checking Amitriptyline and Nortriptyline: no hard conflicts (1 to watch), but the amber pairs carry interactions to be careful with.
stacking anticholinergics adds up (dry mouth, constipation, blurred vision, confusion); a high anticholinergic load is linked to delirium and, long-term, to cognitive issues.
