason is timing. Naloxone is short-acting. In an overdose situation, it can restore normal breathing within two to three minutes, but the opioid that caused the overdose can outlast it. When the naloxone wears off, breathing can slow again. That is what the observation period is watching for. It is not bureaucracy. It is the window when a second slowdown would be caught.
What was actually happening to you
An opioid overdose is not a heart attack and it is not a choice. It is breathing shutting down because the opioid has overwhelmed the part of the brain that tells the lungs to work. Naloxone pushes the opioid off the receptor and the person starts breathing again. Some people wake up confused, angry, or sick to their stomach. That is the medicine and the withdrawal, not a character flaw, and it passes.
For family, one thing helps: stay calm and keep talking. The CDC's steps are to try to keep the person awake and breathing, lay them on their side to prevent choking, and stay until help arrives.
What should happen before you leave
There is a fairly consistent list of things good emergency departments do after a nonfatal overdose, drawn from public-health guidance for ED-based substance use response and state post-overdose policies. You may get some of these automatically, and you may have to ask for others:
- Take-home naloxone, or a prescription for it. Guidance for emergency departments says patients who use drugs should be offered or prescribed naloxone before discharge — not just the person who overdosed, but anyone in the household who might need it.
- A behavioral health or peer consultation during the visit.
- A referral to treatment, ideally a "warm handoff" with a real appointment, not just a phone number on a page.
- A conversation about medication for opioid use disorder — buprenorphine, methadone, or naltrexone — and whether to start it now or connect you to a clinic that will.
Why the medication conversation matters
This is the part that changes outcomes. Research on emergency-department buprenorphine shows that starting medication during or right after an emergency visit leads to more people staying in treatment, and that starting medication after a nonfatal overdose lowers the risk of dying. The NIDA guidance for emergency medicine describes how EDs can give a dose, send someone home with a short supply, and hand them off to a clinic that continues care.
You do not have to be certain you want treatment to have this conversation. You can say: "I'm not sure I want to stop, but tell me what medication would do." That is a complete sentence, and it is worth saying.
What a family member can ask for
You are not a bystander here. You can ask questions at discharge, and you can write down the answers:
- Is there naloxone going home with them, and can I be trained to use it?
- What is the follow-up plan — who, where, and how soon?
- Which clinic or prescriber am I supposed to call if they want treatment this week?
- What should I watch for in the next few days, and when do I call 911 instead of waiting?
If you are dealing with your own fear and anger, that is normal too. Our page on what happens after detox and the signs of overdose and naloxone may help you feel less powerless. If someone has overdosed and you are not sure they are fully out of danger, 911 first, always.
What you can do tonight
If you survived an overdose, the most useful thing tonight is not to be alone with it. Ask to speak to whoever handles substance use at the hospital — a social worker, a peer, a nurse — before you leave. Take the naloxone. Take the phone number. If the person you love overdosed and is being discharged, make sure more than one person in the house knows how to use naloxone and where it is kept.
When you are ready, call or text (800) 653-9376 and we will help you find a bed, a clinic, or a prescriber near you, whether that means medication, detox, or ongoing care. SAMHSA's National Helpline is free and confidential at 1-800-662-HELP (4357), 24 hours a day. For a mental-health crisis, call or text 988. If someone is not breathing, is turning blue, or cannot be woken, call 911 — and start naloxone if you have it.

Common Questions
Why can't I just go home once I wake up?
Because waking up is not the end of the event. The CDC's guidance for responding to a suspected overdose says that even if the person wakes up or seems much better after naloxone, emergency medical help is still necessary, because overdose symptoms may not fully improve or may quickly return after the first treatment.
What does naloxone actually do?
It is a fast-acting medicine that can reverse an opioid overdose and restore normal breathing, usually within two to three minutes. It works by blocking opioids at the receptor for a short time. When it wears off — often well before the opioid does — breathing can slow again, which is why observation matters.
What should the hospital offer me before I leave?
Guidance for emergency departments lists the same core items: take-home naloxone or a prescription for it, a behavioral health or peer consultation, a referral to treatment, and a conversation about medications for opioid use disorder such as buprenorphine. Many hospitals offer some but not all of these, so it is fair to ask.
Can I ask for medication for opioid use disorder in the ER?
Yes, and you can ask even if it is not offered to you first. Research shows that starting buprenorphine during or right after an emergency visit for opioid use disorder increases the number of people who stay in treatment, and starting medication after a nonfatal overdose reduces the risk of dying. Emergency departments can start it or connect you to a clinic that will.
A family member overdosed. What can I ask for at discharge?
Ask whether they are getting take-home naloxone, a written discharge plan with treatment contact information, and follow-up scheduled within days rather than weeks. Ask who to call if they relapse. You can also ask how to recognize another overdose and when to give naloxone, and whether you can be trained to use it.
