There is no direct interaction between flecainide and rivaroxaban. However, because both drugs are used to treat heart rhythm problems (like atrial fibrillation), they are often prescribed together. Flecainide controls the heart's rhythm, while rivaroxaban prevents blood clots. Taking them together does not change how either drug works in the body.

Why this happens
Flecainide is primarily processed by a liver enzyme called CYP2D6, while rivaroxaban is processed by different pathways (CYP3A4 and P-gp). Because they use different 'routes' for metabolism and have different targets in the body (one affects electrical signals, the other affects blood clotting), they do not interfere with each other.
What you should do
You can safely take these two medicines together as prescribed by your doctor. Ensure you attend your regular heart check-ups and blood tests. If you notice any unusual bruising or bleeding (common with rivaroxaban) or feel new heart palpitations (related to the condition flecainide treats), contact your healthcare provider.

Patient picks for Drug interactions
Traitement et médicaments
Can I take Esomeprazole and Trazodone together?
Esomeprazole may reduce the amount of trazodone that your body absorbs. This could potentially make trazodone less effective at treating your symptoms (such as depression or sleep issues). Additionally, both medications can rarely affect the electrical activity of your heart, though this risk is generally low.

Can I take Ibuprofen gel 10% and Shortec together?
Using ibuprofen gel alongside Shortec (oxycodone) is generally safe, but there is a small risk of increased side effects such as drowsiness, dizziness, or stomach irritation if the ibuprofen is absorbed into the bloodstream in significant amounts.
