My Parkinson consultant put me on Mirtazapine because he said it would help relax my muscles,but when I picked up the tablets I noticed it was for depression so I was very reluctant to start them.I waited ten days before taking the plunge because the side effects seemed awful.But they have been such a help to me. I had terrible itching day and especially at night which kept me awake. Since taking the Mirtazapine I have no itching, and also I don’t need to take the sleeping tablet zopiclone,and added bonus too is my mood has brightened and I am much more positive about this blessed Parkinson’s disease.I have always had a delicate stomach and thought I would get some of the nasty side effects, but I have had none of them. The dose I have is the 15mg. I do hope this helps you.
