Alcohol withdrawal symptoms and delirium tremens: when it becomes life-threatening

What are alcohol withdrawal symptoms, and when do they start?

Alcohol withdrawal symptoms are what happens to the body and mind when someone who has been drinking heavily for a long time stops, or suddenly cuts down. They usually begin within hours of the last drink and include shaking, sweating, anxiety, sleeplessness, nausea and a racing heart. For many people these symptoms pass safely, but for some they progress to seizures or delirium tremens, conditions that can threaten life.

The reason is that alcohol slows the brain down, so the brain adapts to its constant presence by revving itself up to compensate. When the alcohol suddenly disappears, the brain is left "racing" with no brake, and the symptoms appear. Cleveland Clinic (2024) says that about half of people with alcohol use disorder who stop or sharply cut down their drinking go through withdrawal symptoms.

If you are reading this because someone in your family has decided to stop drinking, that is a brave step that deserves support. This article is here to help that step happen safely.

The usual order of alcohol withdrawal symptoms

Timing varies from person to person, and not everyone goes through every stage. But medical sources such as MedlinePlus, Cleveland Clinic and the UK's National Health Service (NHS) describe a rough general order:

1. In the first hours (roughly 6 to 12 hours): headache, anxiety and tension, sleeplessness, nausea, sweating and shaking hands, which families often notice as "the shakes" after someone stops drinking.
2. During the first day: the shaking and fast heartbeat may get worse, and some people may see or hear things that are not there (hallucinations), depending on how severe the withdrawal is, as Cleveland Clinic notes.
3. Between the first and third day: symptoms peak for most people and then start to settle. This is also when the risk of seizures is higher.
4. Roughly between the second and fourth day: delirium tremens may appear in some people, and it can occasionally be delayed until 7 to 10 days after the last drink, as MedlinePlus notes.
5. After that: sleep problems, mood swings and tiredness can continue for weeks or months; this is expected and improves with treatment and time.

It is important to know that how severe a withdrawal will be is hard to predict at the start, which is why Cleveland Clinic advises getting medical help even when symptoms are mild.

Alcohol withdrawal seizures and delirium tremens: why are they emergencies?

Withdrawal seizures

Alcohol withdrawal seizures usually happen within the first three days after the last drink, and can start as early as about 12 hours, according to MedlinePlus. They are usually seizures that involve the whole body with loss of consciousness, and they can lead to falls and injury. A review published in American Family Physician in 2013 notes that up to a third of people who have a seizure during withdrawal may go on to develop delirium tremens, so a seizure is never something to brush off, even if it stops quickly.

If someone has a seizure in front of you, call an ambulance on 123 or your local emergency number, then do what the NHS advises until the paramedics arrive:

• Do not put anything in their mouth, not even your fingers.
• Do not move them unless they are in danger; put something soft under their head if they are on the ground, and loosen anything tight around their neck.
• Once the seizure stops, turn them onto their side, stay with them and talk to them calmly until they come round.
• Note the time the seizure starts and ends so you can tell the medical team, and give them no food or drink until they have fully recovered.

Delirium tremens

Delirium tremens is the most severe form of alcohol withdrawal, and MedlinePlus describes it as a medical emergency. It brings a sudden, severe change in awareness and in the nervous system. Its signs include:

• Sudden, severe confusion: the person doesn't know where they are or what day it is, and sometimes doesn't recognize their own family.
• Hallucinations: seeing or hearing things that aren't there and reacting to them as if they were real, with intense fear or agitation.
• Shaking of the body, sweating and a raised temperature.
• Agitation and restlessness, or the opposite: extreme drowsiness and a deep sleep that can last a day or longer.
• Increased sensitivity to light, sound or touch, and rapid mood changes.

Cleveland Clinic (2024) states that about 5% to 10% of people who develop delirium tremens die from it. Complications listed by MedlinePlus include a disturbance of the heart rhythm that can be life-threatening, injury from falls during a seizure, and harm to themselves or others because of the confusion. That is why delirium tremens needs treatment in hospital, where the medical team monitors vital signs, fluids and the body's salts (electrolytes) and gives the right treatment.

Who is most at risk of a severe withdrawal?

No one can know for certain in advance how a withdrawal will go, but medical sources identify factors that raise the risk, including:

• A previous history of delirium tremens or withdrawal seizures.
• Heavy daily drinking for several months or more, or drinking for more than ten years, as MedlinePlus notes.
• Stopping after heavy drinking while eating too little, or with poor nutrition.
• Other illnesses, such as abnormal liver function, an infection or a head injury.
• Dehydration and imbalances in the body's salts (electrolytes).
• Older age: Cleveland Clinic notes that people over 65 are at higher risk.

MedlinePlus notes that delirium tremens is more common in people who have been through alcohol withdrawal before. So don't rely on "it went fine last time". Also tell the doctor about any other medicines or substances the person takes alongside alcohol, because that changes the treatment plan.

Is alcohol withdrawal dangerous? Why medically supervised detox is the safe route

The NHS warns that stopping drinking suddenly can be very dangerous for someone who has become dependent on alcohol, and advises getting medical help before trying to stop. The point is not to keep drinking, but to stop with a medical plan that protects you.

The 2013 American Family Physician review explains that people with a history of withdrawal seizures or delirium tremens, severe symptoms, unstable mental or physical illnesses, or no one to look after them at home need treatment in a medical facility. For a detailed comparison, read about home detox vs a treatment center.

Alcohol withdrawal treatment: what happens during supervised detox?

Treatment starts with a medical assessment of the person's drinking history, general health, other illnesses and any other substances, and then the doctor puts together a plan that fits them. Care usually includes:

• Continuous monitoring of blood pressure, temperature and pulse, with blood tests and electrolyte checks, as MedlinePlus describes, to catch any deterioration early.
• Medicines decided by the doctor to ease symptoms and prevent seizures and delirium, such as medicines from the benzodiazepine class, which are given and then reduced on a schedule the doctor sets, under monitoring.
• Vitamins, most importantly vitamin B1 (thiamine), because a lack of it is common in people who drink heavily and can cause a serious brain condition called Wernicke encephalopathy, which shows up as confusion and problems with walking and vision, as MedlinePlus explains.
• Fluids and nutrition, and correcting dehydration and electrolyte imbalances.
• Mental health assessment and care, because anxiety and depression often come with withdrawal, and some people may need follow-up for thoughts of self-harm.

At Oxygen Center, inpatient detox at the center is for males aged 15 and over (under 18 with a guardian's consent), with round-the-clock medical follow-up, after a medical assessment decides whether a stay at the center suits the case. Anyone showing emergency signs such as a seizure or delirium tremens needs an ambulance and a hospital first. Outpatient doctor appointments are available to both men and women, and families can come on their own first to ask questions and understand the steps.

What comes after alcohol detox? Rehabilitation and relapse prevention

The end of the physical symptoms does not mean the end of treatment. As the 2013 American Family Physician review puts it, successfully treating withdrawal is the first step toward long-term abstinence from alcohol. After that comes longer-term treatment, which, as the NHS and MedlinePlus describe, includes:

• Psychotherapy sessions, such as cognitive behavioral therapy (CBT), to understand what drives the drinking and learn new ways of coping with stress, alongside support groups.
• Medicines a doctor may decide on after stopping to reduce cravings, such as naltrexone or acamprosate.
• A clear relapse-prevention plan: knowing the situations that trigger cravings, avoiding them, and building supportive activities and relationships.
• Support and guidance for the family, because relatives also need support and need to know how to help.

When should you get help?

• Now, straight away (ambulance 123 or your local emergency number): if there is a seizure, severe confusion, hallucinations, a high temperature, a clearly abnormal heartbeat, loss of consciousness, or confusion together with unsteady walking or problems with eye movements or vision (which can be a sign of Wernicke encephalopathy).
• Quickly, without waiting (a doctor or the nearest emergency department): if shaking, sweating, sleeplessness and anxiety appear after stopping, even mild ones, especially after recent heavy drinking or if the person has had a difficult withdrawal before, as MedlinePlus advises.
• Before stopping: if the person drinks daily or heavily and plans to stop, it is best to start with a doctor's appointment to work out the safe way to do it.
• If thoughts of self-harm or suicide appear: if the person is in danger now or cannot keep themselves safe, call an ambulance on 123 straight away or go to the nearest emergency department, and don't leave them alone. If there is no immediate danger, you can also get support from the Ministry of Health's 24/7 mental-health hotline on 16328 or Oxygen Center's 24/7 emergencies line on +20 100 006 6752; these lines are extra support, not a replacement for the ambulance.

In Egypt, the Fund for Drug Control and Treatment of Addiction runs a hotline on 16023 for confidential treatment through its partner centers. You can also reach Oxygen Center on +20 101 687 0711 (calls and WhatsApp) or +20 45 320 0011. Remember that stopping alcohol safely is possible, and asking for help early is the best thing you can do for yourself or for someone you love.
