Alcohol withdrawal refers to a condition that may occur when an individual with alcohol use disorder suddenly stops or significantly reduces their alcohol consumption. A person may notice initial symptoms after a few hours that could last for up to a week or longer.
Individuals with alcohol withdrawal syndrome may experience nausea, anxiety, extreme fatigue, and even seizures and hallucinations. These symptoms occur as a person’s body adjusts to the absence of alcohol in their system. And while symptoms typically improve within 5 days, some individuals may experience prolonged symptoms.

Symptoms of alcohol withdrawal can occur as early as a few hours after a person’s last drink. For some, these symptoms may peak within the first 24–48 hours after alcohol cessation, but they may continue after this point in others. And while symptoms generally improve within 5 days, some may experience prolonged symptoms.

Minor withdrawal symptoms: 6–12 hours
Minor symptoms will start approximately 6–12 hours after the last drink. Symptoms can include tremors, excessive sweating, nausea and vomiting, hypertension, elevated heart rate, elevated body temperature, and rapid breathing.
Alcoholic hallucinosis: 12–24 hours
Some individuals may start experiencing hallucinations. They might start seeing and hearing things that are not there and experience sensations, such as pins and needles. While this is unusual, experts do not consider them severe.
Alcohol withdrawal seizures: 24–48 hours
At 24–48 hours after their last drink, some individuals may start experiencing seizures and some milder symptoms. If they are not already at the hospital, it is advisable to seek immediate medical attention.

This is where symptoms are usually the most severe, with some individuals displaying delirium tremens — hyperactive autonomic activity that can lead to cardiac collapse. Delirium tremens can last up to 5 days, with a mortality rate of up to
Currently, health experts do not know if any factors influence the timeline of alcohol withdrawal syndrome aside from how much alcohol an individual typically consumes. More studies are necessary to better understand this condition and how certain factors may affect the timeline and severity of symptoms.
Some evidence suggests the following factors can affect the severity and duration of symptoms:
- frequency of drinking
- the amount they consume during drinking
- length of time drinking
- medical history
- co-occurring health conditions
- if they have other substance use disorders
Individuals experiencing mild symptoms could receive home treatment with the help of close friends and family members. However, if symptoms worsen, it is advisable to seek immediate medical attention so that individuals receive appropriate treatment.
A doctor can perform a typical checkup and a blood test to see if the individual is still in good health or needs a treatment plan or medication. Others experiencing more severe symptoms may require hospitalization to avoid life threatening conditions. A doctor may also need to administer fluids intravenously to prevent dehydration and correct electrolyte abnormalities. They may also need to give medications to help reduce the severity of the symptoms.
Most treatment options may include the administration of long-acting benzodiazepines. A common benzodiazepine that a doctor may prescribe includes diazepam. During initial treatment, a person may receive a higher dosage of benzodiazepines to reduce symptoms and the urge to drink alcohol. After symptoms subside, a doctor will taper the dose until they determine the individual no longer requires medication.
Some of the alcohol withdrawal symptoms that benzodiazepines can help prevent and treat include:
- headaches
- nausea and vomiting
- insomnia
- aggravation and irritability
- chills and sweats
- seizures
Research also notes that an intravenous administration of benzodiazepines can help
In addition to benzodiazepines, a person may also require other medications,
Many people experiencing symptoms associated with alcohol withdrawal syndrome will likely recover with suitable treatment. However, it is important for individuals to receive medical attention if symptoms are severe or worsen over time.
Some symptoms, such as irritability, fatigue, and sleep disturbances, may persist over time while the body adjusts to the lack of alcohol. Individuals may also want to consider maintenance medications, a support group, or enlisting the support of friends.
Alcohol withdrawal syndrome is a condition that occurs when an individual stops consuming alcohol after a long-term dependence. Symptoms that have associations with this condition can be mild, severe, or in some cases, life threatening.
Symptoms usually begin within 6–12 hours of the last drink and can last for a few days. For most people, symptoms will typically improve within 5 days. Individuals experiencing severe symptoms may require immediate treatment at the hospital treatment to minimize the risk of potential complications.
