Flecainide Acetate is a specialized cardiac medication that belongs to the Class IC anti-arrhythmic category. It works by blocking the fast sodium channels in the heart's muscle cells (myocytes). By slowing the conduction of electrical impulses throughout the heart, Flecainide stabilizes the heart's rhythm and prevents the "short-circuiting" that leads to rapid or irregular heartbeats. It is particularly effective at maintaining a normal sinus rhythm in patients with overactive electrical pathways in the upper chambers (atria) or specific pathways that cause sudden racing of the heart.
In Nigeria, Flecainide 50mg (commonly known as Tambocor) is a premier clinical choice for managing complex arrhythmias. It is available through registered specialist pharmacies like Sanlive Pharmacy to ensure patients receive authentic, high-stability tablets manufactured under strict international standards and stored in a cool, dry environment to maintain the chemical integrity of the 50mg dose.
Important: This is a specialized, prescription-only medication. The "Structural" Rule: Flecainide must only be used in patients with a "structurally normal" heart; it is strictly contraindicated if you have had a heart attack (myocardial infarction), heart failure, or left ventricular dysfunction. The "Start-up" Warning: For certain conditions, the first few doses are often given in a hospital setting where your heart rhythm (ECG) can be monitored. Do not use if you have a "Permanent" Atrial Fibrillation or a pre-existing second or third-degree heart block without a pacemaker.
Flecainide Acetate 50mg Tablets are primarily used to:
Prevent and treat Paroxysmal Atrial Fibrillation (AFib) and Atrial Flutter
Manage Paroxysmal Supraventricular Tachycardia (PSVT), including Wolff-Parkinson-White (WPW) syndrome
Prevent life-threatening Ventricular Tachycardias in specific, non-structural cases
Maintain a "Normal Sinus Rhythm" after a successful cardioversion (electrical shock to the heart)
Reduce the frequency of symptomatic "palpitations" and racing heart episodes
Stabilize the heart's electrical system in patients with "Flecainide-sensitive" arrhythmias
This product is suitable for:
Adults with disabling heart rhythm disorders who have no history of heart muscle damage
Patients whose arrhythmias have not responded to simpler medications like Beta-blockers
Individuals requiring a potent "rhythm-control" strategy for paroxysmal AFib
Not recommended for: Patients with a history of heart attack or "congestive heart failure." It is strictly contraindicated for individuals with severe liver or kidney disease without intensive dose adjustment. Use with extreme caution in elderly patients, as they are more prone to "pro-arrhythmia" (the medicine causing a new rhythm problem). Consult our pharmacist if you are taking Digoxin or Amiodarone, as Flecainide can significantly interact with these drugs.
Take exactly as prescribed; the standard starting dose is usually 50mg to 100mg twice daily
Consistency is Vital: Take your doses at the same time every day (e.g., 8 AM and 8 PM) to keep heart levels steady
Swallow the tablet whole with a glass of water; it can be taken with or without food
The "Milk" Rule (for Children): If prescribed for a child, be aware that high milk intake can reduce the absorption of Flecainide; keep milk intake consistent
If a dose is missed, take it as soon as you remember, but skip it if it is within 4 hours of your next dose—never take a double dose
Regular ECG (heart trace) and blood tests for kidney/liver function are mandatory to monitor for "QRS widening" or toxicity
Flecainide is effective, but some individuals may experience:
Dizziness or lightheadedness (very common)
Visual disturbances (blurred vision or "seeing spots")
Nausea or a metallic taste in the mouth
Headache or tiredness
Rare but serious: "Pro-arrhythmia" (feeling like your heart is racing in a new or different way)
Rare: Shortness of breath or swelling of the ankles
Rare: Tremors or "shakiness"
Seek immediate medical attention if you experience a fainting spell, sudden severe shortness of breath, or if you feel a new, rapid heart rhythm that does not stop.

Can I take this for my high blood pressure?
No. Flecainide is strictly for heart rhythm (the "timing" of the beat), not for blood pressure. However, many people take blood pressure medicine alongside Flecainide to keep their heart healthy.
What is a "pill-in-the-pocket" strategy?
Some doctors prescribe Flecainide to be taken only "as needed" when you feel a racing heart episode start. You must only do this if your cardiologist has specifically told you it is safe for your type of heart rhythm.
Is it safe to exercise while taking Flecainide?
In many cases, yes. However, intense exercise can sometimes change how the medicine works on the heart. You should discuss your exercise routine with your cardiologist before starting a new gym program.
Where can I purchase Flecainide 50mg Tablets in Nigeria?
