What is Cardiolite

What Cardiolite is used for

Your doctor may have prescribed Cardiolite for another purpose. Ask your doctor if you have any questions about why Cardiolite has been prescribed for you. If you have any concerns, you should discuss these with your doctor.
This medicine is only available with a doctor’s prescription.

Before you are given Cardiolite your doctor will explain to you the procedure you are about to undergo, and the radioactive medicine you will be given. You must discuss any concerns you have with your doctor.
Cardiolite is not recommended for patients less than 18 years of age. If your doctor believes it is necessary to give Cardiolite to a patient under 18, he or she will discuss the benefits and risks with you.
You must tell your doctor if you have allergies to:
