Digoxin and verapamil are sometimes used together with Adenosine (Adecard). In rare cases, this combination may be linked to ventricular fibrillation. This is a dangerous heart rhythm problem in which the lower chambers of the heart quiver instead of pumping blood properly. Tell your doctor about all the heart medicines you take, including digoxin and verapamil, before you get Adenosine.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
