How long does
opioid withdrawal last?
These are broad untreated-withdrawal reference ranges, not instructions for stopping a prescription or starting buprenorphine. Treatment changes the course; sleep, mood and cravings may need attention beyond the acute symptoms.
Shorter-acting opioids, such as heroin
WHO gives a usual onset of 8–24 hours after last use and an acute duration of roughly 4–10 days.
Longer-acting opioids, such as methadone
WHO gives a usual onset of 12–48 hours and an acute duration of roughly 10–20 days.
Fentanyl and mixed drug supplies
Those older reference ranges don’t reliably predict an individual fentanyl course. The product, repeated use and other substances affect assessment.

Get help with
how medication starts.
Starting buprenorphine requires an individual plan. Fentanyl exposure can make that decision more complicated. Tell the prescriber about recent use and previous experiences of sudden, severe withdrawal after medication.
Don’t use this page to choose a dose or a start time.
A medical appointment can address withdrawal and ongoing opioid use disorder treatment together. You don’t need to prove you can get through withdrawal without help.
Medication access.
Follow-up.
Overdose prevention.
The follow-up
When is the next visit, and who do you contact about symptoms or a missed appointment?
Access to medication
Which pharmacy or program is involved? What could delay access, and whom should you call?
Overdose prevention
Ask about naloxone and how the people around you can respond. Returning to opioid use after tolerance falls increases overdose risk.
Daily life
Getting to work and the appointment, paying for transport and telling family what you need are real parts of making care happen.
Ask what fits
the person.
Methadone, buprenorphine and naltrexone are FDA-approved medications for opioid use disorder. People may know buprenorphine by names such as Suboxone or Sublocade, and injectable naltrexone as Vivitrol.
The medication, setting and follow-up belong in a conversation with a qualified medical provider. I don’t prescribe or change medication. My experience includes thirteen years in opioid treatment and building a medication-supported program.
Get the appointment.
Keep the care connected.
Finding a provider
Look for a suitable opioid treatment program or prescribing practice and clarify its intake process.
Before the visit
Organize the questions, medication information and practical details the provider asks for.
Family understanding
Help the family understand medication-supported recovery and its role in the person’s care.
After the visit
Coordinate appointments, transport, routines and communication with permission. Medication decisions stay with the prescriber.

Questions about
opioid care.
Is fentanyl withdrawal on the same schedule as heroin withdrawal?+
Not reliably. A prescriber needs to assess the person, recent use, symptoms and other drugs involved. A general timeline can’t tell you when it is safe to start buprenorphine.
Is detox enough treatment for opioid use disorder?+
Withdrawal management alone doesn’t address ongoing opioid use disorder. Ask about continuing medication treatment and overdose prevention before discharge. I can help keep the next appointment and practical arrangements from getting lost.
What do MAT and MOUD mean?+
MAT means medication-assisted treatment. MOUD means medications for opioid use disorder. You may hear both terms when discussing opioid care. A provider can explain the medication and the other care included in a particular service.
What medications are used for opioid use disorder?+
FDA-approved medications include methadone, buprenorphine and naltrexone. The right choice and how to start it need an individual medical assessment. I don’t prescribe medication or tell you to change a dose.
Can you help connect opioid medication treatment in Des Moines?+
Yes. I can contact prescribers or opioid treatment programs about intake and appointments. With permission, I can coordinate the practical arrangements and follow-up.
Can you help someone connect with a methadone program?+
Yes. Methadone treatment for opioid use disorder is provided through a certified opioid treatment program. I can help with program contact, intake questions, appointments and the practical requirements of attending.
What if fentanyl or more than one substance is involved?+
Tell the medical provider about all substances, medications and recent use. That information affects safe care. I can help you organize those details and connect with an appropriate provider without giving you a home induction or withdrawal schedule.
Can my family get help understanding medication treatment?+
Yes. We can work through the questions and assumptions around prescribed medication and prepare questions for the clinician. Family support can also address routines, communication and practical follow-through.
