Alcohol withdrawal syndrome (AWS) is a set of symptoms that can occur when someone abruptly stops drinking after prolonged and heavy alcohol use. The severity of AWS can vary from mild symptoms such as insomnia, trembling, and anxiety to severe and life-threatening symptoms such as alcoholic hallucinosis, delirium tremens, and autonomic instability. Mild symptoms typically appear within 6 to 12 hours after the last drink, while more serious symptoms can start to appear within 12 to 48 hours. Symptoms tend to peak and are at their worst between 24 to 72 hours after the last drink, with the highest risk of seizures occurring within this timeframe. Delirium tremens, a severe form of AWS, typically occurs between 48 to 72 hours after the last drink and can be fatal if untreated.

What You'll Learn
Symptoms typically peak within 24-72 hours
Alcohol withdrawal symptoms typically begin within six to 24 hours of stopping or significantly decreasing alcohol consumption. These symptoms can range from mild to severe, depending on the severity of the withdrawal. Mild symptoms include anxiety, nervousness, irritability, excessive sweating, upset stomach, and heart palpitations. More severe symptoms include hallucinations, delirium tremens, and seizures.
The severity of alcohol withdrawal symptoms typically peaks within 24 to 72 hours of the last drink and then begins to resolve. During this time, individuals may experience a range of physical and psychological symptoms, such as increased blood pressure, increased heart rate, hyperthermia, tremors, and jitteriness. Some people may also experience prolonged withdrawal symptoms, such as insomnia and mood changes, that can last for weeks or even months.
Delirium tremens (DTs) is the most severe form of alcohol withdrawal and is considered a medical emergency. It is characterised by profound global confusion, agitation, disorientation, hallucinations, fever, hypertension, and diaphoresis. The lifetime risk for developing DTs among individuals with chronic alcohol addiction is estimated at 5-10%, with a current mortality rate of 5-15%. However, this rate should be closer to 5% with modern ICU management.
It is important to note that the withdrawal timeline and symptoms can vary depending on individual factors, such as the amount and frequency of alcohol consumption, the presence of other medical problems, and the person's overall health. Seeking medical attention and support during alcohol withdrawal is crucial, especially for severe or complicated cases, as it can be a life-threatening condition.
Withdrawal management and treatment options may include a calm, quiet, and well-lit environment, reassurance, ongoing reassessment, addressing fluid and electrolyte deficits, and treating any coexisting addictions. Additionally, total and lifelong avoidance of alcohol (abstinence) is recommended for individuals experiencing alcohol withdrawal to prevent relapse and ensure long-term recovery.

Mild symptoms include headaches, anxiety and insomnia
Mild alcohol withdrawal symptoms can begin as soon as six to eight hours after the last drink. These initial symptoms include headaches, mild anxiety, and insomnia. However, the severity of these symptoms can vary depending on the individual and the severity of their alcohol use disorder (AUD). AUD is the most common substance use disorder in the US, affecting 28.8 million adults.
Headaches, anxiety, and insomnia are just a few of the mild symptoms associated with alcohol withdrawal. Other mild to moderate symptoms include nervousness, irritability, excessive sweating, an upset stomach, heart palpitations, increased blood pressure, and tremors. These symptoms typically peak within 24 to 72 hours after the last drink and can often be treated in an outpatient setting. However, it is important to have someone to support you and monitor these symptoms, as they can sometimes lead to more severe complications.
Anxiety, specifically, can manifest as jitteriness and nervousness. This is due to the changes in neurotransmitters in the brain, particularly the imbalance between GABA (gamma-aminobutyric acid) and glutamate. When consuming alcohol, the brain produces more GABA, which induces feelings of relaxation and euphoria, and less glutamate, which is associated with excitability. When a person abruptly stops drinking, the brain struggles to keep up with this sudden change, resulting in withdrawal symptoms.
While mild symptoms can occur within the first 24 hours, more severe symptoms can develop if alcohol withdrawal is not properly managed. Delirium tremens (DTs), also known as alcohol withdrawal delirium (AWD), is the most severe form of alcohol withdrawal. It is considered a medical emergency with a high mortality rate, and symptoms include profound global confusion, agitation, disorientation, hallucinations, fever, hypertension, and autonomic hyperactivity. DTs can occur 48 to 72 hours after the last drink, and it is important to seek immediate medical attention if these symptoms arise.
It is crucial to note that alcohol withdrawal can be a dangerous process, and total abstinence from alcohol is the safest approach to prevent severe health complications. If you or someone you know is experiencing alcohol withdrawal symptoms, it is important to seek medical advice and support to ensure a safe and effective recovery process.

Severe symptoms include seizures and hallucinations
Alcohol withdrawal syndrome (AWS) occurs when a person abruptly stops drinking after prolonged alcohol use. Symptoms of AWS can range from mild to severe, with the most severe being life-threatening. The severity of AWS is commonly classified into three stages. Mild symptoms typically appear within 6 to 12 hours after the last drink and include headache, mild anxiety, insomnia, nervousness, irritability, upset stomach, heart palpitations, and increased blood pressure.
Within 24 hours of the last drink, more severe symptoms may occur, including hallucinations. Hallucinations are a common symptom of alcohol withdrawal and can be visual, auditory, or tactile. They can be extremely disturbing and cause a great deal of distress to the person experiencing them. It is important to monitor the person closely and provide a calm, quiet, and well-lit environment to help reduce the intensity of the hallucinations.
The risk of seizures is highest between 24 and 48 hours after the last drink, and they can be life-threatening. Seizures can occur with or without hallucinations and are often preceded by other symptoms such as confusion, disorientation, and agitation. It is important to seek medical attention immediately if seizures occur, as they can lead to serious complications or even death.
Delirium tremens (DTs) is the most severe form of alcohol withdrawal and is considered a medical emergency. It typically occurs 48 to 72 hours after the last drink and is characterized by profound global confusion, agitation, disorientation, hallucinations, fever, hypertension, and autonomic hyperactivity. The current mortality rate for patients with DTs ranges from 5-15%, but with modern ICU management, this number should be closer to 5%.
In conclusion, severe symptoms of alcohol withdrawal, including seizures and hallucinations, can occur within 24 to 48 hours after the last drink. It is important to closely monitor individuals undergoing alcohol withdrawal during this critical period and seek medical attention if severe symptoms occur.

Delirium tremens is a fatal complication
Delirium tremens (DTs), also known as alcohol withdrawal delirium (AWD), is the most severe form of alcohol withdrawal. It is a medical emergency with a high mortality rate, which can be as high as 15% even with appropriate treatment. Therefore, early recognition and treatment are crucial.
Delirium tremens typically occurs 48 to 72 hours after an individual's last drink, though symptoms can vary between patients. It is characterised by profound global confusion, agitation, disorientation, hallucinations, fever, hypertension, diaphoresis, and autonomic hyperactivity (tachycardia and hypertension), which can progress to cardiovascular collapse.
The Clinical Institute Withdrawal Assessment of Alcohol Scale, Revised (CIWA-Ar) is a 5-minute assessment for monitoring withdrawal symptoms. Patients scoring less than 10 usually do not need additional medication for withdrawal. However, very-high-dose bolus benzodiazepines, with the addition of phenobarbital as needed, may be administered based on the CIWA-Ar or Richmond Agitation Sedation Scale (RASS).
Supportive treatment for delirium tremens includes providing a calm, quiet, well-lit environment, reassurance, ongoing reassessment, attention to fluid and electrolyte deficits, and treatment of any coexisting addictions. Thiamine can help prevent Wernicke encephalopathy and Korsakoff syndrome, which are disorders caused by thiamine deficiency.
Delirium tremens is a severe and potentially fatal complication of alcohol withdrawal. It is important to seek medical attention if you or someone you know is experiencing symptoms of alcohol withdrawal, as early intervention can reduce the risk of progressing to delirium tremens and improve the chances of recovery.

Alcohol withdrawal can be life-threatening
Alcohol withdrawal syndrome (AWS) occurs when a person abruptly stops drinking after prolonged alcohol use. AWS can be life-threatening, and it affects about 50% of people with alcohol use disorder (AUD) who stop or significantly decrease their alcohol intake. AUD is the most common substance use disorder in the U.S., affecting 28.8 million adults.
The severity of AWS is commonly classified into three stages, ranging from mild to severe. Mild symptoms typically begin within 6–24 hours of the last drink and include headache, mild anxiety, insomnia, nervousness, irritability, excessive sweating, an upset stomach, heart palpitations, increased blood pressure, and high body temperature.
However, AWS can progress to a severe form known as delirium tremens (DTs), which is a medical emergency with a high mortality rate. DTs are characterised by profound global confusion, agitation, disorientation, hallucinations, fever, hypertension, diaphoresis, and autonomic hyperactivity, which can lead to cardiovascular collapse. The lifetime risk for developing DTs among individuals with chronic alcohol addiction is estimated at 5–10%, with a mortality rate of 5–15%.
The risk of severe alcohol withdrawal and the development of DTs is influenced by various factors, including the amount and duration of alcohol consumption, the presence of co-occurring medical problems, and individual differences such as age, race, and sex. People who continue to drink heavily are also at risk of developing health problems such as liver, heart, and nervous system disease.
It is crucial to seek medical attention if you or someone you know is experiencing symptoms of alcohol withdrawal, especially if they have recently stopped drinking after prolonged use. Treatment options include supportive care, medication, and ongoing monitoring to prevent complications and ensure a safe recovery.
