Side effects affecting the body as a whole in opioid dependent patients have included asthenia (6.5% vs 6.5% with placebo), chills (7.5% vs 7.5% with placebo), headache (36.4% vs 22.4% with placebo), infection (5.6% vs 6.5% with placebo), pain (22.4% vs 18.7% with placebo), abdominal pain (11.2% vs 6.5% with placebo), back pain (3.7% vs 11.2% with placebo), and withdrawal syndrome (25.2% vs 37.4% with placebo).
Chronic administration of buprenorphine may result in dependence and withdrawal symptoms may occur upon abrupt withdrawal. The naloxone component may produce severe withdrawal symptoms if buprenorphine-naloxone is injected by opioid-dependent individuals. Sublingual buprenorphine-naloxone may also cause withdrawal symptoms if taken before the opioid agonist effects have subsided.
Neonatal withdrawal has been reported in infants of women who took buprenorphine during pregnancy.
Nervous system side effects in opioid dependent patients have included insomnia (14% vs 15.9% with placebo). Increased CNS depression may occur in patients receiving concurrent CNS depressants (e.g., narcotic analgesics, general anesthetics, benzodiazepines, phenothiazines, tranquilizers, sedative/hypnotics, or alcohol). Buprenorphine may elevate cerebrospinal fluid pressure. Side effects associated with buprenorphine alone have included anxiety, depression, dizziness, insomnia, nervousness, and somnolence.
Respiratory system side effects in opioid dependent patients have included rhinitis (4.7% vs 13.1% with placebo).
Respiratory depression has been associated with buprenorphine, particularly after intravenous administration. Death has occurred with intravenous misuse of buprenorphine, usually with concurrent benzodiazepines, alcohol, and/or other CNS depressants.
Gastrointestinal side effects in opioid dependent patients have included constipation (12.1% vs 2.8% with placebo), diarrhea (3.7% vs 15% with placebo), nausea (15% vs 11.2% with placebo), and vomiting (7.5% vs 4.7% with placebo). Buprenorphine may increase intracholedochal pressure.
Endocrine effects in opioid dependent patients have included sweating (14% vs 10.3% with placebo).
Hypersensitivity reactions associated with buprenorphine have included rash, hives, pruritus, bronchospasm, angioneurotic edema, and anaphylactic shock.
Misuse of crushed buprenorphine tablets by inhalation has been associated with chest pain and acute anterior myocardial infarction in a 22-year-old male.
Cardiovascular side effects in opioid dependent patients have included vasodilation (9.3% vs 6.5% with placebo). Buprenorphine may cause orthostatic hypotension.
Ocular side effects associated with buprenorphine may include miosis.
Hepatic side effects associated with sublingual buprenorphine have included cytolytic hepatitis and hepatitis with jaundice in opioid addicts. Preexisting liver dysfunction, hepatitis B or C virus infection, injectable drug use, or concomitant hepatotoxic drugs may have had contributory roles. Baseline and periodic monitoring of liver function tests is recommended during therapy. Close monitoring or careful discontinuation is recommended if a hepatic adverse reaction is suspected.
Auditory and visual hallucinations have been associated with parenteral and sublingual buprenorphine.
