[2012]

Recommendation(s)

Supported withdrawal from alcohol should be advised in patients with alcohol dependence, as a precursor to treatment.
Strength of recommendation: STRONG
Quality of evidence: LOW

Benzodiazepines are recommended as front-line medication for the management of alcohol withdrawal in alleviating withdrawal discomfort, and preventing seizures and delirium. Long-acting benzodiazepines are recommended over shorter-acting ones, except in cases of impaired hepatic metabolism (e.g. liver failure, elderly). The dose and duration should be individually determined, according to the severity of withdrawal and the presence of other medical disorders. In general, the duration of benzodiazepines treatment should be limited to the first 3 to 7 days after the cessation of alcohol.
