Alcohol etoxification, or detox, for individuals with alcohol dependence, is the abrupt cessation of alcohol intake coupled with the substitution of alcohol with cross-tolerant drugs that have similar effects in order to prevent alcohol withdrawal. Detoxification may or may not be necessary depending upon an individual's age, medical status, and history of alcohol intake. For example, a young man who binge drinks and seeks treatment one week after his last use of alcohol may not require detoxification before beginning treatment for alcoholism. Benzodiazepines are the most common family of drugs used for this, followed by barbiturates.
