Adenosine (60mg)

Adenosine (60mg) — Uses and Benefits

Adenosine is used to treat episodes of fast, abnormal heart rhythms, particularly a condition called paroxysmal supraventricular tachycardia (PSVT).

WHAT THIS MEDICINE IS USED FOR

• To quickly convert certain fast abnormal heart rhythms (PSVT) back to a normal rhythm
• Used in emergency and hospital settings under continuous ECG monitoring
• Sometimes used during cardiac stress testing to help evaluate blood flow to the heart

HOW IT WORKS

• Slows down electrical signals passing through a part of the heart called the AV node
• This brief pause interrupts the abnormal electrical circuit causing the fast heartbeat
• Allows the heart's natural pacemaker to take over and restore a normal rhythm
• Its effect is very short-lived, lasting only a few seconds

WHAT IT IS NOT USED FOR

• Not used for routine, long-term control of heart rhythm problems
• Not effective for irregular rhythms like atrial fibrillation or ventricular tachycardia
• Not a treatment for chest pain unrelated to heart rhythm testing
• Not for use outside a hospital or monitored clinical setting
