Before taking the DISULFIRAM, let your doctor know about all your medical conditions, sensitivities, and all medications you are using. Signs of an overdose of DISULFIRAM include feeling or being sick, stomach pain, diarrhoea, drowsiness, mental disorders, tiredness, rapid heartbeat, rapid breathing, high body temperature, low blood pressure, loss of muscle control, high blood sugar, changes in the blood (as seen in blood tests). Certain foods, liquid medicines, remedies, tonics, toiletries, perfumes, and sprays may contain enough alcohol to cause a disulfiram tablet-alcohol reaction. So avoid using any alcohol-containing drugs, hand wash, mouth wash or alcoholic beverages as it may lead to an 'aldehyde reaction'.

Drug-Drug interactions: DISULFIRAM interacts with anti-seizure drugs (phenytoin), anti-asthma drugs (theophylline), blood thinners (warfarin, dicumarol), anti-tuberculosis drugs (rifampicin, isoniazid), sedatives (chlordiazepoxide, diazepam), antipsychotics (pimozide), anti-depressants (amitriptyline), mental health drugs (chlorpromazine), and antimicrobial drugs (metronidazole).

Drug-Food interactions: Avoid taking DISULFIRAM with caffeinated products like chocolate, coffee, energy drinks & tea. The patient is advised to avoid alcoholic beverages or alcohol-containing products/foods (e.g., cough and cold syrups, mouthwash, aftershave, sauces, and vinegar) while taking this medication and for two weeks after stopping the medication.

Drug-Disease interactions: DISULFIRAM is to be avoided in a patient with coronary artery disease, mental disorder, diabetes, underactive thyroid gland, brain seizures, brain damage, kidney disease & liver disease.

• A patient is advised to have a diet that increases serotonin levels which makes a person feel good & involves eating foods high in carbohydrates, especially the complex carbohydrates present in starchy food items like legumes (e.g., beans, lentils and peas), root vegetables (e.g., potatoes and carrots), pasta and bread. Eating such foods in combination with protein in meals will benefit.
• Deficiencies in B-complex vitamins such as thiamine, folate or folic acid, and B12 are common with alcoholism, and inadequate stores of other B vitamins and vitamin C frequently occur. A patient should take supplements and vitamins on consulting a doctor.
• Malnutrition is common during alcohol consumption and is revealed slowly and gradually. The patient becomes tired and develops a weaker immune system—which means they are more susceptible to infections. These problems need to be identified and treated during the recovery process—ideally by a team of healthcare professionals.
• The patient should change his drinking priorities and prefer drinks like apple cider, vanilla shake, mixing juice or lemonade with sparkling water etc.

• DISULFIRAM may interfere with certain laboratory tests (including urine VMA/HVA tests), possibly causing false test results. It is a paramount priority for a patient to enlighten the laboratory personnel and all their doctors to know they use this drug.
• DISULFIRAM should never be given to a patient when they are in a state of alcohol intoxication or without his full knowledge.
• After you stop taking DISULFIRAM, do not drink alcohol for at least seven days as your body needs to start making the enzyme 'acetaldehyde' again. In case, drinking alcohol earlier than this may trigger an 'aldehyde reaction'.
