IMPORTANT: Keep BUNAVAIL in a secure place away from children. Accidental use by a child is a medical emergency and can result in death. If a child accidentally uses BUNAVAIL, get emergency help or call 911 right away. Tell your healthcare provider if you are living in a household where there are small children.
What is the most important information I should know about BUNAVAIL?
  • BUNAVAIL contains a medicine called buprenorphine. Buprenorphine is an opioid that can cause serious and life-threatening problems, especially if you take or use certain other medicines or drugs.
  • Talk to your healthcare provider about naloxone. Naloxone is a medicine that is available to patients for the emergency treatment of an opioid overdose, including accidental use of BUNAVAIL by a child. If naloxone is given, you must call 911 or get emergency medical help right away to treat an overdose or accidental use of an opioid.
  • BUNAVAIL may cause serious and life-threatening breathing problems. Get emergency help right away if you:
  • feel faint
  • feel dizzy
  • are confused
  • feel sleepy or uncoordinated
  • have blurred vision
  • have slurred speech
  • are breathing slower than normal
  • cannot think well or clearly
  • Do not take BUNAVAIL with certain medicines. Taking BUNAVAIL with other opioid medicines, benzodiazepines, alcohol, or other central nervous system depressants (including street drugs) can cause severe drowsiness, decreased awareness, breathing problems, coma, and death.
  • Do not inject ("shoot-up") BUNAVAIL. Injecting BUNAVAIL may cause life-threatening infections and other serious health problems. Injecting BUNAVAIL may cause sudden serious withdrawal symptoms such as pain, cramps, vomiting, diarrhea, anxiety, sleep problems, and cravings.
  • Do not switch from BUNAVAIL to other medicines that contain buprenorphine without talking to your healthcare provider. The amount of buprenorphine in a dose of BUNAVAIL may not be the same as in other medicines that contain buprenorphine. Your healthcare provider will prescribe a starting dose of BUNAVAIL that may be different than other buprenorphine containing medicines you may have been taking.
  • Do not stop taking BUNAVAIL suddenly. You could become sick and have withdrawal symptoms because your body has become used to the medicine (physical dependence). Physical dependence is not the same as drug addiction.
  • In an emergency, have family members tell the emergency department staff that you are physically dependent on an opioid and are being treated with BUNAVAIL.
  • Never give anyone else your BUNAVAIL. They could die from taking it. Selling or giving away BUNAVAIL is against the law.
  • Store BUNAVAIL securely, out of sight and reach of children, and in a location not accessible by others, including visitors to the home.
  • BUNAVAIL is a prescription medicine used to treat opioid addiction in adults and is part of a complete treatment program that also includes counseling and behavioral therapy.
Who should not take BUNAVAIL?
  • Do not take BUNAVAIL if you are allergic to buprenorphine or naloxone.
Before taking BUNAVAIL, tell your healthcare provider about all of your medical conditions, including if you have:
  • trouble breathing or lung problems
  • a curve in your spine that affects your breathing
  • Addison's disease
  • an enlarged prostate (men)
  • problems urinating
  • liver, kidney, or gallbladder problems
  • alcoholism
  • a head injury or brain problem
  • mental health problems
  • adrenal gland or thyroid gland problems
Tell your healthcare provider if you are:
  • pregnant or plan to become pregnant. If you take BUNAVAIL while pregnant, your baby may have symptoms of opioid withdrawal at birth that could be life-threatening if not recognized and treated. Talk to your healthcare provider if you are pregnant or plan to become pregnant.
  • breastfeeding. BUNAVAIL can pass into your breast milk and harm your baby. Talk to your healthcare provider about the best way to feed your baby if you take BUNAVAIL. Monitor your baby for increased drowsiness and breathing problems if you breastfeed during treatment with BUNAVAIL.
Tell your healthcare provider about all of the medicines you take, including prescription and over-the-counter medicines, vitamins, or herbal supplements.
How should I take BUNAVAIL?

What should I avoid while taking BUNAVAIL?
