Alcohol Withdrawal Symptoms

Key takeaway

Alcohol withdrawal can include tremor, sweating, a fast pulse, nausea, seizures, and delirium tremens. NIAAA says a sudden stop after chronic heavy drinking can be life-threatening, and that only a clinician can tell who needs medical detox. The lists below are symptoms and red flags. They are not a home plan.

You are trying to tell a miserable night from a night that can kill someone, and a list of symptoms is a poor substitute for a clinician who can see the person. NIAAA says alcohol withdrawal can be life-threatening if someone who has been drinking heavily for a long time stops suddenly, instead of cutting back gradually or stopping with medical support. If someone is seizing, cannot be woken, is severely confused, or is struggling to breathe, call 911. For a mental health crisis, call or text 988.

What "heavy" means before anyone talks about stopping

NIAAA defines heavy drinking as 4 or more drinks on any day or 8 or more per week for women, and 5 or more drinks on any day or 15 or more per week for men. That definition is a pattern of drinking. It is not, by itself, a diagnosis, and it is not a rule that every person over the line will have dangerous withdrawal.

Up to half of people with alcohol use disorder have some withdrawal symptoms when they stop. A small proportion need medical care and monitoring, which clinicians often call detox, for symptoms that can become dangerous. NIAAA also reports that alcohol withdrawal accounts for about 260,000 emergency department visits and about 850 deaths each year. Those are national figures. They do not predict one person.

How unpredictable the first hours can be is the timeline guide. The symptoms themselves are the subject here.

The symptom groups clinicians name

NIAAA, citing the DSM-5-TR, lists tremor, sweating, elevated pulse and blood pressure, insomnia, anxiety, nausea or vomiting, seizures, and delirium tremens. Many people with alcohol use disorder also feel dysphoria, a low or uneasy mood, and irritability as alcohol wears off. NIAAA's consumer handout puts the common picture in plainer words: shakes, nausea, vomiting, headaches, sweating, and feeling irritable. It then names the dangerous end: seizures, which the handout also calls convulsions, and confusion. If severe withdrawal, sometimes called DTs, is untreated, the handout says it can kill you.

A separate screening question uses a wider set of feelings that can show up as alcohol wears off, including trouble sleeping, shakiness, irritability, anxiety, low mood, restlessness, nausea, sweating, or sensing things that are not there. Those feelings can be part of deciding whether an alcohol use disorder is present. They are not a home test, and milder symptoms do not prove the severe ones will stay away.

Delirium tremens is the confused, unstable end of withdrawal, not a nickname for a bad hangover. Next-day symptoms are the hangover guide. A seizure does not arrive with time to pack a bag. Do not start a leftover benzodiazepine from someone else's bottle. That is not the monitored care NIAAA describes.

Medical detox is monitoring plus a clinician's medicine

NIAAA's treatment navigator describes medical detoxification as getting alcohol out of a person's system. When someone who has been drinking heavily for a prolonged period stops suddenly, withdrawal can be painful or dangerous. Symptoms can include nausea, a rapid heart rate, seizures, or other problems. Doctors can prescribe medications that make the process safer and less distressing.

Some withdrawal can be managed in an outpatient detox setting. Intensive inpatient detox is for people at risk of life-threatening symptoms. Assessment tools exist to help predict who is at high risk. Those tools belong to clinicians who can see the person.

Treatment of acute withdrawal symptoms includes benzodiazepines, which NIAAA calls the option with the deepest evidence, along with other medicines a clinician may add. That is a description of medical care. It is not permission to take a benzodiazepine from a cabinet. The FDA boxed warning says that stopping a benzodiazepine abruptly, or cutting the dose quickly, can cause serious withdrawal, including seizures. That separate risk is the benzodiazepine guide. Do not use one drug's withdrawal to treat the other's.

Naltrexone, acamprosate, and disulfiram do not help withdrawal symptoms. Other medicines can prevent dangerous withdrawal. The medicines used for withdrawal do not, by themselves, change drinking afterward, so a plan for care after the danger passes still matters. The consumer handout also says treatment programs usually do not offer medical management of withdrawal, and that help with that problem comes from a health care provider. A residential brochure is not the same thing as a monitored detox. Which symptoms mean emergency care now is the emergency guide. Why a nonmedical setting is the wrong default after severe withdrawal in the past is the home-versus-medical guide.

Detox is not the treatment

Detox alone is not the same as treatment. It can stabilize a person. It does not teach how to spot situations that lead back to heavy drinking, how to refuse a drink, or how to handle stress without alcohol. People who go through detox without more treatment are far more likely to return to drinking.

NIAAA's treatment article adds the time scale. Most alcohol use disorder treatment happens in outpatient settings. A small share of people need intensive inpatient or outpatient detox. Continued care, in a residential setting, an outpatient setting, or both, is often needed. Across settings, a course of treatment is measured in months, not days or weeks. If you are unsure which level fits, get a full assessment from a specialist.

There is no drink-counting chart, no hour-by-hour home schedule, and no dose here. If withdrawal may be a concern, talk with a health care provider before you stop.

Common Questions

What do alcohol withdrawal symptoms feel like?

NIAAA lists tremor, sweating, a fast pulse and higher blood pressure, insomnia, anxiety, and nausea or vomiting, and also seizures and delirium tremens. A consumer handout adds headaches and irritability. Many people also feel low or irritable as alcohol wears off. The list is not a score you can pass at home.

Does heavy daily drinking mean I should detox in a hospital?

It means you should talk to a clinician before you stop. NIAAA says a sudden stop after chronic heavy drinking can be life-threatening, that up to half of people with alcohol use disorder have some withdrawal, and that a smaller share need medical monitoring. Some of that care can be outpatient. Intensive inpatient detox is for people at risk of life-threatening symptoms. A clinician has to sort those groups.

Which symptoms are an emergency?

Call 911 for a seizure, collapse, trouble breathing, or severe confusion. NIAAA says untreated severe withdrawal, sometimes called DTs, can kill. Do not drive someone who is still seizing. For a mental health crisis, call or text 988.

Will naltrexone, acamprosate, or disulfiram treat withdrawal?

No. NIAAA's handout says those three medicines do not help withdrawal symptoms. Other medicines, chosen by a clinician, are used to prevent dangerous withdrawal. The withdrawal medicines do not, by themselves, change drinking afterward.

Can I follow a taper from a website?

No. There is no drink schedule, medicine list, or dose here. NIAAA says doctors can prescribe medicine so withdrawal is safer, and that detox without more treatment leaves people much more likely to return to drinking. Get a medical assessment.
