## What is Adenocard?

Adenocard is a naturally occurring substance that relaxes and dilates blood vessels. This medicine also affects the electrical activity of the heart.

Adenocard is used to help restore normal heartbeats in people with certain heart rhythm disorders.

Adenocard is also used during a stress test of the heart.

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

## Warnings

Before receiving Adenocard, 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 Adenocard 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 Adenocard.

Tell your doctor if you have ever had:

## How is Adenocard 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.

Adenocard 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 Adenocard.
