In any Intensive Outpatient Program (IOP), therapy sessions are at least three hours a day, three days per week. Physicians, psychologists, nurses, and other healthcare professionals administer treatment. IOP programs are more cost-effective than a residential recovery program, but they all share the same goal of sobriety and relapse prevention. Not all people who misuse substances or alcohol are considered addicted, but they may be at risk of becoming addicted. These Outpatient programs can help them before it’s too late.
