Hi, I mostly just read and get information from the list serve, but my father has some questions regarding "Amantadine." I hope I'm spelling it correctly. He is presently on Artane and not getting much relief from it. He's only real symptom as so far is a tremor in his left hand and nothing seems to help him. So now he would like to know about "Amantadine", like the side effects, dosage, effectiveness, etc. Also he would like to know about Symmetrel - this could be wrong spelling as well - is this they same as "Amantadine" or something else? Or is there some other medication that could help his tremor? Thanks so much! Jo-Ann Obrand, father 63/3 yrs [log in to unmask]
