From the Guidelines
The recommended treatment for managing opioid withdrawal symptoms involves a combination of medications and supportive care, with buprenorphine being the first-line medication due to its partial opioid agonist properties that effectively reduce withdrawal symptoms while minimizing abuse potential. Medication-assisted treatment (MAT) is the gold standard, and buprenorphine (typically 8-24 mg daily) is the preferred choice, as it has been shown to be safe and effective in treating opioid withdrawal, according to a systematic review published in the Annals of Emergency Medicine 1. Methadone (starting at 20-30 mg daily and titrating as needed) is another effective option, particularly for patients with severe opioid use disorder. Clonidine (0.1-0.3 mg every 6-8 hours) can help manage autonomic symptoms like hypertension, sweating, and anxiety. For specific symptom management, loperamide (4 mg initially, then 2 mg after each loose stool) can treat diarrhea, ondansetron (4-8 mg every 8 hours) helps with nausea, and NSAIDs or acetaminophen can address pain and discomfort.
Adequate hydration, nutritional support, and rest are crucial components of care. Withdrawal management should ideally be conducted under medical supervision, as symptoms typically peak within 72 hours and may last 7-10 days for short-acting opioids, or longer for methadone. The initiation of buprenorphine requires that patients must be experiencing opioid withdrawal, and the presence of at least mild withdrawal symptoms should be verified by the administration of a validated opioid withdrawal scale, as recommended by the American Journal of Obstetrics and Gynecology 1.
Some key considerations for buprenorphine initiation include:
- Abstaining from short-acting opioids at least 12-24 hours before induction and long-acting opioids 36-48 hours before induction
- Verifying the presence of at least mild withdrawal symptoms using a validated opioid withdrawal scale
- Starting with a low dose of buprenorphine (2-4 mg) and titrating as needed to manage withdrawal symptoms
- Monitoring patients closely for signs of withdrawal or overdose, and adjusting the treatment plan as needed.
It's also important to note that buprenorphine can precipitate acute opioid withdrawal in patients on full mu agonists, and patients should be in mild opioid withdrawal before restarting buprenorphine therapy, as stated in the Mayo Clinic Proceedings 1. Overall, a comprehensive approach to managing opioid withdrawal symptoms, including medication-assisted treatment and supportive care, can help make the withdrawal process more tolerable and increase the chances of successful transition to long-term recovery.
From the FDA Drug Label
The initial methadone dose should be administered, under supervision, when there are no signs of sedation or intoxication, and the patient shows symptoms of withdrawal. Initially, a single dose of 20 to 30 mg of methadone will often be sufficient to suppress withdrawal symptoms The initial dose should not exceed 30 mg. If same-day dosing adjustments are to be made, the patient should be asked to wait 2 to 4 hours for further evaluation, when peak levels have been reached. An additional 5 to 10 mg of methadone may be provided if withdrawal symptoms have not been suppressed or if symptoms reappear The total daily dose of methadone on the first day of treatment should not ordinarily exceed 40 mg. Dose adjustments should be made over the first week of treatment based on control of withdrawal symptoms at the time of expected peak activity (e.g., 2 to 4 hours after dosing).
The recommended treatment for managing opioid withdrawal symptoms is methadone. The initial dose is typically 20 to 30 mg, which can be adjusted based on the patient's response to treatment. The goal is to suppress withdrawal symptoms while minimizing the risk of overdose. Dose adjustments should be made cautiously, with a maximum total daily dose of 40 mg on the first day of treatment 2. Key considerations include:
- Initial dosing: 20 to 30 mg, under supervision
- Dose adjustment: based on control of withdrawal symptoms, with a maximum increase of 5 to 10 mg
- Total daily dose: not to exceed 40 mg on the first day of treatment
- Monitoring: patients should be closely monitored for signs of sedation, intoxication, and withdrawal symptoms.

Opioid Withdrawal Symptoms and Treatment
Opioid withdrawal symptoms can be managed with various treatments, including buprenorphine. The following points summarize the recommended treatment for managing opioid withdrawal symptoms:
- Buprenorphine is a partial mu-opioid receptor agonist with high affinity and low intrinsic activity, making it an optimal treatment alternative for patients presenting with opioid withdrawal 3.
- Buprenorphine is more effective than clonidine or lofexidine for managing opioid withdrawal in terms of severity of withdrawal, duration of withdrawal treatment, and the likelihood of treatment completion 4, 5, 6.
- Buprenorphine and methadone appear to be equally effective, but data are limited, and withdrawal symptoms may resolve more quickly with buprenorphine 4, 5, 6.
- A multimodal medication-assisted treatment (MAT) plan involving pharmacologic treatment, as well as counseling and behavioral therapy, is essential to maintaining opioid remission 3.
Buprenorphine Administration
Buprenorphine can be administered in various forms, including:
- Sublingual film or tablet
- Transbuccal
- Transdermal
- Subdermal (implant)
- Subcutaneous
- Parenteral routes 3 Prior to administration, caution is recommended to avoid precipitation of buprenorphine-induced opioid withdrawal 3.
Treatment Approach
A step-by-step approach to buprenorphine can be utilized to reach a sustained withdrawal relief, including:
- Evaluation of common opioid withdrawal symptoms
- Administration of buprenorphine
- Monitoring of symptoms and adjustment of treatment as needed 3 Patients may be safely discharged with safe-use counseling, close outpatient follow-up, and return precautions for continued management of their opioid use disorder 3.
