A drug withdrawal emergency means calling 911 or going to the ER now. Do this if you see a seizure, severe confusion, trouble waking or breathing, or suspect an overdose. You do not need to know the drug name first.
If someone is in danger or may hurt themselves, call 911. If you have suicidal thoughts but are safe, call or text 988.
If there are no emergency signs, talk to a doctor soon. They can help you find the right care. We run a treatment directory. We are not a treatment provider. See our guide to finding drug detox care for more steps.
Drug Withdrawal Emergency: When to Go to the ER
Call 911 now for a seizure, severe confusion, hallucinations, a high fever or racing heart during withdrawal, or any suspected overdose. Do not drive yourself to the hospital.
During alcohol withdrawal, seizures, fever, severe confusion, hallucinations, or irregular heartbeats require emergency care.[1] Stopping benzodiazepines suddenly after regular use can cause serious, potentially life-threatening withdrawal, including seizures or delirium.[2] For suspected opioid overdose, inability to wake or slow or shallow breathing are signs; call 911 now.[3] Do not wait to identify the drug.
- Spot the danger. Watch for the emergency signs listed above.
- Call 911 now. Follow the dispatcher's instructions and stay with the person.
- Tell responders what happened. Mention possible withdrawal or overdose.
For thoughts of suicide or self-harm, call or text 988 now. If the person may act soon or is in immediate danger, call 911 now.

Dangerous Drug Withdrawal Symptoms Differ by Substance
Treatment needs are assessed individually, considering biomedical, psychological, and social factors.[4] Do not use the time of day to decide whether symptoms are safe.
Alcohol withdrawal can be life-threatening.[5]
6–24 hours
after stopping or cutting back, alcohol withdrawal symptoms typically begin[6]
8–48 hours
after the last drink, alcohol withdrawal seizures can occur[6]
72–96 hours
after the last drink, alcohol withdrawal delirium often appears[6]
These ranges are estimates for alcohol withdrawal only, not a prediction for an individual case.[6] They are not a safe waiting period. Do not wait for a specific symptom to appear before seeking help.
For any substance, call 911 or go to the nearest emergency room now for danger signs, including seizures, severe confusion, hallucinations, a high fever or racing heart during withdrawal, signs of an overdose, or immediate danger from suicidal thoughts. If you have suicidal thoughts but are safe and not in immediate danger, call or text 988.
| Substance | Broad Risk Considerations | Safe Next Step |
|---|---|---|
| Alcohol | Seizures and delirium can occur during withdrawal.[6] | Call 911 or go to the nearest ER for danger signs. |
| Benzodiazepines | Withdrawal can be severe and potentially life-threatening.[2] | Without danger signs, contact a doctor promptly. |
| Opioids | Withdrawal can include vomiting and diarrhea.[7] | Without danger signs, contact a doctor or treatment program. |
| Stimulants | Suicidal thoughts without immediate danger: call or text 988. | For immediate danger or risk of acting, call 911 or go to the nearest emergency room now. |
If the person is pregnant, using multiple substances, has serious health conditions, or symptoms are worsening, contact a doctor promptly only if no danger signs are present. For danger signs, use the emergency steps above. For more information, read our guide on life-threatening alcohol withdrawal signs.
Withdrawal or Overdose? Treat Uncertainty as Urgent
If you are unsure whether someone is experiencing withdrawal or an overdose, treat the situation as urgent. Do not rely on timing alone to decide what to do; act on the warning signs you see.
| Possible Withdrawal Signs | Possible Overdose or Other Emergency Signs |
|---|---|
| Alcohol withdrawal can begin after a person stops or substantially reduces alcohol use.[6] | Inability to wake up[3] |
| Opioid withdrawal can cause vomiting and diarrhea.[7] | Slow or shallow breathing[3] |
| Unresponsiveness or trouble breathing[3] | |
| Seizures, severe confusion, hallucinations, high fever, or racing heart[1][6] |
Action: If the person is stable and has no danger signs, contact a clinician or detox service promptly about withdrawal care. If you see signs of overdose, call 911 or go to the nearest emergency room now.[3]
During suspected withdrawal, seizures, severe confusion, hallucinations, a high fever, or a racing heart are danger signs.[1][6] If any occur—or the person is unresponsive, cannot be woken, or has slow or shallow breathing—call 911 or go to the nearest emergency room now.[3] These signs require emergency evaluation regardless of whether withdrawal or overdose is suspected.
If you suspect an opioid overdose, call 911 right away.[3] If naloxone is available, give it and repeat it as directed by the product or dispatcher; this does not replace calling 911. Follow the dispatcher’s instructions while you wait for help. Do not wait to identify the substance before acting.

ER or Medical Detox: Where Should You Go?
The right place depends on how urgent the situation is. The ER handles immediate, life-threatening risks. Medical detox offers supervised care for stable people.
- Check for danger signs. If you see seizures or severe confusion, call 911 or go to the ER now.
- Call a clinician or program. If there are no danger signs, call a doctor or detox program. Describe the symptoms and ask if they can help.
- Confirm medical support. Before you travel, check what medical help is available at the facility.
- Watch for changes. If symptoms get worse, stop and get emergency help right away.
| Feature | Emergency Room | Medically Supervised Detox |
|---|---|---|
| Purpose | Fixes urgent medical issues and stabilizes critical conditions[8] | Manages withdrawal under supervision as part of broader care[9] |
| When to Go | When danger signs are present or the person is unstable | When the person is stable and a clinician confirms the program fits their needs[4] |
The ER is the right choice for emergencies. Hospitals must screen and stabilize patients with emergency conditions, even if they cannot pay.[8] This means what to expect during emergency addiction care includes quick safety checks and stabilization.
Medical detox is different. It manages withdrawal symptoms under supervision. It is not always the same as ongoing treatment for substance use disorders.[9] Guidelines say withdrawal care should lead to continuing treatment, not stand alone.[9] Providers use individual assessments to guide care levels.[4] Always check with a provider if they can manage specific symptoms before you arrive. You can view our list of medically supervised detox programs to find local options.
Medical Detox Near Me: Find Appropriate Care
Finding the right care is a key step. If you have urgent symptoms, go to the emergency room or call 911 now. Do not wait for a directory search. Do not wait for an insurance approval.
For non-emergency cases, start with your doctor or health plan. You can also call SAMHSA’s National Helpline. It is free and confidential.[10] FindTreatment.gov helps you find services in the U.S.[11]
Tell the program what substances are involved. Share your current symptoms. Ask if they can safely manage your needs. Also ask about their medical staff and emergency plans. Check how they help you get ongoing care after detox. If you have questions about an exposure, call Poison Control at 1-800-222-1222.[12]

Medicines, Symptom Relief, and Unsafe Home Remedies
Withdrawal treatment depends on the drug and your health. A clinician checks your body and makes a plan. This often includes monitoring and supportive care. Treatment choices are based on an individualized assessment of your specific needs.[4]
It is important to distinguish between medicines used to manage acute withdrawal symptoms and medications prescribed for ongoing substance use disorder treatment. For example, while methadone, buprenorphine, and naltrexone are FDA-approved for treating opioid use disorder,[3] clinicians may also use specific agents like lofexidine to help mitigate opioid withdrawal symptoms during discontinuation.[13] Similarly, doctors can prescribe medications to address alcohol withdrawal symptoms and make the process safer,[5] but this management is a component of broader treatment rather than a standalone cure.[9]
| Substance | What clinicians may consider | What you should not try on your own |
|---|---|---|
| Alcohol | Supervised medication and monitoring to make the process safer[5] | Stopping abruptly without medical supervision or using unapproved remedies |
| Benzodiazepines | Clinician-managed care plans tailored to individual needs | Attempting a home taper or adjusting doses without professional guidance |
| Opioids | FDA-approved medications for opioid use disorder, such as methadone, buprenorphine, and naltrexone[3] | Using leftover prescriptions or mixing substances to ease discomfort |
| Stimulants | Assessment and supportive care to manage symptoms | Relying on over-the-counter products or supplements without medical advice |
Safe symptom relief while arranging care involves supportive measures like staying hydrated and resting, but these do not replace medical oversight. Because withdrawal can progress rapidly, do not rely on over-the-counter products or supplements to manage symptoms without medical advice. A doctor or pharmacist can guide you on what is safe for your specific situation. Do not guess or mix treatments on your own.
Can Benadryl help with withdrawal symptoms? No evidence says it is safe for this purpose. Over-the-counter drugs can hide serious signs. They may also cause bad reactions with other meds. Talk to a licensed pro before taking anything new.
Never wait for a home fix if you need emergency care. Call 911 or go to the ER if you are in danger. Ask your doctor about any medicine questions first. They know your health history best.
What to Expect at the ER and What to Tell Staff
Emergency staff will focus on your immediate safety. They check your vital signs and ask about your symptoms. Tests depend on what they find. There is no single test for every type of withdrawal. Care depends on your symptoms and health history.
Honesty helps them treat you safely. If you are unsure about substances, say so. Do not wait for help until you have all the details.
- State the main concern. Tell the nurse or doctor you worry about drug withdrawal or an overdose.
- Share what you know. List substances you think are involved and when you last used them.
- Mention other factors. Note any prescriptions, other drugs, pregnancy, or health issues.
- Ask about next steps. Ask what they found and what care they suggest next.

Frequently Asked Questions
What should I give someone who is withdrawing?
Do not give alcohol, drugs, or other meds. Do not use over-the-counter remedies for withdrawal. Stay nearby if it is safe. Help the person get medical care. Call 911 or go to the ER now for danger signs. This includes seizures, severe confusion, or a fast heart rate. If you are unsure what was taken, call Poison Control. Do not delay emergency care.
Can Benadryl help with withdrawal symptoms?
Do not use Benadryl for withdrawal without advice. Talk to a clinician or pharmacist first. It can be risky with alcohol or sedatives. Other substances may also cause issues. Get professional advice before adding any new medicine.
Are panic attacks a symptom of withdrawal?
Panic-like feelings can happen during withdrawal. They do not prove a panic disorder exists. New or bad symptoms need a medical check. Use emergency care for danger signs like confusion. Also go to the ER for hallucinations.
What medicines are used to treat withdrawal symptoms?
Treatment depends on the substance and health status. A clinician may use supervised meds and monitoring. The FDA approved lofexidine for adult opioid withdrawal.[13] Do not take or give meds without guidance. Never use someone else’s prescription.
What is the hardest addiction to quit?
There is no single answer for everyone. How hard it feels varies by person. Medical danger is a different issue than difficulty. A clinician can check your specific risks and needs.[4] They look at your health and support system too.
What drug has the most severe withdrawal symptoms?
No universal ranking predicts your specific risk safely. A clinician can check your situation and pick the right care setting.[4]
Why is withdrawal worse at night?
Symptoms may feel more noticeable at night when things are quiet or there are fewer distractions, but what contributes varies by person. The time of day is not a reason to delay care. Vomiting and diarrhea are common opioid withdrawal signs.[7] For seizures, severe confusion, hallucinations, a high fever or racing heart during withdrawal, call 911 or go to the nearest ER now.[1] Signs of an overdose, such as being unable to wake or slow or shallow breathing, require a 911 call now.[3] For thoughts of suicide or self-harm, call 911 or go to the nearest ER now; for suicidal thoughts, call or text 988. For worsening symptoms without these danger signs, contact a clinician.
