Medically reviewed by Last updated on Jul 4, 2022.

What is alcohol withdrawal?

Alcohol withdrawal is a group of symptoms that occurs when you drink alcohol daily and suddenly stop. Withdrawal may also happen if you suddenly reduce the amount of alcohol that you normally drink.

What are the signs and symptoms of alcohol withdrawal?

The signs and symptoms of alcohol withdrawal normally start 4 to 24 hours after you stop drinking. Signs and symptoms may be mild at first and get worse over 2 to 3 days during the detoxification process. Detoxification means your body is working to remove the alcohol. You may have any of the following:

  • Headaches
  • Fever, sweating, shakiness, and a fast heartbeat
  • Confusion, trouble remembering, or hallucinations
  • Nervousness, anxiety, and agitation
  • Nausea and vomiting
  • Poor sleep, restlessness, or nightmares
  • Seizures 24 hours to 1 week after your last drink

What are delirium tremens (DTs)?

DTs are severe symptoms of alcohol withdrawal that can start 3 to 4 days after you stop drinking. DTs may include any of the following:

  • Fever
  • Feeling restless or agitated
  • Tremors
  • Constant hallucinations
  • Faster heartbeat and breathing than usual

How is alcohol withdrawal treated?

Your healthcare provider will ask how much and how often you drink. He or she will also ask how long it has been since you had your last drink. Blood or urine tests may be used to check the amount of alcohol in your blood. The tests may also show organ damage or low vitamin or electrolyte levels. The goal of treatment is to manage your symptoms and help prevent severe symptoms from developing. You may need to be treated in the hospital if you have severe withdrawal symptoms.

  • Medicines may be given to calm you and help manage your symptoms.
  • Vitamin supplements such as thiamine (vitamin B1) may be recommended. High alcohol intake can keep your body from absorbing enough vitamins from food.
