Belbuca and Lactation

Tell your doctor if you are breastfeeding or plan to breastfeed. The active ingredient in Belbuca, buprenorphine, has been detected in breast milk. Because of the potential for serious adverse effects in the nursing infant, breastfeeding is not recommended during treatment with Belbuca.

Belbuca Dosage

Take Belbuca exactly as prescribed by your doctor. Follow the directions on your prescription label carefully.

The Belbuca dose your doctor recommends will be based on the following: 

  • the condition being treated and the severity of your pain
  • other medical conditions you have
  • other medications you are taking or have taken for pain
  • how you respond to this medication

The recommended starting dose for a patient that has not been taking opioid medications is one 75 mcg film once daily or, if tolerated, every 12 hours for at least 4 days, then increase dose to 150 mcg every 12 hours. The dose may be gradually increased to a dose that provides adequate pain relief and minimizes adverse reactions should proceed in increments of 150 mcg every 12 hours, no more frequently than every 4 days.

The maximum Belbuca dose is 900 mcg every 12 hours.

Indications and Usage for Belbuca

Belbuca is indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate.

Limitations of  Use

  • Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses, and because of the greater risks of overdose and death with long-acting opioid formulations [see Warnings and Precautions (5.1)], reserve Belbuca for use in patients for whom alternative treatment options (e.g., non-opioid analgesics or immediate-release opioids) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain.
  • Belbuca is not indicated as an as-needed (prn) analgesic.
