Assessment
Opioid Use Disorder (OUD), in sustained remission (DSM-5 criteria met at baseline; currently abstinent from illicit opioids × 6 months). 1, 4
Major Depressive Disorder, stable on sertraline 50 mg daily. 1
No concurrent substance use disorders (alcohol, benzodiazepines, stimulants). 1
Infectious disease screening up to date (hepatitis C and HIV). 1
Plan
1. Continue Buprenorphine/Naloxone Maintenance Therapy
Current Dose:
- Buprenorphine/naloxone 8 mg/2 mg sublingual daily. 1
- Patient is stable at this dose; however, the target maintenance dose for most patients is 16 mg daily. 1 Consider dose optimization if any breakthrough cravings emerge, though none are currently reported. 1
Duration of Treatment:
- There is no maximum recommended duration of maintenance treatment—patients may require treatment indefinitely. 5 Maintenance therapy is substantially more effective than tapering for preventing relapse. 5 Abrupt discontinuation markedly increases the risk of opioid overdose and death due to reduced opioid tolerance. 1
Rationale for Buprenorphine/Naloxone (Suboxone) Over Buprenorphine Alone:
- The buprenorphine/naloxone combination is preferred for most patients because the naloxone component reduces misuse potential by preventing injection diversion. 4 The naloxone is poorly absorbed sublingually and does not contribute to withdrawal prevention. 5
2. Behavioral Therapy and Psychosocial Support
- Continue weekly individual counseling as part of comprehensive medication-assisted treatment. 1, 2 All FDA trials of buprenorphine used psychosocial counseling in conjunction with medication; there is no evidence supporting buprenorphine as monotherapy. 2
- Assess employment, education, and support system at each visit. 1
- Encourage family involvement in treatment planning. 1
3. Monitoring and Follow-Up
Visit Frequency:
- Monthly follow-up visits for stable patients. 1 (Increase frequency if any relapse, reemergence of cravings, or withdrawal symptoms occur.) 3
At Each Visit, Document:
- Vital signs (blood pressure, heart rate, respiratory rate, temperature, oxygen saturation). 1
- Physical examination findings: Inspect for track marks, abscesses, or signs of injection drug use. 1
- Cravings or withdrawal symptoms (use Clinical Opiate Withdrawal Scale [COWS] if indicated). 1
- Any relapses or illicit opioid use. 3
- Pill/wrapper counts to assess adherence. 3
- State prescription drug monitoring program (PDMP) checks. 3
Urine Drug Testing (UDS):
- Random UDS at each visit to assess for continued illicit opioid use and concurrent substance use (benzodiazepines, cocaine, methamphetamine). 1 Sporadic opioid use in the first few months is not uncommon and should be addressed with increased visit frequency and more intensive behavioral therapy engagement. 3
Laboratory Monitoring:
- Routine LFTs every 3–6 months are NOT required for buprenorphine/naloxone maintenance (unlike naltrexone). 1
- Hepatitis C and HIV screening if not previously completed. 1
4. Mental Health Management
Depression:
- Continue sertraline 50 mg daily. 1
- Screen for depression at each visit using PHQ-2; if positive (≥3), administer PHQ-9. 4
- Refer for psychiatric evaluation if PHQ-9 ≥10. 4
Other Psychiatric Comorbidities:
- Systematically screen for anxiety, PTSD, bipolar disorder, and other psychiatric conditions at baseline and periodically. 1
- Assess sleep quality and screen for insomnia. 1
Buprenorphine's Potential Mood-Stabilizing Effects:
- Emerging evidence suggests buprenorphine may have rapid antidepressant and antisuicidal effects via κ-opioid receptor antagonism. 6, 7 This may contribute to the patient's stable mood on current therapy.
5. Safety Considerations
Avoid Concurrent Benzodiazepines:
- Concomitant use of buprenorphine with benzodiazepines is contraindicated due to FDA black-box warning for increased risk of respiratory depression and death. 1, 5 If benzodiazepines are prescribed, initiate a gradual taper and substitute non-benzodiazepine anxiolytics (SSRIs, SNRIs, buspirone, gabapentin). 5
QT-Prolonging Medications:
Overdose Prevention:
- Provide take-home naloxone kit and overdose prevention education at discharge and periodically. 5
6. Acute Pain Management (If Needed in Future)
- Continue the usual buprenorphine/naloxone dose and add short-acting opioid analgesics for breakthrough pain. 1 Higher opioid doses may be necessary due to buprenorphine's high receptor affinity. 1
- Alternatively, increase the buprenorphine dose for additional analgesia, as higher doses provide pain relief without the respiratory depression ceiling effect seen with full agonists. 4
7. Common Pitfalls to Avoid
- Never discontinue buprenorphine abruptly to comply with opioid dose guidelines; buprenorphine for OUD has a ceiling effect on respiratory depression and should not be tapered or discontinued. 5
- Do not initiate buprenorphine while the patient is under the influence of full opioid agonists (to avoid precipitated withdrawal). 1
- Do not discharge the patient on α₂-agonists (clonidine/lofexidine) without a definitive addiction-treatment plan; these agents only address acute withdrawal and are inferior to buprenorphine. 5
8. Patient Education
- Reinforce the importance of adherence to buprenorphine/naloxone and weekly counseling. 1, 2
- Educate on the risks of relapse if treatment is discontinued. 1, 5
- Discuss naloxone use for overdose prevention. 5
- Encourage continued engagement with support systems and counseling. 1
9. Disposition
- Return to clinic in 1 month for routine follow-up. 1
- Contact clinic immediately if cravings, withdrawal symptoms, or relapse occur. 3
- Emergency contact information provided for after-hours crises.
