Sublocade (buprenorphine) for addiction: Dosage, Side Effects & Pregnancy Safety

What is Sublocade (buprenorphine) and how is it used?

Sublocade is a prescription medicine used to treat adults with moderate to severe addiction (dependence) to opioid drugs (prescription or illegal) who:

  • have received treatment with an oral transmucosal (used under the tongue or inside the cheek) buprenorphine containing medicine for 7 days and
  • are taking a dose that controls withdrawal symptoms for at least seven days.
  • Sublocade is part of a complete treatment plan that should include counseling.

What are the most important side effects and other facts about Sublocade (buprenorphine)?



  • Serious harm or death could result if administered intravenously. Sublocade forms a solid mass upon contact with body fluids and may cause occlusion, local tissue damage, and thrombo-embolic events, including life threatening pulmonary emboli, if administered intravenously. 
  • Because of the risk of serious harm or death that could result from intravenous self administration, Sublocade is only available through a restricted program called the Sublocade REMS Program. Healthcare settings and pharmacies that order and dispense Sublocade must be certified in this program and comply with the REMS requirements. 
  • Because of the serious risk of potential harm or death from self-injecting Sublocade into a vein (intravenously), it is only available through a restricted program called the Sublocade REMS Program.
    • Sublocade is not available in retail pharmacies.
    • Your Sublocade injection will only be given to you by a certified healthcare provider.
  • In an emergency, you or your family should tell the emergency medical staff that you are physically dependent on an opioid and are being treated with Sublocade.
  • Buprenorphine, the medicine in Sublocade, can cause serious and life-threatening problems, especially if you take or use certain other medicines or drugs. Call your healthcare provider right away or get emergency help if you:
    • feel faint or dizzy
    • cannot think well or clearly
    • have mental changes such as confusion
    • have a high body temperature
    • have slower breathing than you normally have
    • have slowed reflexes
    • have severe sleepiness
    • feel agitated
    • have blurred vision
    • have stiff muscles
    • have problems with coordination
    • have trouble walking
    • have slurred speech

These can be signs of an overdose or other serious problems.

What should I avoid while being treated with Sublocade?

  • Do not drive, operate heavy machinery, or perform any other dangerous activities until you know how this medicine affects you. Buprenorphine can cause drowsiness and slow reaction times. This may happen more often in the first few days after your injection and when your dose is changed.
  • Do not drink alcohol during treatment with Sublocade, as this can lead to slowed breathing, drowsiness, slow reaction time, loss of consciousness or even death.
