IMPORTANT: Keep buprenorphine and naloxone sublingual tablets 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 takes buprenorphine and naloxone sublingual tablets, 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 buprenorphine and naloxone sublingual tablets?

  • Buprenorphine and naloxone sublingual tablets contain a medicine called buprenorphine. Buprenorphine is an opioid that can cause serious and life-threatening breathing 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 buprenorphine and naloxone sublingual tablets 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.
  • Buprenorphine and naloxone sublingual tablets 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 buprenorphine and naloxone sublingual tablets with certain medicines. Taking buprenorphine and naloxone sublingual tablets 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 (“shootup”) buprenorphine and naloxone sublingual tablets. Injecting buprenorphine and naloxone sublingual tablets may cause life‐threatening infections and other serious health problems. Injecting buprenorphine and naloxone sublingual tablets may cause sudden serious withdrawal symptoms such as pain, cramps, vomiting, diarrhea, anxiety, sleep problems, and cravings.
  • Do not switch from buprenorphine and naloxone sublingual tablets to other medicines that contain buprenorphine without talking with your healthcare provider. The amount of buprenorphine in a dose of buprenorphine and naloxone sublingual tablets is not the same as in other medicines that contain buprenorphine. Your healthcare provider will prescribe a starting dose of buprenorphine and naloxone sublingual tablets that may be different than other buprenorphine containing medicines you may have been taking.
  • Do not stop taking buprenorphine and naloxone sublingual tablets 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 emergency department staff that you are physically dependent on an opioid and are being treated with buprenorphine and naloxone sublingual tablets.
  • Never give anyone else your buprenorphine and naloxone sublingual tablets. They could die from taking it. Selling or giving away buprenorphine and naloxone sublingual tablets is against the law.
  • Store buprenorphine and naloxone sublingual tablets securely, out of sight and reach of children, and in a location not accessible by others, including visitors to the home.
