Please look back at posts about Ropinirole on the forum.
Are your symptoms so bad that you need medication now?
20 years ago, and, knowing no better, OH was prescribed Ropinirole straight away. 18 months later OH was on 24mg/day, the highest dose when in reality they did not need this at that time.
Ropinirole may reduce your symptoms in the short term but please look up the long term effects and actually how diffiicult it may be getting off this drug in the future. Question why you have been prescribed this drug and be armed with all the information that you can gather about it. There's plenty on this forum alone.
