Defining Outpatient Treatment

Outpatient treatment is a way for people to receive treatment in a less restrictive environment, often working around school or work schedules. It is typically less expensive and more flexible than inpatient care, allows people to stay in treatment for longer periods of time, and can be supportive in helping people adjust to living without using substances. Facilities may provide medications that can reduce cravings and treat mental health disorders as needed. Counseling is done in a combination of individual and group sessions, with family or marital counseling frequently available.1,8 Behavioral therapies are especially beneficial in helping people make positive changes and learn to cope with triggers.7,8,9
