IMPORTANT WARNING:

In a study of people who had experienced heart attacks within the past 2 years, people who took flecainide were more likely to have another heart attack or to die than people who did not take flecainide. There is not enough information to tell whether taking flecainide also increases the risk of heart attack or death in people who have not had heart attacks within the past 2 years. Because of this serious risk and because flecainide has not been shown to help people with irregular heartbeats to live longer, flecainide should be used only to treat people with life-threatening irregular heartbeats.

Tell you doctor if you have atrial fibrillation or atrial flutter (conditions in which the upper chambers of the heart do not beat effectively). People with atrial fibrillation or atrial flutter who take flecainide may have a higher risk of developing certain types of irregular heartbeats.

Talk to your doctor about the risks of taking flecainide.

WHY is this medicine prescribed?

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.

HOW should this medicine be used?

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.

Are there OTHER USES for this medicine?

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

  • tell your doctor if you have heart block (condition in which electrical signals are not passed normally from the upper chambers of the heart to the lower chambers). Your doctor may tell you not to take flecainide.
  • tell your doctor if you have a pacemaker (device that is surgically placed under the skin to control irregular heartbeats) and if you have or have ever had a heart attack, heart failure, or any type of heart disease; low or high levels of potassium in the blood; or liver or kidney disease. Also tell your doctor if you follow a strict vegetarian diet.
