โ ๏ธ Alcohol Withdrawal (Delirium Tremens, DTs) typically develops 48โ72 hours after cessation of heavy drinking.
๐ Always ask when the last drink was consumed.
๐ Prevent DTs with long-acting benzodiazepines.
| ๐ 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 2โ4 mg IV/IM.
- CT head if concern about head trauma or confusion. Add PPI and antiemetics if required.

๐ Alcohol Withdrawal Scale (AWS)
- Somatic (0โ3): pulse, diastolic BP, temperature, respiratory rate, sweating, tremor.
- Mental (0โ4): agitation, contact, orientation, hallucinations, anxiety.
- Scoring:
- <5 = Mild withdrawal
- 6โ9 = Moderate withdrawal
- >9 = Severe withdrawal
๐งฎ CIWA-Ar Scale
The CIWA-Ar (Clinical Institute Withdrawal Assessment for Alcohol Scale, Revised) guides benzodiazepine therapy.
Max score = 67. Each item is rated 0โ7 (except orientation 0โ4).
- 0โ8: Minimal withdrawal โ usually no meds
- 9โ14: Mild โ consider benzodiazepines
- 15โ20: Moderate โ treatment required
- >20: Severe โ frequent dosing ยฑ ICU monitoring
๐ CIWA-Ar Items
- Anxiety
- Agitation
- Auditory disturbances
- Orientation/sensorium
- Paroxysmal sweats
- Tactile disturbances
- Tremor
- Visual disturbances
- Headache
- Nausea & vomiting
๐ก PRN benzodiazepines if CIWA-Ar โฅ8 (symptom-triggered) or โฅ15 (if on reducing regime).
๐งช Neurochemistry
- Alcohol is a CNS depressant acting on GABA and NMDA receptors.
- Chronic use โ thiamine depletion, essential for carbohydrate metabolism.
- Withdrawal = excess glutamate activity, excitotoxicity & oxidative stress.
๐ Management
- Supportive care: calm, well-lit environment, fluids, nutrition, thiamine.
- IV Pabrinex: 2 pairs stat, then TDS ร 5 days (always before glucose) โ prevents Wernicke-Korsakoff syndrome.
- Benzodiazepines:
- Chlordiazepoxide 20โ40 mg PO q6โ8h โ taper 3โ5 days.
- Diazepam 10 mg PO q8h ร 24h โ then reduce.
- Lorazepam 2โ4 mg IM if unable to take orally.
- CIWA-Ar monitoring: reassess q1โ4h and titrate dose.
- โ Avoid haloperidol โ lowers seizure threshold.
โก Risk Factors for Severe Withdrawal
- High alcohol intake (>15 units/day)
- History of seizures/DTs
- Comorbid psychiatric or medical illness
๐ Investigations
- FBC, U&E, LFTs, CRP, Ca, Mg, glucose, coagulation profile
- CT head if altered mental status persists or head trauma suspected
