In brief
- Delirium tremens (alcohol withdrawal delirium) is an acute disturbance of consciousness that develops when alcohol is stopped after prolonged heavy drinking.
- It usually begins 2–4 days after stopping or sharply reducing use, more often at night.
- Key signs: confusion, disorientation, vivid hallucinations, severe tremor, sweating, insomnia, tachycardia, high anxiety and agitation.
- It is an emergency: without treatment, seizures, arrhythmia, brain swelling and death are possible. It cannot be treated at home.
- Do not try to «wait it out», do not give alcohol or random sedatives — medical supervision is needed.
- At Demeevka you can urgently get a consultation and a doctor's visit in Kyiv around the clock.
Delirium tremens is life-threatening. Call emergency medical help if at least one of these is present:
- seizures, loss of consciousness, or the person does not respond;
- aggression, attempts to flee, or behaviour dangerous to themselves or others;
- high fever, breathing problems, chest pain or arrhythmia;
- marked dehydration, repeated vomiting, a sharp worsening of the condition.
What delirium tremens is and when it starts
Delirium tremens is alcohol withdrawal delirium, the most severe form of the withdrawal syndrome. It is caused not by intoxication itself but, on the contrary, by a sharp drop in blood alcohol after a prolonged binge. The nervous system, used to the constant effect of alcohol, becomes overexcited, and this leads to a disturbance of consciousness.
The typical onset window is 2–4 days after the last dose, sometimes earlier. The warning signs are insomnia, rising anxiety, hand tremor, sweating and nightmares. The longer the binge and the more co-existing illnesses, the higher the risk of a severe course.
Symptoms the family notices
Delirium affects consciousness, the mind and the body at once. The most noticeable groups of signs are:
The person does not understand where they are or what day it is, does not recognise loved ones, speech becomes incoherent.
Vivid visual images, voices, a sensation of insects on the skin, delusions of persecution and fear.
Strong shaking of the hands and body, heavy sweating, nausea, vomiting, high fever.
A racing heart, blood-pressure swings, shortness of breath — the strain on the heart is dangerous.
Marked restlessness, aggression or fear, a complete lack of sleep for several days in a row.
How long it lasts and why it is dangerous
The duration depends on the person's condition and how promptly help is given. The approximate course:
2–4 days after the dose drops, anxiety, insomnia, tremor and sweating appear.
Confusion, hallucinations, agitation and autonomic disturbances; symptoms are worse at night.
Without treatment, seizures, arrhythmia, pneumonia and brain swelling are possible.
Under supervision the acute period passes faster and complications are managed.
First aid: what to do and what not to do
Before the doctor arrives, the main thing is the safety of the person and those around them.
Do not leave the person alone, remove dangerous objects, ensure calm, water and fresh air.
With seizures, aggression, impaired consciousness or breathing — emergency medical help; otherwise an urgent addiction-doctor visit.
Do not give «a drink to recover», sleeping pills, sedatives or drips without a doctor's prescription.
Do not try to convince or irritate a person in psychosis; speak briefly and calmly and do not use force.
Why a hospital is needed
Delirium tremens is treated only under medical supervision. In the hospital, detox is carried out, the water-salt balance is restored, the heart and nervous system are supported, and the condition is monitored around the clock. This lowers the risk of complications and death.
After the acute state is relieved, it is important not to stop: treatment of the alcohol dependence, psychotherapy and family support are needed, otherwise the risk of recurrence is high.
