Transition from Suboxone to Sublocade
Sublocade can be started after a minimum of 7 days of transmucosal buprenorphine (Suboxone) stabilization, though emerging evidence supports safe transitions within 24-48 hours in select patients.
Standard FDA-Approved Approach
The traditional recommendation requires at least 7 days of stabilization on sublingual buprenorphine/naloxone (Suboxone) before initiating Sublocade (extended-release buprenorphine injection) 1. This approach ensures:
- Adequate tolerance to buprenorphine is established
- Therapeutic plasma levels are maintained (approximately 2 ng/mL or above) 2
- Risk of precipitated withdrawal is minimized
Accelerated Transition Protocols (Emerging Evidence)
Recent research demonstrates that transitions within 24-48 hours are feasible and well-tolerated in clinical practice 3, 4:
- A 2025 scoping review of 534 patients found that 75 patients successfully transitioned to Sublocade within 24 hours, with only 4% experiencing withdrawal symptoms requiring additional opioid support 3
- Short-term retention at 4 weeks exceeded 60% with accelerated protocols 3
- A case report documented successful transition after only 48 hours of transdermal buprenorphine induction without precipitating withdrawal 4
Direct-to-Inject Approach (Most Aggressive)
Direct-to-inject protocols without prior sublingual stabilization are being explored in outpatient settings 5:
- A 2025 case series of 21 patients showed 77% received no buprenorphine in the preceding 24 hours before Sublocade injection 5
- Patient experiences varied: 27% felt fine, 59% felt unwell but manageable, and 14% felt very rough 5
- Retention rates were excellent: 77% at 7 days and 73% at 30 days post-injection 5
Clinical Decision Algorithm
For standard patients with moderate-to-severe opioid use disorder:
- Stabilize on sublingual buprenorphine/naloxone for 7 days minimum 1
- Ensure patient tolerates the medication without significant adverse effects
- Initiate Sublocade 300 mg subcutaneous injection 2
For high-risk patients (risk of disengagement, potent illicit opioid use):
- Consider accelerated transition within 24-48 hours after confirming tolerance to initial sublingual doses 3, 4
- Monitor closely for withdrawal symptoms in the first 24 hours post-injection
- Have additional buprenorphine support available if needed (only 4% require this) 3
For patients in acute settings (hospitalized, incarcerated):
- Direct-to-inject may be considered to prevent treatment dropout 5
- Counsel patients that 73% experience some discomfort but most find it tolerable 5
- Ensure follow-up within 7 days is secured 5
Important Caveats
The 7-day stabilization period remains the FDA-approved standard and should be followed unless specific clinical circumstances warrant acceleration 1. The accelerated approaches are supported by emerging evidence but are not yet formally endorsed in product labeling.
Avoid these common pitfalls:
- Do not assume all patients need the full 7-day stabilization—this can delay care and increase disengagement risk in high-risk populations 3
- Do not use accelerated protocols without adequate monitoring and support systems in place 4
- Do not fail to counsel patients about potential post-injection discomfort with rapid transitions 5
