Alcohol withdrawal can become a medical emergency. One of its most serious complications is delirium tremens (DTs), also called alcohol withdrawal delirium. DTs can cause sudden, severe confusion, worsen quickly, and require immediate hospital treatment.
Call 911 if someone develops severe confusion, hallucinations, a seizure, fever, or an irregular heartbeat after stopping or cutting back on alcohol. Do not wait for a detox admission or try to manage these symptoms at home.
If you drink heavily on a regular basis, seek medical guidance before stopping or sharply reducing how much you drink.
What Is Delirium Tremens?
Delirium tremens is a severe form of alcohol withdrawal that can occur after a person with physical dependence stops drinking or substantially reduces alcohol use.
Its defining feature is delirium: a significant disturbance in attention, awareness, and thinking. Someone may become disoriented, struggle to follow a conversation, or seem unable to understand what is happening around them.
DTs are more than shaking, anxiety, or a difficult night’s sleep. They require urgent medical evaluation and treatment.
Warning Signs That Require Emergency Care
Call 911 if someone withdrawing from alcohol develops:
Severe confusion or disorientation, such as not knowing where they are
Hallucinations, including seeing, hearing, or feeling things that are not there
A seizure
Fever
An irregular heartbeat
Marked agitation, heavy sweating, and a very rapid pulse can also accompany severe withdrawal. Do not wait for every symptom to appear before seeking help.
You do not need to determine whether the person definitely has DTs. Other medical emergencies can cause similar symptoms and also need prompt evaluation.
When Do DTs Usually Start?
DTs often begin 48 to 96 hours after the last drink, though they can start later. A sharp reduction in heavy, regular drinking can also trigger withdrawal. If someone develops severe confusion, hallucinations, or a seizure, call 911 immediately, even if their last drink was more recent.
Are Alcohol Withdrawal Seizures the Same as DTs?
No. Withdrawal seizures and alcohol withdrawal delirium are distinct complications, although a person may experience both.
Seizures often occur earlier in withdrawal and can happen without other prominent symptoms. A seizure requires emergency medical attention whether or not the person appears confused afterward.
Similarly, hallucinations can occur without delirium. They still require urgent assessment; someone at home should not try to distinguish between different withdrawal syndromes before getting help.
Who Is at Greater Risk?
Factors associated with severe or complicated alcohol withdrawal include:
Previous DTs or alcohol withdrawal seizures
Repeated episodes of withdrawal
A long history of heavy, regular drinking
Significant medical illness
Older age
Dependence on benzodiazepines or other sedating medications
A person does not need every risk factor to develop serious withdrawal. Mild symptoms at the beginning do not reliably establish that the rest of withdrawal will be mild.
Tell the evaluating provider about previous withdrawal experiences, all substances used, prescribed medications, and recent health concerns.
What Should You Do While Waiting for Emergency Help?
Call 911 and follow the dispatcher’s instructions. Explain that alcohol withdrawal may be involved and describe what you are observing.
If known, share:
When the person last drank or substantially reduced drinking
Their usual drinking pattern
Any history of withdrawal seizures or DTs
Medications or other substances they may have taken
Stay nearby if it is safe to do so, and let the dispatcher know if the person’s condition changes. Do not let the person drive or delay emergency care while contacting treatment programs.
How Are DTs Treated?
DTs require hospital care. Treatment includes medication to control withdrawal, close observation, and monitoring of vital signs and other medical needs. Some people require intensive care.
The American Society of Addiction Medicine recommends close nursing observation for alcohol withdrawal delirium, with continuous individual observation for patients who are agitated and disoriented. Hospital teams also evaluate other possible causes of confusion and address accompanying medical problems.
Subacute residential detox does not replace hospital treatment for suspected DTs.
Can Medical Care Reduce the Risk of Severe Withdrawal?
Early assessment and appropriate medication management can reduce the risk of withdrawal progressing to severe complications. They cannot guarantee that complications will never occur.
If you drink heavily or regularly, seek medical guidance before stopping or sharply reducing your drinking. A provider can review your history and recommend an appropriate setting for withdrawal management.
If you have already stopped and are developing symptoms, seek medical care promptly. Emergency warning signs require 911 rather than a routine appointment.
