How long does Sublocade last?

Sublocade lasts about one month per injection. The medication forms a depot under the skin and releases buprenorphine steadily for 26–30 days. Most people stay on a monthly schedule; some may extend slightly if stable, always under a clinician’s guidance.

People ask this first because planning work, childcare, and travel depends on it. Sublocade was designed to provide consistent buprenorphine exposure across a full month, unlike daily tablets or films. That steady level reduces the peaks and dips that can trigger cravings, and it simplifies daily routines.

At Road To Recovery, we coordinate monthly Sublocade appointments across our Ontario network to keep timing consistent. If you start in Barrie and need to continue in Brampton, our team helps secure the next appointment on time. That continuity is critical for comfort and confidence during recovery.

Summary at a Glance

Each Sublocade injection provides about one month of steady buprenorphine. Most schedules repeat every 26–30 days. Starting doses are typically two months at 300 mg, then 100 mg monthly maintenance when appropriate, always customized by a clinician.

• Monthly schedule: Plan 26–30 days between injections to maintain steady levels.
• Onboarding: Two initiation doses are common before monthly maintenance.
• Flexibility: Travel or shift work? We help coordinate appointments across our clinics.
• Support: Counseling, mental health referrals, and smoking cessation improve outcomes.

If you’re considering a switch from daily Suboxone, our clinicians assess stability, timing, and comfort level, then map the first three months so you know exactly what to expect.

Before you start: prerequisites for Sublocade

Before Sublocade, you should be stabilized on a transmucosal buprenorphine product (like Suboxone) and be free of precipitated withdrawal risk. You’ll complete intake, medical review, consent, and a plan for the first 90 days.

Beginning Sublocade safely involves several clinical checkpoints. We review medical history, current medications, and any prior reactions to buprenorphine. We also discuss goals: fewer clinic visits, more structure, or reducing the mental load of daily dosing.

• Stabilization step: Most people transition from daily buprenorphine. This confirms tolerance and comfort.
• Medical screening: Allergies, injection site considerations, and any liver concerns are reviewed.
• Consent and expectations: We cover duration (about one month per dose), side effects, and the next three appointments.
• Supportive care: We can arrange psychiatry referrals and counseling through our partners if helpful.

Step-by-step: what to expect each month on Sublocade

Expect a brief monthly appointment, an abdominal subcutaneous injection, and a check-in on cravings, sleep, and mood. Plan the next date 26–30 days later. Most find steady comfort after the first two injections.

Step 1 — Map your dates

We help you pick a repeating day-of-month that fits your routine. Many choose the first Monday or a pay-cycle anchor to remember it easily. Traveling? We can coordinate a nearby clinic visit so you don’t miss a beat.

• Tip: Aim for 28 days between doses; book the next visit before you leave.
• Backup: If you’re delayed, call us promptly. We’ll review symptoms and adjust.

Step 2 — Injection day

On the day, you’ll confirm any changes in medications or health, then receive a quick abdominal injection. The medication forms a small depot under the skin and dissolves over the month. You can resume normal activities after a short observation period.

• Common sensations: Mild pressure or tenderness at the site is typical for 24–48 hours.
• Avoid manipulation: Don’t massage or press the area; let the depot settle.

Step 3 — The first 72 hours

Mood, sleep, and cravings usually remain stable. If you’re transitioning from daily buprenorphine, your brain adapts to flatter, steadier exposure. Many describe less “medication on the mind” after the first week.

• Hydration and rest: These simple habits smooth the experience.
• Support check-ins: Brief counseling or peer support helps reinforce progress.

Step 4 — Weeks 2–4

The depot steadily releases buprenorphine, so most people feel consistent from day 7 to day 28. If you notice breakthrough cravings late in the cycle, tell us. We can adjust the maintenance dose after two initiation doses.

• Red flags: Persistent cravings, sleep disruption, or mood swings warrant a quick call.
• Planning: Keep the next appointment locked at 26–30 days.

Here’s a visual detail from the clinical process.

Troubleshooting: missed or late injections

If you’re a few days late, contact your clinic. Most patients can receive the next dose promptly with a clinical check. If it’s been longer, we’ll reassess symptoms and determine the safest way to restart.

Life happens. Flights get delayed, work shifts extend, and child care falls through. The key is staying in contact. Our team triages by symptoms first: Are you feeling cravings? Any early withdrawal signals? We then review timing and options.

• Late by less than a week: We’ll usually dose at the next earliest appointment and reset your schedule.
• Late by more than a week: We’ll assess and may adapt the plan to keep you comfortable.
• Injection site concerns: Redness or swelling beyond two to three days? Call us for guidance.

Advanced tips for staying stable between doses

Stability improves when routines are predictable: consistent sleep, nutrition, stress management, and appointment timing. Use calendar holds, mobile reminders, and quick symptom check-ins with your care team.

In our experience, small habits protect the monthly rhythm. Patients who set the next appointment before leaving the clinic rarely drift outside the 26–30 day window. Similarly, a five-minute weekly self-check (cravings, sleep, stress) flags issues early so we can help.

• Calendar anchors: Pin the same weekday each month and share the event with a support person if helpful.
• Wellness stack: Short, regular walks and balanced meals stabilize energy across the month.
• Integrated care: If anxiety or depression spikes, ask about our mental health referrals.

Local considerations for all over ontario

• Winter weather can disrupt travel; book earlier day-of appointments and consider virtual check-ins for counseling when roads are challenging.
• Holiday periods fill fast; set your next two Sublocade dates before late-year rushes to keep doses 26–30 days apart.
• Working shifts? Our multi-location network helps you keep timing consistent if your schedule moves between sites.

Sublocade vs. other OAT options

Sublocade offers monthly, steady buprenorphine without daily dosing. Suboxone requires daily adherence but allows flexible titration. Methadone is daily and highly structured, often ideal for severe dependence. Your history and goals decide the fit.

Choosing a path is about fit, not hierarchy. Some prefer daily contact with a pharmacy; others want one-and-done monthly accountability. Our clinicians look at your history of withdrawal, cravings, work schedule, and preferences to guide the match.

Therapy	Dosing rhythm	Typical visit cadence	Best for
Sublocade (XR buprenorphine)	Monthly injection	Every 26–30 days	People who want steady levels and fewer daily decisions
Suboxone (buprenorphine/naloxone)	Daily film/tablet	Weekly → monthly once stable	People who want flexible adjustment or at-home dosing
Methadone	Daily liquid	Daily pickup early; take-homes with stability	People with high tolerance or who benefit from high structure
