Thanks for your input. I am presently taking Sinemet CR (Carb/Levo ER Tab 50/200 so I don't know if that is the same as Stalevo. It is suppose to be long lasting but I didn't get the benefit so I have increased my dose of Carb/Levo 25/100 for the immediate impact I need. My Movement Disorder Neurologist believes I can get same if not better benefits from the Rytary and not have to take a dose so often. It is the expense I am wondering about so I need to work with my Rx Part D source to see what they will charge.
