Alcohol Withdrawal

What is alcohol withdrawal?

Alcohol withdrawal is a physical or mental sickness that happens when you drink alcohol daily and suddenly stop drinking. It can begin within 10 hours of your last drink and gets worse over 2 to 3 days. 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. The symptoms may be mild at first, and get worse as your body goes through the detoxification process. Detoxification means your body is working to remove the alcohol. Severe symptoms of alcohol withdrawal are often called delirium tremens (DTs). DTs usually occur 3 to 4 days after you stop drinking. You may have any of the following signs and symptoms:

  • Seizures 24 hours to 1 week after your last drink

  • Confusion and trouble remembering

  • Fever, sweating, shakiness, and a fast heartbeat

  • Hallucinations (you see, hear, feel, or taste things that are not there)

  • Nausea and vomiting

  • Nervousness and agitation

  • Poor sleep, restlessness, or nightmares

How is alcohol withdrawal diagnosed?

  • Neurologic exam: This is also called neuro signs, neuro checks, or neuro status. A neurologic exam can show healthcare providers how well your brain works during alcohol withdrawal. Healthcare providers will check how your pupils react to light. They may check your memory, balance, and hand grasp.

  • Blood tests: You may need blood taken to test for the amount of alcohol in your body. The tests can also show if you have low levels of vitamins and electrolytes, or organ damage. The liver and pancreas are commonly damaged by alcohol.

  • Urine sample: A sample of your urine may be collected and sent to a lab to test for alcohol.

  • Chest x-ray: Healthcare providers use these pictures of your lungs and heart to look for signs of infection, such as pneumonia.

  • ECG: This is also called an EKG. An ECG is done to check for damage or problems in your heart. A short period of electrical activity in your heart is recorded.

  • A CT , or CAT scan, takes pictures of your skull and brain. You may be given contrast liquid before the scan. Tell a healthcare provider if you have ever had an allergic reaction to contrast liquid.

How is alcohol withdrawal treated?

  • Medicines:

    • Sedative: This medicine is given to help you stay calm and relaxed.

    • Anticonvulsant medicine: This medicine is given to control seizures. Take this medicine exactly as directed.

    • Antinausea medicine: This medicine may be given to calm your stomach and prevent vomiting.

    • Glucose: This medicine may be given to increase the amount of sugar in your blood.

    • Vitamin supplements: You may need to take supplements because alcohol kept your body from absorbing enough vitamins from food. Vitamins can also help prevent alcohol-related brain damage.

  • Breathing support:

    • You may need extra oxygen if your blood oxygen level is lower than it should be. You may get oxygen through a mask placed over your nose and mouth or through small tubes placed in your nostrils. Ask your healthcare provider before you take off the mask or oxygen tubing.

    • Ventilator: This machine breathes for you. A tube is put into your airway through your mouth or nose, or through a small incision in your throat. The machine gives you oxygen through the tube.

What are the risks of alcohol withdrawal?

You may act out violently when you go through alcohol withdrawal. You may harm yourself and others. You can have high fevers, abnormal heartbeats, and hallucinations. Severe alcohol withdrawal can be life-threatening.
