How Long Does Alcohol Withdrawal Last

Understanding Alcohol Withdrawal

Alcohol withdrawal is a challenging and potentially dangerous process that occurs when an individual who has been consuming alcohol heavily and regularly suddenly stops or significantly reduces their intake. Understanding the timeline and symptoms of alcohol withdrawal is crucial for those who may be going through it, as well as for their loved ones and healthcare providers.

Alcohol withdrawal syndrome (AWS) arises due to the abrupt cessation or reduction in alcohol intake. The body, accustomed to the presence of alcohol, undergoes a series of physical and psychological changes as it adjusts to the absence of alcohol. These changes can range from mild to severe and, in some cases, life-threatening.

Factors Influencing Alcohol Withdrawal Duration

Several factors influence the duration and severity of alcohol withdrawal:

Duration and Quantity of Alcohol Use: The longer and more heavily a person has been drinking, the more severe the withdrawal symptoms are likely to be.

Age and Health Status: Older individuals and those with pre-existing health conditions may experience more intense symptoms.

Genetic Factors: Genetic predisposition can play a role in how the body reacts to alcohol withdrawal.

Presence of Co-occurring Disorders: Mental health disorders or other substance abuse issues can complicate the withdrawal process.

Stages of Alcohol Withdrawal

The timeline of alcohol withdrawal can be divided into three primary stages: acute withdrawal, early abstinence, and protracted withdrawal.

Acute Withdrawal (6-72 Hours)

  • 6-12 Hours: Mild symptoms begin to appear, including anxiety, insomnia, nausea, abdominal pain, and mild tremors.
  • 12-24 Hours: Symptoms can escalate to include hallucinations (auditory, visual, or tactile), increased heart rate, and increased blood pressure.
  • 24-72 Hours: The risk of severe symptoms peaks, with the possibility of seizures and delirium tremens (DTs). DTs are characterized by confusion, rapid heart rate, high blood pressure, fever, and severe agitation.

Early Abstinence (3-14 Days)

  • 3-7 Days: Symptoms typically start to subside, but individuals may still experience anxiety, irritability, mood swings, and trouble sleeping.
  • 7-14 Days: Physical symptoms continue to improve, but psychological symptoms, such as anxiety and depression, may persist.

Protracted Withdrawal (Weeks to Months)

  • Weeks to Months: While the most intense symptoms generally fade within the first two weeks, some individuals may experience protracted withdrawal symptoms. These can include mood swings, sleep disturbances, and cravings, which can last for several months as the brain gradually adjusts to the absence of alcohol.

Managing Alcohol Withdrawal

Alcohol withdrawal can be dangerous and should ideally be managed under medical supervision, especially for individuals with a history of severe withdrawal symptoms. Treatment options include:

  1. Medical Detoxification: In a controlled environment, medical professionals can monitor vital signs, administer medications to ease symptoms, and provide supportive care.
  2. Medications: Benzodiazepines are often prescribed to manage withdrawal symptoms and prevent seizures. Other medications, like anticonvulsants and antipsychotics, may be used based on individual needs.
  3. Nutritional Support: Proper nutrition and hydration are essential during withdrawal. Thiamine (vitamin B1) supplementation is often necessary to prevent complications like Wernicke-Korsakoff syndrome.
  4. Psychological Support: Counseling and support groups can help individuals cope with the psychological aspects of withdrawal and establish long-term sobriety.

Long-term Recovery

Achieving and maintaining sobriety extends beyond the initial withdrawal period. Long-term recovery involves ongoing support, lifestyle changes, and, often, therapy. Joining support groups like Alcoholics Anonymous (AA) or engaging in cognitive-behavioral therapy (CBT) can provide the tools and community needed to sustain recovery.

Medication for Alcohol Withdrawal


Medications: Diazepam (Valium), Lorazepam (Ativan), Chlordiazepoxide (Librium)

Uses: Benzodiazepines are the first-line treatment for managing alcohol withdrawal symptoms. They help reduce anxiety, prevent seizures, and alleviate other withdrawal symptoms.


  • Diazepam: Initial dose of 10-20 mg every 4-6 hours as needed for the first 24 hours, then tapering down over 3-5 days.
  • Lorazepam: Initial dose of 2-4 mg every 4-6 hours as needed for the first 24-48 hours, then tapering down over 3-5 days.
  • Chlordiazepoxide: Initial dose of 50-100 mg, followed by 25-50 mg every 6 hours for the first 24 hours, then tapering down over 3-5 days.

Side Effects: Drowsiness, dizziness, confusion, respiratory depression, potential for dependence and withdrawal.


Medications: Carbamazepine (Tegretol), Valproic Acid (Depakote)

Uses: Anticonvulsants are used to prevent seizures, particularly in patients who may be at risk or have a history of seizures.


  • Carbamazepine: 200 mg every 6-8 hours initially, tapering over 5-7 days.
  • Valproic Acid: 500-1000 mg per day in divided doses, adjusted based on response and tolerability.

Side Effects: Drowsiness, dizziness, nausea, vomiting, liver toxicity (especially with Valproic Acid), hematologic abnormalities (especially with Carbamazepine).


Medications: Propranolol (Inderal)

Uses: Beta-blockers are used to manage cardiovascular symptoms of withdrawal, such as hypertension and tachycardia. They also help reduce anxiety and tremors.


  • Propranolol: 10-40 mg every 6-8 hours, adjusted based on clinical response.

Side Effects: Bradycardia, hypotension, fatigue, dizziness, gastrointestinal discomfort.

Alpha-2 Agonists

Medications: Clonidine (Catapres)

Uses: Clonidine is used to reduce withdrawal symptoms such as anxiety, agitation, and high blood pressure by decreasing sympathetic nervous system activity.


  • Clonidine: 0.1-0.2 mg every 6-8 hours, with a maximum of 1.2 mg per day.

Side Effects: Hypotension, bradycardia, dry mouth, sedation, dizziness.


Medications: Haloperidol (Haldol)

Uses: Antipsychotics can be used to manage severe agitation, hallucinations, or delirium tremens that may occur during alcohol withdrawal.


  • Haloperidol: 2-5 mg every 4-8 hours as needed, with a maximum daily dose of 20 mg.

Side Effects: Extrapyramidal symptoms (tremors, rigidity), sedation, hypotension, prolongation of the QT interval on the ECG, increased risk of tardive dyskinesia with long-term use.


What are the most common symptoms of alcohol withdrawal?

Common symptoms include anxiety, tremors, sweating, nausea, headaches, insomnia, and, in severe cases, seizures and delirium tremens.

How long do alcohol withdrawal symptoms last?

Symptoms can begin as early as 6 hours after the last drink, peak at 24-72 hours, and typically diminish within 1-2 weeks. However, some psychological symptoms may persist for months.

Can alcohol withdrawal be fatal?

Yes, severe withdrawal can lead to life-threatening conditions like seizures and delirium tremens. Medical supervision is strongly recommended.

What can help alleviate withdrawal symptoms?

Medical detox, medications (like benzodiazepines), nutritional support, and psychological counseling can help manage and alleviate withdrawal symptoms.

Is it possible to undergo alcohol withdrawal at home?

While mild withdrawal can sometimes be managed at home, it is safer to undergo detox under medical supervision, especially for individuals with a history of severe withdrawal symptoms or other health issues.


Alcohol withdrawal is a complex process that varies significantly among individuals. While the acute phase typically lasts a few days to a week, psychological and emotional recovery can take much longer. It is crucial for anyone undergoing alcohol withdrawal to seek medical advice and support to ensure a safe and effective detoxification process.
