5.12 Impairment of Ability to Drive or Operate Machinery
BUNAVAIL buccal film may impair the mental or physical abilities required for the performance of potentially dangerous tasks such as driving a car or operating machinery, especially during treatment induction and dose adjustment. Patients should be cautioned about driving or operating hazardous machinery until they are reasonably certain that BUNAVAIL buccal film therapy does not adversely affect his or her ability to engage in such activities.
5.13 Orthostatic Hypotension
Like other opioids, BUNAVAIL buccal film may produce orthostatic hypotension in ambulatory patients.
5.14 Elevation of Cerebrospinal Fluid Pressure
Buprenorphine, like other opioids, may elevate cerebrospinal fluid pressure and should be used with caution in patients with head injury, intracranial lesions, and other circumstances when cerebrospinal pressure may be increased. Buprenorphine can produce miosis and changes in the level of consciousness that may interfere with patient eva luation.
5.15 Elevation of Intracholedochal Pressure
Buprenorphine has been shown to increase intracholedochal pressure, as do other opioids, and thus should be administered with caution to patients with dysfunction of the biliary tract.
5.16 Effects in Acute Abdominal Conditions
As with other opioids, buprenorphine may obscure the diagnosis or clinical course of patients with acute abdominal conditions.
5.17 General Precautions
BUNAVAIL buccal film should be administered with caution in debilitated patients and those with myxedema or hypothyroidism, adrenal cortical insufficiency (e.g., Addison’s disease); CNS depression or coma; toxic psychoses; prostatic hypertrophy or urethral stricture; acute alcoholism; delirium tremens; or kyphoscoliosis.
6 ADVERSE REACTIONS
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
6.1 Adverse Events in Clinical Trials
The safety of BUNAVAIL buccal film is supported by clinical trials using buprenorphine and naloxone sublingual tablets, and other trials using buprenorphine tablets and buprenorphine sublingual solutions, as well as an open-label study in 249 patients treated with BUNAVAIL buccal film. In total, safety data from clinical studies are available from over 3000 opioid-dependent subjects exposed to buprenorphine at doses in the range used in the treatment of opioid addiction. Few differences in the adverse event profile were noted among buprenorphine and naloxone sublingual tablets, buprenorphine sublingual tablets and a buprenorphine ethanolic sublingual solution.
The safety and tolerability of BUNAVAIL was eva luated in a 12-week clinical study of BUNAVAIL in 249 opioid-dependent subjects stabilized on buprenorphine and naloxone sublingual tablet or film dosages of buprenorphine 8-32 mg/day.
The following adverse reactions were reported to occur by at least 5% of patients in a 12-week study with BUNAVAIL: drug withdrawal syndrome, lethargy and headache.
The adverse reactions listed below represent those that were reported by >1%, but less than 5% of patients from the 12-week clinical trial while receiving BUNAVAIL. Events are classified by system organ class. |
