"An increasing number of emergency department patients are being given computed tomography (CT) scans â€” even those patients who are unlikely to benefit and are most likely to experience harm from the scan.
"Beyond the risk posed by ion"...
Advise patients that they may be at increased risk of fatal and nonfatal heart attacks, abnormal heart rhythms, cardiac arrest, significant increase or decrease in blood pressure, hypersensitivity reactions, seizures, bronchoconstriction, or cerebrovascular accidents (stroke) with the use of Lexiscan [see WARNINGS AND PRECAUTIONS].
Patients should be instructed to avoid consumption of any products containing methylxanthines, including caffeinated coffee, tea or other caffeinated beverages, caffeine-containing drug products, aminophylline and theophylline for at least 12 hours before a scheduled radionuclide MPI. Question patients about a history of seizures.
Prior to Lexiscan administration, patients should be informed of the most common reactions (such as shortness of breath, headache and flushing) that have been reported in association with Lexiscan during MPI.
Patients with COPD or asthma should be informed to discuss their respiratory history and administration of pre-and post-study bronchodilator therapy with their clinician before scheduling an MPI study with Lexiscan.
