Disulfiram is a medication commonly prescribed to help individuals with alcohol use disorders (AUD) maintain sobriety. It works by causing a severe disulfiram-alcohol reaction when alcohol is consumed, making drinking a highly unpleasant experience. This reaction, combined with therapy and counseling, serves as an effective tool in encouraging long-term sobriety.
Understanding how disulfiram works, its potential side effects, and the symptoms of a disulfiram-alcohol reaction is essential for anyone considering it as part of their treatment plan.

What is Disulfiram Used For?
Disulfiram is prescribed to treat alcohol use disorders by discouraging alcohol consumption. When alcohol is ingested, disulfiram blocks an enzyme that helps break down acetaldehyde, a toxic byproduct of alcohol.
As acetaldehyde builds up in the body, the individual experiences unpleasant symptoms such as:
- Nausea and vomiting
- Flushing
- Sweating
- Headaches
This unpleasant experience makes drinking alcohol while on disulfiram undesirable, reinforcing the decision to stay sober.

What Happens When You Drink Alcohol on Disulfiram?
When someone takes disulfiram and then consumes alcohol, they trigger the disulfiram reaction with alcohol. Disulfiram blocks the enzyme responsible for breaking down acetaldehyde, causing it to accumulate in the bloodstream.
The severity of the disulfiram-alcohol reaction varies depending on several factors, including metabolism and the amount of alcohol consumed. Even small amounts of alcohol can trigger this reaction, which can last for hours, acting as a powerful deterrent against drinking.
Symptoms of Disulfiram Alcohol Reaction
The disulfiram-alcohol reaction can cause a range of symptoms that are uncomfortable and can sometimes be severe.
These include:
- Flushed skin
- Nausea and vomiting
- Increased heart rate
- Low blood pressure
- Headaches
- Excessive sweating
- Dizziness
- Shortness of breath
- Chest pain
These symptoms typically start within minutes of alcohol consumption and can persist for hours. The intensity of these symptoms depends on how much alcohol is consumed, the dosage of disulfiram, and the individual’s metabolic rate.
Wondering if disulfiram is right for you?
Consult a healthcare professional for personalized advice.
How Severe Can the Disulfiram Alcohol Reaction Be?
While the disulfiram-alcohol reaction is often unpleasant but not life-threatening, in severe cases, it can cause serious complications like:
- Cardiac arrhythmias
- Severe hypotension (low blood pressure)
- Seizures
- Heart failure
It’s critical to avoid alcohol while taking disulfiram to prevent these dangerous outcomes. If you experience yellowing of the skin or eyes, this could be a sign of liver damage, which may require immediate medical attention.

Effectiveness of Disulfiram for Alcoholism
Disulfiram is highly effective in treating alcohol use disorder (AUD), especially when used as part of a comprehensive treatment plan that includes therapy for alcohol use disorders. Studies show that disulfiram can help individuals stay sober by creating an aversion to alcohol.
However, its success is largely dependent on the person’s commitment to abstaining from alcohol and following the treatment plan. While disulfiram doesn’t offer a cure for alcoholism, it supports the recovery process by reinforcing the decision to avoid alcohol.
Disulfiram Alcohol Reaction Treatment: What to Do If It Happens?
If you or someone else experiences a disulfiram alcohol reaction, it’s essential to seek medical attention immediately. Depending on the severity, the reaction can range from mild discomfort to more serious complications.
Here’s what to do:
- Stop drinking alcohol immediately.
- Call your doctor or visit the emergency room for treatment.
- Stay calm and rest while waiting for medical help.
In severe cases, treatments may include IV fluids to restore fluid balance, medications to stabilize blood pressure and heart rate, and continuous monitoring in a medical facility.
