IMPORTANT WARNING:     

Why is this medication prescribed?     

Propafenone is used to treat arrhythmias and to maintain a normal heart rate. It acts on the heart muscle to improve the heart's rhythm.

How should this medicine be used?     

Propafenone comes as a tablet to take by mouth. It usually is taken every 8 hours. This medication is sometimes started in the hospital where your response can be monitored. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take propafenone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Propafenone controls irregular heartbeats, but does not cure them. Continue to take propafenone even if you feel well. Do not stop taking propafenone without talking to your doctor. Your heartbeat may become irregular if you suddenly stop taking propafenone.
