Flécaïnide pour les battements de cœur irréguliers

About flecainide

Flecainide is used to treat arythmies. An arrhythmia is an irregularity in your heartbeat, which causes your heart to skip a beat, beat unevenly or beat very fast or very slowly.

Flecainide works by correcting irregular heartbeats to a normal rhythm and by slowing an overactive heart. It will be prescribed for you by a heart specialist doctor. There are two strengths of tablet available (50 mg and 100 mg).

Before taking flecainide

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking flecainide it is important that your doctor knows:

• If you have a pacemaker fitted or if you have any heart problems other than your abnormal heart rhythm. In particular, let your doctor know if you have heart failure, or if you have had a heart attack.

• Si vous avez des problèmes avec le fonctionnement de votre foie, ou des problèmes avec le fonctionnement de vos reins.

• Si vous êtes enceinte ou si vous allaitez.

• Si vous prenez ou utilisez d'autres médicaments. Cela inclut tous les médicaments que vous prenez et qui sont disponibles à l'achat sans ordonnance, ainsi que les médicaments à base de plantes et complémentaires.

• Si vous avez déjà eu une réaction allergique à un médicament.

How to take flecainide

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about flecainide and will provide you with a full list of the side-effects which you may experience from taking it.

• Your doctor will tell you what the right dose of flecainide is for you. The dose may need to be adjusted as your symptoms become controlled, so make sure you take flecainide exactly as your doctor tells you to. Flecainide tablets are usually taken twice each day. Your dose will be printed on the label of the pack to remind you about what the doctor said to you.

• Try to take your doses around the same times of day, as this will help you to remember to take them regularly.

• You can take flecainide tablets either before or after food.

• If you forget to take a dose, leave out the missed dose but make sure that you remember to take your next dose when it is due. Do not take two doses together to make up for a forgotten dose.
  

Tirer le meilleur parti de votre traitement

• Try to keep your regular appointments with your doctor. This is so your doctor can check your heart rhythm and monitor your progress.

• Treatment with flecainide is usually long-term unless you experience an adverse effect. You should continue to take it unless you are advised otherwise by your doctor.

• If you are having an operation or any medical/dental treatment, remember to tell the person carrying out the treatment that you are taking flecainide. This is because it can interfere with some local anaesthetics and increase the risk of side-effects.

• If you buy any medicines 'over the counter', always check with a pharmacist that they are suitable for you to take alongside your other medicines. A medicine called cimetidine (which is taken to reduce stomach acid) can interfere with flecainide.

Can flecainide cause problems?

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with flecainide. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

If you experience any other symptoms which you think may be due to flecainide, speak with your doctor or pharmacist for further advice.
