Rythmol

The active ingredient in Rythmol SR is propafenone hydrochloride, which is an antiarrhythmic. The mechanism of action involves obstructing sodium channels, which are crucial for the electrical activity of your heart. To treat irregular beats, it reduces the heart's abnormal electrical activity.

Follow all directions given to you by your doctor and read all documents provided, including the full Prescribing Information, FDA-Approved Product Labeling, Instructions for Use, and Medication Guide before using Rythmol SR. However, the following is a synopsis of the general guidelines for the use of Rythmol SR:

• Rythmol SR can be taken with or without food.
• When using this drug, your blood pressure may drop extremely low. If you have diarrhea or vomiting, excessive thirst, appetite loss, or excessive perspiration, call your doctor.
• You could require blood tests regularly.
• An electrocardiogram, or ECG, may also be required to assess your heart function both before and after Rythmol SR treatment in individuals with hepatic (liver) dysfunction, asthma, congestive heart failure, or bradycardia.

The most common side effects of Rythmol SR seen in clinical trials as compared to placebo include:

• Dizziness.
• Palpitations (fast or irregular heartbeats).
• Shortness of breath.
• Constipation.
• Blurred vision.
• Low white blood cell levels (agranulocytosis).
• Low blood pressure (hypotension).

Some individuals may experience serious side effects while using Rythmol SR. These side effects may require immediate medical attention. If you experience any of the following, contact your healthcare provider or seek emergency medical help:

• Chest pain (angina) or discomfort, weakness, lightheadedness, or fainting are signs of an irregular heartbeat.
• Unexpected weight gain, fluid accumulation in the legs or feet, or increased shortness of breath, particularly when lying down, and sudden weight gain are signs of new or worsening heart failure.
• Fever, chills, and sore throat are signs of infection.
• Allergic reactions to the medication such as hives, swelling of the face, tongue, or throat, and trouble breathing.

These are not all of the possible adverse reactions of Rythmol SR. You should always seek medical advice from your healthcare provider for any questions or concerns about your medical condition or treatment. Read all patient information, medication guides, or drug information sheets that come with this medication. You can also report adverse effects to the Food and Drug Administration at www.fda.gov/medwatch or 1-800-FDA-1088.

• A severe cardiac ailment like "AV block" or "sick sinus syndrome" (unless you have a pacemaker).

• Diseases of the lungs that impair breathing, such as COPD, or chronic Obstructive pulmonary disease.
• Levels of electrolytes that are not balanced.

Rythmol SR typically takes 10 to 50 hours to leave your system, according to its half-life. However, some people's genetic makeup causes them to break down the medicine more slowly. It may take up to a week for your body to process the drug if you fall into this category.

When Rythmol SR is taken with other prescription drugs, over-the-counter medications, vitamins, and supplements, it may change how they work or increase the incidence or severity of side effects. Make sure that you tell your healthcare professional about anything that you are taking to avoid any negative drug interactions, including:

• Digoxin.
• Warfarin.
• Amiodarone.
• Ketoconazole.
• Flecainide.
• Cimetidine.
• Erythromycin.
• Fluoxetine.
• Quinidine.
