Sublocade is a prescription medication used in the treatment of opioid use disorder (OUD). It contains buprenorphine, an FDA-approved partial opioid agonist that helps reduce cravings and withdrawal symptoms. Unlike daily medications, Sublocade is administered as a once-monthly injection under the skin, releasing buprenorphine steadily over time.

If you’re considering or currently taking Sublocade, you might be wondering: How Long Does Sublocade Stay In Your System?

What is Sublocade?

Sublocade is an extended-release injectable form of buprenorphine. It is typically prescribed for individuals who are already stabilized on another buprenorphine treatment (like Suboxone) and want a long-term maintenance option.

By providing a steady dose, Sublocade:

  • Reduces the risk of relapse.
  • Eliminates the need for daily dosing.
  • Improves consistency in treatment adherence.

How Long Does Sublocade Stay in the Body?

Because Sublocade is an extended-release medication, it remains in the system much longer than most other treatments. On average:

  • Half-life: Sublocade’s half-life ranges from 43 to 60 days, meaning it takes that long for half the drug to leave your system.
  • Duration in the body: It can take several months (up to 5–6 months) for Sublocade to fully clear from the body after the last injection.

This extended timeline is due to the slow release of buprenorphine from the injection site.

Factors That Affect How Long Sublocade Stays in Your System

The exact duration can vary from person to person, depending on:

  • Dosage: Higher doses may take longer to clear.
  • Length of use: Individuals on Sublocade for a longer time may have the medication present in their body for extended periods.
  • Metabolism: Each person’s liver function and metabolism affect how quickly the drug is broken down.
  • Overall health: Age, weight, and organ function can influence drug clearance.

How Long Does Sublocade Show Up on Drug Tests?

Most standard drug tests check for opioids, not buprenorphine specifically. However:

  • Buprenorphine detection: Specialized tests can detect buprenorphine.
  • Detection window: Since Sublocade remains active in the system for months, buprenorphine could be detected for an extended period depending on the test.

If you’re undergoing testing, it’s important to disclose your prescription to avoid confusion.

Why the Long Duration Matters

The fact that Sublocade stays in the body for months is both an advantage and a consideration:

  • Benefits: Provides consistent protection against cravings and relapse without daily dosing.
  • Considerations: Once injected, Sublocade cannot be removed, so individuals must be sure they are committed to this form of treatment.

Final Thoughts

So, how long does Sublocade stay in your system? In most cases, it remains detectable for several months after the last dose due to its slow-release design and long half-life.

For those in recovery, this long duration offers stability and consistency, making it an effective tool in opioid use disorder treatment. However, it also means that once started, you’ll need to work closely with your healthcare provider to manage your treatment plan.


Final Note: If you’re considering Sublocade or have questions about how it works in your system, always consult with a qualified addiction specialist or healthcare provider.
