Summary

Why it happens
Additive noradrenergic effects from reuptake blockade, plus possible inhibition of tricyclic metabolism by methylphenidate.
What to do
Monitor blood pressure, heart rate and tricyclic adverse effects, and reduce the amitriptyline dose if toxicity appears. Consider tricyclic serum level monitoring when the combination is needed.
