Disulfiram
Disulfiram, commonly known as Antabuse, is a medication used to help individuals manage chronic alcoholism. It’s not a cure for alcohol dependence, but rather a deterrent; it creates unpleasant physical reactions when alcohol is consumed. The active ingredient, disulfiram, works by interfering with the body’s metabolism of alcohol, leading to a build-up of acetaldehyde – a toxic intermediate product. This buildup causes a range of symptoms that discourage further drinking.
The medication has been around for decades and was initially developed in the 1940s. While specific manufacturers may vary depending on location and availability, several pharmaceutical companies produce generic disulfiram tablets globally. It’s important to note that Antabuse is most effective when used in conjunction with counseling and support groups as part of a comprehensive alcohol treatment program. Think of it as a safety net, not a standalone solution.
Disulfiram doesn’t reduce the craving for alcohol; instead, it makes drinking an acutely unpleasant experience. This can be a powerful tool for maintaining sobriety, but requires strong commitment from the individual and understanding support from healthcare professionals. It’s crucial to remember that Antabuse is not suitable for everyone and should only be taken under strict medical supervision.
Forms & Dosages Available
Currently, disulfiram primarily comes in tablet form for oral administration. The standard dosage strengths available in the UK generally include 200mg and 400mg tablets. These tablets are typically film-coated to make them easier to swallow and mask any unpleasant taste. It’s important to follow your doctor’s instructions precisely regarding dosage, as it is tailored to individual needs and response to treatment.
Dosage isn’t a one-size-fits-all situation; the initial dose usually starts low – around 200mg daily – and can be gradually increased by a healthcare professional up to a maximum of 400mg per day, depending on how well it’s tolerated and its effectiveness. The tablets are generally taken once daily, ideally in the morning, to provide consistent coverage throughout the day.
Regarding splitting tablets, it’s best to consult with your pharmacist or doctor. Some film-coated tablets may be scored for easier division, but not all are designed to be split accurately, potentially affecting dosage precision. Always prioritize accurate dosing as prescribed by your healthcare provider.
Who Can Take Disulfiram?
Disulfiram is generally suitable for adults – typically those over the age of 18 – who have been diagnosed with alcohol dependence and are actively motivated to maintain sobriety. It’s used for both men and women, but careful consideration is needed in certain populations. For example, individuals with severe heart disease, liver problems, or kidney impairment may not be suitable candidates due to increased risk of adverse effects.
Extra caution is advised for elderly patients as they might be more sensitive to the medication’s side effects. Disulfiram is absolutely contraindicated during pregnancy and breastfeeding, as it can pose significant risks to the developing fetus or infant. Women of childbearing potential should use effective contraception while taking disulfiram and for a period after stopping treatment.
Individuals with a history of psychosis or severe depression also require careful evaluation before starting disulfiram, as the medication could potentially exacerbate these conditions. A thorough medical assessment is essential to determine if disulfiram is appropriate and safe for each individual patient.
How To Take Disulfiram Generic
Taking disulfiram correctly is paramount to its effectiveness and safety. Always follow your doctor’s instructions meticulously. The tablets should be swallowed whole with a full glass of water, ideally in the morning to ensure consistent coverage throughout the day. It doesn’t necessarily need to be taken with food, but taking it with food can sometimes help minimize potential stomach upset.
Consistency is key; missing doses can reduce the deterrent effect and increase the risk of relapse. If you do miss a dose, take it as soon as you remember unless it’s almost time for your next scheduled dose – in that case, skip the missed dose and continue with your regular schedule. Never double up on doses to compensate for a missed one.
The duration of treatment varies depending on individual circumstances and response to therapy. It’s typically continued for several months or even years under close medical supervision. It’s vital to inform all healthcare providers – including dentists – that you are taking disulfiram before undergoing any procedures, as it can interact with certain anesthetics and other medications.
How Does Disulfiram Work?
Disulfiram works by disrupting the normal metabolism of alcohol in the body. Normally, when we consume alcohol, an enzyme called aldehyde dehydrogenase breaks down acetaldehyde – a toxic byproduct of alcohol metabolism – into acetate, which is then further processed. Disulfiram blocks this enzyme, causing acetaldehyde to accumulate in the bloodstream.
This buildup of acetaldehyde leads to a cascade of unpleasant symptoms if alcohol is consumed. These can include flushing of the face and neck, severe headache, nausea, vomiting, chest pain, dizziness, confusion, and even difficulty breathing. The severity of these reactions depends on the amount of alcohol consumed and individual sensitivity.
Essentially, disulfiram creates an aversion to alcohol by making drinking a profoundly unpleasant experience. It doesn’t eliminate the desire for alcohol, but it provides a powerful deterrent that can help individuals maintain abstinence. Think of it as a built-in consequence system, reinforcing the commitment to sobriety.
Contraindications – Who Should Avoid Disulfiram?
There are several conditions and situations where disulfiram is strictly contraindicated – meaning it should never be used. These include severe heart disease, liver damage, kidney impairment, psychosis, severe depression, pregnancy, breastfeeding, and a history of hypersensitivity to disulfiram or any of its ingredients.
Individuals with certain medical conditions, such as diabetes, thyroid problems, or epilepsy, may also need extra caution and close monitoring while taking disulfiram. It’s crucial to disclose your complete medical history to your doctor before starting treatment. Furthermore, anyone currently experiencing alcohol intoxication should not begin disulfiram therapy until they are fully sober.
Combining disulfiram with certain medications is also dangerous. This includes metronidazole (an antibiotic), isoniazid (used for tuberculosis), and some other drugs that can interact with disulfiram to produce similar adverse reactions as drinking alcohol. Always provide your doctor with a comprehensive list of all medications you are taking, including over-the-counter drugs and herbal supplements.
Interactions – What To Be Aware Of
Disulfiram can interact with a surprising number of substances, potentially leading to dangerous consequences. The most critical interaction is, of course, with alcohol itself. Even small amounts of alcohol – found in some cough syrups, mouthwashes, or even certain foods – can trigger the disulfiram-alcohol reaction.
Beyond alcohol, avoid taking disulfiram concurrently with metronidazole, as this combination can cause a severe and potentially life-threatening reaction similar to drinking alcohol. Isoniazid, another medication used for tuberculosis, also carries a significant risk of interaction.
Be cautious when using topical products containing alcohol, such as aftershave lotions or hair tonics, as they can be absorbed through the skin and trigger a reaction. Even certain fruit juices – like prune juice – may contain enough alcohol to cause problems in sensitive individuals. Always read labels carefully and consult with your doctor or pharmacist if you have any concerns about potential interactions.
Side Effects – What To Expect
Like all medications, disulfiram can cause side effects. Common side effects are generally mild and include metallic taste in the mouth, nausea, vomiting, diarrhea, headache, fatigue, and skin rash. These symptoms often subside with continued use as your body adjusts to the medication. However, if they persist or become bothersome, consult your doctor.
Less common but more serious side effects can include liver problems (jaundice, dark urine), peripheral neuropathy (numbness or tingling in hands and feet), and allergic reactions (hives, swelling). Seek immediate medical attention if you experience any of these symptoms.
Rarely, disulfiram can cause severe psychiatric disturbances, such as psychosis or depression. If you notice any changes in your mood or behavior, contact your doctor immediately. It’s important to remember that everyone reacts differently to medication, and the severity of side effects can vary significantly from person to person.
Overdose Risks – What To Do
An overdose of disulfiram itself is rare, as it doesn’t have a narrow therapeutic window like some other medications. However, combining disulfiram with alcohol constitutes a form of overdose and can be extremely dangerous. Symptoms of a disulfiram-alcohol reaction include flushing, headache, nausea, vomiting, chest pain, dizziness, confusion, difficulty breathing, and even cardiac arrest.
If you suspect someone has experienced a disulfiram-alcohol reaction, call emergency services (999) immediately. Do not attempt to induce vomiting unless instructed by a medical professional. Provide as much information as possible about the amount of alcohol consumed and the dosage of disulfiram taken.
Even without alcohol, very high doses of disulfiram can cause serious side effects like liver damage or neurological problems. If you suspect an overdose, seek immediate medical attention at your nearest emergency room. Prevention is key – always store disulfiram securely out of reach of children and ensure that individuals taking the medication understand the risks associated with alcohol consumption.
Price & Availability
The price of disulfiram varies depending on dosage strength, quantity purchased, and whether you obtain it from a retail pharmacy or an online provider. Generally, generic disulfiram is relatively affordable compared to many other prescription medications. A typical month’s supply (e.g., 60 tablets of 200mg) might cost between £10-£30 depending on the source. You can find more information and purchase options at Disulfiram at medicade.co.uk.
Availability is typically through a prescription from your doctor. However, online pharmacies like https://medicade.co.uk/ offer convenient access to disulfiram after completing an online consultation with a qualified healthcare professional. Online prices can sometimes be more competitive than those at traditional brick-and-mortar pharmacies.
Factors influencing price include the brand (generic vs. branded), the pharmacy’s pricing policies, and any applicable discounts or insurance coverage. It’s always wise to compare prices from different sources before making a purchase.
Buying Drugs Without Prescription Info (UK)
In the United Kingdom, disulfiram is classified as a prescription-only medicine (POM). This means it cannot be legally purchased over the counter without a valid prescription issued by a qualified doctor or other authorized prescriber. However, online pharmacies like https://medicade.co.uk/ provide a legal and convenient way to obtain disulfiram after completing an online medical consultation.
These consultations are conducted by registered healthcare professionals who assess your suitability for the medication and issue a prescription if appropriate. This process ensures that you receive safe and effective treatment under proper medical supervision. Be wary of websites offering disulfiram without a prescription, as these may be selling counterfeit or substandard products, posing serious health risks.

Alternatives to Disulfiram
While disulfiram can be a valuable tool for some individuals, it’s not the only option available for managing alcohol dependence. Several pharmaceutical alternatives exist, including naltrexone and acamprosate. Naltrexone blocks the euphoric effects of alcohol, reducing cravings, while acamprosate helps restore chemical balance in the brain disrupted by chronic alcohol use.
For those seeking non-pharmacological approaches, various therapies and support groups can be highly effective. Cognitive Behavioral Therapy (CBT) helps individuals identify and change thought patterns and behaviors that contribute to drinking. Motivational Interviewing (MI) focuses on enhancing intrinsic motivation for change.
Support groups like Alcoholics Anonymous (AA) provide a safe and supportive environment where individuals can share their experiences, learn from others, and build a network of recovery support. The best approach often involves a combination of medication and therapy tailored to the individual’s specific needs and preferences.
Precautions – Important Considerations
Before starting disulfiram, it’s crucial to inform your doctor about all medical conditions you have, including heart disease, liver problems, kidney impairment, diabetes, thyroid disorders, epilepsy, or mental health issues. Also, disclose any medications you are taking, including over-the-counter drugs and herbal supplements.
Avoid alcohol in all forms while taking disulfiram – even small amounts can trigger a reaction. Be mindful of hidden sources of alcohol in foods, beverages, and topical products. Store disulfiram securely out of reach of children and pets. Follow your doctor’s instructions regarding dosage and duration of treatment.
Regular liver function tests may be necessary while taking disulfiram to monitor for potential side effects. If you experience any unusual symptoms, such as jaundice, dark urine, or abdominal pain, seek medical attention immediately.
