Why Is Medical Detox Required for Alcohol?
Alcohol withdrawal is one of the only substance withdrawal syndromes that can be directly fatal. In people with severe alcohol dependence, abrupt cessation can cause seizures within 24–48 hours of last drink, and a condition called delirium tremens (DTs) — characterized by confusion, hallucinations, and cardiovascular instability — in 5–10% of cases. DTs carry a mortality rate of up to 15% without treatment. Medical detox provides the medication management (typically benzodiazepines) and monitoring required to prevent these complications.
What Happens in Alcohol Rehab After Detox?
After medical detox (typically 5–7 days for alcohol), patients transition directly into residential treatment. Alcohol rehab programming includes individual therapy, group sessions, psychoeducation on alcohol use disorder, relapse prevention planning, and, for many patients, integrated dual diagnosis treatment for co-occurring depression or anxiety. Medications like naltrexone or acamprosate can be initiated during or after inpatient treatment to reduce cravings and support long-term abstinence.
