DTs occur when a person who repeatedly drinks large amounts of alcohol suddenly stops or decreases the amount of alcohol consumed.
These factors increase your chance of developing DTs: History of heavy alcohol use and abuseHistory of DTs or other withdrawal symptoms
Other medical problems (in addition to
alcohol use disorder
Symptoms usually begin 3-7 days after suddenly stopping or decreasing alcohol intake. Symptoms may include: AnxietyConfusion and disorientation
Changing levels of alertness
Difficulty sleepingBad dreamsSevere agitationFeverHallucinations—the perception of a thing, voice, or person that is not present, both visual and auditoryDelusions—a false belief that is strongly heldTremors of the hands, head, or bodySevere sweatingRapid heartbeatNauseaRapid breathingSeizures
In severe cases, DTs can result in death, especially if untreated.
You will be asked about your symptoms and medical history. A physical exam will be done. The diagnosis of DTs is usually based on the symptoms and signs of the disorder
after stopping alcohol use.
Your bodily fluids may be tested. This can be done with blood tests.
Your brain activity may be tested. This can be done with an electroencephalogram
Images of your internal body structures can be taken with:
CT scanMRI scan
Treatment can be difficult. Clearing of DTs may begin in 12-24 hours, but may take up to 2-10 days. Treatment for alcohol abuse is necessary after DTs are under control.
Talk with your doctor about the best treatment plan for you. Options may include:
DTs may be treated with: Benzodiazepines to ease anxiety, withdrawal symptoms, and cognitive problemsAntiseizure medicationsAntipsychotics to manage hallucinations or other cognitive problemsPain relievers, such as acetaminophenMedications to control blood pressure and heart rate
Treatment for alcohol abuse may be done in a hospital setting or while living at home. It may involve individual or
group therapy. Many people seek support by participating in groups such as Alcoholics Anonymous (AA).
To prevent having DTs, manage how you drink alcohol. If you do drink large amounts on a regular basis, do not suddenly decrease the amount or stop drinking on your own. Rather, get advice from your doctor on the safest way to lower your intake.
