Flecainide is an antiarrhythmic tablet used to steady fast or irregular heart rhythms, sold here as plain Flecainide 100mg and generic Tambocor 50mg and 100mg.
Flecainide
100mg
Flecainide 100mg tablets, a class IC antiarrhythmic used to steady fast or irregular heart rhythms such as atrial fibrillation, atrial flutter and supraventricular tachycardia.
Flecainide is an antiarrhythmic — a medicine that steadies the heartbeat. It is used to prevent and treat certain fast or irregular rhythms, mostly supraventricular ones such as paroxysmal atrial fibrillation (episodes of a fast, irregular beat that start in the upper chambers of the heart) and paroxysmal supraventricular tachycardia (sudden spells of a very fast but regular beat). It is also used for some serious ventricular rhythm disorders, which start in the lower chambers. It does not suit every irregular heartbeat: when the heart muscle is damaged, for example after a heart attack, other treatments are chosen instead.
Each heartbeat is set off by a wave of electrical activity that spreads through the heart muscle, driven by sodium moving through channels in the cell walls. Flecainide partly blocks those channels, so the wave travels more slowly and a rhythm that loops back on itself loses the momentum it needs. The structure of the heart is untouched; what changes is the timing.
Both are immediate-release tablets, swallowed whole with water. Flecainide is the plain version, sold as 100mg tablets. generic Tambocor is the brand-name version of the same medicine and comes as 50mg and 100mg tablets, so it is the one to choose if you need the lower strength. Both sit in the Heart & Blood Pressure range. Most people take a tablet morning and evening, roughly twelve hours apart, and it makes no difference whether that is before or after food — a meal can simply be kinder on the stomach.
Most people who notice anything do so in the first days or after a dose increase: dizziness, blurred vision, headache, nausea or tiredness. Now and then the medicine unsettles the rhythm it was meant to steady, and fainting, a fresh run of very fast beats, chest pain or sudden breathlessness needs urgent treatment. Swollen ankles, or breathlessness on effort that used to be easy, can also mean the heart is struggling.
Other antiarrhythmics, beta-blockers and the calcium-channel blockers verapamil and diltiazem all slow the heart's electrical signals, and flecainide adds to that. Some medicines push flecainide levels up by blocking the liver enzyme that clears it — fluoxetine, paroxetine and quinidine are examples — and a higher level means more chance of side effects. Leave the tablets in their original pack and out of direct sun.
Flecainide can be ordered online with delivery to Hong Kong. The page lists Flecainide tablets in 100mg and generic Tambocor in 50mg and 100mg tablets. If a parcel does not arrive within the delivery window, or arrives damaged, it is sent again free, and if that is not possible the order is refunded.
It depends on the product, strength and pack size. Each of the two flecainide products listed here shows its current prices in HKD or the currency you select.
Yes, generic Tambocor is listed as 50mg and 100mg tablets and contains flecainide. The plain version, Flecainide tablets, is also sold, at 100mg. Both options here are tablets containing flecainide.
Tambocor is a brand name of flecainide. Here, flecainide can be bought online as generic Tambocor and flecainide tablets. These are generics, not the original brand.
Twice a day is the usual pattern, with doses about twelve hours apart, swallowed whole with water. Before or after a meal both work; eating first suits anyone whose stomach feels queasy.
No, they steady the heartbeat in different ways. Beta-blockers blunt the effect of adrenaline on the heart, while flecainide blocks the sodium channels that carry each electrical signal through heart muscle. Taken together they slow conduction more than either does alone.
Dizziness is one of the most commonly reported effects, and it tends to show up in the first days of treatment or after the dose is increased. Blurred vision, headache and nausea are also common. Rising slowly from a chair or bed helps if light-headedness is bothering you.
The fast or irregular beats can come back, because the medicine holds the rhythm steady only while it is being taken. Where possible the dose is stepped down over time rather than stopped in one go.
No. It keeps the rhythm steady, or cuts short an episode, only while it is in the body, and the underlying tendency stays. Some people take it for years, others for a limited stretch, depending on how settled the rhythm becomes.
