    These are not all the possible side effects of SUBLOCADE.

    Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1‑800‑FDA‑1088.


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 should I tell my healthcare provider before starting 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)
  • Liver problems
  • Gallbladder problems
  • Adrenal gland problems
  • 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.

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.

How soon can someone start SUBLOCADE?

If a healthcare provider decides SUBLOCADE is an appropriate option, a patient must receive treatment with an oral transmucosal (used under the tongue or inside the cheek) buprenorphine-containing medicine for 7 days and must be taking a dose that controls withdrawal symptoms for at least seven days. Following this period SUBLOCADE will be given by their healthcare provider as an injection just under the skin (subcutaneous) of their stomach (abdomen).

Can someone get SUBLOCADE at a pharmacy?

No, SUBLOCADE is not available in retail pharmacies. SUBLOCADE must be prescribed, obtained, and administered by a healthcare provider. If the healthcare provider practices in an office‑based setting, then he/she must be waivered to prescribe SUBLOCADE.

What if a dose of SUBLOCADE is missed?

If a dose is missed, the next dose should be received as soon as possible, with the following dose given at least 26 days later. See a healthcare provider to receive a SUBLOCADE injection as soon as possible.

How long will a person be on SUBLOCADE?

Everyone is different. A healthcare provider should monitor treatment and overall progress to help determine how long a patient will need treatment with SUBLOCADE.

Is SUBLOCADE addictive?

Yes, SUBLOCADE contains buprenorphine, a Schedule III controlled substance that can be abused in the same way as other opioids. It could be a target for people who abuse prescription medicines or street drugs.

How is SUBLOCADE different from other opioids?

Buprenorphine helps the brain get used to functioning without illicit opioids. At prescribed doses, it's designed to have a weaker effect on the brain compared to illicit opioids and not cause a "high." These doses may help reduce cravings, while blocking other opioids from causing rewarding effects. This can make taking them less appealing.

What results have people experienced while on SUBLOCADE?

In a clinical study, SUBLOCADE patients were 14x* more likely to achieve treatment success.

*28% of people with SUBLOCADE plus counseling compared to 2% of people with placebo plus counseling.

In a 24‑week study, treatment success was defined as opioid‑free at least 80% of the weeks in treatment. Opioid‑free means urine sample tested negative for illicit opioids plus no self-reported use of opioids. Weeks were not always consecutive.

During the dosing period, SUBLOCADE:

  • Continuously releases buprenorphine all month with no real daily ups and downs.
  • Sustains the therapeutic level of buprenorphine throughout the month.
  • Blocks the rewarding effects of opioids, which are the "pleasurable feelings" that can keep people using.
  • Is part of a complete treatment plan that should include counseling. The role of counseling is to help patients manage emotions and behaviors that can be linked to opioid addiction.

In a 12‑week study of 39 non‑treatment‑seeking adults, SUBLOCADE blocked the rewarding effects of opioids.

How frequently will SUBLOCADE be given?

SUBLOCADE is a once‑monthly injection. Counseling should also be part of a treatment plan. Work with your treatment team to decide how frequently you should go to counseling.

Will an appointment be needed to have SUBLOCADE removed at the end of the month?

No. SUBLOCADE dissolves in your body over a period of time. When a person receives a SUBLOCADE injection, medication is gradually released into the bloodstream over time.

What happens if my treatment provider lowers my dose?

SUBLOCADE comes in 2 doses: 300 mg and 100 mg. Your treatment provider will start with 300 mg to help the medication reach an effective level in your body. After 2 months, you may receive a lower "maintenance dose" of 100 mg or stay on 300 mg. Your treatment provider will decide what's best.

The level of medicine in your blood is important. Ask your treatment provider about how the delivery system used in SUBLOCADE maintains medicine levels even when the dose is lowered.


Why is counseling with SUBLOCADE important?

Treatment that combines medication and counseling has been shown to be effective, because addiction is a disease that impacts a person’s behaviors.

Counseling can help people deal with the behaviors and emotions that are often linked to addiction. It can also teach long‑term skills to cope with stressful situations and help people start positive routines.

How can I find support groups?

Ask a healthcare provider for a recommendation, or visit a resource like the Substance Abuse and Mental Health Services Administration website and use its Behavioral Health Treatment Services Locator.

Support groups may have a digital presence. Online support groups may also be an option.

Opioid addiction/Opioid Use Disorder (OUD)

What are the possible signs of Opioid Use Disorder?

Only a healthcare provider can diagnose Opioid Use Disorder. The list below includes some possible signs of the disease, but it’s important to see a healthcare provider for a diagnosis.

  • Needing to take more of the drug to get the same effect*
  • Experiencing withdrawal symptoms when not using opioids*
  • Taking larger amounts of opioids than planned, and for longer periods of time

How can someone deal with relapse?

If a person experiences a relapse, he/she should talk to a healthcare provider. Together they can work on a plan of action to get him/her back on track.

Remember, there can be setbacks in treatment or relapse, but don’t give up. It’s possible to keep moving towards recovery.

What is withdrawal?

When someone uses a substance and becomes dependent or addicted, trying to stop can cause negative emotions and physical symptoms. Physical symptoms can include nausea, vomiting, muscle aches, and cramping.

What are the rewarding effects of opioids?

The rewarding effects of opioids are the pleasurable effects also known as the "relaxed feeling" or "high" that can keep people using.

What are triggers?

Triggers are external events or situations that can make you want to use. Triggers can include people, places, or things.

Can OUD be cured?

OUD is a chronic disease that physically changes the brain. While there is no cure, it can be treated and managed long-term. Learn why it's so hard to quit.

Who can diagnose OUD?

Only a healthcare provider can diagnose Opioid Use Disorder (OUD).
