Propafenone ( proe-pa-FEEN-none) belongs to the group of medicines known as antiarrhythmics. It is used to treat abnormal heart rhythms. Propafenone produces its helpful effects by slowing nerve impulses in the heart and making the heart tissue less sensitive. There is a chance that Propafenone may cause new heart rhythm problems or make worse those that already exist. Since similar medicines have been shown to cause severe problems in some patients, Propafenone is only used to treat serious heart rhythm problems. Discuss this possible effect with your doctor. Propafenone is available only with your doctor's prescription, in the following dosage form: Oral Extended-release tablets (U.S.) Tablets (U.S. and Canada)
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. Propafenone comes as a tablet to take by mouth. It usually is taken every 8 hours. Propafenone 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.
