You should not take this medication if you have recently had a heart attack, or if you are allergic to nortriptyline or to similar antidepressants such as amitriptyline, amoxapine, clomipramine, desipramine, doxepin, imipramine, protriptyline, or trimipramine.

I ve been taking amitriptyline to see if it improves frequent and severe migraine, having tried many other things in the past.
