Summary
Androgen deprivation with triptorelin may prolong the QT interval. With flecainide, which affects cardiac conduction, the risk of ventricular arrhythmia may increase in patients with other risk factors.
What this interaction means in plain words
Flecainide and Triptorelin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Flecainide belongs to Cardiovascular; Triptorelin belongs to Endocrine.
Why it happens
Additive pharmacodynamic effects on cardiac repolarization and conduction; testosterone suppression is linked to QT prolongation.
What to do
Obtain a baseline ECG and repeat periodically, correcting potassium and magnesium. Reconsider therapy if QTc or QRS lengthens markedly.
