Sublocade Shot: Uses, Benefits, and Support Resources

Searching for help with opioid treatment can feel heavy, especially when you keep finding answers that sound cold, rushed, or written for a clinic wall. The Sublocade shot may have come up during your hard search, a doctor’s visit, or my kind of quiet moment where change starts to feel necessary.

I know that kind of moment needs clear words, not judgment. You may want to know what the process feels like, what questions to ask, and how support fits around treatment.

My goal is to keep things honest, plain, and useful. Recovery is not just about medication names. It is about safety, trust, timing, and knowing where to turn when the day gets rough.

What Is the Sublocade Shot?

Sublocade is a once-monthly subcutaneous injection of buprenorphine extended-release, made by Indivior and approved by the FDA in November 2017 for adults with moderate-to-severe opioid use disorder. It contains buprenorphine only, with no naloxone, which makes it different from some other opioid treatment medicines.

By early 2026, more than 500,000 people in the United States had been prescribed Sublocade, showing how much its use has grown since its launch. The main difference is its delivery system. Instead of taking a pill or film every day, patients receive a full month of buprenorphine through one injection from a certified provider.

For many people in recovery, that can make treatment easier to stay with. According to the FDA prescribing information for Sublocade, patients should first use a buprenorphine medication for at least 7 days and receive counseling and support during treatment.

How the Sublocade Injection Works In Your Body

Sublocade uses a slow-release system that keeps buprenorphine active through the month, helping reduce cravings and withdrawal symptoms without daily dosing pressure.

1. It forms a depot under the skin: Theprovider injects Sublocade into the fatty layer under the skin of the abdomen. Once it comes into contact with body fluid, it forms a small, firm depot.
2. Releases buprenorphine slowly: The depot dissolves over about 30 days and releases buprenorphine at a steady rate. The 300 mg dose can maintain levels of around 5-6 ng/mL.
3. Binds to opioid receptors: Buprenorphine attaches to the same mu-opioid receptors affected by opioids like heroin, fentanyl, and pain pills, helping reduce cravings and withdrawal.
4. It has a ceiling effect: Buprenorphine is a partial opioid agonist, so its effects level off after a certain point. This may lower overdose risk when used as prescribed.
5. Helps smooth out highs and lows: Sublocade keeps buprenorphine levels steadier through the month, which may reduce the peaks and troughs linked with daily oral buprenorphine.

This steady monthly delivery can make treatment feel more stable, but dosing, safety, counseling, and follow-up still need medical guidance at every visit.

What to Expect: Before, During, and After Your Sublocade Injection

Knowing what happens before, during, and after the injection can make the appointment feel less intimidating and help you ask better questions before treatment begins.

Phase 1: Before the Injection

Before receiving the first Sublocade injection, patients must be stabilized on a transmucosal buprenorphine medication, such as Suboxone or Subutex, for at least 7 days. This step helps confirm that buprenorphine is well tolerated and working effectively.

The healthcare provider will review treatment progress, assess withdrawal symptoms, and verify that the current dose is stable before moving forward with the monthly injection.

Phase 2: During the Injection

The Sublocade injection is administered by a trained healthcare provider in a clinical setting and is placed into the fatty tissue of the abdomen. Most patients describe a brief stinging or burning sensation that lasts about a minute.

Some soreness may continue for a few days afterward. To improve comfort, providers may apply ice or a topical numbing agent before giving the injection.

Phase 3: After the Injection

After the injection, patients are usually monitored for a short period before leaving the clinic. A small, firm lump at the injection site is expected because the medication forms a depot under the skin.

Mild redness, itching, tenderness, or swelling around the area can occur and typically improves on its own. These reactions are usually localized and do not affect the rest of the body.

Benefits of the Sublocade Shot in Treating Opioid Addiction

The Sublocade shot may help make recovery more manageable by reducing daily medication pressure while supporting steadier treatment for opioid cravings and withdrawal symptoms.

1. Reduces cravings: Sublocade keeps buprenorphine active through the month, which may help lower opioid cravings and reduce the urge to return to use.
2. Helps control withdrawal: Steady medication release can help manage withdrawal symptoms between appointments, making treatment feel less up and down.
3. Removes daily dosing: Since Sublocade is given once a month, patients do not need to remember a pill or film every day.
4. Lowers misuse risk: Sublocade is administered by a healthcare provider and is not stored at home, which may reduce the risk of misuse, diversion, or accidental exposure.
5. Supports long-term care: Monthly visits can help patients stay connected to counseling, follow-ups, and other recovery support.

Sublocade is not a cure, but its monthly dosing and steady medication release can support recovery when paired with counseling and medical care.

Sublocade vs Suboxone: Key Differences

Both Sublocade and Suboxone contain buprenorphine and are used to treat opioid use disorder, but they differ in how they are taken, managed, and integrated into treatment plans.

1. Administration and Convenience

One of the biggest differences is how each medication is taken. Sublocade is administered once monthly by a certified healthcare provider, whereas Suboxone is usually taken daily at home.

For some people, removing the need for daily medication can make treatment feel simpler and easier to maintain over time.

2. Medication Composition

Sublocade contains only buprenorphine. Suboxone contains buprenorphine combined with naloxone, an ingredient added to discourage misuse by injection.

Both medications help reduce cravings and withdrawal symptoms, but their formulations are designed differently.

3. Flexibility and Dose Adjustments

Suboxone offers more flexibility because doses can be adjusted relatively quickly when treatment needs change.

Sublocade provides long-acting medication coverage for an entire month, which can be beneficial for stability but offers less flexibility between injections.

4. Storage and Safety Considerations

Because Suboxone is stored at home, it must be kept away from children, pets, and anyone for whom it was not prescribed. Sublocade removes that responsibility entirely since every dose stays in a clinical setting until it is administered.

People who are concerned about having controlled medication at home may find that a meaningful advantage.

Some people who are also trying to understand their other medication interactions, for example, those tracking drug interactions with Wellbutrin, may find the provider-only model simpler to manage.

5. Which Option Is Better?

There is no universal answer. The better option depends on treatment history, lifestyle, cravings, withdrawal control, insurance coverage, and personal preferences.

Some people begin treatment with Suboxone and later transition to Sublocade, while others continue doing well on daily medication for years. The right choice is the one that supports long-term recovery safely and consistently.

Quick Glance: Sublocade vs Suboxone

Side Effects and Safety: What the Full Picture Looks Like

Sublocade can be helpful in opioid use disorder treatment, but it still needs careful use. Knowing the possible side effects helps you spot what is normal and what needs medical attention.

Common Side Effects for both medications

The most common Sublocade side effects are mild and may improve as the body adjusts to treatment. These can include nausea, vomiting, constipation, headache, fatigue, drowsiness, and insomnia.

Not everyone experiences them, and some symptoms may be managed with provider-approved care, hydration, diet changes, sleep support, or follow-up adjustments.

Injection Site Reactions

Because Sublocade is given as an injection, some effects are tied to the site itself. Patients may notice redness, itching, swelling, tenderness, soreness, or a small firm nodule under the skin. That nodule is often the medication depot and is expected.

Most local reactions improve within a few days without treatment. People who have also dealt with withdrawal-related sweating from substances like alcohol may recognize some overlap in how the body reacts during early recovery.

Those managing similar symptoms can find useful context in night sweats during alcohol withdrawal.

Serious Risks and Safety Considerations

Serious reactions are uncommon, but they require prompt medical attention. Watch for severe allergic reactions, breathing problems, changes in liver function, extreme sleepiness, confusion, or difficulty staying awake.

Risk increases when Sublocade is combined with alcohol, benzodiazepines, sleep medications, or other central nervous system depressants.

People with a buprenorphine allergy, liver disease, breathing disorders, or head injuries need careful medical review before starting.

Most people tolerate Sublocade well, but safety depends on honest communication, regular follow-ups, and fast reporting of side effects that feel severe, unusual, or worsening.

Who May Be a Good Fit for Sublocade and Who May Not Be?

While only a healthcare provider can determine eligibility, the table below outlines who may be a better candidate for Sublocade and who may need a different treatment approach.

Cravings, Relapse, and Long-Term Recovery

Cravings are not a character flaw. They are tied to real brain changes, stress patterns, memory loops, chronic pain, and the environment. Medication helps because it lowers the volume on those signals, creating more room to make safer choices in the moment.

What medication cannot do is teach you how to handle a fight with your partner, a bad night’s sleep, a difficult paycheck, a lonely weekend, or a text from someone you used to use with. That is where the rest of the plan matters. A strong recovery approach often includes:

• Medication treatment: Reduces cravings and withdrawal so recovery feels more stable day to day.
• Individual therapy: Helps work through triggers, stress, trauma, and opioid-use patterns specific to your history.
• Group counseling: Builds support with people facing similar recovery challenges and reduces the isolation that often drives relapse.
• Peer support: Offers encouragement from people who understand firsthand what this process feels like.
• Outpatient programs: For many people, outpatient rehab allows treatment to continue alongside work, family, and daily life without a residential stay.
• Relapse prevention planning: Prepares you specifically for cravings, high-stress moments, and the situations that are most likely to be risky.
• Mental health treatment: Addresses anxiety, depression, trauma, or sleep problems that often run alongside opioid use disorder.
• Safe housing and routine: Creates a stable environment away from conflict, substance availability, or chaos.

Cost, Insurance, and Accessing Sublocade

Sublocade is expensive without coverage. The list price per injection can range from roughly $1,500 to $1,900 per month. Most major insurance plans, including Medicaid and Medicare, cover Sublocade for qualifying patients, though prior authorization requirements vary by state and plan.

Indivior offers the Sublocade Patient Assistance Program for people who are uninsured or underinsured. Eligibility requirements apply, and a provider can help navigate the application process.

Recovery is not a single decision. It is a process, and it almost always goes better with structured support alongside medication.

If you are looking for a Sublocade-certified provider or want to understand your treatment options, SAMHSA’s National Helpline (1-800-662-4357) is free, confidential, and available 24/7. You can also use SAMHSA’s treatment locator at findtreatment.gov to find certified providers in your area.

People managing other medications during recovery, such as those who are also prescribed antidepressants, may want to review what Wellbutrin withdrawal involves before making any changes to their treatment stack.

Frequently Asked Questions

How long does Sublocade stay in your body after the last injection?

Buprenorphine from Sublocade can remain detectable in the body for several months after the final injection, depending on dose and individual metabolism.

According to Indivior’s prescribing information, patients should inform emergency department staff that they have received Sublocade, since detectable buprenorphine levels may persist well past the last scheduled dose. This also means that withdrawal, if it occurs, may not begin immediately after stopping.

Can Sublocade affect pain management after surgery or a procedure?

Yes, and this is one of the more important practical concerns. Because buprenorphine occupies mu-opioid receptors and stays active for weeks, standard opioid pain medications may be less effective after surgery.

This does not mean pain cannot be managed, but it does mean your surgical team needs to know about Sublocade before any procedure. Tell every provider, including dentists and anesthesiologists, so they can plan accordingly.

Can Sublocade show up on a drug test?

Sublocade may appear as buprenorphine on a drug test. This is expected when the medication is properly prescribed.

If testing is required for work, legal reasons, or a treatment program, keep documentation of your prescription available so the result can be explained accurately. Standard panels do not always screen for buprenorphine, but more comprehensive tests do.

Can Sublocade interact with other medications?

Yes. Certain medications increase drowsiness or worsen respiratory depression when combined with Sublocade, including benzodiazepines, alcohol, sleep aids, and some anxiety medications.

Supplements and over-the-counter products can also interact. Tell your provider about everything you are taking before your first injection, and update them whenever anything changes.

Those also managing stimulant-related medications, such as people reviewing Adderall withdrawal symptoms, should flag all active prescriptions with their care team before starting Sublocade.

Can Sublocade be stopped after one injection?

Stopping after a single injection should still involve a conversation with your provider. The medication keeps releasing for weeks after administration, and withdrawal symptoms or cravings may return later than expected.

A safer path usually involves monitoring, support, and a plan for what to do if symptoms emerge rather than stopping without follow-up.

Can Sublocade be used during pregnancy?

This is an area where clinical practice is evolving. Emerging case data published in 2025 in peer-reviewed journals suggests that monthly buprenorphine injections have been used in pregnant patients with opioid use disorder, with outcomes tracked over more than five years of surveillance.

However, any decision about Sublocade during pregnancy requires detailed discussion with an obstetric provider and an addiction medicine specialist together. Untreated opioid use disorder in pregnancy carries serious risks, and medication options need to be weighed carefully against those risks on an individual basis.

Does Sublocade work as well as daily buprenorphine for reducing opioid use?

Clinical trial data suggests yes. In a controlled study cited by Indivior, 28 percent of patients on Sublocade plus counseling achieved the defined treatment success endpoint, compared to 2 percent on placebo plus counseling.

However, individual results vary significantly based on treatment adherence, counseling engagement, social support, and the severity of opioid use disorder before starting treatment. Medication is one part of a larger picture.

Final Verdict

Recovery decisions feel easier when the facts are clear and the next step feels less scary. I hope this helped you understand how Sublocade works, what the monthly injection may feel like, how it compares with Suboxone, and why side effects, provider visits, and support matter.

The Sublocade shot can reduce daily medication pressure, but it still works best with honest medical care, counseling, and a plan for cravings. You also saw why relapse needs a quick response, not shame.
