What is OUD (opioid use disorder)?

OUD, opioid use disorder, is a medical condition characterized by a problematic pattern of opioid use, leading to significant impairment or distress. OUD can involve the use of prescription opioids, such as oxycodone or hydrocodone, or illegal opioids, such as heroin or illicitly manufactured fentanyl.


OUD is a critical public health issue, and its effective treatment often involves a combination of medications, behavioral therapies, and support services.
