Mr. McCarthy After being around Parkinson's and neurologists for 13 years, I can tell you that Senemet does not take away tremors. It actually causes them. What it does do is help with motor function & rigidity and freezing. The dyskinea's (sp?) or tremors are actually a side effect from the senemet - besides of course being caused also by Parkinson's My husband has his tremors eliminated by a Palladotomy several years ago (on one side) and they never came back but it did not stop the progression of Parkinson's. The rigidity and freezing; shuffling and on and off of the Senemet continues. We are on 9 25/250 a day. Carol
