Summary
Tricyclic antidepressants block norepinephrine reuptake and can potentiate the pressor effects of sympathomimetics. Systemic absorption of intranasal xylometazoline is low, so the effect is usually small, but hypertension or arrhythmia may occur with excessive use.
What this interaction means in plain words
Amitriptyline and Xylometazoline 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.
Amitriptyline belongs to Central Nervous System; Xylometazoline belongs to Respiratory.
Why it happens
