Alcohol Withdrawal and Delirium Tremens Case Study: Patient Background
This alcohol withdrawal and delirium tremens case study follows Suresh (name changed), a composite example that reflects how severe alcohol withdrawal commonly develops and how it is treated in hospital and at Calida Rehab. The details are illustrative and do not describe any one identifiable person.
Suresh is a 46-year-old businessman from Thane. He runs a building-material supply business and lives with his wife and two children in a flat in Majiwada. He had his first drinks at business dinners in his twenties. Over the years, weekend drinks became a nightly habit. For about eight years he had been drinking whisky every evening, usually eight to ten drinks, and sometimes he started earlier in the day to steady his nerves. Twice before, when he missed a day, he had felt shaky and sweaty, and both times a drink made the feeling go away. After a routine health check showed raised liver enzymes and a fatty liver, his family urged him to stop. He decided to quit on his own, at home, on a Monday night, without telling a doctor. By Tuesday morning his hands were shaking, his heart was racing and he could not sleep. Early on Wednesday, about thirty hours after his last drink, he had a seizure. His wife called an ambulance, and over the next two days in hospital he developed delirium tremens. Once he was medically stable, the hospital team referred him to Calida Rehab for further care.
Before the case itself, a short note. Alcohol withdrawal is the group of symptoms that appear when a person who has been drinking heavily for a long time suddenly stops or sharply cuts down. It can be mild, with shakiness and poor sleep, or severe, with seizures. Delirium tremens, often called DT, is the most serious form. It brings sudden confusion, hallucinations, fever, a racing heartbeat and severe agitation, and it is a medical emergency. Not everyone who stops drinking develops it, and no one can predict in advance who will. For more, read our guide to alcohol withdrawal symptoms, our article on the stages of alcoholism and delirium tremens and our page on alcohol addiction treatment.
Symptoms: How Alcohol Withdrawal and Delirium Tremens Showed Up
Alcohol withdrawal can range from mild to life-threatening, and it can get worse within hours. The signs below are grouped by how serious they are and roughly when they appear after the last drink.
Mild to moderate withdrawal (usually 6 to 12 hours after the last drink)
- Shaking hands or a tremor
- Sweating and a racing heartbeat
- Anxiety, restlessness and irritability
- Nausea, vomiting and loss of appetite
- Headache
- Difficulty sleeping
Serious withdrawal (often 12 to 48 hours after the last drink)
- Seizures, which can happen without warning
- Hallucinations while still fully aware, such as seeing or hearing things that are not there
- Severe tremor, repeated vomiting and rising blood pressure
Delirium tremens (usually 2 to 4 days after the last drink)
- Confusion, and not knowing the time, the place or the people around
- Vivid hallucinations, often of insects, animals or people
- High fever and heavy sweating
- A very fast heartbeat and high blood pressure
- Extreme agitation, fear or suspicion
- Days without sleep
- Dehydration and dangerous changes in the body’s salts, which can be fatal if untreated
In this case: Suresh’s tremor, sweating and anxiety began within hours of his last drink, and by Tuesday night he had not slept at all. At about thirty hours he had a generalised seizure at home and was taken to hospital. By Thursday he was confused and did not know which hospital he was in. He saw insects crawling on the walls and the bedsheet, believed strangers were in the room, and became so agitated that he pulled out his drip. He had a fever of 38.6 degrees Celsius and a pulse above 120. He remembers almost nothing from those two days, which is common after delirium tremens.
A doctor grades withdrawal by how severe the symptoms are and how long ago the last drink was. A person with a seizure, hallucinations or confusion needs hospital care straight away.
Why Alcohol Withdrawal Is Often Underestimated
Many people, and many families, think that stopping alcohol is only a matter of willpower. In fact, alcohol is one of the few substances where suddenly stopping after heavy, long-term use can be life-threatening. The shakes and sweats are often put down to weakness or a hangover, and a person may drink again to make them go away, which keeps the cycle going. That is why withdrawal is so often underestimated.
Some people are at higher risk of severe withdrawal. These include people who have drunk heavily every day for years, those who have had seizures or delirium tremens in an earlier withdrawal, older adults, and people with liver disease, infections or other illnesses. Low levels of potassium or magnesium add to the risk. Each episode of withdrawal can also make the next one worse, which is why repeated unsupervised attempts to stop are risky.
In this case: Suresh had felt mild shakiness before when he missed a drink, but he saw it as a bad hangover. His family wanted him to stop, and he believed that quitting at home on his own was the strong and honest way to do it. Nobody had told him that after eight years of daily drinking, stopping suddenly without medical help could be dangerous. The seizure was the first real alarm.
Diagnosis: How Alcohol Withdrawal and Delirium Tremens Were Assessed
Withdrawal is diagnosed by a doctor through a careful history and examination, and severe withdrawal is treated first. Suresh’s first assessment took place in the hospital emergency department. After he was stable, the Calida Rehab team repeated and extended it. A full assessment typically includes:
- A detailed drinking history, including how much and how often the person drinks, the time of the last drink, and any earlier withdrawal, seizures or DT
- The CIWA-Ar scale, the Clinical Institute Withdrawal Assessment for Alcohol, which scores tremor, sweating, anxiety, agitation, nausea, hallucinations and orientation to guide how much treatment is needed
- Vital signs, including pulse, blood pressure, temperature and oxygen level, checked repeatedly
- Blood tests, such as liver function tests (SGOT, SGPT, GGT), blood sugar, sodium, potassium, magnesium, kidney function and a complete blood count
- An ECG to look for heart rhythm problems
- A brain scan or EEG when a seizure needs further investigation
- The AUDIT questionnaire, the Alcohol Use Disorders Identification Test developed by the World Health Organization, once the person is clear-headed
- Screening for other substances and for mental health conditions such as anxiety and depression
- Input from a family member, with the person’s consent
The doctor also decides whether the symptoms are due to withdrawal or to something else, such as infection, head injury, low blood sugar or liver failure, because these can look similar and may occur together. You can read more about the long-term effects of heavy drinking on our page on alcohol dependence syndrome.
Result in this case: Suresh was diagnosed with severe alcohol use disorder, with a withdrawal seizure and alcohol withdrawal delirium (delirium tremens). His AUDIT score was 33. His tests showed raised liver enzymes with a fatty liver, and low potassium and magnesium. A scan after the seizure showed no head injury. He had no other substance use, but he had mild anxiety and poor sleep. For the first time he understood that the way he had stopped drinking had put his life at risk, and that he needed proper treatment.
Treatment Plan for Alcohol Withdrawal and Delirium Tremens
Treatment of severe withdrawal has two parts: first making the person medically safe, and then treating the alcohol use disorder itself. Suresh’s care followed both.
Emergency hospital treatment. Delirium tremens is treated in a hospital, often in an intensive care or high-dependency unit. Benzodiazepine medicines, such as diazepam or lorazepam, are the main treatment. They calm the overactive nervous system and lower the risk of further seizures. The dose is guided by withdrawal scores and given only under close supervision, and the course lasts days, not weeks. Used this way, in a hospital and for a short period, they are very different from long-term unsupervised use, which you can read about in our benzodiazepine addiction case study.
Thiamine and fluids. Thiamine (vitamin B1) is given early, before any glucose drip, to protect the brain from a serious condition called Wernicke encephalopathy. Fluids, potassium and magnesium are replaced, and blood sugar is monitored.
Monitoring and a calm environment. Pulse, blood pressure, temperature and oxygen level are checked often. A quiet, well-lit room with a calm, familiar person nearby helps reduce fear and confusion. For severe hallucinations or agitation, the treating doctor may add a second medicine.
Treatment after stabilisation. Once Suresh was stable, he was admitted to Calida Rehab for further care. The team recommended a structured residential programme of about four weeks, followed by outpatient care, because he had a severe disorder and a history of dangerous withdrawal. Read more on our detoxification page.
Medicine to reduce craving. Because his liver enzymes were still raised, the psychiatrist chose acamprosate, which is not broken down by the liver, instead of naltrexone. Medicines work best alongside therapy, not instead of it.
Treatment of other health problems. His fatty liver, vitamin levels, sleep and anxiety were treated or monitored alongside the drinking.
Family involvement. His wife joined family sessions to learn about withdrawal, why he must never stop suddenly again, and how to respond to cravings or a slip. She was also taught which warning signs mean an emergency.
Lifestyle. Fixed meal and sleep times, light exercise and planned free time fill the space that drinking leaves behind.

Therapies Used in This Alcohol Withdrawal Case Study
The therapies below were part of Suresh’s plan and are commonly used for alcohol use disorder.
- Motivational Enhancement Therapy (MET): helps the person explore mixed feelings about drinking and build their own reasons to stay sober, especially after a frightening medical event. See our motivational interviewing page.
- Cognitive Behavioral Therapy (CBT): identifies triggers such as business dinners, stress and the evening routine, and teaches skills to handle cravings and negative thoughts. Read more on our CBT page.
- Relapse prevention planning: a written plan for high-risk situations, early warning signs and what to do after a slip, including the rule that any future attempt to stop must be supervised by a doctor. See our relapse prevention therapy page.
- Psychoeducation on withdrawal: clear information for the person and the family about what happens in the body when alcohol is stopped and why it can be dangerous
- Individual counselling: one-to-one sessions to work through guilt, fear and the pressures behind the drinking. See our individual counselling page.
- Family therapy: sessions that help families communicate, set healthy limits and rebuild trust. See our family therapy page.
Follow-Up Care After the First Phase
Alcohol use disorder is a long-term condition, so care does not end when the first phase of treatment ends. For a person who has had withdrawal seizures or delirium tremens, follow-up usually includes:
- Regular counselling sessions, with more frequent sessions in the first months and wider gaps later
- Repeat blood tests, including liver function, potassium and magnesium, usually around three months
- Review of sleep, mood and anxiety, with treatment adjusted if needed
- Continued craving medicine for as long as the psychiatrist advises
- A plan for known triggers such as business dinners, festivals and weekends
- A clear emergency plan: if drinking restarts and then needs to stop, it must be done under medical supervision, never alone at home
- Booster sessions to refresh relapse-prevention skills when cravings or triggers return
- Continued involvement of the family, where the person agrees
A slip does not mean treatment has failed. It is a signal to get support quickly. Read our guide on relapse in addiction recovery, and see our alcohol addiction treatment page to understand what ongoing care looks like.
Outcome: What Recovery Looks Like After Delirium Tremens
What changed for Suresh over the first three months:
- Drinking: he stopped drinking. At a cousin’s wedding he felt a strong craving, stepped outside and called his counsellor, and he did not drink.
- Body and mind: his confusion cleared within days of stabilisation. His tremor settled and he was sleeping through the night by the third week. He has had no further seizures.
- Health: at the three-month review his liver enzymes, potassium and magnesium had improved.
- Work: he returned to work after about five weeks. He now leaves the office at a fixed time and no longer joins late-night supplier dinners.
- Family: trust returned slowly. His wife said the hospital days had frightened the whole family, and that she was glad to see him calm in the evenings.
- Time and money: he started morning walks with his son and put the money he once spent on drinks towards a family trip.
It is worth being clear about what recovery means. It is not only a stretch without alcohol. It is a person who understands why stopping suddenly was dangerous, who knows his triggers, and who knows what to do and whom to call when a hard phase returns.
What the first six months of treatment usually look like
- Weeks 1 to 2: emergency or medically supervised withdrawal care, then stabilisation.
- Weeks 3 to 6: a structured residential programme with therapy, family sessions and a written plan.
- Months 2 and 3: therapy skills build. Blood tests, sleep and mood are reviewed.
- Months 4 to 6: gains settle in. The team reviews what is working and what still needs support.
This is a general guide. Every person moves at a different pace.
Key Takeaways from This Alcohol Withdrawal Case Study
- Stopping alcohol suddenly after heavy, long-term drinking can be dangerous and should be done with medical supervision.
- Seizures, confusion, hallucinations, fever and a racing heartbeat after stopping drinking are signs of severe withdrawal and need emergency care.
- Delirium tremens is a medical emergency, but it is treatable when it is recognised early.
- A past seizure or DT raises the risk next time, so a person with this history should never stop alone at home.
- After the emergency, therapy, craving medicine and family support are what protect long-term recovery.
- Wanting to stop is a strong first step. Doing it safely is what protects life.
When Should You See a Doctor?
Please speak to a doctor before stopping, or if you or someone you know:
- Drinks every day and wants to stop or cut down
- Gets shaky, sweaty, anxious or unable to sleep when a drink is missed
- Drinks in the morning to steady the nerves or to feel normal
- Has had a seizure, confusion or hallucinations when stopping alcohol before
- Has liver disease, heart disease, diabetes or another long-term illness and drinks heavily
- Is seeing health, work, money or relationships suffer because of drinking
Delirium tremens and withdrawal seizures are emergencies. Call 112 or go to the nearest hospital at once if a person who has stopped or cut down on alcohol has a seizure, becomes confused or does not know where they are, sees or hears things that are not there, has a high fever, a very fast heartbeat or severe shaking, or vomits repeatedly. Do not wait to see if it settles, and do not try to manage it at home. Read more in our guide on when to go to hospital in an addiction emergency.
If you or someone you know ever talks about hurting themselves, do not wait. Call 112 in an emergency, or Tele-MANAS on 14416. You can also call our 24-hour helpline for a confidential conversation.
Alcohol Withdrawal and Delirium Tremens: Frequently Asked Questions
What is alcohol withdrawal?
Alcohol withdrawal is the group of symptoms that appear when a person who has been drinking heavily for a long time suddenly stops or sharply cuts down. Symptoms range from tremor, sweating and anxiety to seizures and delirium tremens.
What is delirium tremens?
Delirium tremens, or DT, is the most severe form of alcohol withdrawal. It causes confusion, hallucinations, fever, a fast heartbeat, high blood pressure and severe agitation, usually two to four days after the last drink. It is a medical emergency and needs hospital treatment.
How soon after the last drink do withdrawal symptoms start?
Mild symptoms usually begin 6 to 12 hours after the last drink. Seizures and hallucinations can occur within 12 to 48 hours, and delirium tremens usually appears 2 to 4 days after the last drink.
Is it dangerous to stop drinking suddenly?
It can be. In people who have drunk heavily every day for a long time, stopping suddenly can cause seizures and delirium tremens, which can be fatal without treatment. Anyone who drinks heavily every day should speak to a doctor before stopping.
How is delirium tremens treated?
Treatment is given in a hospital. It usually includes benzodiazepine medicines under close supervision, thiamine, fluids, replacement of potassium and magnesium, and constant monitoring of pulse, blood pressure, temperature and oxygen level. Early treatment greatly improves the outcome.
Can delirium tremens be prevented?
In many cases, yes. Medically supervised withdrawal, with early treatment of symptoms and the right medicines, greatly lowers the risk of seizures and delirium tremens. This is why people at risk should not stop drinking alone at home.
Can I detox from alcohol at home?
Home detox is not safe for people who drink heavily every day, who have had seizures or DT before, or who have liver or other illness. A doctor can advise whether supervised care at a centre or hospital is needed.
Is treatment needed after withdrawal is over?
Yes. Withdrawal care only covers the first days. Therapy, craving medicine when advised, family support and follow-up are what help a person stay sober over the long term.
Is my information kept private?
Yes. Assessment and treatment details are confidential and are shared with family or employers only with your consent.
