Delirium tremens (DTs) is a severe and life-threatening form of alcohol withdrawal that can have fatal complications. It is characterised by a rapid onset of confusion, tremors, hallucinations, and seizures, among other symptoms. While seizures are a symptom of DTs, they can also occur prior to the onset of DTs as a symptom of alcohol withdrawal. This is known as an alcohol withdrawal seizure, which may present as the only withdrawal symptom but typically resolves within 24 to 48 hours. Therefore, while seizures can occur independently of DTs, they can also precede or coincide with DTs as a symptom of this severe form of alcohol withdrawal.

Delirium tremens is a severe, life-threatening form of alcohol withdrawal
Delirium tremens (DTs) is a severe, life-threatening form of alcohol withdrawal that can occur when a person with alcohol use disorder suddenly stops drinking. DTs is a rare condition, affecting only around 3% to 5% of people with alcohol use disorder. However, it can be dangerous and even fatal if left untreated.
DTs typically occurs when someone with a history of heavy alcohol use abruptly stops drinking. This sudden cessation can cause a spike in the amino acid glutamate, leading to common DTs symptoms such as a sudden, extreme spike in blood pressure, tremors, severe excitability, and seizures. Other symptoms of DTs include confusion, agitation, anxiety, psychosis, hallucinations, sensory disruptions, disorientation, heavy sweating, nausea, vomiting, and irregular heart rate.
The symptoms of DTs usually appear two to three days after stopping alcohol consumption and can last for up to five days. In some cases, symptoms may occur as early as 48 hours after the last drink, and in others, they may not appear until seven to ten days later. It is important to note that DTs is a medical emergency, and those experiencing symptoms should seek immediate medical attention.
While DTs is a severe condition, it is treatable. Aggressive treatment, such as admission to a quiet intensive care unit, can improve outcomes. Benzodiazepines are the medication of choice for treating DTs, with lorazepam, diazepam, chlordiazepoxide, and oxazepam commonly used. Antipsychotics, such as low doses of haloperidol, may also be used to manage psychotic symptoms and reduce agitation. Thiamine (vitamin B1) is also recommended to be given intramuscularly due to the long-term nutritional deficit associated with heavy alcohol use.
To prevent DTs, it is crucial for those with alcohol use disorder to seek professional guidance and specialised programmes when reducing their alcohol intake or quitting drinking altogether. Primary care providers can guide individuals to resources and rehabilitation programmes that can help them safely reduce their alcohol consumption and improve their overall health and well-being.

It can cause seizures, hallucinations, and other dangerous symptoms
Delirium tremens (DTs) is a severe and often life-threatening form of alcohol withdrawal. It is characterised by a rapid onset of confusion, tremors, agitation, anxiety, psychosis, sensory disruptions, disorientation, heavy sweating, and seizures.
Seizures are a common symptom of delirium tremens, and they can be dangerous or even deadly if they turn into status epilepticus. They often start before the onset of DTs, and can recur. While seizures are a serious symptom, they are not the only dangerous aspect of DTs.
Hallucinations are another key symptom of DTs. People may see, hear, feel, smell, or even taste things that are not there. These hallucinations can be intense and disturbing, such as visions or feelings of insects, snakes, or rats. They may also be related to the environment, such as patterns on the wallpaper or in peripheral vision. Hallucinations can also be tactile, such as sensations of something crawling on the skin, known as formication.
Other dangerous symptoms of DTs include a sudden, extreme spike in blood pressure, severe excitability, and changes in body temperature, breathing, or blood circulation. These changes can lead to life-threatening complications such as sepsis, irregular heartbeat, trouble breathing, or an electrolyte imbalance.
DTs typically occur when someone with alcohol use disorder suddenly stops drinking, particularly if they have a history of chronic alcohol use and severe alcohol withdrawal symptoms. It is a rare condition, affecting only about 3-5% of people with alcohol use disorder. While DTs is a severe condition, it is treatable, and immediate medical care can improve outcomes.

DT occurs when someone with alcohol use disorder suddenly stops drinking
Delirium tremens (DTs) is a severe, life-threatening form of alcohol withdrawal that can happen when a person with alcohol use disorder suddenly stops drinking. It is a rare condition that occurs in about 5% of people with alcohol use disorder. DTs typically occur in people with a history of chronic alcohol use and those who have previously experienced severe alcohol withdrawal symptoms.
DTs is characterised by a rapid onset of confusion, tremors, agitation, anxiety, psychosis, sensory disruptions, disorientation, heavy sweating, and seizures. These symptoms can appear as early as 6 hours after the cessation of alcohol use, but typically develop 2 to 3 days after the stopping of heavy drinking, and can last for up to 5 days. In some cases, DTs can lead to life-threatening complications such as sepsis, irregular heartbeat, trouble breathing, seizures, or an electrolyte imbalance.
The risk of developing DTs can be reduced by gradually reducing alcohol intake over time, rather than stopping abruptly. If a person with alcohol use disorder wants to stop drinking completely, it is recommended that they seek medical guidance and specialised programs that can help them safely reduce their alcohol intake. Proper and prompt treatment of alcohol withdrawal can potentially lower the risk of symptoms developing into DTs.
If DTs occur, it is a medical emergency and aggressive treatment is required to improve outcomes. Treatment in a quiet intensive care unit with sufficient light is often recommended, along with the administration of benzodiazepines such as lorazepam, diazepam, and chlordiazepoxide. Antipsychotics, such as haloperidol, may also be used to help reduce problematic behaviours and manage psychotic symptoms. While DTs can be life-threatening, it is a treatable condition and with proper medical care, the risk of mortality can be significantly reduced.

DT is uncommon, affecting 3-5% of people with alcohol use disorder
Delirium tremens (DTs) is a severe and dangerous form of alcohol withdrawal that can sometimes be life-threatening. It is uncommon, affecting only 3-5% of people with alcohol use disorder (AUD). However, it is important to note that up to half of people with AUD will develop some form of withdrawal symptoms upon reducing their alcohol consumption.
DTs typically occurs when a person with AUD suddenly stops drinking entirely. It is characterised by a rapid onset of confusion, usually occurring around two to three days into the withdrawal process and lasting for a similar length of time. The condition can be identified by a range of symptoms, including shaking, shivering, irregular heart rate, heavy sweating, hallucinations, and seizures. These symptoms can be extremely dangerous, and in some cases, seizures can even lead to status epilepticus, which can be deadly.
The risk factors for developing DTs include being an adult man, particularly if one is white, young, and unmarried. Additionally, those with a history of heavy or frequent alcohol use, even if it has caused physical or emotional harm, are more likely to experience DTs. It is also worth noting that certain mental health issues, such as depression, post-traumatic stress disorder, or bipolar disorder, can increase the likelihood of experiencing hallucinations during DTs.
While DTs is uncommon, it is a serious condition that requires immediate medical attention. Treatment options include medication such as benzodiazepines and antipsychotics, as well as supportive care in a quiet intensive care unit with sufficient light. Seeking professional guidance before abruptly discontinuing alcohol consumption is crucial to preventing and managing DTs effectively.
Although DTs is uncommon, affecting only a small percentage of individuals with AUD, it poses a significant risk to those who develop the condition. Therefore, it is essential to seek professional support when reducing alcohol intake or quitting entirely to ensure a safe and effective approach to improving one's health.

It is treatable and preventable with proper medical care and guidance
Delirium tremens (DTs) is a severe, life-threatening form of alcohol withdrawal that can emerge when someone suddenly stops drinking. It is mainly caused by a long period of heavy drinking being stopped abruptly. DTs occur in 5–10% of alcoholics and carry up to 15% mortality with treatment and up to 35% mortality without treatment. The most common conditions leading to death in patients with DTs are respiratory failure and cardiac arrhythmias.
It is important to seek medical treatment while experiencing the symptoms of DTs. Symptoms can still progress and worsen once manifested, and the condition can be fatal if untreated. Supervised medical detox can help mitigate the condition. Treatment in a quiet intensive care unit with sufficient light is often recommended. Benzodiazepines are the primary treatment for alcohol withdrawal, and large amounts of sedatives may be required to control symptoms. Non-benzodiazepines are often used as adjuncts to manage the sleep disturbance associated with the condition. Antipsychotics like haloperidol can also be used to manage psychotic symptoms like hallucinations.
To prevent DTs, it is important to lower alcohol intake or quit drinking entirely. This can be done safely with the guidance of a primary care provider, who can direct patients to alcohol rehabilitation care and specialised programmes that can help.
