How Long Does Alcohol Detox Take?
Apr 09, 2026This is a common question people ask when starting recovery. Knowing how long alcohol detox will take allows them to plan their lives around treatment. It also helps them understand what to expect.
To answer the question, alcohol detox typically takes one to two weeks. However, there are factors that could impact its duration. This article will outline the process to prepare you for what's ahead.
The Standard Alcohol Detox Timeline
Alcohol detox typically follows a timeline with withdrawal symptoms changing and getting more and less severe. The process may look something like this:
-
6-12 hours after your last drink: Alcohol withdrawal typically begins, with symptoms including anxiety, tremors, nausea, and headaches
-
12-24 hours after your last drink: Severe withdrawal symptoms typically begin with a risk of hallucinations
-
24-48 hours after your last drink: This is the peak danger window with a high seizure risk. According to a 2024 NIH study, 50% of AUD patients develop alcohol withdrawal syndrome, and 20% of those individuals experience seizures.
-
48-72 hours after your last drink: Delirium tremens risk increases, making this the most critical detox window. According to a Science Direct study, DTs occur in 3% to 5% of patients and carry a mortality rate below 1% thanks to modern medicine.
-
72 hours to 7 days: Symptoms of alcohol withdrawal gradually fade.

What Influences Detox Duration
While alcohol withdrawal symptoms typically fade within a week, they can take longer. Here are some factors that influence their duration:
-
Drinking History: People who drink alcohol heavily for prolonged periods may experience longer withdrawal timelines.
-
Number of Prior Withdrawals: Given the Kindling Effect, people who have gone through multiple detoxes will experience more severe symptoms with each attempt
-
Age: Older individuals may not recover as quickly due to health complications and slow metabolisms
-
Overall Physical Health: People with abnormal liver function, poor heart health, and inadequate nutritional status may experience prolonged detox periods
-
Co-Occurring Disorders: Individuals with mental health conditions may experience detox symptoms that severely impact their emotional health for extended periods
-
Polysubstance Use: The use of other substances alongside alcohol abuse complicates and prolongs detox
-
Biological Sex: Research reveals women may be more sensitive to alcohol's neurological effects
Post Acute Withdrawal Symptoms (PAWS)
Although withdrawal symptoms gradually dissipate within one to two weeks, some may experience Post Acute Withdrawal Symptoms (PAWS), a condition in which symptoms persist beyond the typical window, lasting weeks, months, or even years. It is more likely to occur in individuals at high risk for prolonged withdrawal due to age, mental and physical conditions, polysubstance use, and severe alcohol use disorder. Symptoms typically include:
-
Anxiety and depression
-
Sudden mood changes and emotional dysregulation
-
Sleep disturbances and insomnia
-
Cognitive fog and memory issues
-
Alcohol cravings
While PAWS does not present a direct health risk or life-threatening symptoms, it can increase the risk of relapse. It is treated with ongoing detox care, including medication and therapy, and will go away in time.

FAQs
When is alcohol withdrawal most dangerous?
Severe alcohol withdrawal kicks in within 24-72 hours after the last alcohol consumption. Seizure risk is highest in the 24-48 hour window, while the 48-72 hour window presents a high risk of delirium tremens, the most dangerous withdrawal symptom. Risks decrease after those windows, but don't completely go away until detox is complete.
What are the first signs that alcohol detox has started?
An individual will typically experience alcohol withdrawal symptoms within 6-12 hours after they last drink alcohol. Early symptoms include mild anxiety, restlessness, hand tremors, nausea, headache, sensitivity to light and sound, and elevated heart rate. Many people think these are signs of a hangover and ignore them until they become more severe.
Is it safe to detox from alcohol at home?
It can be safe to detox from alcohol at home, especially if this is your first or second detox, you didn't have a severe alcohol use disorder, and you are experiencing mild symptoms. However, medical guidance is always recommended.
