Disulfiram-alcohol reaction (DAR) is the effect of the interaction in the human body of alcohol drunk with disulfiram or some mushrooms.[1][2] The DAR is key to disulfiram therapy that is widely used for alcohol-aversive treatment and management of other addictions (e.g. cocaine[3][4] use).[5][6] Once disulfiram-treated patients take alcohol, even in small doses, they experience strong unpleasant sensations (flush, nausea, lightheadedness, headache, sweating, vomiting, and vertigo).[7]
Disulfiram has been used to treat alcoholism since 1948 after its accidental discovery in Denmark.[8][9][10]
Pharmacology
DAR symptoms usually begin within 5–15 minutes of the ingestion of alcohol by a patient who has taken disulfiram 3–12 hours before.[8]
Increased
The intensity of a patient's experience of DAR varies with race of the subject.[16]
It has long been known that disulfiram can cause hepatitis and can be fatal (1 case per 30,000 patients), although due to dosage reductions in recent decades, such cases are extremely rare.[17] Death, however, from the reaction itself without significant liver damage is also possible as an atypical case.[18][19]
Unintended initiations
DAR can occur from skin contact of a disulfiram-treated patient with alcohol-containing skin care products such as colognes, sunscreen lotions, aftershave lotions, and alcohol-based tar gels,[20] but a significant toxic effect does not appear to be achieved in this way.[21] During the COVID-19 pandemic, there were also cases of DAR initiation due to the use of alcohol-based hand sanitizers.[22]
Some mushrooms contain substances that, when combined with alcohol, cause DAR.
