Hi I have been on Nortriptyline for almost 3 months I worked up to taking 75mg. but, my dose was lower as it was used to treat headaches. It did not treat my headaches and now I'm coming off of it...slowly, I am now down to 25mg. as of tonight!
I'm not sure how depression, I would thing that becuase it is one of the older drugs used to treat depression (Tricyclic Antidepressants, first depression med.) but, it could work everyone is different and reacts differntly.
While on Nortriptyline I became depressed though I'm not sure if it was the caused by the Nortriptyline or becuase of chronic pain.
I didn't have any side effects untill I was tkaing 50-75mg. All I had was dry mouth, and it cuased my blood pressure to drop untill I was getting really dizzy.
Kepp track of your side effects and be prepared to give it time to work.
If it's dosen't you can dicuss trying a SSRI's (Selective Serotonin Reuptake Inhibitors).
Or you could consider Wellbutrin which the neurotransmitters; dopamine and norepinepherine.
(but if you all ready tried the one's I've listed, there are lots of options and you might even have to combine different ones)
But, I'll keep my fingers crossed for you that that Nortriptyline will work.
