Recovering users who have completed OxyContin detox are encouraged to enter an inpatient, residential, or outpatient treatment program where they can focus on their addiction. Outpatient treatment offers the most flexibility while inpatient and residential likely require a 30-day or longer stay at the treatment facility.Research shows that at least three months or more are needed to treat drug addiction.  A longer stay gives residential clients a chance to develop the life skills and strategies they need to live OxyContin-free. They can benefit from cognitive behavioral therapy, dialectical behavioral therapy, mindfulness, and other therapies and approaches that support their path to recovery.
