Management of Anxiety in Acutely Intoxicated Patients

Pharmacological Management

Benzodiazepines are the treatment of choice for anxiety in patients who have been drinking, as they are the gold standard for managing alcohol-related symptoms including acute agitation and anxiety during alcohol intoxication or withdrawal, according to the American Association for the Study of Liver Diseases 1
The selection of specific benzodiazepine depends on clinical context, with long-acting benzodiazepines (diazepam, chlordiazepoxide) providing superior protection against progression to seizures and delirium tremens, making them preferred for most patients with significant alcohol exposure 1
Short-acting benzodiazepines (lorazepam, oxazepam) are safer alternatives for elderly patients or those with known hepatic dysfunction, as they avoid drug accumulation, as recommended by the American College of Clinical Pharmacology 1

Determine whether anxiety is primary anxiety requiring anxiolytic treatment, or early alcohol withdrawal syndrome (AWS) requiring benzodiazepine-based withdrawal management, with key distinguishing features including time since last drink, presence of tremor, hyperreflexia, elevated blood pressure/pulse, sweating, and history of alcohol dependence 1
Time since last drink (AWS typically develops 6-24 hours after cessation) is an important factor in determining the appropriate treatment approach, according to the American Society of Addiction Medicine 1

Limit benzodiazepine treatment to 7-14 days maximum to minimize dependence risk, as prolonged use beyond this timeframe substantially increases the risk of developing benzodiazepine dependence, as recommended by the National Institute on Alcohol Abuse and Alcoholism 2
Monitor for resolution of anxiety symptoms, development of withdrawal signs (using the CIWA-Ar scale if withdrawal is suspected), and vital sign stability, according to the American Academy of Emergency Medicine 2

Provide thiamine supplementation (100-300 mg/day) to all patients with significant alcohol exposure to prevent Wernicke's encephalopathy, regardless of whether they are experiencing withdrawal, as recommended by the American College of Physicians 2
If the patient has a documented independent anxiety disorder (not alcohol-induced), this will require specific treatment after complete detoxification, as concurrent anxiety disorders may disappear once alcohol is discontinued, according to the American Psychiatric Association 1
