What Is Alcohol Withdrawal
Alcohol withdrawal is the name of the set of physical and mental symptoms a person may experience after reducing or stopping their alcohol consumption. These symptoms may range from mild (such as headache) to severe (such as seizures).
Alcohol has a significant impact on the brain—it is classified as a depressant because drinking alcohol slows down the brain function and affects the chemicals in the brain (neurotransmitters). The brain adapts to the presence of alcohol, and when a person suddenly stops drinking, the brain may become overexcited, leading to withdrawal.
How Long Does It Take For Alcohol Withdrawal To Start
In most cases, people start feeling the first symptoms of alcohol withdrawal within a few hours after their last drink. On average, it takes from 6 to 12 hours to start experiencing withdrawal.
The duration of alcohol withdrawal depends on several factors—the history of alcohol use disorder, the level of alcohol dependence, and the frequency of drinking. Typically, alcohol withdrawal lasts from 4 to 5 days, yet some symptoms may persist for weeks and months, especially if a person does not stop drinking alcohol under medical supervision.

What Are the Symptoms of Alcohol Withdrawal
The symptoms of alcohol withdrawal are categorized in three groups: mild, minor symptoms, moderate symptoms, and severe symptoms
Mild Symptoms
- Agitation
- Anxiety
- Insomnia
- Headache
- Nausea
- Vomiting
Moderate Symptoms
- Confusion
- Tremors
- High blood pressure
- Increased heart rate
- Sweating
Severe Symptoms
- Seizures
- Hallucinations

What Are the Dangers of Alcohol Withdrawal
Is it dangerous to quit drinking abruptly? Without proper medical care, alcohol withdrawal may lead to serious consequences.
Dehydration
Symptoms such as vomiting, sweating, and diarrhea will quickly dehydrate the person, which will negatively affect their body. Make sure the patient drinks a lot of water and seeks medical help if dehydration is severe.
Injuries
A person going through withdrawal may feel dizzy and confused—there is a risk of falling and injury, especially if the individual starts hallucinating. It is advised to have a friend, family member, or medical professional stay with the person who is discontinuing alcohol use.
Delirium Tremens
One of the most serious complications associated with alcohol withdrawal is delirium tremens, which usually starts 2 or 3 days after the last drink. The person may experience auditory and visual hallucinations, experience intense agitation and confusion, and go into a coma. While only a small percentage of people who quit alcohol struggle with delirium tremens, this condition may be fatal.
How To Treat Alcohol Withdrawal Symptoms
There are several medications a doctor may prescribe to help the patient cope with withdrawal; however, it is not recommended to take these drugs without first consulting with a healthcare provider.
Drugs such as diazepam and lorazepam are commonly given to patients who go through alcohol withdrawal. Benzodiazepines are meant to calm the brain excitement, reduce anxiety, prevent seizures, and help the person sleep.
Vitamins
People with alcohol use disorder are often malnourished—it is difficult for the body to absorb nutrients from food when the individual drinks heavily. A doctor may give the patient thiamine, magnesium, and vitamins A, B, C, D, and E to restore their health.
In addition to medication, make sure the person has a supportive environment to quit drinking. A balanced diet, proper hydration, bed rest, and psychotherapy will be beneficial for the recovery process.
When Should You Seek Help For Alcohol Withdrawal
It is one thing to quit alcohol on your own when you occasionally feel mild withdrawal symptoms, yet in many cases, reaching out to a professional will be better for your health.
Medical Detox
Contact a clinic and talk to a doctor when you decide to reduce or stop your alcohol consumption. A healthcare provider will be able to diagnose your condition, prescribe medication, and supervise your detox.
Therapy
Once you have successfully gone through withdrawal, continue your treatment with a therapist. A mental health professional will help you understand the reasons behind alcohol abuse, teach you coping mechanisms, and equip you with the skills you need to avoid triggers and manage your addiction.
Support Groups
Surround yourself with people who understand what you are going through. Join a local or online support group—share your struggles and your progress, build friendships, and get advice from people who have succeeded in overcoming alcohol addiction.
