What is Disulfiram?
Doctors use disulfiram (also known by the brand name Antabuse) to treat chronic alcoholism.
Disulfiram can work well for people who want to cut back on their drinking or stop drinking altogether, as a treatment of alcohol use disorder. If a person taking the medication drinks alcohol, they may have many unpleasant and even dangerous side effects. Most effective for people who are committed to their sobriety. Otherwise, a person could simply stop taking the medication if they decide to start drinking alcohol again.
Disulfiram was the first drug approved by the FDA for treating alcohol use disorder in 1951. The most common medication for alcoholism treatment in the 20th century was.
Today, doctors typically replace Antabuse or use it alongside newer drugs like Revia, Vivitrol (naltrexone), and Campral (acamprosate). These newer drugs work differently because they directly interact with brain chemistry.
How Does Disulfiram Work?
Disulfiram is different from newer drugs like Revia, Vivitrol, and Campral. These newer drugs work directly with brain chemistry to treat alcoholism, but disulfiram does not. Instead, it discourages the consumption of alcohol by interfering with the way your body digests and absorbs alcohol. This produces very unpleasant side effects, which make you not want to drink alcohol anymore.
Disulfiram does not treat alcohol withdrawal symptoms or reduce cravings. You should take it regularly by mouth in tablet form (250 mg or 500 mg tablets). People who use disulfiram for alcohol addiction treatment take it once per day.
Disulfiram is not available OTC and must be prescribed by a doctor. A medical doctor will also be able to determine if Antabuse is the right medication for your alcohol dependence treatment, based on your addiction treatment history or if there is a better alternative available.
What Happens If You Drink Alcohol While Taking Disulfiram?
- A disulfiram reaction with alcohol can occur if you drink while you’re taking the medication. This reaction will produce very unpleasant or dangerous side effects like:Sweating
- Flushing of the upper chest and face
- Hyperventilation
- Respiratory problems
- Bad breath
- Blurry vision
- Extreme thirst
- Throbbing of the head and neck
- Nausea
- Vomiting
- Chest pain/palpitations
- Low blood pressure
- Fast heart rate
- Vertigo
- Confusion
- Weakness
Other more severe and rare symptoms of a disulfiram reaction with alcohol can include:
- Cardiac arrest
- Irregular heartbeat
- Heart attack
- Acute congestive heart failure
- Seizures
- Unconsciousness
- Death
So, how is this disulfiram reaction caused?
Normally, the body breaks down alcohol in two steps: first into acetaldehyde, then into acetic acid. Disulfiram blocks the second step, causing acetaldehyde to build up and trigger unpleasant symptoms. This reaction discourages drinking, though some may avoid it by skipping doses. Even small amounts of alcohol from products like mouthwash, sauces, or vinegar can cause a reaction for up to 14 days after taking disulfiram.
Disulfiram Side Effects
If prescribed disulfiram for alcohol addiction, you may experience side effects. Common ones include fatigue, drowsiness, headache, acne, rash, and a metallic taste. More severe reactions can involve nerve damage, hepatitis, psychosis, or inflammation of the optic nerve. These effects often improve once your doctor reduces the dosage.

What Are the Symptoms of Disulfiram Withdrawal?
Disulfiram does not produce any known withdrawal symptoms.
How Long Does Disulfiram Stay In Your System?
The half-life of disulfiram is 60 to 120 hours, which is a relatively slow rate of elimination. Most medications can last 12 hours. If you take disulfiram and want to drink heavily again, wait at least two weeks. This allows the medication to leave your system before you drink alcohol.
If you’ve been prescribed disulfiram to treat alcohol use disorder (AUD) or heavy drinking, it’s important to take it daily as directed by your medical care provider. Once you’ve maintained sobriety for a significant period, consult your doctor to discuss whether it’s time to discontinue the medication.
Is Disulfiram Safe to Use?
Disulfiram is safe for treating a medical condition when taken as prescribed by a healthcare professional. However, it may not be suitable for individuals with certain conditions such as schizophrenia, liver or kidney disease, epilepsy, or allergies to sulfur compounds. Before starting outpatient treatment, your doctor will evaluate your health history to ensure it’s a safe option.
Is Antabuse Discontinued?
According to the American Society of Health-System Pharmacists, several pharmaceutical companies have discontinued disulfiram tablets, including:
- Teva Pharmaceuticals
- Mylan
- Rising Pharmaceuticals
Currently, Alvogen is the only supplier of disulfiram tablets.
Disulfiram for Alcohol Addiction Treatment
Disulfiram is not intended to be taken on its own. Instead, it should be used in combination with supportive addiction treatment care and psychotherapy.
Depending on the severity of your addiction and mental health condition, a combination of the following treatment programs may help you overcome your alcohol addiction while you’re taking disulfiram:
- Medical detox for alcohol addiction: How to remove disulfiram from body? Medical detox programs provide 24/7 monitoring of your vitals to ensure that you’re safely progressing through alcohol withdrawal. A team of doctors and nurses will administer medication as needed to treat any withdrawal symptoms you experience and licensed clinical counselors will provide therapeutic support to help you manage the psychological symptoms of withdrawal, such as depression, anxiety, and cravings.
- Residential rehab for alcohol addiction: If your alcohol addiction is severe or you’ve struggled with it for years, a residential addiction treatment program may provide the structure and support you need to get sober for good. Residential alcohol rehab offers individualized care and round-the-clock access to treatment professionals at a licensed facility where you will live for the duration of treatment. Treatment includes evidence-based methods like cognitive behavioral therapy, group counseling, individual and family counseling, 12-Step facilitation, and specialized therapies like music therapy or art therapy. These treatment methods will help you establish a firm foundation of sobriety, gain life skills, learn how to prevent relapse and manage cravings, and give you the tools and peer support you need to stay sober.
- Intensive outpatient rehab for alcohol addiction: An IOP (intensive outpatient program) offers structured, comprehensive treatment with a more flexible schedule. You’ll attend treatment sessions at an outpatient facility several times a week where you’ll receive a high level of support and structure to help you succeed. Online IOP is another option for those who are unable to attend outpatient rehab in-person or prefer to attend online instead.
- Sober living programs: Sober living programs provide safe and supportive housing for people in recovery. Residents must commit to avoiding all alcohol and drug use and adhere to the community rules. These homes or apartment units are designed with addiction recovery in mind, providing structured recovery programming, regular drug testing, and peer support services like employment assistance, educational planning, volunteer placement, and more.
Most addiction treatment facilities accept health insurance benefits through providers like Aetna, Cigna, UnitedHealthcare, or Beacon/ValueOptions, and others. If you don’t have insurance, some alternative payment options may include:
- Employee Assistance Programs (EAPs)
- Third-party healthcare loans
- Personal loans from loved ones
- Healthcare credit cards
If you or a family member are struggling to pay for an alcohol addiction treatment program, you may also qualify for some scholarships or grants offered through some private rehab centers or nonprofit organizations. You can ask the treatment provider or organization directly if they provide this type of assistance.
Ultimately disulfiram may be one aspect of your substance use disorder treatment, but supportive care and comprehensive, individualized treatment will play a big role in helping you stay sober.

Disulfiram Treatment: What You Need to Know in 2026
Disulfiram (commonly known by the brand name Antabuse) remains one of the most established medication-assisted treatment options for alcohol use disorder. As research continues to evolve, understanding how this medication works—and whether it’s right for your recovery journey—is more important than ever.
How Disulfiram Supports Alcohol Recovery
Disulfiram works by blocking the enzyme aldehyde dehydrogenase, which is responsible for breaking down alcohol in the body. When someone taking disulfiram consumes alcohol, even in small amounts, they experience highly unpleasant reactions including nausea, vomiting, headache, chest pain, difficulty breathing, and flushing. This aversive response creates a powerful deterrent to drinking.
The medication is most effective when combined with comprehensive addiction treatment that includes therapy and counseling, peer support, and ongoing medical monitoring. At Nova Recovery Center, our clinical teams integrate medication-assisted treatment with evidence-based therapies to address both the physical and psychological aspects of alcohol dependence.
Is Disulfiram Right for Your Recovery?
Disulfiram may be an appropriate option if you:
- Are highly motivated to maintain abstinence from alcohol
- Have completed medical detoxification and are physically stable
- Understand the serious reactions that occur if you drink while taking the medication
- Are willing to commit to supervised medication compliance
- Have no contraindications such as severe heart disease, psychosis, or pregnancy
This medication requires careful medical supervision. Our addiction treatment specialists conduct thorough assessments to determine whether disulfiram is appropriate for your individual circumstances.
Integrating Disulfiram into Comprehensive Treatment
Medication alone is rarely sufficient for lasting recovery. Research consistently shows that the best outcomes occur when medication-assisted treatment is combined with:
- Individual and group therapy to address underlying causes of alcohol dependence
- Behavioral therapies such as cognitive behavioral therapy
- Family counseling to rebuild relationships and create supportive home environments
- Relapse prevention planning to identify triggers and develop healthy coping strategies
- Aftercare and alumni support to maintain long-term sobriety
Nova Recovery Center offers disulfiram as part of our comprehensive addiction treatment programs in Austin, Houston, San Antonio, and Colorado Springs. Whether you’re seeking inpatient rehab or intensive outpatient treatment, our medical teams provide ongoing monitoring and support.
Important Safety Considerations
If you’re prescribed disulfiram, you must avoid all sources of alcohol, including:
- Alcoholic beverages of any kind
- Cough syrups and cold medications containing alcohol
- Mouthwash and other oral hygiene products with alcohol
- Certain sauces, vinegars, and food products prepared with alcohol
- Aftershave, cologne, and topical products containing alcohol
The disulfiram-alcohol reaction can occur with even trace amounts and can be severe. Always read product labels carefully and inform all healthcare providers that you’re taking this medication.
Frequently Asked Questions About Disulfiram
How long does disulfiram stay in your system?
Disulfiram can remain active in your body for up to two weeks after your last dose. This means you must continue to avoid alcohol for at least 14 days after stopping the medication, as the aversive reaction can still occur during this period. Your treatment team will provide specific guidance based on your dosage and individual metabolism.
What happens if you drink alcohol while taking disulfiram?
Drinking alcohol while taking disulfiram causes a severe reaction within 10-30 minutes that can include flushing, throbbing headache, nausea, violent vomiting, chest pain, difficulty breathing, sweating, anxiety, confusion, and blurred vision. In severe cases, the reaction can lead to respiratory depression, cardiovascular collapse, seizures, or death. This reaction is the medication’s intended deterrent effect, but it can be medically dangerous and requires immediate emergency care.
Can disulfiram be used for drug addictions other than alcohol?
While disulfiram is FDA-approved only for alcohol use disorder, some research has explored its potential use for cocaine dependence. However, the evidence remains limited and it is not currently a standard treatment for other substance use disorders. If you’re struggling with addiction to substances other than alcohol, our clinical team can recommend appropriate evidence-based treatment options tailored to your specific needs.
How long do you typically take disulfiram during alcohol addiction treatment?
The duration of disulfiram treatment varies based on individual circumstances, recovery goals, and clinical progress. Some people take it for several months during early recovery, while others may continue for a year or longer. The medication is most effective when used as part of a comprehensive treatment plan that includes therapy, support groups, and lifestyle changes. Your treatment team will regularly reassess whether continued medication is beneficial for your recovery.
Does insurance cover disulfiram treatment?
Most insurance plans cover disulfiram as part of medically necessary addiction treatment. Coverage varies by plan, but medication-assisted treatment is generally included under mental health and substance use disorder benefits. Nova Recovery Center works with most major insurance providers and our admissions team can verify your specific coverage, including medication costs, before you begin treatment. Call us at (512) 893-6955 to discuss your insurance benefits.
What are the side effects of disulfiram when you’re not drinking?
Even when you avoid alcohol completely, disulfiram can cause side effects including drowsiness, fatigue, headache, metallic or garlic-like aftertaste, and skin rash. Rarely, it can cause more serious effects such as liver damage, optic neuritis, or peripheral neuropathy. Regular medical monitoring with blood tests is important to detect any adverse effects early. Most side effects are mild and diminish over time, but you should report any concerning symptoms to your treatment team immediately.
