What is Lexiscan?
Lexiscan (regadenoson) is a stress agent that works by increasing blood flow in the arteries of the heart.
Lexiscan is given in preparation for a radiologic (x-ray) examination of blood flow through the heart to test for coronary artery disease.
Lexiscan may also be used for purposes not listed in this medication guide.
You should not use Lexiscan if you have a serious heart condition such as AV block or "sick sinus syndrome" (unless you have a pacemaker).
Tell your caregivers if you have a serious side effect such as chest pain or heavy feeling, pain spreading to the jaw or shoulder, sweating, general ill feeling, wheezing or trouble breathing, slow heart rate, severe headache, seizure (convulsions), weak pulse, slow breathing, or fainting.
