What is regadenoson?
Regadenoson is a stress agent that works by increasing blood flow in the arteries of the heart.
Regadenoson may also be used for purposes not listed in this medication guide.
You should not receive regadenoson if you have a serious heart condition such as AV block or "sick sinus syndrome" (unless you have a pacemaker).
Before taking this medicine
You should not use this medication if you are allergic to regadenoson, or if you have a serious heart condition such as AV block or "sick sinus syndrome" (unless you have a pacemaker).
To make sure regadenoson is safe for you, tell your doctor if you have ever had:
chest pain or heart problems;
heart disease or high blood pressure;
It is not known whether regadenoson will harm an unborn baby. Tell your doctor if you are pregnant.
It is not known whether regadenoson passes into breast milk or if it could harm a nursing baby. Do not breast-feed within 10 hours after receiving regadenoson. If you use a breast pump during this time, throw out any milk you collect. Do not feed it to your baby.
How is regadenoson given?
Regadenoson is injected into a vein through an IV. A healthcare provider will give you this injection.
After regadenoson is injected, you will be given other intravenous (IV) medications that allow blood vessels to be seen more clearly on the radiologic examination.
Your breathing, blood pressure, oxygen levels, and other vital signs will be watched closely during your stress test.
What happens if I miss a dose?
Since regadenoson is given by a healthcare professional in preparation for medical testing, you are not likely to be on a dosing schedule.
What happens if I overdose?
Since this medication is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.
What should I avoid while receiving regadenoson?
Avoid drinking coffee or other beverages with caffeine for at least 12 hours before your stress test.
