Disulfiram is used to treat chronic alcoholism. It causes unpleasant effects when even small amounts of alcohol are consumed. These effects include flushing of the face, headache, nausea, vomiting, chest pain, weakness, blurred vision, mental confusion, sweating, choking, breathing difficulty, and anxiety. These effects begin about 10 minutes after alcohol enters the body and last for 1 hour or more. Disulfiram is not a cure for alcoholism but discourages drinking.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Dosage Of Disulfiram
Disulfiram comes in tablets to take by mouth. It should be taken once a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take disulfiram exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
If you cannot swallow the tablets, crush them and mix the medication with water, coffee, tea, milk, soft drink, or fruit juice.
Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your response to disulfiram.
Always carry an identification card stating that you are taking disulfiram and indicating the doctor or institution to be contacted in an emergency. If you need an identification card, ask your pharmacist or doctor how to get one.
Do not come in contact with or breathe the fumes of paint, paint thinner, varnish, shellac, and other products containing alcohol. Exercise caution when applying alcohol-containing products (e.g., aftershave lotions, colognes, and rubbing alcohol) to your skin. These products, in combination with disulfiram, may cause headaches, nausea, local redness, or itching. Before using an alcohol-containing product, test it by applying some to a small area of your skin for 1-2 hours. If no redness, itching, or unwanted effects occur, you can use the product safely.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
