Summary
Escitalopram can prolong the QT interval in a dose-dependent manner, and propafenone has proarrhythmic effects and prolongs conduction. Propafenone may also raise escitalopram levels through CYP2D6 inhibition. Together these increase the risk of ventricular arrhythmia, especially with other risk factors.
What this interaction means in plain words
Escitalopram and Propafenone 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.
Escitalopram belongs to Central Nervous System; Propafenone belongs to Cardiovascular.
Why it happens
Additive QT and conduction effects, with possible CYP2D6 inhibition by propafenone raising escitalopram levels.
What to do
Check ECG at baseline and after dose changes, and correct potassium and magnesium abnormalities. Keep escitalopram at the lowest effective dose.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
