Rythmol contains the active ingredient propafenone. It is a prescription antiarrhythmic medication used to help prevent or control certain abnormal heart rhythms.

Paroxysmal Atrial Fibrillation

Rythmol may be used to help manage paroxysmal atrial fibrillation, which is a type of irregular heart rhythm that starts suddenly and may stop on its own.

Atrial fibrillation causes the upper chambers of the heart to beat irregularly and often too quickly. This can lead to symptoms such as:

  • Palpitations
  • Shortness of breath
  • Dizziness
  • Fatigue
  • Chest discomfort

Rythmol may help maintain a normal heart rhythm and reduce the frequency of atrial fibrillation episodes in selected patients.

Atrial Flutter

Rythmol may also be used to help manage certain cases of atrial flutter.

Atrial flutter is another abnormal rhythm that begins in the upper chambers of the heart. It causes the atria to beat very quickly in a more organized pattern than atrial fibrillation.

Rythmol may be used to help restore or maintain a more normal rhythm when a healthcare provider determines that it is appropriate.

Ventricular Arrhythmias

Rythmol may also be used to treat certain serious or life-threatening ventricular arrhythmias.

These abnormal rhythms begin in the lower chambers of the heart and can interfere with the heart’s ability to pump blood effectively.

Because antiarrhythmic medications can sometimes cause new or worsening rhythm problems, Rythmol is generally reserved for patients in whom the expected benefits outweigh the risks.

How Rythmol Works

Rythmol belongs to a class of medications called Class IC antiarrhythmics.

It works mainly by blocking sodium channels in heart muscle cells. This slows the movement of electrical signals through the heart and reduces abnormal electrical activity.

By slowing and stabilizing electrical conduction, Rythmol can help the heart maintain a more regular rhythm.

Effect on the Heart’s Electrical System

The heart depends on precisely timed electrical signals to keep each heartbeat coordinated.

When these signals become abnormal, the heart may beat too fast, too slowly, or irregularly.

Rythmol helps stabilize these electrical signals, but it can also slow conduction too much or trigger another abnormal rhythm in some patients. For this reason, careful medical supervision is important.

Role in Arrhythmia Treatment

Rythmol is not appropriate for every type of abnormal heart rhythm.

A healthcare provider may consider factors such as:

  • The type of arrhythmia
  • Heart structure and function
  • Previous heart attack or heart disease
  • Other medications being taken
  • Kidney and liver function
  • Previous response to antiarrhythmic treatment

Patients may need an electrocardiogram (ECG) and other heart monitoring before and during treatment.

Long-Term Treatment

Some patients may take Rythmol for an extended period to help prevent recurring arrhythmias.

The dose and treatment duration depend on the type of rhythm problem, response to therapy, side effects, and heart monitoring results.

Do not stop Rythmol or change your dose without speaking with your healthcare provider.

Rythmol tablets are taken by mouth, usually every 8 hours, as directed by your healthcare provider.

The dose is based on the type of heart rhythm problem, your response to treatment, side effects, liver function, and heart monitoring results.

Take Rythmol at about the same times each day to help keep a consistent amount of medication in your body.

Starting Dose

The usual starting dose of regular Rythmol tablets is 150 mg every 8 hours, for a total of 450 mg per day.

Your healthcare provider will monitor how well the medication controls your heart rhythm and whether you develop any side effects.

Increasing the Dose

If additional control is needed and Rythmol is well tolerated, your healthcare provider may gradually increase the dose.

The dose may be increased after at least 3 to 4 days to:

  • 225 mg every 8 hours, for a total of 675 mg per day
  • 300 mg every 8 hours, for a total of 900 mg per day, if additional treatment is needed

Doses above 900 mg per day have not been established as safe and effective for regular propafenone tablets.

Take Rythmol Regularly

Take Rythmol exactly as prescribed and follow your dosing schedule carefully.

Do not take more medication, take it more frequently, or change your dose without speaking with your healthcare provider.

Because Rythmol affects the heart’s electrical activity, changing the dose on your own could increase the risk of an abnormal heart rhythm.

Regular Heart Monitoring

Your healthcare provider may perform an electrocardiogram (ECG) before and during treatment.

Rythmol can sometimes cause new abnormal heart rhythms or make an existing rhythm problem worse. ECG monitoring helps your healthcare provider determine whether your dose remains safe and effective.

Liver Problems

Tell your healthcare provider if you have liver disease.

Rythmol is processed by the liver, and liver impairment can increase the amount of medication in your body. Your healthcare provider may need to reduce your dose or monitor you more closely.

Older Adults

Older adults and patients with significant heart muscle damage may need their dose increased more slowly.

This allows the healthcare provider to monitor the effects of Rythmol carefully before increasing the dose further.

Do Not Stop Rythmol on Your Own

Do not suddenly stop taking Rythmol or change your dosing schedule without speaking with your healthcare provider.

Stopping an antiarrhythmic medication may allow the abnormal heart rhythm to return or worsen.

What to Do If You Miss a Dose

If you miss a dose of Rythmol, take it when you remember unless it is almost time for your next scheduled dose.

If your next dose is due soon, skip the missed dose and continue with your regular schedule.

Do not take two doses at the same time or take extra Rythmol to make up for a missed dose.

New or Worsening Heart Rhythm Problems

Rythmol can sometimes cause a new abnormal heart rhythm or make an existing arrhythmia worse.

Because of this risk, your healthcare provider may perform an electrocardiogram (ECG) before treatment and during therapy.

Seek medical attention if you develop new or worsening palpitations, fainting, severe dizziness, chest pain, or shortness of breath.

Heart Failure

Rythmol may worsen heart failure in some patients.

It should not be used in people with uncontrolled heart failure. Tell your healthcare provider if you have a history of heart failure, swelling in the legs, increasing shortness of breath, or rapid weight gain.

Slow Heart Rate and Heart Block

Rythmol can slow electrical conduction through the heart.

It may cause:

  • Slow heart rate
  • First-degree heart block
  • More serious conduction problems

Rythmol should not be used in people with certain electrical conduction disorders unless they have an appropriate pacemaker.

Low Blood Pressure

Rythmol should be used cautiously in people who are prone to low blood pressure.

It is contraindicated in patients with marked hypotension. Contact your healthcare provider if you develop severe dizziness, fainting, weakness, or lightheadedness.

Brugada Syndrome

Rythmol may uncover Brugada syndrome, an inherited condition that can cause dangerous heart rhythms.

Your healthcare provider may use ECG monitoring after treatment begins to look for signs of this condition.

Grapefruit

Avoid grapefruit and grapefruit juice unless your healthcare provider says it is safe.

Grapefruit can affect CYP3A4, one of the enzymes involved in breaking down Rythmol, and may increase the amount of medication in your body.

Higher Rythmol levels may increase the risk of side effects or heart rhythm problems.

Drug Interactions

Rythmol can interact with many medications.

Important interactions may occur with:

  • Other antiarrhythmic medications
  • Medications that prolong the QT interval
  • Digoxin
  • Warfarin
  • Certain antidepressants
  • Some antibiotics or antifungal medications
  • Medications that inhibit CYP2D6 or CYP3A4

Rythmol can increase digoxin and warfarin levels, while some other medications can increase the amount of Rythmol in your body. Tell your healthcare provider about all prescription medications, over-the-counter products, vitamins, supplements, and herbal products you use.

Liver Problems

Tell your healthcare provider if you have liver disease.

Rythmol is extensively processed by the liver. Liver impairment can significantly increase the amount of medication in the body, which may increase the risk of side effects.

Your healthcare provider may need to reduce your dose and monitor you more closely.

Kidney Problems

Tell your healthcare provider if you have kidney disease.

Although Rythmol is mainly processed by the liver, some metabolites are removed through the kidneys. Your healthcare provider may monitor you more closely if kidney function is reduced.

Myasthenia Gravis

Tell your healthcare provider if you have myasthenia gravis.

Rythmol has been reported to worsen muscle weakness in people with this condition, so careful monitoring may be needed.

Dizziness and Reduced Alertness

Rythmol may cause dizziness, lightheadedness, blurred vision, or fatigue.

Use caution when driving, operating machinery, or performing tasks that require alertness until you know how Rythmol affects you.

Vision Changes

Blurred vision and other visual disturbances may occur during treatment.

Contact your healthcare provider if you develop new, persistent, or worsening changes in your vision.

Low White Blood Cell Counts

Rarely, Rythmol may cause agranulocytosis, a severe reduction in certain white blood cells.

Contact your healthcare provider promptly if you develop:

  • Fever
  • Chills
  • Sore throat
  • Unusual infections

Blood tests may be needed if these symptoms occur.

Pregnancy

Tell your healthcare provider if you are pregnant, think you may be pregnant, or plan to become pregnant.

Rythmol should be used during pregnancy only when your healthcare provider determines that the expected benefit outweighs the potential risk.

Do not stop Rythmol on your own if you become pregnant.

Breastfeeding

Tell your healthcare provider if you are breastfeeding or plan to breastfeed.

Your healthcare provider can help determine whether Rythmol is appropriate based on the benefits of treatment and any potential risk to the nursing infant.

Regular Heart Monitoring

Because Rythmol directly affects the heart’s electrical system, regular monitoring is important.

Your healthcare provider may check:

  • Heart rhythm with an ECG
  • Heart rate
  • Blood pressure
  • Pacemaker function, if applicable
  • Liver function
  • Other medications that may interact with Rythmol

Regular monitoring helps make sure your treatment remains safe and effective.

Does Rythmol affect blood pressure?

Yes. Rythmol can lower blood pressure in some people and may cause dizziness, lightheadedness, weakness, or fainting. The risk may be greater if you are dehydrated because of vomiting, diarrhea, heavy sweating, or not drinking enough fluids. Contact your healthcare provider if you develop severe dizziness, fainting, or symptoms of very low blood pressure.

How do I stop taking Rythmol?

Do not stop Rythmol on your own. Stopping treatment may allow your abnormal heart rhythm to return or become worse. Your healthcare provider will decide whether Rythmol should be stopped and whether any change in treatment is needed. Do not reduce the dose or change your dosing schedule unless your healthcare provider tells you to.

Can Rythmol affect fertility?

Rythmol may reduce sperm count in some men. This effect may be reversible after the medication is stopped. Talk to your healthcare provider if you have concerns about fertility while taking Rythmol.

How long does Rythmol take to work?

Rythmol begins affecting the heart’s electrical activity after a dose is taken, but the time needed to control an abnormal rhythm depends on the condition being treated and the dosing plan. In some medical settings, propafenone has been used as a single oral loading dose to convert recent-onset atrial fibrillation, with effects sometimes occurring within a few hours. However, this type of treatment should only be used when specifically prescribed and monitored by a healthcare provider. Do not take an extra or loading dose on your own.

Can I take Rythmol on an empty stomach?

Yes. Regular Rythmol tablets may generally be taken with or without food. Try to take each dose the same way every day and at evenly spaced times, usually every 8 hours when prescribed three times daily. If Rythmol causes stomach upset, ask your healthcare provider or pharmacist whether taking it with food may help.
