This leaflet provides important information about using ADENOSINE VIATRIS. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using ADENOSINE VIATRIS.

Where to find information in this leaflet:

1. Why am I using ADENOSINE VIATRIS?

ADENOSINE VIATRIS contains the active ingredient adenosine.

ADENOSINE VIATRIS is used to treat a condition called paroxysmal supraventricular tachycardia (including a condition called Wolff-Parkinson-White syndrome). This is when the heart beats too rapidly. If left untreated, this condition can be life threatening.

ADENOSINE VIATRIS is also used as an aid to doctors to understand how your heart is working.

ADENOSINE VIATRIS works by slowing down the electrical impulses that control heart rhythm. This allows the heart rhythm to return to normal.

ADENOSINE VIATRIS is only given in hospitals. It is given to you as an injection. The effect of this medicine only lasts for a couple of minutes.

Ask your doctor if you have any questions about why this medicine has been prescribed for you.

Your doctor may have prescribed it for another use.

There is no evidence this medicine is addictive.

This medicine is available only with a doctor's prescription.
