Generic name: buprenorphine

What is Sublocade?

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.

It is not known if Sublocade is safe or effective in children.

Sublocade is a controlled substance (CIII) because it contains buprenorphine that can be a target for people who abuse prescription medicines or street drugs.

What is the most important information I should know about Sublocade?

  • 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
    • have mental changes such as confusion
    • have slower breathing than you normally have
    • have severe sleepiness
    • have blurred vision
    • have problems with coordination
    • have slurred speech
    • cannot think well or clearly
    • have a high body temperature
    • have slowed reflexes
    • feel agitated
    • have stiff muscles
    • have trouble walking

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

  • Death or serious harm can happen if you take anxiety medicines or benzodiazepines, sleeping pills, tranquilizers, muscle relaxants, or sedatives, antidepressants, or antihistamines, or drink alcohol during treatment with Sublocade. Tell your healthcare provider if you are taking any of these medicines and if you drink alcohol.

Who should not take Sublocade?

Do not use Sublocade if you are allergic to buprenorphine or any ingredient in the prefilled syringe (ATRIGEL delivery system). See the end of this Medication Guide for a list of ingredients in Sublocade.

What should I tell my healthcare provider before taking Sublocade?

Sublocade may not be right for you. Before starting Sublocade, tell your healthcare provider about all of your medical conditions, including:

  • Trouble breathing or lung problems
  • An enlarged prostate gland (men)
  • A head injury or brain problem
  • Problems urinating
  • A curve in your spine that affects your breathing (scoliosis)

  • Addison's disease
  • Low thyroid hormone levels (hypothyroidism)
  • A history of alcoholism
  • Mental problems such as hallucinations (seeing or hearing things that are not there).
  • Are pregnant or plan to become pregnant. If you receive Sublocade while pregnant, your baby may have symptoms of opioid withdrawal at birth.
  • Are breastfeeding or plan to breastfeed. Sublocade can pass into your breast milk and may harm your baby. Talk with your healthcare provider about the best way to feed your baby during treatment with Sublocade. Watch your baby for increased drowsiness and breathing problems.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins and herbal supplements. Sublocade may affect the way other medicines work and other medicines may affect how Sublocade works. Some medicines may cause serious or life-threatening medical problems when taken with Sublocade.

  • The doses of certain medicines may need to be changed if used during treatment with Sublocade. Do not take any medicine during treatment with Sublocade until you have talked with your healthcare provider. Your healthcare provider will tell you if it is safe to take other medicines during treatment with Sublocade.
  • You should not take anxiety medicines or benzodiazepines (such as Valium or Xanax), sleeping pills, tranquilizers, muscle relaxants, or sedatives (such as Ambien), antidepressants, or antihistamines that are not prescribed to you during treatment with Sublocade, as this can lead to slowed breathing, drowsiness, delayed reaction time, loss of consciousness or even death. If a healthcare provider is considering prescribing such a medicine for you, remind the healthcare provider that you are being treated with Sublocade.
  • You may have detectable levels of Sublocade in your body for a long period after stopping treatment with Sublocade.

Know the medicines you take. Keep a list of them to show your healthcare provider and pharmacist each time you get a new medicine.

How should I take Sublocade?

  • You will receive Sublocade by your healthcare provider as an injection just under the skin (subcutaneous) of your stomach (abdomen). You will receive Sublocade monthly (with at least 26 days between doses).
  • Sublocade is injected as a liquid. After the injection, Sublocade changes to a solid form called a depot. The depot may be seen or felt as a small bump under your skin at the injection site on your abdomen for several weeks. The depot will get smaller over time.
  • Do not try to remove the depot.
  • Do not rub or massage the injection site.
  • Try not to let belts or clothing waistbands rub against the injection site.

  • 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.
