Alcohol Withdrawal Symptoms

Key Takeaways

  • Alcohol withdrawal symptoms occur when someone with alcohol dependence stops drinking or significantly reduces their intake, causing the nervous system to become hyperactive.
  • Symptoms range from mild (anxiety, tremors, sweating) to severe (seizures, delirium tremens) and typically begin within 6–12 hours after the last drink.
  • The alcohol withdrawal timeline usually peaks between 24–72 hours, with acute symptoms lasting 3–7 days for most people.
  • Medical detox provides 24/7 monitoring, medication management, and emotional support to ensure safe withdrawal and prepare you for ongoing recovery.

When someone who drinks heavily tries to stop or significantly reduce their alcohol intake, their body often responds with a range of physical and mental reactions. These responses are known as alcohol withdrawal symptoms, and they can range from mild discomfort to life-threatening complications. 

What Is Alcohol Withdrawal Syndrome?

The severity of alcohol withdrawal symptoms depends on several factors, including how long you’ve been drinking, how much you typically consume, your overall health, and whether you’ve experienced withdrawal before. 

Common Alcohol Withdrawal Symptoms

Alcohol withdrawal symptoms typically fall into several categories, ranging from mild to severe. Recognizing these signs early can help you or a loved one seek appropriate care.

Mild to Moderate Symptoms

In the early stages of withdrawal, symptoms often include:

  • Anxiety
  • Restlessness 
  • Irritability
  • Physical discomfort (tremors, excessive sweating, nausea, vomiting, headaches, difficulty sleeping) 
  • Heart racing or palpitations

Severe Symptoms

For some, alcohol withdrawal symptoms progress to more serious complications, including: 

  • Hallucinations 
  • Seizures
  • Delirium tremens (DTs)

Seizures represent one of the most dangerous aspects of alcohol withdrawal, but the most severe form of withdrawal is DTs, a potentially fatal condition characterized by severe confusion, profound disorientation, high fever, rapid heart rate, and intense hallucinations. Delirium tremens affects approximately 3-5% of people withdrawing from alcohol, but it can be fatal without proper medical treatment.

The Alcohol Withdrawal Timeline

The withdrawal timeline varies from person to person, but there are general patterns that most people follow. Understanding this timeline can help you prepare for what to expect and recognize when symptoms may be peaking.

6–12 Hours After Last Drink

Symptoms often begin within six to 12 hours after your last drink. During this initial phase, you might notice anxiety, shaking, headache, nausea, vomiting, and sweating. These early symptoms can be mild, but they signal that your body is beginning to react to the absence of alcohol.

12–24 Hours After Last Drink

As withdrawal progresses, symptoms typically intensify. Hallucinations may begin during this period, and some people experience their first seizures. This is a critical window when medical supervision becomes especially important.

24–48 Hours After Last Drink

The second day of withdrawal often brings peak symptom intensity for many individuals. Seizures are most likely to occur during this timeframe, and vital signs like blood pressure and heart rate may become unstable. If delirium tremens develops, it typically begins around this time, though it can occur later.

48–72 Hours + Beyond

For those experiencing severe alcohol withdrawal syndrome, delirium tremens most commonly manifests between 48 and 72 hours after the last drink, though it can appear up to a week later. The acute phase of withdrawal generally lasts three to seven days, with symptoms gradually subsiding. However, some people experience prolonged symptoms such as anxiety, insomnia, and mood changes that can persist for weeks or even months — a condition sometimes called post-acute withdrawal syndrome.

Four Reasons Medical Supervision Matters

Given the potential severity of alcohol withdrawal symptoms, attempting to detox on your own — sometimes called “going cold turkey” — can be dangerous and, in some cases, fatal. Medical detoxification provides several critical advantages that home-based withdrawal cannot offer.

  1. Healthcare professionals can monitor your vital signs around the clock, catching any dangerous changes before they become life-threatening. Second, medications can be administered to ease symptoms, reduce the risk of seizures, and prevent delirium tremens. 
  2. Medical detox addresses not just the physical aspects of withdrawal but also provides emotional support during an extremely vulnerable time. The psychological distress of withdrawal can be overwhelming, and having trained professionals who understand what you’re going through can make the experience more bearable.
  3. Finally, medical supervision sets the foundation for long-term recovery. Detox is only the first step in overcoming alcohol dependence. A structured treatment environment helps you transition from detox into therapeutic programs that address the underlying factors contributing to your alcohol use.

Risk Factors for Severe Withdrawal

Not everyone who stops drinking will experience severe alcohol withdrawal symptoms, but certain factors increase your risk. These include a long history of heavy drinking, previous episodes of alcohol withdrawal, concurrent mental health conditions, use of other substances, older age, and underlying medical conditions.

If you’ve experienced seizures or delirium tremens during a previous withdrawal attempt, your risk of experiencing them again is significantly higher. This history makes medical supervision even more essential for future detox attempts.

What to Expect in Medical Detox

Medical detox for alcohol withdrawal typically takes place in a specialized detox facility or hospital setting. Upon admission, healthcare providers conduct a comprehensive assessment of your drinking history, medical background, and current symptoms. This information helps them create an individualized treatment plan.

Throughout detox, your vital signs are monitored regularly, and medications are adjusted based on your symptoms. The care team closely monitors for signs of complications and intervenes promptly if your condition changes. Beyond managing physical symptoms, staff members provide emotional support and begin conversations about ongoing treatment options.

Medical detox generally lasts three to seven days, though some people require longer stays depending on the severity of their withdrawal. The goal is not only to help you through withdrawal safely but also to prepare you for the next phase of treatment, whether that’s residential care, a partial hospitalization program, or outpatient services.

Can you die from alcohol withdrawal?

Yes, alcohol withdrawal can be life-threatening without proper medical supervision. Severe complications like seizures and delirium tremens can be fatal if left untreated, making medical detox essential for anyone with a history of heavy drinking or previous withdrawal episodes.

What are the first signs of alcohol withdrawal?

Early symptoms can begin 6–12 hours after the last drink. Common first signs include anxiety, shakiness (tremors), sweating, nausea, headache, restlessness, and trouble sleeping. Withdrawal can worsen quickly, so it’s important to get medical guidance.

Is it safe to detox from alcohol at home?
