⚠️ Alcohol Withdrawal (Delirium Tremens, DTs) typically develops 48–72 hours after cessation of heavy drinking.
👉 Always ask when the last drink was consumed.
💊 Prevent DTs with long-acting benzodiazepines.
| 🚑 Acute Alcohol Withdrawal Management |
- Provide ABC support and monitor vital signs. Consider ITU if seizures are uncontrolled.
- Administer IV Pabrinex (2 pairs) immediately, then TDS for 2 days.
- Chlordiazepoxide 25 mg TDS PO or Diazepam 10 mg PO 8-hourly, taper based on CIWA-Ar score.
- For seizures: Lorazepam 2–4 mg IV/IM.
- CT head if concern about head trauma or confusion. Add PPI and antiemetics if required.

📊 Alcohol Withdrawal Scale (AWS)
- Somatic (0–3): pulse, diastolic BP, temperature, respiratory rate, sweating, tremor.
- Mental (0–4): agitation, contact, orientation, hallucinations, anxiety.
- Scoring:
- <5 = Mild withdrawal
- 6–9 = Moderate withdrawal
- >9 = Severe withdrawal
🧮 CIWA-Ar Scale
The CIWA-Ar (Clinical Institute Withdrawal Assessment for Alcohol Scale, Revised) guides benzodiazepine therapy.
Max score = 67. Each item is rated 0–7 (except orientation 0–4).
- 0–8: Minimal withdrawal – usually no meds
- 9–14: Mild – consider benzodiazepines
- 15–20: Moderate – treatment required
- >20: Severe – frequent dosing ± ICU monitoring
📝 CIWA-Ar Items
- Anxiety
- Agitation
- Auditory disturbances
- Orientation/sensorium
- Paroxysmal sweats
- Tactile disturbances
- Tremor
- Visual disturbances
- Headache
- Nausea & vomiting
💡 PRN benzodiazepines if CIWA-Ar ≥8 (symptom-triggered) or ≥15 (if on reducing regime).
🧪 Neurochemistry
- Alcohol is a CNS depressant acting on GABA and NMDA receptors.
- Chronic use → thiamine depletion, essential for carbohydrate metabolism.
- Withdrawal = excess glutamate activity, excitotoxicity & oxidative stress.
💊 Management
- Supportive care: calm, well-lit environment, fluids, nutrition, thiamine.
- IV Pabrinex: 2 pairs stat, then TDS × 5 days (always before glucose) → prevents Wernicke-Korsakoff syndrome.
- Benzodiazepines:
- Chlordiazepoxide 20–40 mg PO q6–8h → taper 3–5 days.
- Diazepam 10 mg PO q8h × 24h → then reduce.
- Lorazepam 2–4 mg IM if unable to take orally.
- CIWA-Ar monitoring: reassess q1–4h and titrate dose.
- ❌ Avoid haloperidol – lowers seizure threshold.
⚡ Risk Factors for Severe Withdrawal
- High alcohol intake (>15 units/day)
- History of seizures/DTs
- Comorbid psychiatric or medical illness
🔍 Investigations
- FBC, U&E, LFTs, CRP, Ca, Mg, glucose, coagulation profile
- CT head if altered mental status persists or head trauma suspected
