Depending on the patient's individual needs, opioid addiction treatment can take many different forms, take place in a variety of settings, and last for a variety of lengths. The use of medications and combining medications with behavioral therapy are evidence-based approaches to treating opioid addiction. It is more likely that a recovery plan that includes medication for opioid addiction will be successful. Drugs that treat opioid addiction can reduce withdrawal symptoms, relieve cravings, and normalize brain chemistry in some cases. In addition to the medical decision to include medication in recovery, there is substantial evidence that medications support successful recovery.
