From the Guidelines
Buprenorphine is the most effective treatment for opioid withdrawal.
Management of Opioid Withdrawal
The management of opioid withdrawal typically involves the use of medications such as buprenorphine or methadone to alleviate symptoms, as well as symptomatic treatment with α2-adrenergic agonists, antiemetics, and other medications targeting withdrawal symptoms 1.
- Buprenorphine is considered a safe and effective treatment for opioid withdrawal, with studies suggesting it is superior to other modalities of treatment, including clonidine and lofexidine 1.
- Methadone is also an effective treatment for opioid withdrawal, with studies suggesting it is similar in effectiveness to buprenorphine 1.
- Initial dosing of buprenorphine may serve to initiate medication for addiction treatment (MAT) for opioid use disorder (OUD), with typical dosing starting at 2-4 mg, repeated at 2-hour intervals, if well tolerated, until resolution of withdrawal symptoms 1.
- Monitoring of patients undergoing opioid withdrawal treatment is crucial, with particular care required when transitioning from methadone to buprenorphine due to the risk of severe and prolonged precipitated withdrawal 1.
- Assessment tools, such as the Clinical Opiate Withdrawal Scale, may be used to assist in the assessment of severity of withdrawal 1. Key considerations in the management of opioid withdrawal include:
- Patient motivation: patients are often motivated to avoid withdrawal symptoms through continued hazardous opioid use 1.
- Symptomatic treatment: treatment of opioid withdrawal may be symptomatic, involving the use of α2-adrenergic agonists, antiemetics, and other medications targeting withdrawal symptoms 1.
- Precipitated withdrawal: buprenorphine may induce significant withdrawal symptoms if the patient is currently receiving opioids and not yet in withdrawal 1.
From the Research
Management of Opioid Withdrawal
The management of opioid withdrawal involves various pharmacological interventions. Some key points to consider are:
- 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 2, 3.
- Buprenorphine and methadone appear to be equally effective, but data are limited 2, 3.
- The use of buprenorphine to support transition to naltrexone treatment is an aspect worthy of further research 3.
- Current standards of care for medically supervised withdrawal include treatment with μ-opioid receptor agonists (eg, methadone), partial agonists (eg, buprenorphine), and α2-adrenergic receptor agonists (eg, clonidine and lofexidine) 4.
Comparison of Interventions
Some key comparisons between interventions are:
- Buprenorphine versus methadone: similar capacity to ameliorate opioid withdrawal, without clinically significant adverse effects 2, 3.
- Buprenorphine versus clonidine or lofexidine: buprenorphine is associated with a lower average withdrawal score, patients stay in treatment for longer, and are more likely to complete withdrawal treatment 2, 3.
- Different rates of buprenorphine dose reduction: it remains very uncertain what effect the rate of dose taper has on treatment outcome 3.
