Hallucinations from alcohol withdrawal
What alcohol withdrawal hallucinations are like
Most alcohol hallucinations are visual or auditory. Some people may experience tactile hallucinations.
- Visual hallucinations: Seeing things that aren’t real
- Auditory hallucinations: Hearing things that aren’t real
- Tactile hallucinations: Feeling things that aren’t real, including formication, or a “crawling insects” feeling
Hallucinations are different from delusions. While a person experiencing hallucinations may see, hear, or feel things that aren’t real, someone with delusions has strong, fixed beliefs about something that’s not true.
Some people experience hypnagogic hallucinations, which are brief and take place as they fall asleep. These are different from hallucinations experienced during fully awake periods.
Stages of withdrawal where hallucinations are most likely
Alcohol hallucinations typically start within 48 hours of someone’s last drink and resolve within 72 hours after they start.
- Early stage (6–12 hours after last drink): Mild symptoms such as tremors and anxiety might appear.
- Acute stage (12–48 hours after last drink): Hallucinations, typically visual, can manifest alongside other symptoms like increased heart rate and blood pressure.
- Severe stage (48–72 hours after last drink): Delirium tremens (DTs) may occur, featuring severe confusion, agitation, and vivid hallucinations.
There is no exact way of knowing if a person undergoing alcohol withdrawal may experience hallucinations, but the likelihood increases significantly among those experiencing severe withdrawal symptoms such as DTs.
If you’ve experienced alcohol hallucinations before, having professional help can be the safest way forward. Get in touch with Santé Center to learn more about how long alcohol detox takes and what other alcohol withdrawal symptoms are common.
Causes of hallucinations during alcohol detox
Changes in brain chemistry
The brain’s chemistry undergoes substantial changes during alcohol detox. Chronic alcohol use depresses the central nervous system, and during detox, the sudden lack of alcohol causes the brain to become hyperactive.Role of neurotransmitters
- GABA (Gamma-Aminobutyric Acid): Alcohol enhances the effect of GABA, a neurotransmitter that inhibits brain activity. During detox, GABA levels drop, leading to increased brain activity.
- Glutamate: Alcohol inhibits glutamate, which excites brain activity. When drinking stops, glutamate levels surge, contributing to the brain’s hyperactivity and hallucinations.
Other contributing factors
Sleep loss, dehydration, nutritional deficiencies (including electrolyte imbalances), other medical or mental health conditions, and other substance use may all contribute to hallucinations. Whatever the reason, hallucinations from alcohol withdrawal pose many challenges that are best met through professional addiction treatment.Alcoholic hallucinations vs. delirium tremens
Alcoholic hallucinosis usually refers to visual, auditory, or tactile hallucinations during alcohol use or withdrawal, while awareness and orientation remain relatively clear. Delirium tremens is alcohol withdrawal delirium: a dangerous state involving impaired attention or awareness, confusion, autonomic instability, and sometimes hallucinations.1
Whatever the cause, hallucinations stemming from alcohol use or withdrawal need professional support. Don’t try to diagnose at home.
| Comparison | Alcoholic hallucinosis | Delirium tremens |
|---|---|---|
| Typical onset | Often within about 12–24 hours; may occur during heavy use or after alcohol is reduced | Often begins after 48 hours and may appear several days after the last drink |
| Awareness | Often oriented and aware that perceptions may not be real | Confused, disoriented, inattentive, or fluctuating awareness |
| Vital signs | May be relatively stable, but monitoring is still needed | May include fever, heavy sweating, fast heart rate, or high blood pressure |
| Duration | Often improves within about 48 hours, though symptoms may last longer | Varies and requires urgent hospital treatment |
| Danger level | Requires prompt assessment | Medical emergency |
| What to do | Contact a medical professional now; do not detox alone | Call 911 |
Signs of delirium tremens: When to call 911
Call 911 if a person in alcohol withdrawal has hallucinations with confusion, disorientation, severe agitation, fever, heavy sweating, a racing heart, seizures, fainting, or difficulty staying awake. Keep them away from driving, stairs, weapons, and other immediate hazards while emergency help is on the way. Withdrawal seizures can occur before DTs and are themselves an emergency. Do not give alcohol or unprescribed medication to control symptoms. If you or a loved one has experienced withdrawal complications before or has a history of heavy drinking, consider medically supervised detox to monitor severe symptoms.Can drinking cause hallucinations or psychosis?
Yes. Heavy drinking and alcohol withdrawal can both contribute to hallucinations, though they may have different root causes.
Alcohol hallucinosis is an alcohol-induced psychotic disorder. Psychosis includes more than hallucinations. It’s a disorder where someone loses touch with reality. Hallucinations are common in psychosis alongside paranoia, delusions, and disorganized thinking.
Alcohol- or drug-induced psychosis needs medical attention, as symptoms can get out of control quickly.
Who is most at risk of hallucinations from alcohol withdrawal?
- Age: Older adults may have a higher risk due to prolonged alcohol use and age-related brain changes.3
- Gender: Men may be more likely to experience severe withdrawal symptoms, including delirium.4
- Drinking and withdrawal history: Long-term, heavy drinkers face more significant risks. Those who experienced complications during withdrawal, including hallucinations, seizures, or delirium, are at higher risk.
- Medical and mental health conditions: Having a co-occurring condition may raise the risk of withdrawal complications.
Treatment for hallucinations from alcohol detox
Professional alcohol detox and a credible addiction treatment center will use a variety of approaches to address hallucinations from detox and withdrawal, such as:
Medical interventions
- Medications: Benzodiazepines are commonly prescribed to manage withdrawal symptoms and prevent seizures and hallucinations.
- Monitoring: Continuous medical supervision in a clinical setting can ensure immediate intervention if severe symptoms arise.
Therapy and support groups
- Cognitive-behavioral therapy (CBT): Helps address the psychological aspects of addiction and withdrawal.
- Support groups: Organizations like Alcoholics Anonymous provide a supportive community and practical coping strategies.
A supervised detox environment ensures safety and increases the likelihood of successful withdrawal by providing medical and emotional support.

Frequently asked questions
Can alcohol withdrawal cause psychosis?
Can alcohol withdrawal cause psychosis?
Yes. Alcohol withdrawal may involve hallucinosis, alcohol withdrawal delirium, or alcohol-related psychosis. All deserve medical attention.
Can drinking alcohol cause paranoia?
Can drinking alcohol cause paranoia?
Heavy drinking or withdrawal can occur with suspiciousness, persecutory beliefs, hallucinations, or delusions. Paranoia can also have other medical, medication-related, substance-related, or mental health causes. New or worsening symptoms need professional evaluation.
Can alcohol withdrawal cause delusions?
Can alcohol withdrawal cause delusions?
Yes. A delusion is a fixed false belief, while a hallucination is a false sensory perception. Delusions may occur with alcohol-related psychosis or delirium and require medical assessment, especially when the person is confused or unsafe.
Can alcohol-induced psychosis become permanent?
Can alcohol-induced psychosis become permanent?
Many episodes improve with abstinence and treatment, but some symptoms can persist or reveal another condition. Ongoing hallucinations or delusions need a full medical and psychiatric evaluation.
Can you have hallucinations without DTs?
Can you have hallucinations without DTs?
Yes. Alcoholic hallucinosis may cause hallucinations while the person remains oriented and aware. DTs involve delirium, including confusion or impaired awareness, and is a medical emergency. Because symptoms can change, any withdrawal hallucination still needs prompt medical care.
