Quick answer
What is Alcohol dependence?
Alcohol dependence is when drinking has become difficult to control and the body and mind have come to rely on alcohol. People may find they need to drink more to get the same effect (tolerance), feel a strong urge or craving to drink, struggle to cut down despite wanting to, and experience withdrawal symptoms — such as sweating, shaking, anxiety, feeling sick or restlessness — when they have not had a drink for a while.
- How it is treated: Treatment combines support, structured psychological help and, where appropriate, medication, usually through specialist alcohol services who tailor the plan to the person and the severity of their dependence.
- Self-care: Seeking help early, building a support network through family, friends or mutual-aid groups, avoiding the people, places and routines that trigger drinking, finding alternative activities, eating well and addressing low mood, anxiety or sleep problems all support recovery alongside structured treatment — but any plan to cut down or stop heavy regular drinking should be made with professional advice.
- When to seek help: Speak to your GP or a local alcohol service if you feel your drinking is out of control, you cannot cut down, or it is harming your health, relationships or daily life — effective, confidential help is available and many people recover fully.
What it is
Alcohol dependence is when drinking has become difficult to control and the body and mind have come to rely on alcohol. People may find they need to drink more to get the same effect (tolerance), feel a strong urge or craving to drink, struggle to cut down despite wanting to, and experience withdrawal symptoms — such as sweating, shaking, anxiety, feeling sick or restlessness — when they have not had a drink for a while. Drinking may take up more and more time and continue despite causing harm to health, relationships, work or finances. It exists on a spectrum, from harmful drinking through to severe dependence, and it often goes hand in hand with low mood, anxiety or sleep problems. Importantly, dependence is not a matter of willpower or weak character — it is a recognised condition with biological roots, and effective help is available. Many people make a full recovery with the right support.
How it is treated
Treatment combines support, structured psychological help and, where appropriate, medication, usually through specialist alcohol services who tailor the plan to the person and the severity of their dependence. Psychological support — from brief structured advice to more intensive therapies and mutual-aid groups — is central, and addressing linked problems such as depression, anxiety or social difficulties is part of the picture. For people who are physically dependent, stopping drinking is managed safely with a planned, medically supervised withdrawal (detox), in the community or in hospital depending on the risk, because suddenly stopping heavy drinking can be dangerous. Several medicines have a recognised place: disulfiram, which causes an unpleasant reaction if alcohol is drunk and so acts as a deterrent; and acamprosate and naltrexone, which help people maintain abstinence and reduce cravings after stopping. Thiamine (vitamin B1) is given to prevent serious alcohol-related brain damage. Medicines are always used alongside, not instead of, psychological and social support, and treatment is reviewed over time.

Beyond medication
Lifestyle and self-care
Seeking help early, building a support network through family, friends or mutual-aid groups, avoiding the people, places and routines that trigger drinking, finding alternative activities, eating well and addressing low mood, anxiety or sleep problems all support recovery alongside structured treatment — but any plan to cut down or stop heavy regular drinking should be made with professional advice.
When to get help
When to see a doctor
Speak to your GP or a local alcohol service if you feel your drinking is out of control, you cannot cut down, or it is harming your health, relationships or daily life — effective, confidential help is available and many people recover fully. Crucially, do not suddenly stop drinking on your own if you have been drinking heavily every day: alcohol withdrawal can cause fits (seizures) and a dangerous, sometimes life-threatening condition called delirium tremens — with confusion, severe shaking, fever, sweating and seeing or hearing things that are not there. Get medical advice before stopping so withdrawal can be managed safely. Call 999 or go to A&E for a seizure, confusion, severe agitation or signs of delirium tremens, and for any thoughts of harming yourself; call 111 for urgent advice, and the Samaritans are available day or night on 116 123.
Not sure how urgent it is? It is always OK to call NHS 111 for advice, day or night.
Answers
Alcohol dependence: frequently asked questions
What medicines are used for alcohol dependence?
Several medicines have a recognised place once someone has stopped drinking, always alongside psychological and social support. Disulfiram works as a deterrent, causing an unpleasant reaction if alcohol is taken. Acamprosate and naltrexone help people maintain abstinence and reduce cravings after they have stopped. Thiamine (vitamin B1) is given to prevent serious alcohol-related brain damage. Medicines that ease withdrawal may also be used during a planned, supervised detox. A specialist alcohol service will advise which options suit your situation.
Is it dangerous to stop drinking suddenly?
If you have been drinking heavily every day, stopping suddenly on your own can be dangerous. Alcohol withdrawal can cause fits (seizures) and, in severe cases, a life-threatening condition called delirium tremens, with confusion, severe shaking, fever and hallucinations. For this reason, stopping heavy regular drinking should be planned with professional advice and may need a medically supervised withdrawal. If you want to cut down or stop, speak to your GP or an alcohol service first so it can be done safely.
Why is thiamine (vitamin B1) given for alcohol problems?
Heavy drinking can lead to a lack of thiamine (vitamin B1), partly because alcohol interferes with how the body absorbs and uses it and partly because of poor diet. A severe shortage can cause serious and potentially permanent brain damage (Wernicke's encephalopathy). Giving thiamine helps prevent this, which is why it is offered to people who are dependent on alcohol or going through withdrawal. It is a protective measure for the brain, used alongside the other parts of treatment.
Can alcohol dependence really be treated?
Yes. Alcohol dependence is a recognised condition, not a failure of willpower, and effective help is available — many people recover fully. Treatment combines support and structured psychological help with, where appropriate, a safely managed withdrawal and medicines that help people stop and stay stopped. Addressing linked issues such as low mood, anxiety or sleep problems is part of recovery. Reaching out to your GP or a local alcohol service is the first step, and that contact is confidential.
