Opioid Use Disorder
Opioid use disorder is treatable. Medication may reduce withdrawal and cravings and lower the risk of overdose.
What is opioid use disorder?
Opioid use disorder involves a pattern of opioid use that causes significant problems or distress. It may involve prescription pain medication, heroin, fentanyl, or other opioids. Signs include loss of control, cravings, continued use despite harm, and difficulty meeting responsibilities.
Physical dependence is different: the body may adapt to a prescribed opioid and develop withdrawal if it is stopped. Tolerance and withdrawal during appropriate medical treatment do not, by themselves, establish opioid use disorder.
What makes the pattern dangerous?
Breathing and overdose risk: Opioids may slow or stop breathing. Risk increases with uncertain drug strength, fentanyl exposure, or combination with alcohol, benzodiazepines, and other sedating substances.
Reduced tolerance: Tolerance falls after a period without opioids. Returning to a previously used amount after detoxification, hospitalization, incarceration, or another break may cause overdose. A person does not need to wait for a crisis or another overdose to begin treatment.
How is it assessed?
Use, withdrawal, and health: Your provider asks what you use, how you use it, the timing of the last dose, withdrawal symptoms, past treatment, and overdose history. Pain, sleep, mental health, pregnancy, infections, and other substances may also affect the plan.
Being specific helps the team choose treatment safely. The assessment should lead to care rather than serve as a test of whether someone is sufficiently motivated.
What treatments are available?
Medications for opioid use disorder: Buprenorphine, methadone, and naltrexone are medications used to treat opioid use disorder. Buprenorphine and methadone may reduce cravings and withdrawal. Naltrexone blocks opioid effects and requires an opioid-free period before starting to avoid precipitated withdrawal.
Choosing and starting treatment: The right choice depends on your situation, preferences, and access to care. Starting or changing treatment should be guided by a clinician, especially after fentanyl exposure. Counseling and practical support may help, but access to medication should not depend on completing counseling first.
Why is detoxification alone not enough?
Continuing treatment: Managing withdrawal does not address the ongoing risk of returning to use. Detoxification without continuing medication treatment is associated with higher risk of relapse and overdose. Treatment may be needed long term, and its duration should be based on benefit and safety rather than an arbitrary deadline.
A return to use is a reason to reassess support and treatment. It should not automatically mean losing access to care.
Overdose prevention and next steps
Naloxone and emergency response: Keep naloxone available and make sure people around you know how to use it. If someone is unresponsive or breathing slowly or not at all, call 911, give naloxone if available, and follow the dispatcher’s instructions. Additional doses may be needed. Stay with the person; improvement after naloxone does not remove the need for emergency care.
Ask where medication treatment can begin, what to do about withdrawal or pain, and how to obtain naloxone. Discuss infection screening and other harm-reduction services when relevant. Care can start even while you are still using opioids.
