Consumer Medicine Information
What is in this leaflet
This leaflet answers some common questions about Adenosine Mylan.
It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have benefits and risks. Your doctor has weighed the risks of you taking adenosine against the benefits expected for you.
If you have any concerns about taking this medicine, talk to your doctor or pharmacist.
Keep this leaflet with your medicine. You may need to read it again.
What this medicine is used for
Adenosine Mylan 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 can also be used as an aid to doctors to understand how your heart is working.
It works by slowing down the electrical impulses that control heart rhythm. This allows the heart rhythm to return to normal.
Adenosine 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.
