Dosage Guidelines & Tips

How to take Adenosine (Adenocard)?

Use Adenosine (Adenocard) exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

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.

Adenosine 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 adenosine.

What should I do if I missed a dose of Adenosine (Adenocard)?

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