Yes, Alcohol Withdrawal Causes These Symptoms

Alcohol withdrawal syndrome directly causes anxiety, paranoia, vomiting, and tachycardia through autonomic nervous system overactivity that begins 6-24 hours after the last drink. 1, 2

Clinical Presentation and Timeline

  • Anxiety and autonomic hyperactivity (including tachycardia) are hallmark features of alcohol withdrawal syndrome, occurring within 6-24 hours after cessation and representing overactivity of the central and autonomic nervous systems 1, 3

  • Vomiting is a common gastrointestinal manifestation of the autonomic instability that characterizes alcohol withdrawal 1, 2

  • Paranoia occurs as part of the spectrum of severe alcohol withdrawal complications, particularly when withdrawal progresses toward delirium tremens 4, 5

Symptom Progression and Severity

  • Symptoms typically peak at 3-5 days after cessation and generally resolve spontaneously within one week 1, 6

  • The presence of anxiety, agitation, vomiting, and tachycardia indicates at minimum moderate alcohol withdrawal syndrome requiring treatment 1, 2

  • More severe manifestations can include hallucinations, seizures, and delirium tremens (which begins 48-72 hours after cessation and includes confusion, paranoia, and hallucinations) 1, 5, 7

Critical Assessment Points

  • Vital signs monitoring is essential to assess the degree of autonomic instability—look specifically for tachycardia, hypertension, fever, and excessive sweating 1, 2

  • CIWA-Ar scores >8 indicate moderate withdrawal requiring treatment, while scores ≥15 indicate severe withdrawal 2

  • Evaluate for dangerous complications including dehydration, electrolyte imbalance (especially magnesium), infection, gastrointestinal bleeding, pancreatitis, hepatic encephalopathy, and renal failure 1, 2

Immediate Management Priorities

  • Benzodiazepines are first-line therapy for moderate to severe symptoms—they are the only proven treatment to prevent seizures and reduce mortality from delirium tremens 1, 2, 6

  • Thiamine 100-300 mg/day must be administered BEFORE any glucose-containing IV fluids to prevent precipitating acute Wernicke encephalopathy 1, 2, 8

  • For moderate to severe withdrawal: initiate chlordiazepoxide 50-100 mg orally, followed by 25-100 mg every 4-6 hours as needed (maximum 300 mg in first 24 hours), or diazepam 10 mg orally 3-4 times daily 1, 2, 8

  • In patients with hepatic dysfunction, elderly patients, or respiratory compromise, switch to lorazepam 6-12 mg/day instead of long-acting agents 1, 2, 8

Common Pitfall to Avoid

  • Do not dismiss paranoia as a psychiatric issue unrelated to withdrawal—paranoia is explicitly listed as a severe adverse reaction associated with alcohol withdrawal and benzodiazepine withdrawal, and can progress to psychosis and suicidal behavior if untreated 4, 5
