Cutting back or stopping opioids causes physical and mood changes. Early on, you may feel anxious, restless, sweaty, or have a runny nose, tears, or yawns.[1] Later, belly cramps, diarrhea, vomiting, nausea, and goosebumps may appear.[1] Signs usually show up within 12 hours of the last heroin use and 30 hours after the last methadone dose, but timing varies.[1] A health professional can look at your case to see if you need medical withdrawal care.[2]

Our site is a treatment directory, not a treatment provider. What you read here is general info, not medical advice.

If you think someone is overdosing, call 911 now. If you have thoughts of hurting yourself, call or text 988.[3] For free help finding care, call the SAMHSA National Helpline at 1-800-662-HELP (4357).

Signs and Timing of Opioid Withdrawal

This process causes physical and emotional discomfort. Knowing common patterns can help you get ready.

Think of these times as a guide, not a sure thing. Your own schedule depends on the kind of opioid you took. It also depends on your past use and your health.

  1. Onset

    Symptoms may begin after you cut back or stop using opioids.

  2. Peak

    Discomfort often gets worse or changes as your body adjusts.

  3. Resolution

    Symptoms usually ease over time as your body recovers.

There is no strict five-step order for withdrawal. Signs change from one person to the next. They can show up in a different order.

Possible early symptomsPossible later or additional symptoms
YawningAbdominal cramps
TearingDiarrhea
Runny noseNausea
SweatingVomiting
RestlessnessGoosebumps
AnxietyMuscle aches

The table shows typical examples. Strong worry and bad sleep hit some people hard. For help, read our guide on managing anxiety and sleep issues.

Opioid Withdrawal: When to Seek Urgent or Emergency Help

Some signs during this process are dangerous. They need emergency help right away.

If you see signs of an overdose, call 911 now. Watch for a person who will not wake up. Breathing that is slow, shallow, or has stopped is also a red flag.

Bad vomiting and diarrhea can go on for a while. This can bring on dehydration.[4] If someone cannot hold down liquids, get help quickly. Fainting is another reason to seek quick care.

Know the difference between emergency care and referrals. The SAMHSA National Helpline provides details on locating treatment. It does not give emergency care. It does not handle withdrawal symptoms.

For suicidal thoughts or emotional distress, use the 988 Lifeline. You can get support via call, text, or chat 24 hours a day.[3]

Pick your next step using this safety check. This tool does not provide a diagnosis.

Opioid Withdrawal Safety Check

  1. Are your withdrawal symptoms getting worse?
  2. Are you unable to keep fluids down?
  3. Do you see signs of an overdose?
  4. Have you had a seizure?
  5. Are you very confused or seeing things?
  6. Do you have a high fever or racing heart?

This self-check is for information only and isn't a diagnosis.

Medical Withdrawal Management: What to Expect

The right setting for withdrawal management should fit a person’s clinical needs and circumstances.[2]

  1. Contact a qualified service. Call a licensed treatment center or your doctor to start.
  2. Complete an individualized assessment. Ask how the clinician will assess your needs, what health history and other substance use information to share, and how the assessment will help determine an appropriate setting.[2]
  3. Discuss a monitored plan. Ask the care team what monitoring and support they can provide, how they may help manage symptoms, and what to do if your symptoms change or you feel unsafe.
  4. Arrange continuing treatment. Before you leave, confirm your next steps. Ask how ongoing treatment and follow-up visits will work.

Licensed clinicians deliver the care described here. This is not a guide for quitting opioids on your own at home. Talk to a healthcare provider about the support and monitoring that may be available.

Check our guide on detoxing at home safely to see why professional help is key. Before you change your substance use or treatment plan, speak with a healthcare provider about your situation.

Can You Handle Opioid Withdrawal at Home?

A symptom checklist cannot show which care setting fits you. The American Society of Addiction Medicine (ASAM) notes that your specific health needs decide the right setting.[2] Only a licensed clinician can make that call. They must check your full health history first.

Comparison of Home without help and Outpatient medical care, Compare care settings before choosing. Who helps you: Family or friends only vs. Doctors and nurses; What they check: No medical checks or safety plan vs. Regular visits, vitals, and…

The table below lays out three common care settings. Not one of these is safe for all people. They do not replace a professional check-up.

Care SettingWho Helps YouWhat They CheckWhat to Ask
Home without professional helpFamily or friends onlyNo medical checks or safety plan"Is it safe for me to stay home, or do I need medical help?"
Outpatient medical careDoctors and nursesRegular visits, vitals, and medicine changes"How often will I be seen? What if I feel worse?"

If you think about detoxing at home safely, read our guide on home safety steps. First, always get a professional check.

Before you change how you use prescribed opioids for pain, speak with your prescriber.[5]

Is Benadryl Good for Opioid Withdrawal?

Benadryl is not a replacement for professional assessment or withdrawal treatment. It does not treat the key physical symptoms of the condition.

After Withdrawal: Ongoing Treatment and Overdose Prevention

Getting through withdrawal is a big first step, but it is not the finish line. It can help recovery continue past the acute phase.[6]

Methadone, buprenorphine, and naltrexone are FDA-approved medications for this condition.[7] A qualified clinician can talk through your options with you. They help you find what fits your needs.

Taking a break from opioids can lower your body’s tolerance. Going back to the same dose is very risky. A dose that felt fine months ago could cause an overdose now. This danger is real. You need a clear safety plan before you leave detox.

Talk to your clinician or a support person about naloxone. Discuss an overdose-response plan, too. Naloxone is a medicine that can reverse an opioid overdose.[8] Knowing how to use it can save lives. You can also read about naltrexone safety and withdrawal to learn more about long-term care.

Locating Medical Aid and Key Queries

Clear paths to get help are open to you. The SAMHSA National Helpline costs nothing and keeps things private. You receive info and referrals from it. It is not a treatment center. It is not an emergency service. If you are in danger, call 911 or go to the ER now.

For most people, calling a facility is the next move. Ask targeted questions to see their offerings. Check these few points:

  • What pre-start evaluation occurs?
  • What support is available if symptoms worsen?
  • What steps do they take for follow-up care?
  • What insurance and cost details need confirmation?

What your plan covers is up to that specific policy. Marketplace and many small-group plans must cover mental health and substance use services.[9] Yet the exact details differ by plan.[9] Federal parity rules apply to many such plans. They generally require that limits on these services not be stricter than those for medical and surgical care.[10] This does not mean benefits or limits must be identical, nor does it guarantee every plan covers these services. Check your benefits directly, as rules hinge on your plan and the law. Reach out to your insurer and the program first.

Frequently Asked Questions

How long do withdrawal symptoms usually last?

There is no single timeline for everyone. The ranges in this guide are just general guides. They are not a personal forecast. If your symptoms worry you, talk to a doctor. Do not wait for a specific date to pass.

What are the five stages of withdrawal?

There is no fixed five-stage list for everyone. Doctors describe common patterns and timing. Use this info as a general guide only. Do not use it to guess your own condition.

Can withdrawal be managed safely at home?

It depends on your health. Do not use online lists to pick your care level. Talk to a doctor to check your needs. This is key if symptoms are bad or getting worse. It is also key if you have other health issues.

Can Benadryl help with withdrawal symptoms?

Do not rely on Benadryl to treat withdrawal. Do not mix it with opioids or other sedatives on your own. Ask a doctor or pharmacist first. They can tell you what is safe for you.

What treatment or support can follow withdrawal management?

Ask about next steps before you leave care. This includes ongoing treatment and overdose prevention. Some meds for opioid use disorder can also help with pain.[11] People with pain may be advised to keep using them.[11] Talk to a clinician about your plan and how long it should last.

When should vomiting or diarrhea during withdrawal prompt medical help?

Call a doctor if symptoms are severe or won't stop. Call if you cannot keep fluids down. If you faint or get confused, call 911 now. Or go to the nearest emergency room right away.
