Warnings

Flecainide is used to prevent certain types of life-threatening irregular heartbeats. Flecainide is in a class of medications called antiarrhythmics. It works by slowing electrical signals in the heart to stabilize the heart rhythm.

Flecainide comes as a tablet to take by mouth. It is usually taken once every 12 hours. Some people may take flecainide once every 8 hours if they experience side effects or if their condition cannot be controlled by taking flecainide every 12 hours. Take flecainide at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take flecainide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

You may be hospitalized when you begin your treatment with flecainide. Your doctor will monitor you carefully during this time and for as long as you continue to take flecainide. Your doctor will probably start you on a low dose of flecainide and gradually increase your dose, not more than once every 4 days. Your doctor may also decrease your dose once your condition is controlled.

Flecainide may control your condition, but will not cure it. Continue to take flecainide even if you feel well. Do not stop taking flecainide without talking to your doctor. If you suddenly stop taking flecainide, your condition may become worse.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
