II. Management: General
- See Opioid Withdrawal
- See Opioid Use Disorder in Pregnancy
- Precautions
- Treat Opioid Addiction as a chronic disease
- Relapse is common, but roughly 35% of patients do not relapse in 1 year on medical therapy (e.g. Buprenorphine)
- Avoid stigmatizing patients for their Opioid use
- Employ an open door policy for patients to return for Chemical Dependency treatment when they are ready
- With continued Opioid use, help patients practice harm reduction (see below)
- Overall Recommended approach
- Prescribe intranasal Naloxone for home
- Initiate Opioid Agonist Therapy (OAT)
- Buprenorphine or Buprenorphine/Naloxone (Suboxone) Initiation
- Buprenorphine is approved in U.S. for OUD in age >=16 years
- Patient must be in at least mild Opioid Withdrawal (COWS>=8) when starting Buprenorphine
- Opioid Agonists are the most effective measure for the treatment of moderate to severe OUD
- Refer to Outpatient-Based Opioid Treatment (OBOT)
- Social support or peer recovery coaches
- Counseling
- Precautions
- Behavior therapy should be offered to all OUD patients
- Counseling should not be a stipulation for a opioid Agonist prescription
- OUD patients have the same outcomes with and without counseling

- Chemical Dependency Rehabilitation
- Narcotics Anonymous
- Outpatient-Based Opioid Treatment (OBOT)
- Place referral at time of evaluation, initiation of medication management
- Precautions
III. Management: Medications for Opioid Use Disorder (MOUD, OUD-MAT)
- Medical Management: Single Agent Agonists (no X-waiver required)
- Buprenorphine (Buprenex)
- See Buprenorphine for initiation protocols
- Highly effective in withdrawal and craving relief
- Buprenorphine >=16 mg appears most effective at preventing relapse
- Low precipitated withdrawal rate when given 16 mg in Emergency Department
- Approved for use in age 16 and older, and considered safe in pregnancy
- Partial opioid Agonist with effect ceiling and blocks other Opioids (e.g. Heroin)
- However, may be abused if crushed and injected
- Available as sublingual (Subutex), implants (Probuphine) and long-acting intramuscular (Sublocade)
- Buprenorphine/Naloxone (Suboxone, Zubsolv SL)
- Naloxone is inactive unless injected, hence countering Buprenorphine injection misuse
- Preferred Buprenorphine formulation for most patients
- Avoid in pregnancy (use Buprenorphine instead)
- Has been misused by snorting
- Buprenorphine/Naloxone may be referred to as dual therapy (in contrast to monotherapy with Buprenorphine alone)
- Buprenorphine (Buprenex)
- Medical Management: Other Single Agents Agonists (require special X-DEA Number to prescribe)
- Methadone
- High risk for Opioid Overdose (typically administered by Methadone clinic)
- Approved for use in age 18 and older, and considered safe in pregnancy
- Levomethadyl (Orlaam)
- Methadone-like agent
- Methadone
- Medical Management: Single Agent Antagonists
- Naltrexone (Trexan, Vivitrol)
- Reduces risk of non-prescribed Opioid use (more so with SR formulation)
- Unlike Agonists (e.g. Buprenorphine), Naltrexone does not reduce risk of death or serious adverse effects
- Buprenorphine (or other Agonists) are preferred over Naltrexone for longterm MOUD
- References
- Naltrexone (Trexan, Vivitrol)
- Treatment strategy
- MOUD is used as long-term therapy for uncontrolled, refractory Opioid Abuse as a chronic illness
- Correct the misconception that patients are trading one addiction for another
- Reframe these agents for addiction, as similar to Insulin in Diabetes Mellitus
- May be continued for as long as the patient finds benefit
- Continued use >15-18 months is associated with the lowest relapse rates
- Williams (2020) Am J Psychiatry 177(2):117-24 +PMID: 31786933 [PubMed]
- Abstinence alone, even after CD treatment, is not typically effective
- Relapse rates after treatment approach 90% within one month
- Addiction medications (e.g. Buprenorphine, Methadone) are intended for longterm use to prevent relapse
- Goal is prevention of continued uncontrolled Opioid Abuse (e.g. Heroin Overdose)
- Mortality from uncontrolled Opioid Addiction is very high
- MOUD is used as long-term therapy for uncontrolled, refractory Opioid Abuse as a chronic illness
- Drug Testing
- Perform at every visit initially and then periodically at random visits
- Testing does not need to be observed
- Urine specimen validity may be confirmed with Temperature, pH, specific gravity, Creatinine
- Buprenorphine and norbuprenorphine urine levels should be roughly equivalent
- Adulterated samples will be high in Buprenorphine and low or absent in norbuprenorphine
- Drug testing benefits when prescribing medications in OUD
- Confirms compliance with prescribed medications (e.g. Buprenorphine)
- Evaluates for other substances that may put patients at risk (increased mortality)

IV. Management: MOUD Tapering or Discontinuation
- Precautions
- Medications for Opioid Use Disorder (MOUD) are intended for longterm use
- Relapse rates after discontinuing MOUD are very high (50% in first month)
- Overdose risk is highest in the first 4-6 weeks after stopping MOUD (RR 4-6)
- More than 50% of patients discontinue MOUD within first 6 months
- Insurance lapse
- Stigma
- Dependence on MOUD perceived as one dependence replaced by another
- Financial and logistical difficulties
- Non-compliance
- Punative MOUD discontinuation is not recommended (e.g. missed appointments, missed drug screens)
- Work with patients to maintain MOUD despite lapses in compliance
- Tapering strategy
- Review the goals of tapering
- Review the high risk of relapse and emergency planning
- Review options for managing Opioid Withdrawal symptoms and cravings
- See Opioid Withdrawal
- Consider returning to last tolerated dose reduction if intolerable withdrawal symptoms
- Opioid Withdrawal symptoms are greatest with daily Opioid dose <2 mg/day
- Consider final bridging off Buprenorphine with extended release Buprenorphine SQ
- Brixadi is available at 8, 16, 24 and 32 mg weekly
- Brixadi is available at 64, 96 and 128 mg monthly
- Sublocade is available at 100 and 300 mg doses monthly
- Example: 300 mg SQ monthly for 2 months, then 100 mg SQ monthly for >=1 month
- When transitioning daily Buprenorphine doses <=8 mg/day, use 100 mg SQ monthly
- Consider final bridging off Buprenorphine with transdermal patch as needed
- Butrans patch is available at 5, 7.5, 10, 15, 20 mcg/hour weekly
- Consider final bridging off Buprenorphine with extended release Buprenorphine SQ
- Reduce the risk of nonprescribed Opioid use and Overdose risk
- Provide Naloxone prescription
- Encourage psychosocial support
- Encourage Mindfulness activities and Exercise
- Consider mutual help groups
- Arrange close interval follow-up after discontinuation
- At 24-48 hours after stopping daily SL Buprenorphine (e.g. Suboxone)
- At 1-2 weeks after last weekly Buprenorphine patch (Butrans)
- At 2-4 weeks after last monthly SQ Buprenorphine injection (Sublocade, Brixadi)
- Arrange regular follow-up communication (staff phone calls, in-person visits, TeleHealth visits)
- Highest risk of relapse is in the first 4-6 weeks of MOUD discontinuation
- Encourage longer maintenance periods before tapering (>12 months)
- Shorter maintenance periods (<3-6 months) are associated with higher relapse and Overdose rates
- Longer maintenance period (>12 months) prior to tapering or discontinuation is preferred
- Mortality benefits are sustained for up to 4-5 years on MOUD maintenance therapy
- Encourage slower MOUD Tapers
- Example: Decrease Buprenorphine dose 2 mg every 1-2 months over a 12 month period
- Slow Buprenorphine tapers (<=2 mg/month) have less Overdose risk than faster tapers (>=4 mg/month)
- Less frequent dose reductions (every 1-2 months) are preferred for less Overdose risk
- Longer total taper periods (12 months) are associated with lower relapse and Overdose risk than 6 month tapers
- Example Taper schedule
- Initial taper: 2 mg decrease every 1-2 months (e.g. 14 mg/day, 12 mg/day, 10 mg/day, 8 mg/day)
- Next taper: 1 mg decrease every 1-2 months (e.g. 7 mg/day, 6 mg/day, 5 mg/day, 4 mg/day, 2 mg/day)
- Final taper: 1 mg/day for 1-2 months, then off and weekly Butrans patch as needed (when dose <2 mg/day)

Opioids
- Monitor patient carefully for hypoventilation and apnea
- Continuous Pulse Oximetry
- Capnography (if available)
- Maintain Buprenorphine dosing during the emergency department visit, hospitalization and perioperative period
- Buprenorphine has an MME 40 (1 mg Buprenorphine = 40 mg Morphine)
- Patients are often taking 8 mg or more of Buprenorphine (equivalent to 320 mg Morphine)
- Replacing Buprenorphine with other Opioids will require exceedingly high doses
- Alert Buprenorphine/Naloxone prescriber of acute Pain Evaluation and acute Opioid prescription
- May otherwise void Controlled Substance Contract with the prescriber
- Divide Buprenorphine/Naloxone dosing every 6 to 8 hours (maximum daily dosing up to 32 mg)
- Buprenorphine/Naloxone tightly binds Opioid receptors, preventing withdrawal for full day
- However, Analgesic effect wanes more quickly, and therefore divided dosing may be needed
- Although tabs/films may be cut in half, may result in uneven dosing (consider new prescription)
- Consider adding other adjunctive agents in acute pain
- See above
- May add short acting Opioids, but risk of relapse
- Monitor patient carefully for hypoventilation and apnea
