Brand names: Lexiscan
Lexiscan is an injectable drug used to induce stress for heart imaging in patients unable to undergo an exercise stress test.
Lexiscan may cause fatal cardiac arrest, life-threatening arrhythmias (irregular heartbeat), myocardial infarction (heart muscle obstruction), and first-, second-, or third-degree AV block or sinus bradycardia, and hypotension. Also, talk to your doctor if you have COPD, asthma, or other respiratory conditions.
Lexiscan should not be used in patients with sinus node dysfunction or second- or third-degree AV block (conduction defects) unless they have a pacemaker.
Tell your doctor about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Lexiscan. Also, talk to your doctor about your complete medical history, especially if you have any history of asthma and other respiratory complaints.
