4 Introduction and Aim In the UK, it is estimated that 24% of adults drink in a hazardous or harmful way that may put them at risk of acute alcohol withdrawal, seizures or delirium tremens 1. Successful detoxification will reduce the risk of these complications, although prescription regimens are highly variable and do not always take into account the severity of alcohol withdrawal. Based on NICE guidance, these protocol guidelines were written 1. Patients with acute alcohol withdrawal of patients at risk of developing alcohol withdrawal seizures or delirium tremens, should be offered admission to hospital for medically assisted alcohol withdrawal 1. Withdrawal severity scoring tools, such as the Severity of Alcohol Dependence Questionnaire (SADQ) and Clinical Institute Withdrawal Assessment Alcohol revised (CIWA-Ar) score should be used to gauge the severity of withdrawal and treatment should be individualised 1,2,3. This allows an objective measure of severity of alcohol withdrawal to be recorded and an appropriate regimen prescribed. In the UK, benzodiazepines are the most commonly used medications for acute alcohol withdrawal. Chlordiezopoxide and diazepam have UK marketing authorisation for this indication 1. The recommended dose of chlordiazopoxide for acute alcohol withdrawal in moderate to severe dependence should be 10 to 50mg in four daily doses 4. The protocol herein reflects this. 4

5 Withdrawal assessment and protocol 1. Individualise the alcohol withdrawal regimen to the patient. 2. The SADQ should be used FIRST to determine the appropriate withdrawal regimen (see below). 3. With all scheduled regimens, as required chlordiazepoxide 10-20mg must be prescribed and administered as per clinical need. 4. Ensure that Pabrinex is prescribed and administered. One pair of Pabrinex IVHP ampoules IV TDS for at least 1 day for known or suspected chronic alcohol misuser. Two pairs of Pabrinex IVHP ampoules IV TDS for 3-7 days for patients displaying symptoms of Wernicke s Encephalopathy (WE). If Pabrinex is not available/cannot be administered, prescribe Thiamine 100mg TDS PO and Vitamin B compound strong 2 tablets TDS. 5. Review the drug chart and ensure that no other additional benzodiazepines are prescribed. 6. The modified CIWA-Ar score sheet should then be used twice daily (by nurses or doctors on ward rounds) to assess whether further as required chlordiazepoxide is required. 7. If, on day 5, the patient is still requiring as required doses of chlordiazepoxide, their regimen should be reviewed. 8. If the patient becomes drowsy then medical assistance should be requested and no further doses of chlordiazepoxide be given. 9. Please refer patient to the Substance Misuse Liaison Team at the earliest opportunity by calling or
