My Dr prescrived Nortriptyline for my arthritic neck concerns. I read that it is an antidepressant, and am concerned that it may cause more problems than it will help. He prescribed it because of my concern about the NSAID i am taking for it (prescription nabumetone 750), not being effective enough, and my neck also causing sleeping trouble. I don t doubt the Doc., but would love to hear more on this. Thanx, Sam
