USES Disulfiram is used as an aid to treat alcoholics who are strongly motivated to remain sober. Disulfiram blocks the breakdown of alcohol by the body, leading to an accumulation of the chemical acetaldehyde in the bloodstream. Buildup of acetaldehyde in the body can lead to a severe and very unpleasant reaction after alcohol consumption. Alcohol must, therefore, be avoided to prevent this reaction. TREATMENT Disulfiram can be taken either on an empty stomach or with food or milk (as directed by your doctor). The tablets can also be crushed and mixed with beverages (nonalcoholic). If you miss a dose of this medication, take the missed dose as soon as possible, unless it is almost time for the next dose. In that case, do not take the missed dose at all; just return to your regular dosing schedule. Do not double the next dose. SIDE EFFECTS Minor. Drowsiness, fatigue, headache, metallic or garlic-like aftertaste, and restlessness. These side effects should disappear as your body adjusts to the medication. Major. Tell your doctor about any side effects that are persistent or particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about blurred vision, impotence, joint pain, mental disorders, skin rash, tingling sensations, or yellowing of the eyes or skin. INTERACTIONS Disulfiram interacts with several other types of medications: 1. It can increase the blood levels and side effects of diazepam, chlordiazepoxide, phenytoin, and oral anticoagulants (blood thinners, such as warfarin). 2. Concurrent use of disulfiram with isoniazid, antidepressants, metronidazole, or marijuana can lead to severe reactions. BE SURE TO TELL YOUR DOCTOR about any medications you are currently taking, especially any of those listed above. Also, be sure to tell your doctor if you use marijuana. WARNINGS * Tell your doctor about unusual or allergic reactions you have had to any medications, especially to disulfiram, rubber, pesticides, or fungicides. * Before starting to take this medication, be sure to tell your doctor if you have ever had brain damage, dermatitis, diabetes mellitus, epilepsy, heart disease, kidney disease, liver disease, mental disorders, or thyroid disease. * It is important not to drink or to use any alcohol-containing preparations, medications, or foods (including beer, elixirs, tonics, wine, liquor, vinegar, sauces, after-shave lotions, liniments, or colognes) while taking this medication. Be sure to check the labels on any over-the-counter (nonprescription) products for their alcohol content, especially cough syrups, mouthwashes, and gargles. * It is important that you understand the serious nature of the disulfiram-alcohol reaction. If you take disulfiram within 12 hours after ingesting alcohol or drink alcohol within two weeks after your last dose of disulfiram, you may experience blurred vision, chest pain, confusion, dizziness, fainting, flushing, headache, nausea, pounding heartbeat, sweating, vomiting, or weakness. The reaction usually occurs within five to ten minutes of drinking alcohol and can last from half an hour to two hours, depending on the dose of disulfiram and the quantity of alcohol ingested. * If this drug makes you drowsy, do not take part in any activity that requires alertness, such as driving a car or operating potentially dangerous machinery. Also be careful when going up and down stairs. * Be sure to tell your doctor if you are pregnant. Birth defects have been reported in both animals and humans whose mothers received disulfiram during pregnancy. It must also be kept in mind that alcohol, even in small amounts, can cause a variety of birth defects when ingested during pregnancy. Also, tell your doctor if you are breast-feeding an infant. It is not known if disulfiram passes into breast milk. ---------------- The material contained here is "FOR INFORMATION ONLY" and should not replace the counsel and advice of your personal physician.
