David, I tried Artane for about one year. My tremor got much better but I had severe side effects; mental confusion, memory loss, dry mouth, and vision impairment. Currently I am taking Amantadine. My tremor is contained with side effects not nearly as bad as when I was taking Artane. My mother who is 82 also has PD. She was taking Artane with good tremor control but because of severe hallunications the Dr. stopped the medication. I hope that this information helps. John [log in to unmask]
