Detoxification and Withdrawal Management
What to know
Detoxification is medically supervised withdrawal management, not treatment itself. Know CIWA-Ar for alcohol withdrawal and COWS for opioid withdrawal. Understand alcohol withdrawal timeline and delirium tremens (peak 48–96 hours; autonomic instability, hallucinations, confusion - a medical emergency). Treatment: benzodiazepines (first-line), thiamine (prevent Wernicke encephalopathy), folate, magnesium, glucose after thiamine. Opioid withdrawal is rarely fatal but intensely uncomfortable; buprenorphine/naloxone or methadone can manage symptoms, and clonidine/lofexidine address autonomic symptoms. Benzodiazepine withdrawal requires gradual tapering due to seizure risk. Know that detoxification alone has high relapse rates and should be linked to ongoing treatment.
Traps
Questions imply detox equals treatment or that opioid withdrawal is life-threatening (it is generally not; alcohol and benzodiazepine withdrawal are). Watch for items giving glucose before thiamine in at-risk patients (risk of Wernicke). Don't confuse CIWA with COWS. Note that symptom-triggered dosing is often preferred over fixed dosing for alcohol withdrawal.
Rule of thumb
Alcohol and benzodiazepine withdrawal can kill; opioid withdrawal rarely does. For any patient with alcohol use and altered mental status, give thiamine before glucose.
Worked example
A patient with heavy alcohol use presents with confusion; you plan IV glucose. Give thiamine first to prevent Wernicke encephalopathy, then glucose. Concurrently assess with CIWA-Ar and initiate benzodiazepines if indicated.
