I have been taking Amitriptyline for almost 2 years. At the beginning of treatment I noticed itching on the top of my feet, then on my fingures, turning into a reddness like the beginning of a rash. In the past year the itching increased, rash spread over top of hands, elbows and top of feet, I was seen by a doctor who did not know what was causing the rash and itchiness, but gave me prednisone (?) a steroid. The rash cleared somewhat. About 3 months ago, my doctor changed the prescription to Nortriptyline and the rash symtoms returned spreading over my face, neck,shoulders, arms, and is more severely itching, reddness and scaly. I was not aware of the side effects of this medication until I just did research on it, realizing it could be the reason for the rash, itching, scaling. My question is 1. Can I discontinue the medication abruptly, and 2. is there an otc medication that I can buy right away until I can get into see the doctor?
