Alcohol detoxification at home without the supervision of a medical professional can be dangerous as it involves withdrawal symptoms which can be severe and unpredictable. Thus, it is most effective when done by a medical professional.
The benefits of medical detoxification can include a safe and structured environment, medical stability, peer support, family support, therapeutic intervention, relapse prevention, and long term treatment.
Withdrawal symptoms may include anxiety, sweating, tremors, rapid heart rate, nausea, irritability, etc. In severe cases, the symptoms may include seizures, hallucinations, high body temperature, paranoia, illusions, etc.
