Flecainide Acetate is a specialized cardiovascular medication belonging to the Class IC anti-arrhythmic group. It is specifically engineered to stabilize the electrical activity of the heart. It works by blocking the sodium channels in the heart muscle cells, which slows the conduction of electrical impulses. This helps "reset" the heart to a normal rhythm and prevents the heart from beating too fast or irregularly. Because of its potency, Flecainide is typically reserved for patients who do not have structural heart disease (such as a previous heart attack or heart failure).
Product Type: Class IC Anti-arrhythmic
Active Ingredient: Flecainide Acetate (100mg)
Manufacturer: Various (E.g., Tambocor by iNova/Meda / Generic Equivalents)
Pack Size: 60 or 100 Tablets
Route: Oral
Availability: Strictly Prescription Required (POM) — Cardiologist consultation mandatory
Suitable For: Adults with specific heart rhythm disorders
Flecainide is a primary treatment for maintaining a normal sinus rhythm in specific conditions:
Atrial Fibrillation (AFib): Preventing paroxysmal (intermittent) AFib in patients without structural heart disease.
Atrial Flutter: Converting or preventing irregular rapid heart rates in the upper chambers.
PSVT: Managing Paroxysmal Supraventricular Tachycardia.
Ventricular Arrhythmias: Treating life-threatening sustained ventricular tachycardia (only under extreme specialist supervision).
Pro-arrhythmic Risk: Flecainide can occasionally cause new or worsened heart rhythm problems. Structural Heart Disease: It must never be used in patients who have had a heart attack (Myocardial Infarction) or those with Heart Failure, as it increases the risk of sudden cardiac death in these groups. Liver & Kidney Health: Dosing must be strictly adjusted for patients with renal or hepatic impairment to avoid toxic buildup. Electrolyte Balance: Low Potassium or low Magnesium levels make the drug less effective or more dangerous; your doctor will monitor these via blood tests. Pacemaker Alert: Flecainide can increase "pacing thresholds," meaning your pacemaker may need adjustment if you start this medication.
For maximum safety and efficacy, Flecainide must be taken at precise intervals to maintain steady blood levels.
Standard Dosage:
Adults: Typically 50mg to 100mg twice daily (every 12 hours). Your doctor may gradually increase the dose up to a maximum of 300mg per day.
Application Tips:
Consistency: Take the tablet at the same time every day (e.g., 8:00 AM and 8:00 PM) to ensure your heart is always protected.
With or Without Food: It can be taken with or without a meal. However, in children or infants, milk can interfere with absorption—consult your pediatrician if applicable.
Avoid High Caffeine: Excessive caffeine can trigger the very arrhythmias Flecainide is trying to prevent.
Do Not Skip: If you miss a dose, take it as soon as you remember, unless it is almost time for your next dose. Never take a double dose.
Common side effects include dizziness, visual disturbances (blurred vision or difficulty focusing), and nausea. Some patients may experience a "metallic taste" or shortness of breath. If you experience a sudden "thumping" in your chest, fainting, or extreme swelling of the legs, contact your cardiologist or Sanlive Pharmacy immediately.
Store in a cool, dry place below 30°C, protected from light and moisture. Keep the tablets in their original blister packaging until use. Keep out of reach of children.
Q: Why do I need an "ECG" when starting this?
A: Your doctor needs to measure the "intervals" on your heart trace (specifically the QRS and PR intervals). If Flecainide slows your heart's electricity too much, the dose must be lowered.
Q: Can I take it with "Amiodarone" or "Digoxin"?
A: Use extreme caution. Flecainide can significantly increase the levels of Digoxin in your blood. These combinations require very close monitoring by a specialist.
Q: Is it a "Blood Thinner"?
A: No. Flecainide controls the rhythm of the heart. Many AFib patients take a blood thinner (like Xarelto or Eliquis) alongside Flecainide to prevent strokes.
Q: What is the "Pill-in-the-Pocket" approach?
A: Some patients are instructed to take a single large dose of Flecainide only when they feel an episode of AFib starting. This should only be done if explicitly directed and trialed in a hospital by your doctor.
