Table of contents:

Rythmol SR is an oral medication used as a Class IC anti-arrhythmic to affect the way the heart beats and prevent serious irregular heartbeats such as paroxysmal supraventricular tachycardia and symptomatic atrial fibrillation. It contains the active ingredient propafenone hydrochloride and is available in extended-release capsules for oral use. Propafenone is known as an anti-arrhythmic drug.

Rythmol SR 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 and Dosage

Rythmol SR capsules should be taken orally with or without food every 12 hours as prescribed by your doctor. Swallow the capsules whole and do not crush or chew them, as doing so can release all the drug at once and increase the risk of side effects.

Avoid eating grapefruit or drinking grapefruit juice while using Rythmol SR unless your doctor or pharmacist says you may do so safely. Grapefruit can increase the chance of side effects with Rythmol SR. Ask your doctor or pharmacist for more details.

To ensure the medication's effectiveness, it should be taken regularly at the same times each day. Avoid consuming grapefruit or grapefruit juice while using Rythmol SR, as it can increase the chances of experiencing side effects. Please consult with your doctor or pharmacist for more information.
