Flecainide

Flecainide is an anti-arrhythmic medicine used to treat and prevent serious irregular heart rhythms, particularly in conditions like atrial fibrillation and ventricular arrhythmias. It works by stabilizing the heart's electrical activity, helping the heart beat more regularly. Flecainide is usually prescribed when other treatments have not been effective. It is available in tablet form and should be taken strictly under medical supervision due to potential side effects and interactions with other medications.

Uses of Flecainide

• Treatment of atrial fibrillation (irregular heartbeat)
• Prevention of paroxysmal supraventricular tachycardia (PSVT)
• Management of ventricular tachycardia (fast heart rate from the lower chambers)
• Used in certain genetic heart rhythm conditions like Brugada syndrome (under specialist care)

How Flecainide Works

Flecainide works by blocking sodium channels in the heart, which helps slow down electrical signals. This stabilizes the heart rhythm and prevents abnormal electrical activity that leads to arrhythmias. It allows the heart to pump blood more efficiently by maintaining a regular heartbeat.

Benefits of Flecainide

• Helps maintain a normal and steady heartbeat
• Reduces the risk of stroke related to atrial fibrillation
• Improves quality of life by reducing palpitations and fatigue
• Effective in preventing recurrence of heart rhythm disorders

How to Take Flecainide

Flecainide should be taken exactly as prescribed by your doctor. It is usually taken orally with or without food. The dosage depends on your medical condition and response to treatment. Do not stop taking it abruptly without consulting your doctor. Regular monitoring of heart function is required while using Flecainide.

Type of Dosage Available

• Oral Tablets
• Oral Solution (in some regions)

Side Effects of Flecainide

• Dizziness or lightheadedness
• Blurred vision
• Nausea
• Shortness of breath
• Palpitations or worsening arrhythmias
• Chest pain (seek immediate medical attention)

Safety Advice

• Not recommended in patients with structural heart disease
• Regular ECG monitoring is required

• Use cautiously in elderly patients
• Pregnant or breastfeeding women should consult a doctor before use

Q: What is Flecainide used for?
A: Flecainide is used to treat irregular heartbeats like atrial fibrillation and certain types of ventricular tachycardia.

Q: How long does Flecainide take to work?
A: Flecainide usually starts working within a few hours, but it may take days to see the full effect on heart rhythm.

Q: Can Flecainide cause side effects?
A: Yes, it may cause dizziness, vision changes, or palpitations. Seek medical attention if side effects worsen.
