Though this medication often gives great benefits to people with irregular heartbeat, it may rarely cause a serious new irregular heartbeat. Talk with your doctor about the benefits and risks of taking this medication.
This medication is used to help prevent certain types of serious (possibly fatal) irregular heartbeat (such as paroxysmal supraventricular tachycardia and atrial fibrillation). It is used to help maintain a regular, steady heartbeat. Propafenone is known as an anti-arrhythmic drug. It works by blocking the activity of certain electrical signals in the heart that can cause an irregular heartbeat. Treating an irregular heartbeat can decrease the risk for blood clots, and this effect can reduce your risk of heart attack or stroke.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day.
Avoid eating grapefruit or drinking grapefruit juice while using this medication unless your doctor or pharmacist says you may do so safely. Grapefruit can increase the chance of side effects with this medicine. Ask your doctor or pharmacist for more details.
Tell your doctor if your condition does not improve or if it worsens.
