one benefit for some patients receiving continuous delivery of l-dopa via infusion -dupdopa, in which i assume carbidopa is delivered in the same amounts as oral delivery, is reduced dyskinesias. there was a study done in the last few years where carbidopa was increased to i think 400mg and there was a small benefit.

keep in mind not every advanced pd'er receiving C/L get dyskinesias. i've read that dyskinesias have been reported by people receiving apomorphine. so i wouldn't say this theory is a slam dunk.

this anonymous first time poster poster didn't mention how much C/L he was taking, other meds andf supplements he/she was taking when the dyskinesias started and what efforts were made to moderate them.
