The typical length of stay at an alcohol rehabilitation program is 28 to 30 days, according to the Hazelden Betty Ford Foundation. However, treatment can be shorter or longer, depending on the patient.
Some alcohol treatment programs can last as long as 60 to 90 days, states the Hazelden Betty Ford Foundation. Withdrawing from alcohol can lead to dangerous side effects, such as a life-threatening condition called delirium tremens, or DTs, according to WebMD. Symptoms of DTs include hallucinations, confusion, severe anxiety and seizures. Not everyone requires inpatient treatment for alcohol withdrawal, although people with a history of severe withdrawal or who have attempted to stop drinking multiple times may require inpatient treatment.
