Alcohol withdrawal can be fatal. Unlike opioid withdrawal (uncomfortable but rarely deadly), severe alcohol withdrawal (delirium tremens) carries 5–15% mortality without treatment. Benzodiazepines save lives.

Alcohol Withdrawal Timeline

Timeframe After Last DrinkSymptomsSeverity
6–24 hoursAnxiety, tremors, diaphoresis, tachycardia, hypertension, insomnia, nauseaMild to moderate
12–48 hoursAlcohol withdrawal seizures (generalized tonic-clonic)HIGH RISK WINDOW
24–72 hoursHallucinations (auditory/visual/tactile) — patient may know these are not realModerate to severe
48–96 hoursDelirium tremens (DTs): autonomic instability, severe agitation, confusion, high feverLIFE-THREATENING
Ask last drink time on admission. Every patient admitted for any reason should be screened for alcohol use — withdrawal can occur unexpectedly in admitted patients who have not disclosed alcohol use.

CIWA-Ar Assessment Scale

The Clinical Institute Withdrawal Assessment for Alcohol — Revised (CIWA-Ar) is a 10-item scale scored 0–67.

ItemScore RangeWhat to Assess
Nausea/Vomiting0–70=none, 4=dry heaves, 7=constant vomiting
Tremor0–70=none, 4=moderate w/ arms extended, 7=severe even at rest
Paroxysmal Sweats0–70=none, 4=beads on forehead, 7=drenching sweats
Anxiety0–70=none, 4=moderate (guarded), 7=acute panic
Agitation0–70=none, 4=moderately fidgety, 7=pacing or thrashing
Tactile Disturbances0–7Itching, burning, formication (bugs crawling sensation)
Auditory Disturbances0–7Sounds seem too harsh, or actual hallucinations
Visual Disturbances0–7Photophobia, blurry vision, visual hallucinations
Headache0–7Severity of headache
Orientation0–40=oriented, 4=oriented to person only

CIWA Score Interpretation

ScoreSeverityTypical Action
<10MildMonitor q4–8h; oral lorazepam or chlordiazepoxide per protocol
10–19ModerateMedicate; assess q2–4h; closely monitor
≥20SevereIV benzodiazepines; possible ICU; frequent reassessment

Delirium Tremens (DTs)

Delirium tremens = medical emergency. Notify MD immediately. Patient needs ICU-level monitoring and IV benzodiazepine therapy.

Risk Factors for Severe Withdrawal

Benzodiazepine Protocol

Benzodiazepines are the first-line treatment for alcohol withdrawal. They cross-react with GABA receptors and reduce the excitatory state that causes seizures and DTs.
DrugRouteTypical DoseNotes
Lorazepam (Ativan)IV/IM/PO2–4 mg q1h PRN (IV) based on CIWAPreferred in liver disease; shorter acting
Diazepam (Valium)IV/PO5–10 mg q1h PRN IVLong-acting; self-tapering; use caution in liver disease
Chlordiazepoxide (Librium)PO25–100 mg q4–6h per fixed-schedule protocolOral only; commonly used for mild-moderate withdrawal
Symptom-triggered vs fixed-schedule dosing: CIWA-guided dosing (symptom-triggered) uses LESS medication overall and is preferred when nursing can assess frequently. Fixed-schedule dosing is used when assessment is unreliable (e.g., cognitive impairment).

Benzodiazepine Safety Monitoring

Thiamine & Wernicke's Encephalopathy

NEVER give glucose before thiamine in a known or suspected alcoholic patient. Giving glucose depletes the remaining thiamine and can precipitate Wernicke's encephalopathy.

Thiamine Administration

Wernicke's Encephalopathy — Classic Triad

If untreated, Wernicke's can progress to Korsakoff psychosis — permanent anterograde amnesia and confabulation. Treat immediately with high-dose thiamine (500 mg IV TID) if suspected.
