Propafenone
About Propafenone
Propafenone is a prescription medicine used to treat and prevent certain types of serious, irregular heartbeats, such as atrial fibrillation and supraventricular tachycardia. It helps restore a normal, steady heart rhythm in individuals whose hearts beat too fast or unevenly. By keeping the heart's rhythm stable, this medication prevents the discomfort and risks associated with sudden heart rhythm changes.
To get the best results, you must take Propafenone consistently at the exact times prescribed by your doctor. You can take this medicine with or without food, but it is important to choose one way and stick to it with every dose to keep your medicine levels stable. Incorporating heart-healthy habits, such as reducing sodium intake and managing stress, can also support your overall heart function while on this treatment.
While taking Propafenone, you may experience mild side effects like a metallic taste in your mouth, dizziness, or mild nausea. However, if you notice serious symptoms such as sudden shortness of breath, a rapid swelling of your ankles or feet, or severe chest pain, you must contact your doctor immediately.
Talk to your doctor before taking Propafenone if you have liver or kidney problems, asthma or other severe obstructive breathing conditions, or a history of abnormal heart rhythms. Propafenone is generally avoided in people with severe heart failure, certain heart block conditions without a working pacemaker, Brugada syndrome, marked disturbances in the body's salts and minerals, or significant breathing obstruction. Your doctor will assess whether this medicine is safe for you before treatment begins.
This medicine can interact with other heart drugs, blood thinners, alcohol, and grapefruit juice, which can dangerously alter how the medication works in your body. If you are pregnant, planning to become pregnant, breastfeeding, or are an older adult, consult your doctor to discuss if this treatment is safe for you.

View AllDrug Warnings
- Monitor Your Heart Rate: Check your pulse as advised by your doctor and report an unusually slow, fast, or irregular heartbeat, fainting, or significant dizziness. Follow the specific heart-rate threshold provided by your healthcare professional.
- Know Your Formulation: Check whether you have been prescribed immediate-release tablets or extended-release capsules, as they have different dosing intervals. Do not switch between formulations or alter extended-release capsules unless your doctor or pharmacist advises you to do so.
- Do Not Stop Treatment on Your Own: Continue taking Propafenone as prescribed. Stopping it without medical advice may allow abnormal heart rhythms to return or worsen.
- Use Caution While Driving: Avoid driving or operating machinery if you experience dizziness, blurred vision, or reduced alertness.
- Attend Regular Heart Check-Ups: Keep all scheduled ECGs, including checks before treatment and periodically during therapy. Propafenone can alter the heart's electrical conduction, including widening the QRS complex, which means the electrical signal takes longer to travel through the heart's lower chambers. Your doctor may use these changes to assess whether your dose remains safe and appropriate.
- Inform Healthcare Providers: Tell your doctor, dentist, surgeon, or emergency healthcare professional that you are taking Propafenone before procedures or new treatments.
- Carry Medical Identification: Consider carrying a medication card or wearing a medical alert bracelet, particularly if you have a significant heart rhythm disorder.
Drug Interactions
The following medicines may interact with Propafenone and require closer monitoring or dose adjustments:
- Other Heart Medicines: Beta-blockers and digoxin may increase the risk of an excessively slow heart rate or other conduction problems. Propafenone may also increase digoxin levels in the blood.
- Medicines That Increase Propafenone Levels: Certain medicines, including ritonavir, ketoconazole, and quinidine, may slow the breakdown of Propafenone and increase the risk of side effects or abnormal heart rhythms.
- Warfarin: Propafenone may increase the effect of warfarin, which can raise the risk of bleeding and may require closer blood-clotting monitoring.

Patients Concern
Disease/Condition Glossary
Arrhythmias: Arrhythmias (irregular heartbeat) is a condition in which your heart beats abnormally, too fast, or too slow. Symptoms of irregular heartbeat include chest pain, shortness of breath, and fast or slow heartbeat. 60 to 100 beats per minute is generally considered a normal heart rate. Pulse indicates your heart rate or the number of times your heart beats in a minute. Normally, the pulse rate increases when you exercise and is slower when you are at rest. Tachycardia means when the heart beats faster than normal, and bradycardia is when the heart beats too slowly. Atrial fibrillation is the most common type of arrhythmia, which causes an irregular and fast heartbeat. Your doctor may run certain tests to diagnose if you have an arrhythmia. Treatment to restore a normal heart rhythm may include medicines like Propafenone, an implantable cardioverter-defibrillator (ICD), a pacemaker, or surgery.
FAQs
Propafenone is used to treat irregular heartbeats. It helps slow down the heart rate and prevent arrhythmias (abnormal heart rhythms). It is prescribed for patients with ventricular arrhythmias, paroxysmal supraventricular tachycardia, atrial fibrillation, or flutter.
Propafenone contains propafenone, i.e. anti-arrhythmic agents that help increase the heart's output force and reduce the rate of heart contractions. Propafenone works on the heart muscle directly and increases the force with which the heart muscle contracts with each heartbeat. Therefore, it makes the heart efficient in pumping blood around the body and slows the heartbeat rate.
Yes, Propafenone may cause yellow or blurred vision in some people. Therefore, be cautious before driving or using machinery.
No, you are not recommended to take amiodarone with Propafenone as co-administration of these two medicines may increase the levels of Propafenone in the blood resulting in Propafenone toxicity. However, please consult a doctor before taking other medicines with Propafenone to adjust the dose appropriately.
You are recommended to avoid taking Propafenone if you have severe heart problems. You had a heart attack within the last 3 months if you suffer from breathing problems (COPD); you suffer from a heart rhythm disorder called Brugada syndrome, myasthenia gravis, or hypotension.
Yes, Propafenone may cause diarrhoea as a side effect. However, it is not happening to everyone. You are recommended to drink plenty of fluids to avoid dehydration. Signs of dehydration include decreased urination or dark, strong-smelling urine. Also, do not take any other medicines to treat diarrhoea without consulting your doctor. If the condition persists or worsens, please consult your doctor.
No, Propafenone is not beta blocker, blood thinner, narcotic or statin. But it is a generic drug.
