I've been on dopamine agonist Requip XL (ropinirole) since August last year. Built up slowly from 2mg to current 12mg. It's helped a lot with movement; i go to the gym and wonder if i would be able to if i wasn't on it. (Can't answer that as i didn't start gym til 4mths after starting tablets)
My only side-effects started at about 6mgs and that was nausea and bit of dizziness (more like spaced-out-ness) but only for a few days each time the dose was increased, then it wore off and i was fine. I told my son about potential ocd just in case, but i haven't had any change in behaviour or character. (Although i told my neuro i have enjoyed noticing hunky, young gym instructors while i work out, which could be classed as inappropriate behaviour at my age, but as i only enjoy the view, he recommended I continue and consider it as therapeutic!)
Just a note to add, this last week i have had some quite dizzy days, which worried me in case it was the meds suddenly not suiting me; saw doc today, turns out its an inner-ear thing, nothing to do with pd or meds! That reminded me not to automatically assume something is a side-effect!
Good luck! B
