Generic Antabuse Information

Introduction

Antabuse (active ingredient Disulfiram) is a medication classified under the groups General health and Alcoholism. It is primarily prescribed to help people with alcohol dependence maintain abstinence by producing an acute physical reaction if alcohol is consumed. In the United Kingdom, Antabuse is listed on the NHS formulary and is also available through private prescribers. Although originally developed by Roche, the drug is now manufactured by several licensed pharmaceutical worldwide. In addition to its main indication for alcohol‑use disorder, Disulfiram is occasionally investigated for off‑label uses such as certain dermatological conditions and as an adjunct in the management of cocaine dependence, but these applications remain experimental in the UK.

What is Antabuse?

Antabuse is a synthetic, orally administered small‑molecule drug whose sole active constituent is Disulfiram. It is sold as 250 mg tablets in the United Kingdom. The original brand‑name formulation, Antabuse, was introduced in the 195s by Roche; generic equivalents containing the identical active compound are now produced by multiple certified manufacturers. Our online pharmacy provides this generic alternative as a cost‑effective treatment option, matching the therapeutic profile of the branded product while adhering to the same quality standards required by the Medicines and Healthcare products Regulatory Agency (MHRA).

How Antabuse Works

Disulfiram interferes with the normal metabolic pathway of ethanol. After alcohol is ingested, it is first oxidised to acetaldehyde by the enzyme alcohol dehydrogenase (ADH). Acetaldehyde is then rapidly converted to acetate by acetaldehyde dehydrogenase (ALDH), a reaction that limits the buildup of the toxic intermediate. Disulfiram blocks ALDH by covalently binding to its active site, preventing the conversion of acetaldehyde.

When alcohol is consumed while Disulfiram is present in the body, acetaldehyde accumulates to concentrations that far exceed normal physiological levels. Elevated acetaldehyde triggers a predictable set of unpleasant symptoms—flushing, throbbing headache, nausea, vomiting, palpitations, and dyspnoea—commonly referred to as the Disulfiram‑alcohol reaction. The reaction typically begins within 10 minutes of drinking and can last for up to an hour, providing a strong behavioural deterrent against alcohol intake.

Pharmacokinetic data indicate that Disulfiram is absorbed rapidly from the gastrointestinal tract, reaching peak plasma concentrations within 1–2 hours. The drug’s half‑life is approximately 60–120 hours, reflecting extensive hepatic metabolism to di‑ethyl‑thiocarbamate (DETC) and other metabolites that maintain ALDH inhibition for several days after the last dose. This prolonged effect allows clinicians to prescribe a once‑daily regimen for most patients.

Conditions Treated with Antabuse

• Alcohol‑use disorder (AUD) – The principal, evidence‑based indication. Randomised controlled trials and meta‑analyses demonstrate that when combined with psychosocial counselling, Disulfiram reduces the frequency of heavy drinking episodes and increases the proportion of abstinent days compared with counselling alone. In the UK, the National Institute for Health and Care Excellence (NICE) recommends Disulfiram as an option for individuals who are motivated to remain abstinent and can adhere to the required monitoring schedule.

• Alcoholic liver disease (ALD) adjunct – In patients with early‑stage ALD who have ceased drinking, Disulfiram may support continued abstinence, thereby limiting further hepatic injury. Clinical guidance advises that Disulfiram should only be initiated after liver function tests have stabilised (e.g., bilirubin < 50 µmol/L, ALT/AST < 2 × ULN).

• Experimental/off‑label investigations – Small pilot studies have explored Disulfiram’s inhibitory effect on the enzyme dopamine β‑hydroxylase, suggesting potential utility in reducing cocaine cravings. Another line of research evaluates topical Disulfiram formulations for the treatment of pseudomembranous colitis caused by Clostridioides difficile, though these uses remain investigational and are not approved by the MHRA.

Suitable Candidates for Antabuse Treatment

• Motivated individuals – Patients who have expressed a clear commitment to abstinence and understand the required behavioural changes (e.g., avoidance of all alcoholic beverages, including those hidden in sauces or medications).

• Stable medical status – Candidates should have acceptable hepatic function (ALT/AST ≤ 2 × ULN), normal cardiac rhythm, and no severe psychiatric comorbidities that could impair adherence.

• Supportive environment – Access to regular follow‑up (typically weekly for the first month, then monthly) and a reliable support network (family, therapist, or support group) improve treatment success.

• Contraindications to avoid – Patients with known hypersensitivity to Disulfiram, severe liver disease (Child‑Pugh class C), severe cardiac disease (e.g., recent myocardial infarction, uncontrolled arrhythmias), or those who are unable to reliably abstain from alcohol should not receive Antabuse.

• Pregnancy and lactation – Use is contraindicated in pregnancy because Disulfiram crosses the placenta and may cause fetal toxicity. Breast‑feeding mothers should also avoid the drug, as it is excreted in milk.

Risks, Side Effects, and Interactions

Common

• Flushing and warmth – Often the first sign of the Disulfiram‑alcohol reaction.
• Headache – Ranges from mild throbbing to severe migraine‑like pain.
• Nausea or mild vomiting – Typically self‑limiting if the ingested alcohol volume is low.
• Metallic taste – Frequently reported when the medication is taken on an empty stomach.

Rare

• Peripheral neuropathy – Paresthesias or burning sensations, usually after prolonged therapy (> 6 months).
• Cutaneous reactions – Rash, urticaria, or photosensitivity in isolated cases.
• Psychiatric symptoms – Irritability, depression, or rare psychotic episodes; monitoring is advised in patients with pre‑existing mental health disorders.

Serious

• Severe Disulfiram‑alcohol reaction – Profuse vomiting, marked hypotension, tachycardia, bronchospasm, and syncope can occur after substantial alcohol intake. Immediate medical attention is required.
• Hepatotoxicity – Elevations of transaminases or bilirubin; in rare instances, acute hepatitis may develop. Liver function tests should be performed before initiating therapy and periodically thereafter.
• Cardiac arrhythmias – Particularly in patients with underlying heart disease; palpitations can progress to ventricular tachycardia.

Drug–Drug Interactions

• Metronidazole – Increases the risk of a disulfiram‑like reaction due to shared aldehyde‑inhibiting properties.
• CYP2E1 inducers (e.g., ethanol, isoniazid) – May alter Disulfiram metabolism, affecting efficacy.
• Warfarin – Disulfiram can potentiate anticoagulant effect; INR should be monitored closely.
• Phenytoin and carbamazepine – Accelerate hepatic metabolism, potentially reducing therapeutic effect.

Patients should disclose all current medications, including over‑the‑counter products and herbal supplements, to their prescriber.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing – The usual regimen in the UK is 250 mg once daily after a 12‑hour alcohol‑free interval. Some clinicians begin with a loading dose of 500 mg on day 1, followed by 250 mg daily, to achieve rapid enzyme inhibition.

• Administration guidance – Tablets should be swallowed whole with a full glass of water. Food does not impair absorption, but taking the dose with a meal can lessen gastrointestinal irritation.

• Missed dose – If a dose is forgotten and at least 12 hours have elapsed since the last intake, the patient may resume the regular schedule the following day. If the missed dose is identified within a 4‑hour window, the dose should be taken immediately; otherwise, skip and continue as normal.

• Overdose – Acute ingestion of more than 2 g (approximately eight tablets) can produce severe hepatotoxicity, profound nausea, and prolonged ALDH inhibition. Management is supportive, with focus on hydration, anti‑emetics, and monitoring of liver enzymes. Activated charcoal may be considered if ingestion is recent (< 1 hour).

• Alcohol exposure while on therapy – Even a single standard drink can trigger the reaction. Patients must avoid all sources of ethanol, including certain mouthwashes, cough syrups, and cooking wines.

• Comorbidities – In patients with chronic kidney disease, dose adjustment is not routinely required, but renal function should be monitored due to the possibility of metabolite accumulation.

FAQ

• Can Antabuse be taken with other medications for alcohol dependence, such as naltrexone?
  Yes, clinicians sometimes prescribe Disulfiram together with naltrexone when a combined pharmacological approach is deemed necessary. However, careful monitoring is essential because each drug has its own side‑effect profile and potential drug–drug interactions.

• Is there a risk of a reaction from using alcohol‑containing mouthwash while on Antabuse?
  Most standard mouthwashes contain negligible ethanol and are generally safe. Products with higher alcohol content (> 20%) should be avoided, as even small amounts can trigger a mild reaction in sensitive individuals.

• How should Antabuse be stored during the summer months in the UK?
  The medication should be kept in a cool, dry place, away from direct sunlight and temperatures exceeding 30 °C. A kitchen cupboard away from the stove or a bedroom drawer is suitable; refrigeration is not required.

• What does the tablet of Antabuse look like, and are there any identifiable markings?
  Antabuse tablets are round, white to off‑white, and typically bear the imprint “250 MG” on one side and the manufacturer’s logo on the other. Generic versions may have different embossings but will always list the dose strength.

• Can Antabuse be imported for personal use without a UK prescription?
  Under UK law, the importation of prescription‑only medicines for personal use is permitted if the quantity does not exceed a‑month supply and the patient holds a valid prescription from a UK‑registered prescriber. Importing without a prescription may be intercepted by customs authorities.

• Are there specific warnings for people of Asian descent taking Antabuse?
  Some pharmacogenetic studies suggest that certain Asian populations may metabolise Disulfiram slightly slower, potentially leading to higher plasma levels. Clinicians may opt for a lower initial dose and monitor liver function more frequently in these patients.

• What is the history behind the development of Antabuse?
  Disulfiram was first synthesised in the early 20th century as a by‑product of industrial chemistry. Its aversive properties were discovered in the 194s, leading to clinical trials that demonstrated its utility in reinforcing abstinence among alcohol‑dependent individuals. It received FDA approval in 1951 and was subsequently introduced to the UK market under the Antabuse brand.

• How does Antabuse compare with older aversive agents such as calcium carbimide?
  Calcium carbimide (Temposil) also induces a disulfiram‑like reaction but has a shorter duration of action and a higher incidence of gastrointestinal side effects. Disulfiram offers a longer therapeutic window and is generally preferred when an aversive strategy is indicated.

• Does the Disulfiram‑alcohol reaction affect drug testing results?
  The reaction raises acetaldehyde levels, which does not interfere with standard urine or blood drug screens. However, some specialised forensic tests may detect elevated acetaldehyde metabolites, indicating recent alcohol intake despite Disulfiram therapy.

• Is there any difference between the UK and US formulations of Antabuse?
  The UK formulation complies with the European Pharmacopoeia, whereas the US version follows the United States Pharmacopeia (USP) specifications. Both contain 250 mg of Disulfiram per tablet, but inert excipients such as binders or fillers may vary slightly, which could affect tolerability in individuals with hypersensitivity to certain additives.

• Can Antabuse be taken safely by someone low‑carb ketogenic diet?
  The diet itself does not interact with Disulfiram, but users should ensure adequate hydration and monitor for any unusual gastrointestinal symptoms, as both the medication and the diet can influence electrolyte balance.
