What is Rythmol (propafenone)?

Rythmol belongs to the category of drugs called Class IC antiarrhythmic. In certain situations, Rythmol can be used to prevent serious heart rhythm disorders such as atrial fibrillation and paroxysmal supraventricular tachycardia. Rythmol can reduce the risk of blood clots, heart attacks, and stroke by blocking signals in the heart that cause an unsteady heartbeat.

Consult the package instructions before taking Rythmol.
Always follow your doctor’s directions.

  • Rythmol may be taken with or without food.
  • Rythmol is taken orally. The dosage will depend on each individual.
  • Take this medication at the same time each day, typically every 8 hours.


Make sure to tell your doctor:

  • If you have a breathing disorder
  • If you have liver or kidney disease
  • If you have lupus, myasthenia gravis, or an abnormal Antinuclear Antibody Test
  • If you use a pacemaker or defibrillator
  • If you are pregnant or breastfeeding

You should not take Rythmol if:

  • You have heart failure or have recently had a heart attack
  • You have Brugada syndrome
  • You have sick sinus syndrome
  • You have severe low blood pressure or a history of fainting
  • You have an uncontrolled electrolyte balance
  • You are concerned about your ability to have children. Rythmol may affect fertility in men.

Side Effects of Rythmol

Common side effects of Rythmol:

  • Irregular heartbeat
  • Nausea
  • Vomiting
  • Constipation
  • Headache
  • Dizziness
  • Fatigue
  • Unpleasant taste in the mouth

Seek medical attention if you experience any severe side effects like:

  • Shortness of breath
  • Sudden weight gain
  • Fever, chills, or a sore throat
  • Fast and pounding heartbeats
  • Fluttering in your chest
  • Swelling in the limbs


What drugs interact with Rythmol?

Many over-the-counter medicines, herbal products, and vitamins can affect Rythmol. Medicines for infections, asthma, heart problems, high blood pressure, depression, cancer, malaria, or HIV can cause complications with Rythmol. Always inform your doctor of all the medications you are taking.

How long does it take for Rythmol to work?

A single oral dose of Rythmol will have a relatively quick effect within 2 to 3 hours. When you just start treatment with Rythmol, you may be more prone to infections because propafenone can lower your white blood cell count. Within two weeks, white blood cell levels should return to normal.
