Safely Buy Rythmol SR ( Propafenone Hcl ) from Canada Prescriptions Plus.

Indications

This medication is used to help prevent certain types of serious (possibly fatal) irregular heartbeat (such as paroxysmal supraventricular tachycardia and atrial fibrillation).

Propafenone is known as an anti-arrhythmic drug. It 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 of blood clots, and this effect can reduce your risk of heart attack or stroke.

Use and Dosage

Read the Patient Information Leaflet if available from your pharmacist before you start taking propafenone extended-release capsules and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with or without food as directed by your doctor, usually every 12 hours. Swallow the capsules whole. Do not crush or chew the capsules. Doing so can release all of the drug at once, increasing the risk of side effects.

The dosage is based on your medical condition and response to treatment.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.

• Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/”water pills”) or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using propafenone safely.
