warnings and cautions

5.12 Abrupt Discontinuation of Esmolol Hydrochloride Severe exacerbations of angina, myocardial infarction, and ventricular arrhythmias have been reported in patients with coronary artery disease upon abrupt discontinuation of beta-blocker therapy. Observe patients for signs of myocardial ischemia when discontinuing esmolol hydrochloride. Heart rate increases moderately above pre-treatment levels 30 minutes after esmolol hydrochloride discontinuation.

warnings and cautions

5.13 Hyperkalemia Beta blockers, including esmolol hydrochloride, have been associated with increases in serum potassium levels and hyperkalemia. The risk is increased in patients with risk factors such as renal impairment. Intravenous administration of beta blockers has been reported to cause potentially life-threatening hyperkalemia in hemodialysis patients. Monitor serum electrolytes during therapy with esmolol hydrochloride.

warnings and cautions

5.14 Use in Patients with Metabolic Acidosis Beta blockers, including esmolol hydrochloride, have been reported to cause hyperkalemic renal tubular acidosis. Acidosis in general may be associated with reduced cardiac contractility.

warnings and cautions

5.15 Use in Patients with Hyperthyroidism Beta-adrenergic blockade may mask certain clinical signs (e.g., tachycardia) of hyperthyroidism. Abrupt withdrawal of beta blockade might precipitate a thyroid storm; therefore, monitor patients for signs of thyrotoxicosis when withdrawing beta-blocking therapy.

adverse reactions

6 ADVERSE REACTIONS Most common adverse reactions (incidence > 10%) are symptomatic hypotension (hyperhidrosis, dizziness) and asymptomatic hypotension ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact American Regent, Inc. at 1-800-734-9236 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience 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 clinical practice. The following adverse reaction rates are based on use of esmolol hydrochloride in clinical trials involving 369 patients with supraventricular tachycardia and over 600 intraoperative and postoperative patients enrolled in clinical trials. Most adverse effects observed in controlled clinical trial settings have been mild and transient. The most important and common adverse effect has been hypotension [see Warnings and Precautions (5.3) ] . Deaths have been reported in post-marketing experience occurring during complex clinical states where esmolol hydrochloride was presumably being used simply to control ventricular rate [see Warnings and Precautions (5.5) ].

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate reliably their frequency or to establish a causal relationship to drug exposure. Cardiac Disorders Cardiac arrest, Coronary arteriospasm Skin and Subcutaneous Tissue Disorders Angioedema, Urticaria, Psoriasis
