Rythmol official prescribing information for healthcare professionals. Includes: indications, dosage, adverse reactions, pharmacology and more.

Propafenone has caused new or worsened arrhythmias. Because propafenone prolongs the QRS interval in the electrocardiogram, changes in the QT interval are difficult to interpret. It is therefore essential that each patient given Rythmol be evaluated electrocardiographically prior to and during therapy to determine whether the response to Rythmol supports continued treatment. It may also worsen premature ventricular contractions or supraventricular arrhythmias, and it may prolong the QT interval. Such proarrhythmic effects include sudden death and life-threatening ventricular arrhythmias such as ventricular fibrillation, ventricular tachycardia, asystole, and torsade de pointes.

These laboratory findings were usually not associated with clinical symptoms, but there is one published case of drug-induced lupus erythematosis (positive rechallenge); it resolved compley upon discontinuation of therapy.

Rythmol (Propafenone) Side Effects, Interactions, Warning, Dosage

RYTHMOL (propafenone hydrochloride) is an antiarrhythmic drug supplied in scored, film-coated tablets of 150 and 225 mg for oral administration. What are the possible side effects of propafenone (Rythmol, Rythmol SR)? Therefore, avoid simultaneous use of RYTHMOL with both a CYP2D6.

There were 5 deaths, 3 in the pooled RYTHMOL SR group (0.8%) and 2 in the placebo group (1.6%). Concurrent use of propafenone with other antiarrhythmic agents has not been well studied. In a study of sustained-release propafenone (RYTHMOL SR), there were too few deaths to assess the long term risk to patients. In the overall RYTHMOL SR and RYTHMOL immediate-release database of 8 studies, the mortality rate was 2.5% per year on propafenone and 4.0% per year on placebo.

It is therefore essential that each patient given RYTHMOL be evaluated electrocardiographically prior to and during therapy to determine whether the response to RYTHMOL supports continued treatment.
