What does "alcohol withdrawal" really mean?

Alcohol withdrawal is a catchall term that refers to the group of symptoms that occur when someone suddenly stops or reduces their drinking—the time period that is commonly called detox. Withdrawal symptoms include psychological effects (like cravings and anxiety) and physical effects (like sweating and high blood pressure). While withdrawal is uncomfortable when someone stops many substances, alcohol withdrawal, in particular, brings serious medical risks. 

The good news is that alcohol withdrawal is temporary. For most people, the worst is over in under a week. 

The risks of alcohol detox

Since alcohol is readily available across the country, it’s common to think of it as safe. Even when problems with alcohol use disorder (often referred to as alcoholism or alcohol abuse) arise, many people think that they’ll be fine if they just stop drinking. To be clear, quitting drinking or moderating your alcohol intake is an excellent goal, and we support it. But it’s important to be aware of the risks of alcohol detox so you can be prepared if they crop up after you stop or reduce your drinking.

Many people detox from alcohol at home, but it is important to have trusted people check in regularly. Because there are health risks and a chance of death, people with a history of experiencing delirium tremens or withdrawal-induced seizures should seek medical supervision.


Alcohol withdrawal symptoms

Alcohol withdrawal symptoms can begin sooner than many people realize—usually less than 8 hours after the last drink. They can also occur days after stopping drinking.

The most severe symptoms of alcohol withdrawal include seizures and hallucinations, which manifest 1 to 2 days after withdrawal symptoms begin, and delirium tremens (DTs). DTs can develop between 1 and 4 days after withdrawal starts. They are characterized by disorientation and often include severe agitation, rapid heartbeat, high blood pressure, and fever. They can cause heart attack and stroke. About five percent of the patients who experience DTs die.

Common alcohol withdrawal symptoms

  • Anxiety
  • Headache
  • Fatigue
  • Irritability
  • Shakiness or tremors
  • Nausea
  • Sweating
  • Insomnia
  • Rapid heart rate

Symptoms of delirium tremens

Delirium tremens (DTs) is very serious and dangerous, and can occur during alcohol withdrawal. DTs usually arise between 1 and 3 days after stopping drinking. Seek emergency medical care if these symptoms occur.

  • Confusion/disorientation
  • Agitation
  • Fever
  • Hallucinations (seeing, hearing, or feeling things that aren’t there)
  • Seizures
  • High blood pressure
  • Loss of consciousness

Coping with withdrawal symptoms

If you’re detoxing at home (without medical supervision), your best option is to plan the kinds of comfort that usually help when you’re sick. If possible, stay in a quiet, calm environment away from disruptions. Keep hydrated with water and electrolyte drinks like coconut water or sports drinks. Wear comfortable clothing, and have changes of clothes available so you can change them if you get sweaty and chilled. Your appetite may be affected, but try to have small, frequent meals, like yogurt or soup. Music, television, books, or other forms of entertainment can help your thoughts from spiraling into negativity.

If you are undergoing medical supervision for your detox, your providers may prescribe medications to help ease the discomfort of withdrawal. Even if a home detox was the plan, anyone who begins to experience hallucinations or seizures should seek emergency medical assistance immediately.

Post-acute withdrawal syndrome

Many people experience withdrawal symptoms for a prolonged period of time, beyond the typical 1-2 week window. This extended process of withdrawal is called post-acute withdrawal syndrome (PAWS). PAWS often recurs periodically in episodes of a few days and can fluctuate in severity. These episodes can persist for up to two years. It is estimated that up to 75% of heavy drinkers who quit alcohol may experience PAWS to some extent.

Common symptoms of PAWS:

  • Irritability
  • Cravings
  • Apathy
  • Anxiety or panic
  • Depression
  • Insomnia
  • Mood swings
  • Low energy/fatigue
  • Chronic pain
  • Difficulty with cognitive tasks (remembering things, learning, problem-solving)

PAWS symptoms can be triggered or made more severe by stressful situations, but they can also recur without any obvious triggers. If PAWS causes you distress, speak with your healthcare provider.


Medication-assisted treatment for alcohol use disorder

There are FDA-approved medications that help to control alcohol cravings and stabilize long-term recovery.


Naltrexone (ReVia) belongs is a group of medications called opioid antagonists. It reduces the motivation to drink by blocking the reinforcement or reward of alcohol. Over time, this begins to change the brain’s reaction to alcohol, and many people find that they lose interest in drinking. It is also used in opioid addiction recovery. Naltrexone can be taken by those who are moderating their drinking and by those who have stopped drinking entirely. It should not be taken by those who are using opioids, as it can precipitate opioid withdrawal. Naltrexone is usually well tolerated. The main side effects may be digestive upset, tiredness, headache, and dizziness, which usually pass.

Acamprosate (Campral)

Acamprosate (Campral) is believed to act by correcting some of the brain changes caused by chronic alcohol consumption. Drinking affects some of the neurotransmitters that make you feel calm, and when you quit drinking you can feel poorly because of this. Acamprosate decreases these uncomfortable symptoms by affecting neurotransmitters in the brain that cause excitability. Acamprosate works best after you’ve quit drinking entirely, rather than while you are still drinking. It does not have a high potential addiction risk. Acamprosate is usually well tolerated. The main side effect may be diarrhea, which should be mild and usually passes quickly.

Medications for withdrawal

Some doctors prescribe medications to relieve the discomfort of alcohol withdrawal. These can include gabapentin and topiramate, which are intended for other purposes but have been discovered to be helpful for some people with alcohol use disorder. Your healthcare provider can also suggest over-the-counter medications to relieve discomfort from alcohol withdrawal symptoms.

Physicians may also prescribe benzodiazepines—diazepam, chlordiazepoxide (Librium), clonazepam (Klonopin), etc.—to those in withdrawal from alcohol use.
