Addiction, Abuse, and MisuseBuprenorphine exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death. Assess each patient's risk prior to prescribing buprenorphine, and monitor all patients regularly for the development of these behaviors or conditions.Opioid Analgesic Risk Evaluation and Mitigation Strategy (REMS)To ensure that the benefits of opioid analgesics outweigh the risks of addiction, abuse and misuse, the Food and Drug Administration (FDA) has required a REMS for these products. Under the requirements of the REMS, drug companies with approved opioid analgesic products must make REMS-compliant education programs available to healthcare providers. Healthcare providers are strongly encouraged to: complete a REMS-compliant education program, counsel patients and/or their caregivers, with every prescription, on safe use, serious risks, storage, and disposal of these products, emphasize to patients and their caregivers the importance of reading the Medication Guide every time it is provided by their pharmacists, and consider other tools to improve patient, household, and community safety.Life-Threatening Respiratory DepressionSerious, life-threatening, or fatal respiratory depression may occur with use of buprenorphine. Monitor for respiratory depression, especially during initiation of buprenorphine or following a dose increase. Misuse or abuse of buprenorphine by chewing, swallowing, snorting or injecting buprenorphine extracted from the buccal film will result in the uncontrolled delivery of buprenorphine and pose a significant risk of overdose and death.Accidental ExposureAccidental exposure to even one dose of buprenorphine, especially by children, can result in a fatal overdose of buprenorphine.Neonatal Opioid Withdrawal SyndromeProlonged use of buprenorphine during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available.Risks from Concomitant Use with Benzodiazepines or Other CNS DepressantsReserve concomitant prescribing of buprenorphine and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation.

QT prolongation has been observed. In clinical trials of buprenorphine (the active ingredient contained in Belbuca) buccal film (n=1590), post-baseline QTcF values of 450 to 480 milliseconds were observed in 2% of patients at doses up to 900 mcg every 12 hours. In a QT study in healthy subjects, therapeutic doses (10 mcg/hour transdermal patch) had no effect on the QTc interval, but higher doses (40 mcg/hour) were associated with a mean prolongation of 5.9 milliseconds.
During clinical trials, serial ECGs were collected to evaluate the effect of extended-release subcutaneous administration of buprenorphine on QT prolongation. Seven patients showed a greater than 60 msec increase QTc from baseline. One patient had a QTc greater than 500 msec. These QTc findings were reported as sporadic and transient and none led to aberrant ventricular rhythm. Review of ECG and adverse event data showed no evidence of syncope, seizure, or ventricular tachycardia or fibrillation.
