    Alcohol withdrawal

    Detoxification - alcohol; Detox - alcohol

    Alcohol withdrawal refers to symptoms that may occur when a person who has been drinking too much alcohol every day suddenly stops drinking alcohol.


    Alcohol withdrawal occurs most often in adults, but it may occur in teenagers or children.

    The more you drink every day, the more likely you are to develop alcohol withdrawal symptoms when you stop drinking.

    You may have more severe withdrawal symptoms if you have certain other medical problems.


    Alcohol withdrawal symptoms usually occur within 8 hours after the last drink, but can occur days later. Symptoms usually peak by 24 - 72 hours, but may persist for weeks.

    Common symptoms include:

    • Anxiety or nervousness
    • Depression
    • Fatigue
    • Irritability
    • Jumpiness or shakiness
    • Mood swings
    • Nightmares
    • Not thinking clearly

    Other symptoms may include:

    • Clammy skin
    • Enlarged (dilated) pupils
    • Headache
    • Insomnia (sleeping difficulty)
    • Loss of appetite
    • Nausea and vomiting
    • Pallor
    • Rapid heart rate
    • Sweating
    • Tremor of the hands or other body parts

    A severe form of alcohol withdrawal called delirium tremens can cause:

    • Agitation
    • Fever
    • Seeing or feeling things that aren't there (hallucinations)
    • Seizures
    • Severe confusion

    For more information on this severe form of alcohol withdrawal, see: Delirium tremens.

    Exams and Tests

    Your health care provider will perform a physical exam. This may reveal:

    • Abnormal eye movements
    • Abnormal heart rhythms
    • Dehydration (not enough fluids in the body)
    • Fever
    • Rapid breathing
    • Rapid heart rate
    • Shaky hands

    Blood and urine tests, including a toxicology screen, may be done.


    The goal of treatment includes:

    • Reducing withdrawal symptoms
    • Preventing complications of alcohol use
    • Therapy to get you to stop drinking (abstinence)


    People with moderate-to-severe symptoms of alcohol withdrawal may need inpatient treatment at a hospital or other facility that treats alcohol withdrawal. You will be watched closely for hallucinations and other signs of delirium tremens.

    Treatment may include:

    • Monitoring of blood pressure, body temperature, heart rate, and blood levels of different chemicals in the body
    • Fluids or medications through a vein (by IV)
    • Sedation using medication called benzodiazepines until withdrawal is complete


    If you have mild-to-moderate alcohol withdrawal symptoms, you can often be treated in an outpatient setting. You will need someone to commit to staying with you during this process and who can keep an eye on you. Daily visits to your health care provider are often needed until you are stable.

    Treatment usually includes:

    • Sedative drugs to help ease withdrawal symptoms
    • Blood tests
    • Patient and family counseling to discuss the long-term issue of alcoholism. See: Alcoholism
    • Testing and treatment for other medical problems linked to alcohol use

    It is important that the patient goes to a living situation that helps support them in staying sober. Some areas have housing options that provide a supportive environment for those trying to stay sober.

    Permanent and life-long abstinence from alcohol is the best treatment for those who have gone through withdrawal.

    Outlook (Prognosis)

    How well a person does depends on the amount of organ damage and whether the person can stop drinking completely. Alcohol withdrawal may range from a mild and uncomfortable disorder to a serious, life-threatening condition.

    Symptoms such as sleep changes, rapid changes in mood, and fatigue may last for months. People who continue to drink a lot may develop health problems such as liver, heart, and neurological disease.

    Most people who go through alcohol withdrawal make a full recovery. However, death is possible, especially if delirium tremens occurs.

    When to Contact a Medical Professional

    Alcohol withdrawal is a serious condition that may rapidly become life threatening.

    Call your health care provider or go the emergency room if you think you might be in alcohol withdrawal, especially if you were using alcohol often and recently stopped. Call for an appointment with your health care provider if symptoms persist after treatment.

    Go to the emergency room or call the local emergency number (such as 911) if seizures, fever, severe confusion, hallucinations, or irregular heartbeats occur.


    Reduce or avoid alcohol. If you have alcoholism, you should stop drinking completely.
