Flecainide Acetate



What is Flecainide Acetate generic?

What is Flecainide Acetate generic? Tambocor Flecainide is used to treat certain types of serious (possibly fatal) irregular heartbeat (such as persistent ventricular tachycardia and paroxysmal supraventricular tachycardia). Tambocor heart medication is used to restore normal heart rhythm and maintain a regular, steady heartbeat. It is also used to prevent certain types of irregular heartbeat from returning (such as atrial fibrillation). Moreover, Flecainide is known as an anti-arrhythmic drug. Tambocor and alcohol work by blocking certain electrical signals in the heart that can cause an irregular heartbeat. Treating an irregular heartbeat can decrease the risk for blood clots, and this effect can reduce your risk of heart attack or stroke.

Older adults should discuss the risks and benefits of Tambocor and alcohol with their doctor or pharmacist, as well as other effective and possibly safer treatments.
