Fluoxetine Concomitant administration of propafenone and fluoxetine in extensive metabolizers increased the S-propafenone C max and AUC by 39% and 50% respectively and the R-propafenone C max and AUC by 71% and 50%, respectively.

It may also worsen premature ventricular contractions or supraventricular arrhythmias, and it may prolong the QT interval.

Use with Drugs that Prolong the QT Interval and Antiarrhythmic Agents The use of propafenone hydrochloride extended-release capsules in conjunction with other drugs that prolong the QT interval has not been extensively studied.

Such drugs may include many antiarrhythmics, some phenothiazines, tricyclic antidepressants, and oral macrolides.

Coadministration of fluoxetine with other drugs that are metabolized by CYP2D6, including certain antidepressants (e.g., TCAs), antipsychotics (e.g., phenothiazines and most atypicals), and antiarrhythmics (e.g., propafenone, flecainide, and others) should be approached with caution.

Drugs with a narrow therapeutic index represent the greatest concern (e.g., flecainide, propafenone, vinblastine, and TCAs).
