The drug should never be taken in a state of alcohol intoxication. It is unacceptable to prescribe the drug without informing the patient. Relatives of the patient should be instructed by the doctor about the features of the drug.
Disulfiram with extreme caution should be used with the following concomitant diseases: diabetes mellitus, hypothyroidism, epilepsy, chronic and acute nephritis, as well as in patients over the age of 65 years. Data on the hepatotoxicity of the drug, including liver failure, requiring liver transplantation or fatal, have been reported. Severe and sometimes lethal hepatitis caused by disulfiram therapy may develop many months after the drug treatment is completed. The patient should be warned about the need to tell the doctor about all early symptoms of hepatitis, such as fatigue, weakness, malaise, decreased appetite, nausea, vomiting, jaundice, the appearance of dark urine. Every 10-14 days from the start of disulfiram therapy, a patient should conduct a follow-up study of liver function parameters, including general and biochemical blood tests.
Patients receiving
disulfiram should not be exposed to ethylene dibromide and its vapors. Results of studies in rats demonstrated,that inhalational administration of ethylene dibromide with disulfiram increases the development of tumors and mortality in rats. There are no analogous data on the effect of diethyl bromide vapors on patients. Reaction of alcohol and disulfiram interaction:
The patient should be informed of all consequences of alcohol use during disulfiram treatment. The patient should be warned about the inadmissibility of secret consumption of alcohol, as well as alcohol in the composition of food products (sauces), medicines (spir-containing drugs), perfumes. Drinking alcohol simultaneously with disulfiram, even in small amounts, causes reddening of the face, pulsation in the head and neck region, throbbing headache, difficulty breathing, nausea, profuse vomiting, sweating, thirst, chest pain, increased heart rate, shortness of breath, weakness, confusion and loss of consciousness, severe anxiety, dizziness, blurred vision. In severe cases, respiratory depression, cardiovascular insufficiency, convulsions and death may develop.
The intensity of the reaction is individual, but, as a rule, is proportional to the amount of alcohol and disulfiram taken inside. Initial manifestations of the reaction can be noted in persons with increased sensitivity with an increase in the concentration of alcohol to only 5-10 mg in 100 ml of blood. The full development of symptoms develops at an alcohol concentration of 50 mg per 100 ml. blood. At a level of alcohol in the blood from 125 mg to 150 mg per 100 ml, loss of consciousness is noted. The reaction time varies from 30 - 60 min to several hours; in more severe cases - as long as alcohol is detected in the blood.
