Understanding long acting injectable Sublocade treatment
If you are exploring medication options for opioid use disorder, long acting injectable Sublocade treatment is one option your provider may recommend. Sublocade is a once monthly injection that delivers a steady dose of buprenorphine, which can help you manage cravings and withdrawal symptoms without needing a daily pill or film. It is one of several FDA approved medications for opioid use disorder, along with methadone, Suboxone and Subutex.
Knowing how Sublocade works, who it is best for and how it compares with other medications can help you have a more informed conversation with your treatment team.
What Sublocade is and how it works
Sublocade is a long acting injectable form of buprenorphine used to treat moderate to severe opioid use disorder. It is an extended release medication that is injected under the skin by a healthcare professional, usually once every month in a clinic setting, not at home. [1]
Buprenorphine’s role in opioid treatment
Buprenorphine is a partial opioid agonist. That means it attaches to the same mu opioid receptors in your brain as drugs like heroin, fentanyl and prescription painkillers, but it activates them less strongly. This helps to:
- Reduce cravings
- Prevent or ease withdrawal symptoms
- Block or blunt the effects of other opioids
Sublocade also blocks kappa receptors in the brain, which may contribute to improved mood and reduced dysphoria during treatment. [2]
How the long acting injection works
After your provider injects Sublocade under the skin, the medication reacts with body fluids and forms a small solid mass at the injection site. This depot then slowly breaks down over about a month and steadily releases buprenorphine into your bloodstream. [2]
This extended release system:
- Maintains more consistent buprenorphine levels
- Minimizes the daily highs and lows that can occur with shorter acting medications
- Provides continuous protection against withdrawal and cravings between appointments
Sublocade begins working shortly after the first injection and can start controlling cravings and withdrawal symptoms quickly when used as directed. [2]
Who long acting injectable Sublocade treatment is for
Sublocade is approved for adults with moderate to severe opioid use disorder. It is not usually a first dose medication. Instead, you typically begin treatment with a sublingual (under the tongue) buprenorphine product such as Suboxone or Subutex, then transition to Sublocade once you are stable.
According to clinical guidance, buprenorphine extended release injection is indicated for people who have already been inducted and clinically stabilized on a transmucosal buprenorphine product, and it should always be used along with counseling and psychosocial support. [3]
Same day start option
Recent updates allow some patients to start Sublocade more quickly. Sublocade now offers a same day start option, even for people who have not been on buprenorphine before, as long as you:
- First receive and tolerate a test dose of a transmucosal buprenorphine product
- Are monitored for withdrawal or sedation
If you tolerate the test dose, your provider may be able to give your first Sublocade injection that same day. [4]
Who may benefit most
Long acting injectable Sublocade treatment may be a good fit if you:
- Have difficulty remembering or managing daily medication
- Worry about losing, sharing or diverting your medication
- Prefer fewer pharmacy visits and more privacy
- Want more stable symptom control over the month
- Have done well on buprenorphine but want a simpler routine
Because the medication is administered only in healthcare settings under the Sublocade REMS Program, it can reduce the risk of misuse and improve safety. [1]
How Sublocade compares to methadone, Suboxone, and Subutex
Sublocade is one of several evidence based options within modern medication options for opioid use disorder. Each medication has its own strengths, dosing pattern and safety profile.
Big picture comparison
| Medication | How it is taken | Typical setting | Best for |
|---|---|---|---|
| Methadone | Daily oral liquid or tablet | Specialized methadone clinic with frequent visits | People who need a full opioid agonist and structured daily support |
| Suboxone (buprenorphine/naloxone) | Daily film or tablet under the tongue | Office based outpatient, pharmacy pick up | People who can manage daily dosing and want flexibility |
| Subutex (buprenorphine only) | Daily sublingual tablet | Office based outpatient | People who cannot take naloxone, such as some pregnant patients |
| Sublocade | Monthly injection under the skin in clinic | Office based or clinic, no take home doses | People stabilized on buprenorphine who want long acting relief and less daily responsibility |
You can explore each option in more detail through your local methadone clinic treatment program, suboxone treatment program outpatient, or subutex treatment for opioid addiction, as well as a dedicated sublocade treatment program.
Dosing and structure
-
Methadone is usually taken once per day at a clinic. Many programs require supervised dosing, especially early on. Over time, you may earn take home doses through a methadone maintenance treatment or methadone assisted recovery program.
-
Suboxone and Subutex are generally taken once or twice daily at home, with periodic office visits and prescription refills. These often form the backbone of a suboxone based recovery program, subutex outpatient treatment or other outpatient opioid medication treatment.
-
Sublocade is given once a month during a scheduled appointment. There are no daily take home doses, which simplifies your routine but requires a commitment to monthly in person visits. Some people continue to receive Sublocade as part of a longer term sublocade maintenance program.
Safety and monitoring
All of these medications should be used under close opioid addiction medication management with a qualified provider. However, there are some differences in risk and oversight:
-
Methadone is a full opioid agonist and can cause respiratory depression if misused or combined with other sedating substances. Clinic based dosing is one reason methadone treatment program outpatient services are tightly regulated.
-
Suboxone and Subutex carry a lower overdose risk than methadone, but can still be misused or combined with other substances. Careful medication management for opioid addiction and a structured suboxone and therapy program or opioid dependence medication program help reduce these risks.
-
Sublocade is non divertible, since the medication is locked under your skin rather than in a bottle at home. Clinical trials reported no respiratory depression or overdoses in active Sublocade groups. [3] You still need regular medical follow up and liver function monitoring.
There is no single best medication for everyone. Your history, current use, medical conditions and goals all shape the right choice within a physician managed opioid medication program.
Evidence for effectiveness of Sublocade
Sublocade has been studied in large clinical trials and real world programs, and the results support its use as an effective option for many people.
In one pivotal 24 week randomized controlled trial of adults with moderate to severe opioid use disorder, monthly Sublocade doses achieved a mean abstinence rate of about 42 to 43 percent, compared with 5 percent for placebo. This was a statistically significant difference from weeks 5 to 24. [3]
An open label extension over 48 weeks found mean abstinence rates of 46 percent in newly initiated patients and 57 percent in patients who continued from the original trial. Craving scores tended to be lower in people with longer treatment durations. [3]
Manufacturer data also show that in a study of patients receiving SUBLOCADE plus counseling, 28 percent achieved treatment success. Treatment success was defined as being free of illicit opioids for at least 80 percent of study weeks, compared with 2 percent success in people receiving placebo plus counseling. [5]
Clinical summaries highlight that Sublocade can reduce cravings and withdrawal symptoms and lower the chance of dropping out of treatment when compared with some daily regimens. [1]
More than 350,000 people in the United States have been prescribed SUBLOCADE from March 2018 through early 2025, based on shipped or pharmacy filled units. This reflects growing acceptance of long acting injectable Sublocade treatment in routine care. [5]
What to expect with monthly Sublocade injections
Understanding the practical details of Sublocade can make the process feel more manageable and predictable.
Induction and stabilization
You usually begin with a short induction period on sublingual buprenorphine to stabilize withdrawal and cravings. Once your provider determines that you are stable, you transition to your first Sublocade injection. [3]
For some people, this induction and first injection can now happen on the same day using the newer same day start protocol. Your provider will guide you on which approach is safest in your situation. [4]
Dosing schedule
Typical Sublocade treatment starts with:
- 300 mg once a month for the first two months
- Then either 100 mg or 300 mg once a month, depending on your response and needs
Your provider will decide the right maintenance dose as part of your overall medication stabilization for opioid addiction plan. In clinical practice, some people stay on Sublocade for at least a year or longer when it continues to help them maintain recovery. [3]
Injection sites and procedure
Sublocade is given as a subcutaneous injection by a trained healthcare professional. The medication can be injected into four different body areas:
- Abdomen
- Buttock
- Thigh
- Back of the upper arm
It is recommended that providers rotate injection sites each month to help manage local discomfort. [4]
The injection itself is usually brief. You will remain in the clinic for a short time afterward so staff can monitor how you feel and answer any questions.
How long Sublocade stays in your system
Because Sublocade is a long acting formulation, buprenorphine from the injection remains in your system for weeks. The exact duration depends on:
- How long you have been on treatment
- Your dose
- Your individual metabolism
Even after stopping injections, buprenorphine can continue to be released from the depot for some time. This slow decline can sometimes help ease the transition if you and your provider decide to adjust or eventually taper your medication. [6]
Benefits of long acting injectable Sublocade treatment
People choose Sublocade for many reasons related to convenience, privacy, structure and symptom control.
Convenience and consistency
The once monthly injection schedule means you do not have to remember a daily dose, handle medication at home or worry about running short between refills. The steady release of buprenorphine helps prevent the peaks and valleys in blood levels that can happen with some shorter acting forms, which may reduce breakthrough cravings. [6]
Lower diversion and misuse risk
Since Sublocade is only administered in a healthcare setting through the REMS program and forms a solid depot under the skin, it cannot be easily diverted, lost, sold or misused. This structure can be particularly helpful if you have had difficulty managing take home medications or if there are safety concerns at home. [1]
Reduced stigma and more privacy
Fewer pharmacy trips and no daily visible medication can lessen feelings of stigma for some people. It may also make it easier to maintain employment, attend school or manage family responsibilities while staying engaged in care at an opioid medication treatment clinic. Sublocade can support reintegration into normal activities by reducing the need for frequent urine drug screening in some models of care, although testing remains an important tool for many programs. [3]
Support for long term recovery
The long acting nature of Sublocade allows treatment teams to focus more on counseling, mental health, relationships and rebuilding your life, instead of focusing primarily on daily dosing logistics. That shift can strengthen the overall opioid addiction medication management plan that surrounds your medication.
Possible side effects and safety considerations
Like any medication, Sublocade has potential side effects and safety concerns that you should discuss with your provider before starting treatment.
Common side effects
In clinical studies and post marketing experience, common side effects of Sublocade include:
- Constipation
- Headache
- Nausea or vomiting
- Tiredness
- Injection site pain, itching or tenderness
- Increased liver enzymes
These side effects were usually mild to moderate. Injection site reactions were the most frequent issues, and serious adverse events occurred in about 3 to 4 percent of patients, including some liver related events that led to dose changes. [7]
Your provider will typically check your liver function before starting Sublocade and periodically during treatment. If you notice jaundice, severe abdominal pain or dark urine, you should contact your provider right away.
Serious risks and precautions
Sublocade is an opioid medication, so it still carries some risk of respiratory depression, particularly if combined with other central nervous system depressants such as benzodiazepines, alcohol or sedatives. Your provider will review all of your medications and substance use as part of careful opioid dependence medication program planning.
Sublocade is not recommended for women of childbearing potential who are not using effective contraception, due to potential risks to a developing fetus. It should only be used in pregnancy under very careful specialist guidance. [3]
Because the medication forms a solid depot, it must never be injected into a vein. Sublocade is only administered by trained professionals to prevent this and other complications. [1]
Cost, access, and support
Insurance coverage for Sublocade varies, but many commercial plans and public programs cover it when it is medically indicated. For some people, this can make it comparable in cost to other MAT options.
The SUBLOCADE Copay Assistance Program can help with out of pocket medication costs for many eligible patients, although it does not cover office visits or injection administration fees. About 95 percent of participants in the copay program have their medication costs covered, subject to eligibility and program terms. [4]
Some treatment centers, such as programs described by CT Addiction Medicine, note that insurance often covers Sublocade when it is part of a comprehensive recovery plan that includes counseling and therapy. [6]
If you are already engaged in a methadone clinic treatment program, suboxone treatment program outpatient or other outpatient opioid medication treatment, your team can help you explore whether long acting injectable Sublocade treatment is available in your area and whether it fits your coverage and financial situation.
Sublocade is not a quick fix or a stand alone solution. It is one component of a larger recovery plan that includes counseling, support and ongoing medical care.
Deciding if Sublocade is right for you
Choosing between methadone, Suboxone, Subutex and Sublocade is a personal decision that should be made with a provider who understands your history and goals. In a structured opioid medication treatment clinic, you can expect your team to:
- Review your past treatment attempts and responses
- Assess your current opioid use, other substances and medical conditions
- Discuss your lifestyle, schedule and support system
- Explain how each medication works and what treatment looks like day to day
- Help you weigh the advantages and limitations of long acting injectable Sublocade treatment versus daily medications
For some people, the structure of methadone or the flexibility of Suboxone will be the best fit. For others, monthly Sublocade injections provide the stability and simplicity they need to stay engaged in recovery. With careful medication stabilization for opioid addiction and ongoing support, each of these evidence based options can play a powerful role in helping you move away from opioid use and toward a healthier, more stable life.
