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
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.
