Background

  • Recommended as first-line treatment for opioid use disorder in Canadian guidelines
  • Typically coformulated with naloxone (trade name Suboxone) at a dose of 2 mg buprenorphine to 0.5 mg naloxone
  • Buprenorphine is partial μ-opioid receptor agonist
  • Strong receptor affinity, displaces other opioids and can precipitate withdrawal
  • Theoretical ceiling effect on side effects

Dosing

Standard Induction Protocol

  • It's use can precipitate withdrawal, so wait 12-24h after short-acting opioids, 18-36h after long-acting, or after tapering methadone, before starting buprenorphine
Day Buprenorphine Opioid
stop to ensure withdrawal (COWS ≥12)
1 2 to 4 mg + 2 mg q1h prn (max 12 mg) none
2 dose from yesterday + 2 mg q1h prn (max 16 mg) none

Microdosing Protocol

  • Suboxone combined with a short-acting opioid such as hydromorphone
  • In general, all opioids can be stopped once at a dose of buprenorphine 12 mg daily

Standard

Day Burprenorphine Short-acting opioid
1 0.5 mg maintain
2 1 mg maintain
3 1.5 mg maintain
4 2 mg maintain
5 2.5 mg maintain
6 3 mg maintain
7 4 mg + 2 mg q1h prn (max 12 mg) stop

Moderate

Day Burprenorphine Short-acting opioid
1 0.5 mg daily maintain
2 0.5 mg bid maintain
3 1 mg bid maintain
4 2 mg bid maintain
5 3 mg bid maintain
6 4 mg bid maintain
7 5 mg bid maintain
8 12 mg daily stop

Rapid

Day Burprenorphine Short-acting opioid
1 0.5 mg q4h x4 maintain
2 1 mg q4h x4 maintain
3 2 mg q4h x4 maintain
4 4 mg q4h x4 stop
5 16 mg daily + 2 mg prn stop

Ultra-rapid

Day Burprenorphine Hydromorphone
1 0.5 mg q3h (max 2.5 mg) 3 mg po q4h + 2-4 mg po q4h prn
2 1 mg q3h (max 8 mg) 3 mg po q4h + 2-4 mg po q4h prn
3 12 mg daily stop

Perioperative management

  • Consider tapering to 12 mg daily 2 to 3 days prior to surgery, or as low as 8 mg if a large or painful surgery
  • For the surgery itself, use NSAIDs, fentanyl, regional blocks, adjuncts, and non-pharmacologic options
  • Post-op, resume original dose as soon as possible, possibly split bid to tid to optimize for pain control, and continue non-buprenorphine pain management, including full agonist opioids if needed
