Flecajol 50 Tablet is a prescription medicine used to fix certain serious heartbeat problems like atrial fibrillation, supraventricular tachycardia (SVT), and some types of dangerous irregular rhythms from the lower part of the heart. Its main ingredient is Flecainide, works by slowing down the faulty electrical signals in your heart so it can beat more normally.

It’s taken by mouth in tablet form and should only be used when your doctor advises, because it can have serious side effects if not taken correctly. It’s not suitable for people who’ve had a recent heart attack or have severe heart failure.

Doctors may give you Flecajol 50 Tablet for:

• Atrial fibrillation or flutter – fast, uneven heartbeats from the top chambers of your heart.

• Supraventricular tachycardia (SVT) – sudden spells of very fast heartbeat starting above the ventricles.

• Ventricular arrhythmias – dangerous rhythm problems starting in the lower chambers.

This medicine helps your heart pump better and can reduce symptoms like dizziness, shortness of breath, or chest discomfort caused by irregular rhythms.

Your heart has its own “electrical wiring” to keep the beats steady. In arrhythmia, these signals can get too fast, too slow, or mixed up. Flecajol blocks certain sodium channels in the heart muscle, which calms down those overactive signals.

Think of it like fixing a flickering tube light—it evens out the flow so everything runs smoothly again.

Flecajol 50 Tablet may react with:

• Other heart rhythm medicines
