The alcohol withdrawal timeline outlines the stages and symptoms a person may experience when they stop drinking after heavy or prolonged use. In this article, you’ll find a high-level overview of how withdrawal typically progresses.
You’ll learn about the first signs that appear within hours, the more intense symptoms that may develop in the first few days, and how the process usually resolves.
Key Facts
- Nearly 1 in 10 U.S. adults has alcohol use disorder, making safe withdrawal management essential.
- Withdrawal progresses in phases: early symptoms begin within 6–24 hours, seizures may occur in 24–48 hours, and delirium tremens risk peaks at 48–72 hours.
- The timeline can be influenced by health, genetics, history of withdrawals, and support systems.
- Acute symptoms usually improve by days 4–7, but protracted symptoms like insomnia or cravings may last weeks.
- Medical supervision, CIWA-Ar scoring, and medications such as benzodiazepines improve safety and recovery.
- Detox is safest under professional care, with supervised settings recommended for higher-risk individuals.
Alcohol Withdrawal Timeline
Nearly 1 in 10 adults in the United States has an alcohol use disorder. Safely managing alcohol withdrawal symptoms is an important first step towards a life in recovery. Without proper care, withdrawal can bring serious health risks, which is why understanding both the immediate and longer-lasting symptoms is essential.
Acute vs. Protracted Symptoms at a Glance
The alcohol withdrawal timeline can be broken down into two phases: the acute and the protracted phase. The acute phase of withdrawal usually begins in the first six to 24 hours after your last drink and may last from seven days to two weeks.
The timeline windows typically include:
- 0-24 hours: Onset of symptoms
- 24-48 hours: Continued symptoms with increased risk of seizure activity
- 48-72 hours: Continued symptoms with risk of developing delirium tremens
- Days 4-7: Symptoms begin to improve
What Shifts the Timeline
It is essential to remember that each person’s recovery journey is unique, and for this reason, several factors can alter the withdrawal timeline.
Factors that can shift the alcohol withdrawal timeline include:
- Amount and frequency of alcohol use
- Duration of alcohol use
- Poor overall health, including dehydration and electrolyte imbalances
- Age
- Co-occurring mental health conditions
- Polysubstance use
- Genetics and family history
- Co-morbidities, including cardiac or liver disease
- Pregnancy
- Limited or poor support systems
A history of prior withdrawals has a “kindling” effect. This describes the severity of symptoms that increase with repeated withdrawal episodes.
The exacerbation appears to be connected to electrical and chemical brain imbalances. This can increase your risk of severe withdrawal symptoms, even when the process begins with mild symptoms.
0-24 Hours
During this first phase, you may experience early autonomic signs of withdrawal that include tremors, anxiety, sweating, tachycardia or increased pulse, hypertension or increased blood pressure, insomnia and GI upset.
You may also experience visual or auditory hallucinations, also referred to as alcoholic hallucinosis. In these situations, you may see, hear or feel things that are not really going on.
However, you are typically alert to person, place and time and can still maintain coherent conversations. Close observation during this phase is imperative to monitor for changes and early intervention.
The risk of dehydration is heightened because of GI symptoms like nausea, vomiting and diarrhea. During this time, you may require intravenous fluid and support, including thiamine supplementation to prevent the development of neuropsychiatric disorders.
24-48 Hours
During this phase, you continue to experience persistent autonomic hyperactivity, including agitation and sleep disruption.
The risk of seizure activity is the greatest during this period and is even greater when you have a history of seizure activity or delirium tremens.
Healthcare professionals should closely monitor you for changes in levels of consciousness and vital signs and prescribe appropriate interventions as needed.
For safety, you should have reliable support people to assist with symptom management, monitoring for complications and assessing the need for urgent or emergency care.
48-72 Hours
During this phase, you are at the greatest risk of developing delirium tremens (DT).
These potentially life threatening symptoms include disorientation, severe agitation, unstable vital signs, nausea and vomiting, tachycardia or elevated pulse, hyperthermia or elevated body temperature and diaphoresis or severe sweating.
These symptoms can be severe and you should be evaluated by medical professionals as soon as possible. Early intervention can mean the difference between life and death.
Days 4-7
During this phase, most of the acute symptoms start to improve. However, you may have continued insomnia, residual anxiety and tremors. You should continue to have close supervision.
You continue to be at risk of rebound high blood pressure, irregular heartbeat, dehydration and changes in safety and support needs. As these symptoms stabilize, you can move into alcohol use disorder treatment.
Protracted Symptoms (Weeks+)
Alcohol withdrawal symptoms can extend well beyond the initial acute phase, sometimes lasting for weeks.
Typically, the symptoms include fragmented sleep, vivid dreams, irritability, “brain fog” or increased cravings. You should seek medical attention if any new symptoms develop, especially increased symptoms of depression, anxiety or suicidal ideation.
It is important to remember that the withdrawal process isn’t linear. Symptoms may resolve and reappear, like difficulty with sleep. If these become a problem, you should work with your medical provider for clinical interventions to help you through this time.
Alcohol Withdrawal Timeline FAQs
Typically, most symptoms improve or resolve in 2-5 days. However, some symptoms, such as sleep disturbances and mood changes, can persist for weeks or more.
The exact alcohol withdrawal timeline differs from person to person and can be impacted by factors including severity of use, co-occurring mental health or medical conditions and history of complicated withdrawals.
You typically begin to see withdrawal symptoms within 6-12 hours after your last drink. However, in some cases, it may be up to 24 hours.
These symptoms may present earlier and more severely when you have a history of recent heavy usage of alcohol, prior withdrawal and limited food or fluid intake.
You are at greatest risk of developing seizure activity during alcohol withdrawal between 24-48 hours after your last drink.
The risk of developing delirium tremens is typically highest during the 48-72 hours after last consumption. If you experience confusion, seizure activity, high fever, chest pain or unstable vital signs, seek emergency care as soon as possible.
Next Steps: Assessment, Care & Recovery
Alcohol withdrawal can be an uncomfortable and a possible life threatening situation. For this reason, medical professionals recommend medically supported or supervised detox. During this time, you receive close medical supervision and intervention when needed.
Assessment & Monitoring (CIWA-Ar)
Medical professionals use a serial scoring guide called the Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) to assess the severity of alcohol withdrawal symptoms.
This tool helps providers determine how to treat the symptoms and monitor for changes in your condition, including medication titration. It also helps to gauge when you are ready to take the next step on your recovery journey.
Another monitoring tool clinical staff use is vital sign checks. This includes checking blood pressure, temperature, respirations and pulse. Closely monitoring for changes can help medical professionals determine when intervention is needed and whether it is effective.
Treatment & Recovery Pathways
Your withdrawal management may include medications such as benzodiazepines to control alcohol withdrawal symptoms. Additionally, administration of intravenous fluids and supplements such as thiamine can help to normalize bodily functions and prevent complications such as dehydration and malnutrition.
In some cases, medications such as naltrexone, acamprosate or disulfiram can support ongoing recovery by reducing cravings and helping maintain abstinence after detox.
Medication assisted treatment can be extremely beneficial to support long term recovery when it’s used alongside integrated therapies such as cognitive behavioral therapy (CBT), Motivational Enhancement Therapy (MET) or contingency management (CM).
Care Settings & Safety
Medical professionals recommend medically supervised alcohol detox as the safest way to withdraw from alcohol abuse. This is especially important when you have moderate to severe addiction, have a history of relapse, comorbidities, pregnancy or when you lack a strong support system.
When you have a low risk of complications during alcohol withdrawal you may consider withdrawing without close medication support. Low-risk factors include having a mild addiction, good overall health, not being pregnant and having a strong support system.
However, alcohol withdrawal should never be attempted alone. A support person or persons, especially in the earliest phases of withdrawal, are essential and you should have a plan to seek emergency care if complications arise.
