Sublocade: What It Is and How It Fits Opioid Recovery
Sublocade is an extended-release buprenorphine injection given once a month by a healthcare professional. It delivers the same medicine as Suboxone, but instead of dissolving a film every morning you receive a single injection under the skin of the abdomen that releases buprenorphine steadily for about 30 days. It is approved for moderate to severe opioid use disorder in adults who have already started on a buprenorphine tablet or film. For people who struggle with daily dosing, live in unstable housing, travel for work, or simply want the decision taken off the table each morning, the monthly shot removes a daily point of failure.
Quick answers
What is Sublocade?
It is buprenorphine in an extended-release liquid that turns into a small gel deposit under the skin. The deposit releases medicine slowly, keeping steady blood levels for about a month.
Who is it for?
Adults with moderate to severe opioid use disorder who have been stable on a transmucosal buprenorphine product, such as Suboxone, for at least seven days.
Does it hurt?
Most people describe a brief sting and pressure in the abdomen, then soreness, itching or a small lump at the site for a few days. The lump shrinks as the medicine is absorbed.
Can I stop it whenever I want?
You can stop having injections, but buprenorphine stays in your system for months after the last dose. That means a slow natural taper rather than a sudden stop, which many people find easier.
How the monthly injection works
Sublocade is buprenorphine dissolved in a carrier that solidifies on contact with body fluid. A clinician injects it just under the skin of the abdomen. Within minutes it forms a soft gel deposit that slowly breaks down, releasing buprenorphine into the bloodstream at a near-constant rate.
- Buprenorphine is a partial opioid agonist that relieves withdrawal and cravings without the high of full agonists like heroin or fentanyl.
- Steady blood levels avoid the peaks and troughs some people feel between daily doses.
- It occupies opioid receptors strongly, so other opioids produce little or no effect while it is in place.
- No take-home medicine means nothing to lose, forget, divert or have stolen.
How treatment starts, step by step
- Start on a buprenorphine tablet or film and take it for at least seven days, so your prescriber can confirm you tolerate the medicine.
- Attend a clinic visit for the first injection, usually 300 mg, given in the abdomen.
- Return about a month later for a second 300 mg dose.
- Move to a 100 mg monthly maintenance dose, or stay at 300 mg if cravings persist or you have high tolerance.
- Keep monthly appointments, with counseling or peer support alongside the medicine.
Sublocade compared with daily Suboxone
| Sublocade | Suboxone | |
|---|---|---|
| Dosing | One injection every month at a clinic | Film or tablet under the tongue, every day |
| Who administers | Healthcare professional only | You, at home |
| Missed dose risk | Low, one appointment a month | Higher, a missed morning can start cravings |
| Flexibility | Dose fixed for the month | Dose can be adjusted quickly |
| Diversion risk | None, nothing leaves the clinic | Possible, medicine is held at home |
| Cost | High list price, usually billed as a medical benefit | Cheap generics widely available |

Side effects and safety
| Common | Less common but important |
|---|---|
| Injection site pain, itching or a lump | Liver enzyme changes, checked with blood tests |
| Constipation | Precipitated withdrawal if buprenorphine is started too early |
| Headache and nausea | Serious harm if injected into a vein, which is why only clinicians give it |
| Tiredness in the first weeks | Dangerous sedation if combined with benzodiazepines or alcohol |
- Tell every clinician you see that you are on extended-release buprenorphine, especially before surgery or if you need pain relief.
- Keep naloxone at home even while on treatment, and make sure someone you live with knows where it is.
- Do not try to remove or squeeze the deposit under your skin.
Cost, coverage and access
- Sublocade is dispensed through a restricted program and given in a certified healthcare setting, so it is usually billed as a medical benefit rather than a pharmacy prescription.
- Medicaid covers it in every state, though prior authorization is common.
- Medicare Part B may cover it when given in an office setting; Part D covers some cases.
- Commercial plans generally cover it after prior authorization, often requiring a trial of oral buprenorphine first.
- The manufacturer runs a patient support program, and opioid treatment programs and federally qualified health centers often provide it on a sliding scale.

How long people stay on it
There is no fixed end point. Longer treatment is linked to better outcomes, and many people stay on buprenorphine for years, the same way someone stays on medication for another long-term condition. Decide about stopping when life is stable, not during a crisis.
- Buprenorphine levels fall slowly for months after a final injection, which acts as a built-in taper.
- Overdose risk rises once tolerance drops, so plan ahead and keep naloxone on hand.
- If cravings return, resuming treatment is a sensible step, not a failure.
Frequently asked questions
Is Sublocade the same medicine as Suboxone?
The active medicine is the same, buprenorphine. Suboxone also contains naloxone to deter misuse by injection, which Sublocade does not need because a clinician administers it.
What happens if I miss my monthly appointment?
Doses can be given a few days early or up to two weeks late without losing protection, but contact your clinic as soon as you know. Do not use other opioids to cover a gap.
Can I feel the deposit under my skin?
Yes, most people feel a small firm lump for a few weeks. It softens and shrinks as the medicine is absorbed and it is not harmful.
Will Sublocade block pain medication after surgery?
It can reduce the effect of other opioids. Tell your surgical team well in advance so they can plan pain control, which is usually still possible.
Can I take Sublocade while pregnant?
Buprenorphine is used in pregnancy and is safer than continued illicit opioid use, but the extended-release form has less pregnancy data. This needs a specialist discussion.
Is this just swapping one addiction for another?
No. Addiction means compulsive use despite harm. A prescribed dose that removes cravings and restores normal function is treatment, and the evidence on survival is strong.
