Cardiolite (prep kit for technetium tc99 sestamibi for injection) is a myocardial perfusion agent used to detect coronary artery disease by localizing myocardial ischemia (reversible defects) and infarction (non-reversible defects), in evaluating myocardial function and developing information for use in patient management decisions. Cardiolite is available in generic form. Common side effects of Cardiolite include headache, changes is taste or smell, abdominal discomfort, nausea, and cardiovascular effects (chest pain, angina). Rare side effects of Cardiolite include temporary joint pain, dizziness, irregular heart beat, lightheadedness or fainting, vomiting, allergic reactions (shortness of breath, low blood pressure, low heart rate, weakness), flushing, swelling, injection site inflammation, dry mouth, fever, itching, rash, and hives.

For myocardial imaging the suggested dose range for I.V. administration of Cardiolite in a single dose to be employed in the average patient (70 Kg) is 370-1110 MBq (10-30 mCi). Cardiolite may interact with other drugs. Tell your doctor all medications and supplements you use. During pregnancy, Cardiolite should be used only if prescribed.
