The most commonly reported adverse reactions have included respiratory depression, bradycardia, hypotension, and skeletal muscle rigidity. In pediatric patients, the most commonly reported events were nausea, vomiting, and shivering.

Cough, dyspnea, bronchospasm, laryngospasm, rhonchi, stridor, nasal congestion, pharyngitis, pleural effusion, hiccups, pulmonary edema, rales, bronchitis, and rhinorrhea have been reported in less than 1% of patients.

Common (1% to 10%): Respiratory depression

Uncommon (0.1% to 1%): Apnea, hypoxia

Frequency not reported: Cough, dyspnea, bronchospasm, laryngospasm, rhonchi, stridor, nasal congestion, pharyngitis, pleural effusion, hiccups, pulmonary edema, rales, bronchitis, rhinorrhea

Opioids:

Frequency not reported: Serious respiratory depression

Cardiovascular side effects such as hypotension and bradycardia have been reported to occur most frequently during the induction and maintenance period. Bradycardia and hypotension are probably due to a centrally mediated increase in vagal nerve activity. Glycopyrrolate, atropine and/or ephedrine may be useful in treating these effects. Unlike morphine, decreases in blood pressure are not due to histamine release.

In male patients and in those patient older 65 years, the incidence of hypotension is higher. Various atrial and ventricular arrhythmias, heart block, ECG change consistent with myocardial ischemia, elevated CPK-MB level, and syncope have been reported in less than 1% of patients.

Very common (10% or more): Hypotension (up to 19%)

Common (1% to 10%): Bradycardia, atrial fibrillation, atrial flutter, myocardial ischemia, edema, flushing

Uncommon (0.1% to 1%): Decreased cardiac output

Nausea has been reported to occur in very commonly, especially when used as a postoperative analgesic and upon discontinuation. Abdominal discomfort, xerostomia, gastro-esophageal reflux, dysphagia, diarrhea, and ileus have been reported in less than 1% of patients.

Rigidity may be lessened by concomitant administration of a muscle relaxant. Muscle stiffness and musculoskeletal chest pain have been reported in less than 1% of patients.
