Suboxone Sublingual Film Dosages
For opioid use disorder treatment, initiate Suboxone with 4-8 mg sublingual on Day 1 (given only when moderate withdrawal symptoms appear), increase to 16 mg on Day 2, then maintain at 16 mg daily as the target dose, with a typical maintenance range of 4-24 mg daily. 1
Induction Phase Dosing
Timing Requirements Before First Dose
- Short-acting opioids (heroin, morphine IR): Wait at least 4 hours, but preferably >12 hours after last use 1, 2
- Extended-release formulations (OxyContin): Wait >24 hours after last use 2
- Methadone maintenance: Wait >72 hours after last use (consider continuing methadone instead) 2, 1
Initial Dosing Strategy
- Day 1: Administer 8 mg sublingual when objective signs of moderate opioid withdrawal appear 1
- Day 2: Increase to 16 mg sublingual 1
- Day 3 onward: Continue 16 mg daily as target maintenance dose 1
Withdrawal Severity-Based Dosing (Emergency Department Protocol)
- Mild withdrawal (COWS <8): No buprenorphine indicated; reassess in 1-2 hours 2
- Moderate to severe withdrawal (COWS ≥8): Give 4-8 mg sublingual based on severity; reassess after 30-60 minutes 2
Maintenance Phase Dosing
Target Maintenance Dose
- Recommended target: 16 mg sublingual once daily 1
- Typical range: 4-24 mg buprenorphine per day 1
- Maximum studied dose: 24 mg daily (higher doses show no additional clinical advantage) 1
Dose Adjustments
- Adjust in increments/decrements of 2 mg or 4 mg to maintain treatment retention and suppress withdrawal symptoms 1
- Titrate to clinical effectiveness as rapidly as possible to reduce early dropout rates 1
Administration Technique
Critical Instructions
- Place tablets/films under the tongue until completely dissolved 1
- Do not cut, chew, or swallow the medication 1
- Avoid eating or drinking until fully dissolved 1
- For doses requiring >2 tablets: place all at once if possible, or place 2 at a time sequentially under tongue 1
Bioavailability Considerations
- Sublingual absorption is rapid with peak plasma concentration at 1 hour 3
- Buprenorphine has very low oral bioavailability due to extensive first-pass metabolism 4
- Consistent administration technique is essential for stable bioavailability 1
Prescribing for Unsupervised Administration
Emergency Department Discharge Protocol
- X-waivered prescribers: Prescribe 16 mg sublingual daily for 3-7 days until follow-up 2
- Non-X-waivered prescribers: Patients may return for up to 3 consecutive days for interim treatment 2
- Sample 3-day prescription: Buprenorphine/naloxone 8 mg/2 mg sublingual film, take 2 films once daily in AM, dispense #6, no refills 2
Supervision Recommendations
- Begin with supervised administration, progressing to unsupervised as clinical stability permits 1
- See patients at reasonable intervals (ideally at least weekly during first month) 1
- Avoid multiple refills early in treatment or without appropriate follow-up visits 1
Pharmacokinetic Considerations
Dose-Response Relationship
- Plasma buprenorphine concentrations increase with dose but not proportionally—the 32 mg dose produces only 54% of the dose-adjusted exposure compared to 4 mg 5
- Most subjective and physiological effects plateau at higher doses due to partial agonist properties 5
- Large inter-subject variability exists in plasma levels and clinical response 3
Naloxone Component
- The 4:1 buprenorphine:naloxone ratio is designed to deter injection abuse 6
- Naloxone is poorly absorbed sublingually and does not affect buprenorphine's efficacy when taken as prescribed 3, 7
- Intramuscular injection precipitates withdrawal in opioid-dependent persons, reducing abuse potential 7
Duration of Treatment
- No maximum duration for maintenance treatment 1
- Patients may require treatment indefinitely and should continue as long as they are benefiting 1
- Treatment effectiveness is comparable to methadone for opioid dependence 6
Critical Pitfalls to Avoid
- Never administer before withdrawal symptoms appear—buprenorphine's high receptor affinity can precipitate severe withdrawal in patients with recent full agonist opioid use 1, 2
- Methadone patients are at highest risk for precipitated withdrawal, especially those on >30 mg daily 1
- Do not confuse formulations: Sublingual films/tablets are for opioid use disorder; transdermal patches are only for chronic pain management 8
