If someone is having a seizure, can’t breathe, is hallucinating or has chest pain during withdrawal or after using, call 911 and go to the ER. If the situation is stable but you know withdrawal is coming, a medically supervised detox is the planned, safer setting. It is built to manage withdrawal and then move you straight into treatment. The ER stabilizes emergencies. Detox manages withdrawal on purpose, with a plan for what comes next.
This guide explains how to tell the two situations apart, what each setting does, and how families can act without risking a home detox.
TL;DR
- Emergency signs mean 911, not a detox bed. Seizures, trouble breathing, a heart rate over 120 that won’t slow, chest pain, repeated vomiting or vomiting blood, and hallucinations are emergencies.
- The ER treats the crisis. Many emergency rooms are not set up to treat addiction and may simply refer you onward once you are stable.
- Planned medical detox manages withdrawal itself, with clinicians monitoring you around the clock and treatment starting at the same time.
- Detox alone is not recovery. Stopping use without follow-up care raises relapse and overdose risk, so line up the next level of care before you leave either setting.
- Never detox alone from heavy alcohol use. Severe alcohol withdrawal can be fatal.

The short answer: emergency or planned?
The choice usually comes down to one question: is this happening right now and getting worse, or can it be arranged in the next hours or days?
| Situation | Better fit |
|---|---|
| Seizure, loss of consciousness, severe trouble breathing, chest pain | ER via 911 |
| Suspected overdose or alcohol poisoning | ER via 911 |
| Hallucinations, extreme agitation or violence, thoughts of suicide or harming others | ER via 911 or 988 |
| Heavy daily drinking or opioid use, no emergency symptoms yet, ready to stop | Planned medical detox |
| Mild to moderate withdrawal, stable vital signs, wants ongoing treatment | Medical detox, then residential care |
| Stable after ER visit, still using or at risk of relapse | Medical detox or residential treatment as the next step |
The two are not rivals. For many people the ER is the door in a crisis, and a treatment program is where the actual recovery work happens. The goal is to avoid the crisis in the first place, and to avoid leaving the ER with no plan.
When to go to the ER
Some signs are not negotiable. Kaiser Permanente’s care instructions say to call 911 if you can’t stop yourself from hurting yourself or someone else, vomit repeatedly or vomit blood, have trouble breathing or breathe very fast, have a heart rate over 120 that won’t slow down, have chest pain, have a seizure, or hallucinate.
If you are caring for someone who is detoxing, the same guidance says to call if they pass out, repeatedly hallucinate, become very agitated or violent, or have a seizure.
The Veterans Affairs guidance on urgent help for unhealthy alcohol use adds a few more triggers:
- Symptoms of alcohol poisoning, such as vomiting, coughing up blood, gasping for breath, passing out or seizures
- A history of heavy drinking with severe withdrawal symptoms in someone who refuses treatment
- Alcohol withdrawal seizures
- Delirium tremens
- Thoughts of suicide or of harming others
For a suspected drug overdose or withdrawal emergency, MedlinePlus says to call 911 or your local emergency number right away, check the person’s airway, breathing and pulse, begin CPR if needed, and give naloxone if it is available and an opioid overdose is suspected.
If the emergency is a mental health crisis, you can also call or text 988, the Suicide & Crisis Lifeline. Do not wait to see whether symptoms pass.
What the ER can do, and what it usually doesn’t
An emergency department is excellent at keeping you alive. According to MedlinePlus, providers may take a history and do a physical exam, then use tools such as activated charcoal, airway and breathing support, blood and urine tests, CT scans, chest x-rays, ECG, IV fluids and medicines that reverse drug effects. A mental health and social work evaluation may also happen. In serious cases you may be admitted to the hospital.
For alcohol withdrawal seizures, a 2020 review of withdrawal management in the emergency department describes immediate treatment with benzodiazepines, given by IV or, when IV access isn’t secured, by injection into the muscle, until the seizure stops. That is the kind of rapid intervention you cannot get at home.
What the ER is typically not designed for is the long arc of recovery. WebMD notes that many emergency rooms are not prepared to treat addiction and may refer you to a local treatment center if you are not having a medical emergency. In practice, that can mean a short stay, stabilization, and discharge.
The same 2020 review explains that once a patient is stable, the ER clinician must decide the next level of care using ASAM criteria, weighing medical needs, psychiatric needs, readiness for change and relapse risk. Options range from an extended ED stay to ICU admission. Some hospitals are building bridges here. The California Health Care Foundation describes “Bridge Navigators”, certified alcohol and drug counselors who meet patients face to face in the ED after stabilization, help them get into addiction treatment, and follow up by phone after discharge. Whether your local ER has anything like that varies, so ask before you are discharged.
The gap after discharge
The ASAM Implementation Guide for hospital and emergency department care states that withdrawal management alone can raise a patient’s risk of substance-related illness and death because tolerance is lost. It says treatment of the underlying substance use disorder should start at the same time. For opioid withdrawal, it says the standard of care includes both managing symptoms and offering medication for opioid use disorder.
That is the practical lesson for families: leaving an ER without a treatment plan is the riskiest moment, not the safest one.
What medical detox is, and how it differs
Medical detox is a planned stay where clinicians manage withdrawal and monitor you continuously. The clinical term has changed. In the third edition of the ASAM Criteria, “detoxification” was replaced with “withdrawal management,” which Pennsylvania’s state guidance lists as five levels:
- Level 1-WM: ambulatory, without extended monitoring
- Level 2-WM: ambulatory, with extended on-site monitoring
- Level 3.2-WM: clinically managed residential
- Level 3.7-WM: medically monitored inpatient
- Level 4-WM: medically managed intensive inpatient
The 2020 review summarizes the same ladder by severity: mild withdrawal can be managed in an ambulatory setting, moderate withdrawal calls for on-site monitoring or 24-hour residential support, and severe or unstable withdrawal needs inpatient care, up to the ICU depending on other health conditions.
The ER sits at the top of that ladder for emergencies. A dedicated detox program sits in the middle for people who need medical supervision but are not in crisis. The right level depends on the substance, how much and how long you have used, past withdrawal history, and other medical or psychiatric conditions.
What to expect during a structured detox
Exact details differ by program and substance, but the shape is consistent:
- Assessment. A clinician reviews your history, the substances you use, other medications and any mental health diagnoses.
- Monitoring. Staff track vital signs and symptoms through the hardest hours, and adjust care as withdrawal changes.
- Medication when appropriate. Depending on the substance, medicines may ease symptoms or reduce risk. Our guides explain how this works for alcohol detox medications and opioid withdrawal medications.
- Treatment alongside withdrawal. The Pennsylvania guidance, citing the ASAM Criteria, says the onset of withdrawal can be an unusual opportunity to engage someone in sustained recovery, and that counseling and therapy can begin at the same time as withdrawal management rather than after it.
- A transition plan. Before detox ends, the next level of care should already be arranged.
How long it lasts depends on the substance, the amount and duration of use, and your health. Alcohol, opioids, benzodiazepines and stimulants all follow different timelines. For a closer look, see our alcohol detox timeline and the opioid detox process.
Which substances call for medical supervision
Not every substance carries the same physical risk when you stop, but some are dangerous enough that stopping cold turkey is never the plan. Heavy alcohol use is the clearest case. Kaiser Permanente’s instructions say people who drink large amounts of alcohol should not try to detox at home, because a person can die of severe alcohol withdrawal.
Partnership to End Addiction explains that severe alcohol withdrawal, scored at 20 or higher on the CIWA-Ar scale, can lead to seizures or delirium tremens. People with severe symptoms usually need hospital inpatient detox for close monitoring and stronger medicines through an IV.
That is where the two settings overlap. A person with severe or complicated withdrawal may need a hospital. A person who is stable enough, and who plans ahead, may be able to do withdrawal management in a supervised residential setting. A clinical assessment decides which one, which is why calling an admissions team before you stop can matter so much.
Our safety guide to substances requiring medical detox covers alcohol, opioids, benzodiazepines and others. Older adults have extra considerations, covered in detox for seniors. People using cocaine should read about cocaine withdrawal management.
Why a home detox is not the middle path
When the ER feels like too much and treatment feels too far off, quitting at home can look like the compromise. It isn’t a safe one for many people.
WebMD describes home detox as generally going it alone, without professional guidance or medication. It adds that people who detox at home without following up with an appropriate treatment program may be more likely to relapse, and face a higher risk of overdose if they do, because tolerance has dropped.
If you or a loved one is planning to stop drinking, Kaiser Permanente’s advice is to talk to a doctor first about how you plan to stop. It also suggests removing all alcohol from the home, including medicines, rubbing alcohol and flavorings like vanilla extract, avoiding people you used to drink with, and considering a support group such as Alcoholics Anonymous.
We explain the risks in more detail in why supervised detox is necessary.
How families can help right now
If someone you love is drinking or using heavily, you do not have to wait for them to ask. The VA guidance says watchful waiting is not a good choice if you or others are being hurt by someone’s drinking. It says to seek help even if the person does not seek treatment.
A practical order of operations:
- Check for emergency signs first. Use the lists above. If any are present, call 911.
- Stay with the person if withdrawal has started and they are drinking heavily or using opioids, especially if they have had seizures or severe withdrawal before.
- Gather the facts. Note what they use, how much, when they last used, any medications, and any mental health diagnoses. Clinicians will ask.
- Call for a treatment referral. SAMHSA’s National Helpline, 1-800-662-HELP (4357), is a free, confidential service that runs 24/7 in English and Spanish.
- Call an admissions team and ask whether a medical assessment can happen the same day.
- Plan the handoff. Whether the start is an ER or a detox bed, decide where the person goes after.
If the ER is where you end up, ask the staff three things before discharge: what was treated, what follow-up is recommended, and who can help with a treatment referral.
Our perspective
Families usually call us at the worst hour, and the first thing we tell them is simple: if it is an emergency, hang up and call 911. We will never pretend a residential bed replaces an emergency room when someone is seizing or not breathing.
What we do see is the other half of the story. When people can reach a medically supervised setting before a crisis, withdrawal can be managed deliberately instead of by accident. We are a six-bed residential center, and that size shapes how we work: a small team that knows each person, comprehensive assessments, and a custom care plan from the first day. We are licensed by the California Department of Health Care Services and hold Joint Commission accreditation.
We also treat addiction and co-occurring mental health conditions together, because withdrawal rarely arrives alone. Anxiety, depression and trauma often surface the moment a substance is removed. Medication management with psychiatric oversight and dual diagnosis care are part of the plan, not a referral to somewhere else.
Detox is the beginning. The strongest outcomes we aim for come from a program that does not stop when the worst symptoms do. That is why we connect medical detox to residential treatment and behavioral rehabilitation instead of treating them as separate decisions.

FAQ
Will the ER help you detox?
The ER will treat dangerous withdrawal symptoms such as seizures, breathing problems or a racing heart. If you are not having a medical emergency, many emergency rooms are not equipped to treat addiction and may refer you to a local treatment center. Ask about follow-up care before you leave.
How is medical detox different from going to the ER?
The ER focuses on stabilizing an emergency and deciding whether you need to be admitted. Medical detox is a planned stay for managing withdrawal with continuous monitoring, and counseling can begin at the same time. Detox is the better fit when you are not in crisis but need supervision to stop safely.
Can I detox at home instead?
For heavy alcohol use in particular, no. Kaiser Permanente warns that severe alcohol withdrawal can be fatal, and WebMD notes that home detox without follow-up care carries higher relapse and overdose risks. Talk to a doctor or call an admissions team before you stop.
Who do I call if I’m not sure it’s an emergency?
If you see any emergency sign, call 911. If you’re unsure and the person is stable, SAMHSA’s National Helpline is free, confidential and open around the clock for referrals. You can also call an admissions team and describe what is happening.
