Flecainide 100mg

What Is Flecainide 100mg

Flecainide 100mg is a prescription heart rhythm medicine used to treat certain types of irregular heartbeat (arrhythmia).

An arrhythmia means the heart does not beat in a normal pattern. It may beat too fast, too slow, or unevenly.

When the heart rhythm is not regular, it can affect blood flow and may cause dizziness, weakness, chest discomfort, or shortness of breath.

Doctors prescribe Flecainide 100mg tablets to help restore and maintain a normal heartbeat.

This medicine is usually used in specific heart rhythm disorders and is not used for simple high blood pressure.

It belongs to a group called antiarrhythmic medicines, which help control abnormal electrical activity in the heart.

Cardiologists (heart specialists) carefully prescribe Flecainide tablets after checking heart condition through tests like ECG.

What This Medicine Does in the Body

Flecainide 100mg works by controlling the electrical signals in the heart.

The heart beats because of small electrical impulses that travel through heart muscles.

In arrhythmia, these signals become too fast or irregular.

Flecainide tablets slow down these abnormal electrical signals and help restore a steady rhythm.

This helps the heart beat in a more regular and controlled way.

As the rhythm becomes stable, blood flows more efficiently to the body.

Doctors prescribe Flecainide 100mg tablets because a stable heartbeat reduces symptoms like palpitations, dizziness, and fatigue.

Palpitations mean feeling like the heart is racing, fluttering, or skipping beats.

Uses of Flecainide 100mg / Flecainide 100mg Used For

Doctors mainly prescribe Flecainide 100mg for arrhythmias (irregular heartbeats).

One common use is atrial fibrillation, a condition where the upper chambers of the heart beat irregularly.

This may cause fast heartbeat, tiredness, and shortness of breath.

Doctors also use Flecainide tablets for supraventricular tachycardia (SVT).

SVT is a condition where the heart suddenly beats very fast due to abnormal electrical signals.

In some cases, Flecainide 100mg tablets are used to prevent repeated episodes of irregular heartbeat.

Doctors may also prescribe it for long-term rhythm control in selected patients after careful heart evaluation.

Patients usually undergo ECG monitoring before and during treatment to ensure safety.

How Flecainide 100mg Work

Flecainide 100mg works by slowing down electrical signals in the heart.

It blocks specific sodium channels in heart cells.

These channels control how electrical impulses move through the heart.

When these channels are blocked, abnormal signals slow down or stop.

Flecainide tablets help the heart return to a normal and steady rhythm.

This reduces sudden fast heartbeats and improves heart function.

Doctors prescribe Flecainide 100mg tablets only when needed because heart rhythm medicines require careful dose control.

Regular monitoring is important during treatment to avoid rhythm changes.

Patients should take the medicine exactly as prescribed and not skip doses.

Side Effects of Flecainide 100mg

Like all medicines, Flecainide 100mg may cause side effects in some patients. Some are mild, while others may need medical attention.

Common side effects include dizziness, blurred vision, headache, nausea, and tiredness.

Some patients may feel mild palpitations or weakness during early treatment.

Rare but serious side effects may include worsening irregular heartbeat, chest pain, fainting, or shortness of breath.

These may indicate heart rhythm changes that need urgent medical care.

Patients with heart disease, kidney problems, or structural heart issues should inform their doctor before using Flecainide tablets.

Doctors may regularly check ECG and heart function during treatment.

Alcohol should be avoided because it may increase dizziness and heart rhythm instability.
