Generic Disulfiram Information

Introduction

Disulfiram is a prescription medication used primarily to support the treatment of alcohol dependence. In Hong Kong it is classified under the therapeutic group “Alcoholism” and is available only with a qualified medical prescription. The active compound, Disulfiram, produces a predictable physical reaction when alcohol is consumed, thereby discouraging drinking and assisting patients who have decided to remain abstinent. Besides its main indication, Disulfiram may be prescribed off‑label for certain drug‑induced conditions, but its core clinical role remains the reinforcement of alcohol‑abstinence programmes.

What is Disulfiram?

Disulfiram is the generic version of the original brand Antabuse, which was first introduced in the United States in the 195s. Both formulations contain the same active compound, Disulfiram, and act in an identical biochemical manner. Our online pharmacy provides this generic alternative as a cost‑effective treatment option without compromising efficacy or safety. The medication is supplied as oral tablets, typically 250 mg per tablet, manufactured by several internationally regulated pharmaceutical companies that meet Good Manufacturing Practice (GMP) standards.

How Disulfiram Works

Disulfiram inhibits the enzyme aldehyde dehydrogenase (ALDH) in the liver. Normally, after alcohol is metabolised to acetaldehyde, ALDH converts acetaldehyde to acetate, a non‑toxic substance. When ALDH is blocked, acetaldehyde accumulates to levels that cause unpleasant physiological responses—flushing, tachycardia, nausea, vomiting, headache, and hypotension. The reaction usually begins within 10 minutes of alcohol ingestion and can last for up to an hour, depending on the dose of Disulfiram and the amount of alcohol consumed. Because the effect is predictable, patients learn to associate drinking with severe discomfort, which reinforces abstinence. The drug has a relatively long half‑life (≈ 60–120 hours), allowing once‑daily dosing after the initial titration phase.

Conditions Treated with Disulfiram

• Alcohol Dependence (Alcohol Use Disorder).
  The primary indication approved by the Hong Kong Department of Health is the management of chronic alcoholism when combined with counseling and psychosocial support. Clinical trials have shown that Disulfiram can reduce drinking days by 25–30 % compared with placebo when adherence is high.

• Off‑label Uses.
  In some jurisdictions, Disulfiram has been explored for the treatment of certain parasitic infections (e.g., giardiasis) and as an adjunct in cocaine dependence, but these uses are not formally approved in Hong Kong and remain experimental---

Patient Groups Most Likely to Benefit

• Motivated Individuals Seeking Abstinence.
  Patients who have already committed to stop drinking and who can attend regular follow‑up appointments are ideal candidates.

• Patients in Structured Rehabilitation Programs.
  When Disulfiram is combined with counseling, group therapy, or outpatient monitoring, adherence rates improve, and the deterrent effect is maximised.

• Adults with a History of Relapse.
  Those who have repeatedly failed to maintain sobriety using counseling alone may benefit from the added pharmacologic deterrent.

• Contraindicated or Cautious Use.
  Disulfiram is not suitable for patients with severe cardiac disease, significant liver dysfunction, or known hypersensitivity to the drug. Pregnant or breastfeeding women should also avoid it, as safety data are insufficient.

Risks, Side Effects, and Interactions

Common

• Nausea, vomiting, and abdominal discomfort – usually mild and transient after the first few doses.
• Headache – reported in up to 15 % of patients.
• Skin rash or mild pruritus – often resolves without intervention.

Rare

• Peripheral neuropathy – occurring after prolonged; requires dose reassessment.
• epatotoxicity – elevated transaminases may appear; periodic liver function tests are advised.

Serious

• Disulfiram‑Alcohol reaction – severe flushing, hypotension, tachycardia, dyspnoea, and syncope. Immediate medical attention is required if symptoms are pronounced.
• Psychiatric disturbances – rare cases of depression or psychosis have been reported; discontinue the drug and seek psychiatric evaluation.
• Severe skin reactions – such as Stevens‑Johnson syndrome; treat as an emergency.

Important Drug–Drug Interactions

• Metronidazole and certain cephalosporins – may potentiate a disulfiram‑like reaction even without alcohol.
• Warfarin – Disulfiram can enhance anticoagulant effect; monitor INR closely.
• Phenytoin and carbamazepine – enzyme inducers that may reduce Disulfiram plasma levels, potentially decreasing efficacy.
• CYP2E1 substrates (e.g., acetaminophen) – caution due to additive hepatic stress.

Patients should always disclose their complete medication list, including over‑the‑counter drugs and herbal supplements, to the prescribing clinician.

Practical Use: Dosing, Missed Dose, Overdose

• Initiation Phase.
  The recommended starting dose is 250 mg once daily for 1–2 weeks. Some clinicians begin with 125 mg on alternate days to assess tolerance.

• Maintenance Phase.
  After the titration period, the usual maintenance dose is 250–500 mg once daily, taken with food to minimise gastrointestinal upset.

• Missed Dose.
  If a dose is missed for less than 24 hours, the patient should take it as soon as remembered, provided no alcohol has been consumed. If more than 24 hours have passed, skip the missed tablet and resume the regular schedule; do not double‑dose.

• Overdose Management.
  Symptoms of acute overdose may include severe nausea, vomiting, dizziness, and prolonged disulfiram‑alcohol reactions. Immediate medical attention is required. Gastric decontamination is not routinely indicated because the drug is rapidly absorbed; supportive care and monitoring are the mainstays of treatment.

• Precautions.
  Avoid all forms of alcohol, including in sauces, mouthwashes, cough syrups, and certain medications. Patients with hepatic impairment should undergo baseline liver function testing and be monitored regularly. Alcohol‑containing foods (e.g., desserts with rum flavor) should also be avoided.

FAQ

• Is Disulfiram available in both brand‑name and generic forms in Hong Kong?
  Yes, the medication is marketed under the brand name Antabuse and also as generic Disulfiram tablets. The generic version contains the identical active ingredient and is typically more affordable.

• What is the recommended storage condition for Disulfiram tablets?
  The tablets should be stored at room temperature, away from direct sunlight, excessive heat, and moisture. Do not store them in bathrooms or near kitchen ovens.

• Can I travel internationally with Disulfiram in my carry‑on luggage?
  Yes, provided you carry a copy of the prescription and the original pharmacy label. Some countries require a medical certificate, so it is advisable to check the destination’s import regulations before travel.

• Does Disulfiram interact with common over‑the‑counter pain relievers?
  While most NSAIDs (e.g., ibuprofen) are safe, acetaminophen should be used with caution because both drugs are metabolised by the liver, and combined use may increase hepatic stress.

• Are there special considerations for Asian patients taking Disulfiram?
  Pharmacogenetic studies suggest that some East Asian populations may experience a slightly higher rate of cutaneous reactions, but overall efficacy and safety remain comparable. Regular monitoring for skin rash is recommended.

• What packaging does Disulfiram come in when ordered online?
  Orders are shipped in sealed, tamper‑evident blister packs containing 30 tablets per bottle. Each bottle includes a printed label with dosage instructions, batch number, and expiry date.

• Can Disulfiram be imported for personal use without a prescription in Hong Kong?
  No. Hong Kong customs regulations require a valid prescription for any controlled medication, including Disulfiram. Our online pharmacy ensures the prescription requirement is met through professional evaluation.

• Is Disulfiram covered by Hong Kong’s public health insurance schemes?
  Currently, Disulfiram is not listed under the Hospital Authority’s subsidised drug formulary. Patients generally pay out‑of‑pocket or may seek private health‑insurance reimbursement where applicable.

• How does telemedicine affect the prescribing process for Disulfiram?
  Telemedicine consultations are accepted by the Hong Kong Medical Council as long as the prescribing clinician conducts a thorough assessment. Our online service incorporates a mandatory professional evaluation to meet these standards.
