Buprenorphine Side Effects - for the Professional
Buprenorphine
The most frequent side effect in clinical studies involving 1,133 patients was sedation which occurred in approximately two-thirds of the patients. Although sedated, these patients could easily be aroused to an alert state.
Other less frequent adverse reactions occurring in 5 to 10% of the patients were:
Nausea Dizziness/Vertigo
Occurring in 1 to 5% of the patients:
Sweating Headache
Hypotension Nausea/Vomiting
Vomiting Hypoventilation
Miosis
The following adverse reactions were reported to have occurred in less than 1% of the patients:
CNS Effect: confusion, blurred vision, euphoria, weakness/fatigue, dry mouth, nervousness, depression, slurred speech, paresthesia.
Cardiovascular: hypertension, tachycardia, bradycardia.
Gastrointestinal: constipation.
Respiratory: dyspnea, cyanosis.
Dermatological: pruritus.
Ophthalmological: diplopia, visual abnormalities.
Miscellaneous: injection site reaction, urinary retention, dreaming, flushing/warmth, chills/cold, tinnitus, conjunctivitis, Wenckebach block, and psychosis.
Other effects observed infrequently include malaise, hallucinations, depersonalization, coma, dyspepsia, flatulence, apnea, rash, amblyopia, tremor, and pallor.
The following reactions have been reported to occur rarely: loss of appetite, dysphoria/agitation, diarrhea, urticaria, and convulsions/lack of muscle coordination.
Allergic Reactions: Cases of acute and chronic hypersensitivity to Buprenorphine have been reported in clinical trials and in the postmarketing experience of Buprenorphine and other Buprenorphine-containing products. The most common signs and symptoms include rashes, hives, and pruritus. Cases of bronchospasm, angioneurotic edema, and anaphylactic shock have been reported. A history of hypersensitivity to Buprenorphine is a contraindication to Buprenorphine HCl.
In the United Kingdom, Buprenorphine HCl was made available under monitored release regulation during the first year of sale, and yielded data from 1,736 physicians on 9,123 patients (17,120 administrations). Data on 240 children under the age of 18 years were included in this monitored release program. No important new adverse effects attributable to Buprenorphine HCl were observed.

TopSide Effects by Body System
General
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). Sublingual buprenorphine may cause withdrawal symptoms in opioid dependent patients.
Chronic administration of buprenorphine may result in dependence and withdrawal symptoms may occur upon abrupt withdrawal. Buprenorphine may also cause withdrawal symptoms if administered to opioid-dependent patients.
Nervous system
Nervous system side effects associated with parenteral buprenorphine have most commonly included sedation (60%). Dizziness, vertigo, headache have been reported in 5% to 10% of patients. Confusion, weakness, fatigue, nervousness, slurred speech, and paresthesia have been reported in less than 1% of patients. Buprenorphine may elevate cerebrospinal fluid pressure and produce changes in the level of consciousness. Somnolence, tinnitus, agitation, tremor, coma, and convulsions have also been reported.
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). Side effects associated with buprenorphine alone have included anxiety, depression, dizziness, insomnia, nervousness, somnolence, and elevated cerebrospinal fluid pressure.
Respiratory
Respiratory system side effects have included respiratory depression with therapeutic doses of injectable and sublingual buprenorphine. Death has occurred with intravenous misuse of buprenorphine, usually with concurrent benzodiazepines, alcohol, and/or other CNS depressants. Hypoventilation (1% to 5%), dyspnea (<1%), cyanosis (<1%), and apnea (<1%) have also been reported.
Respiratory system side effects in opioid dependent patients have included rhinitis (4.7% vs 13.1% with placebo) and respiratory depression, particularly after intravenous administration. Sublingual buprenorphine has been implicated in a case of noncardiogenic pulmonary edema. Death has occurred with intravenous misuse of buprenorphine, usually with concurrent benzodiazepines, alcohol, and/or other CNS depressants.
Gastrointestinal
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.
Hypersensitivity
Hypersensitivity reactions associated with buprenorphine have included rash, hives, pruritus, bronchospasm, angioneurotic edema, and anaphylactic shock.
Other
Neonatal withdrawal has been reported in infants of women who took buprenorphine during pregnancy.
Cardiovascular
Cardiovascular side effects in opioid dependent patients have included vasodilation (9.3% vs 6.5% with placebo). Buprenorphine may cause orthostatic hypotension. Misuse of crushed buprenorphine tablets by inhalation has been associated with chest pain and acute anterior myocardial infarction in a 22-year-old male.
Endocrine
Endocrine effects have included sweating (sublingual in opioid dependent patients, 14% vs. 10.3% with placebo; parenteral for analgesia, 1% to 5%).
Ocular
Ocular side effects have included blurred vision, conjunctivitis, amblyopia, and miosis.
Psychiatric
Psychiatric side effects associated with parenteral buprenorphine have included euphoria, depersonalization, depression, dreaming, and psychosis in less than 1% of patients. Dysphoria has been reported rarely. Auditory and visual hallucinations have been associated with parenteral and sublingual buprenorphine.
