Adenoscan may also be used for purposes not listed in this medication guide.

Important Information

Before receiving Adenoscan, tell your doctor if you have asthma or other breathing problems, or if you have ever had a seizure.

Before taking this medicine

You should not be treated with Adenoscan if you have a serious heart condition such as "sick sinus syndrome" or "AV block" (unless you have a pacemaker), or slow heartbeats that have caused you to faint.

Your doctor will perform tests to make sure you do not have conditions that would prevent you from safely receiving Adenoscan.

Tell your doctor if you have ever had:

It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant.

How is Adenoscan given?

Before your heart stress test: Avoid coffee, tea, cola, chocolate, energy drinks or other sources of caffeine. They can interfere with the results of your test.

Adenoscan is given as an infusion into a vein. A healthcare provider will give you this injection.

You may receive only one dose of this medicine. Repeat doses may be given if needed to restore normal heartbeats.

Your breathing, blood pressure, oxygen levels, and other vital signs will be watched closely.

Your heart rate will be constantly monitored using an electrocardiograph or ECG (sometimes called an EKG). This will help your doctor determine how long to treat you with Adenoscan.

What happens if I miss a dose?

Adenoscan is usually given as a single dose in a medical setting and does not have a daily dosing schedule.

What happens if I overdose?

Since Adenoscan is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.
