Management of Hypertension and Tachycardia in Alcohol Withdrawal

Introduction to Benzodiazepine Therapy

The American College of Physicians recommends benzodiazepines as the primary treatment for alcohol withdrawal syndrome, including hypertension and tachycardia, due to their ability to alleviate withdrawal discomfort and prevent life-threatening complications 1, 2
Benzodiazepines directly treat the underlying pathophysiology causing the hypertension and tachycardia in alcohol withdrawal patients, which represents autonomic instability that begins 6-24 hours after cessation and peaks at 3-5 days 3

The American Society of Addiction Medicine recommends initiating benzodiazepine therapy immediately for CIWA score ≥8 with hypertension/tachycardia, using a symptom-triggered regimen rather than fixed-dose scheduling 4
For patients without liver dysfunction, the recommended treatment is long-acting benzodiazepines like diazepam 10 mg orally every 3-4 hours or chlordiazepoxide 50-100 mg initially, then 25-100 mg every 4-6 hours as needed 3, 4
For patients with hepatic dysfunction or elderly patients, the recommended treatment is lorazepam 6-12 mg/day due to safer pharmacokinetics 3, 4

The National Institute on Alcohol Abuse and Alcoholism recommends thiamine supplementation for all patients, with 100-500 mg IV immediately before any glucose-containing fluids to prevent Wernicke encephalopathy, and continued thiamine 100-300 mg/day for 2-3 months following resolution of withdrawal symptoms 3, 4

The American College of Emergency Physicians recommends not treating hypertension and tachycardia with antihypertensives or beta-blockers as primary therapy, as these vital sign abnormalities will resolve when the underlying withdrawal is adequately treated with benzodiazepines 1, 2
The Substance Abuse and Mental Health Services Administration recommends not continuing benzodiazepines beyond 10-14 days due to abuse potential, and not using antipsychotics as stand-alone medications, but rather as an adjunct to benzodiazepines in severe withdrawal delirium 1, 2, 3
