What happens

Medical evaluation, individualized detox protocol, medication administration, vital sign monitoring, nutritional support, and medication adjustment based on symptom severity.

Medications by substance

Alcohol: benzodiazepines for seizure prevention. Opioids: buprenorphine or methadone for withdrawal, or clonidine with comfort meds. Benzos: gradual cross-taper. Stimulants: symptom management only.

Duration

Alcohol: 5-7 days. Opioids: 5-10 days. Benzos: 7-14+ days. Stimulants: 3-7 days for acute symptoms.

Critical point

Detox is medical stabilization, NOT treatment. The therapy, behavioral change, and relapse prevention come after. Detox alone has high relapse rates.

Medications significantly reduce discomfort compared to unmedicated withdrawal. Not pain-free but far more tolerable.
Does insurance cover detox?
Yes. Most plans cover medical detox as a medically necessary procedure.
