Yes, delirium tremens can be fatal. Delirium tremens, usually called DTs, is the most severe form of alcohol withdrawal. According to StatPearls, a medical reference from the National Library of Medicine, untreated DTs has carried a death rate as high as 37%. Fast diagnosis and hospital-level care bring that risk down sharply, which is why DTs is treated as a medical emergency.
Knowing the signs and the timing can save a life, including one in your own family.
What Is Delirium Tremens?
Delirium tremens, also called alcohol withdrawal delirium, is a sudden, severe state of confusion and nervous-system overdrive. It can develop when someone who’s been drinking heavily for a long time stops or sharply cuts back. Heavy drinking pushes the brain to adapt. It turns up its excitatory signals to offset alcohol’s sedating effect. Take the alcohol away and nothing’s holding that overactive system in check. For most people, the result is uncomfortable withdrawal. In a smaller group, the brain and body tip into delirium.Why Delirium Tremens Is Deadly
DTs reaches well past the mind. The same overdrive that causes confusion also strains the heart, muscles and lungs, along with the body’s ability to regulate temperature and fluids. StatPearls lists the main causes of death as:- Heart rhythm problems (arrhythmias)
- Severe muscle breakdown (rhabdomyolysis), which can damage the kidneys
- Respiratory failure
- Seizures
- Aspiration, or inhaling vomit or fluid into the lungs
Delirium Tremens Symptoms
DTs usually starts out looking like ordinary withdrawal (shakiness, sweating, anxiety) and then gets much worse. Signs include:- Severe confusion and disorientation (not knowing where they are, what day it is, or who people are)
- Agitation, restlessness or combativeness
- Hallucinations, often visual, such as seeing insects or people who aren’t there
- Heavy sweating and fever
- Racing heart and high blood pressure
- Severe tremor
- Trouble paying attention or following a conversation
- Seizures
Delirium Tremens Timeline
According to StatPearls, DTs can begin as early as 48 hours after the last drink, and symptoms typically last up to five days. Another StatPearls chapter notes delirium can appear at any point up to three to five days after stopping. That delay matters. Someone can seem past the worst of withdrawal on day one or two, then get much sicker.| Stage | Typical timing after last drink |
|---|---|
| Early withdrawal (tremor, sweating, anxiety) | Within hours |
| Withdrawal seizures | About 8 to 48 hours |
| Delirium tremens | From about 48 hours, up to 3 to 5 days |
| DTs symptoms resolve | Usually within about 5 days with treatment |
Who Gets Delirium Tremens?
Most people who go through alcohol withdrawal won’t develop DTs. StatPearls estimates that about 3% to 5% of people with alcohol withdrawal syndrome progress to delirium, and that the lifetime risk among people with alcohol use disorder is about 5% to 10%. Risk is higher for people who:- Have had delirium tremens before
- Have had alcohol withdrawal seizures
- Have another illness at the same time, such as an infection or liver disease
- Have been drinking heavily for many years
- Went a longer stretch drinking heavily before their last drink
- Are older
What to Do If You Think Someone Has DTs
Delirium tremens isn’t something to wait out at home. If someone who’s stopped or cut back on drinking becomes confused, sees or hears things that aren’t there, has a seizure, or seems to be burning up with a racing heart:- Call 911 right away.
- Stay with them and keep the area calm, quiet and well lit if you can.
- Don’t give them alcohol to “bring them down,” and don’t give them anyone else’s medication.
- If they have a seizure, move objects away, cushion their head and turn them on their side once the jerking stops.
- Tell responders when they last drank, how much they usually drink and any medical conditions or medications.
