Flecainide

What is Flecainide?

Flecainide is a prescription anti-arrhythmic medicine used to treat certain types of serious irregular heartbeats. Doctors often prescribe it to stabilize the heart rhythm in conditions like atrial fibrillation, atrial flutter, and certain ventricular arrhythmias. The medicine works by helping the heart beat more regularly, reducing episodes of palpitations, chest discomfort, and dizziness. Antiarrhythmic tablets are usually part of a long-term treatment plan and must be taken exactly as instructed by your healthcare provider.

Flecainide Used For

Flecainide tablets are used to manage and prevent abnormal heart rhythms such as:

• Atrial fibrillation (AFib)

• Atrial flutter

• Paroxysmal supraventricular tachycardia (PSVT)

• Certain life-threatening ventricular arrhythmias

It helps restore a steady heartbeat, reduce symptoms, and prevent dangerous rhythm disturbances.

Chemical Composition

The active ingredient is Flecainide Acetate, a Class IC anti-arrhythmic agent. The tablet also contains inactive compounds that support stability, absorption, and consistent release of the medication.

Flecainide Mechanism

Flecainide works by blocking sodium channels in the heart. By slowing electrical signals, it prevents fast or irregular heartbeats. This helps maintain a normal rhythm, allowing the heart to pump blood more effectively.

How It Helps Improve Heart Rhythm

People with arrhythmias often experience sudden fast heartbeats, fluttering, and dizziness. Flecainide stabilizes electrical activity in the heart so these episodes occur less often. With regular use, it reduces the frequency and severity of rhythm problems, helping patients remain active and comfortable.

What Are the Other Benefits?

• Helps maintain long-term heart rhythm stability

• Reduces risk of sudden arrhythmia episodes

• Improves exercise tolerance

• Lessens palpitations and fatigue

• Available in easy-to-take oral tablets
