From what I've been reading, it seems that taking a dopamine agonist versus levadopa is a "one or the other" choice. My neurologist has me taking 8 mg ropinirole hcl er once a day (at nighttime) and 25/100 caridopa/levadopa three times a day (breakfast, lunch and dinner). Is this combination of an agonis and levadopa a common treatment for pd? I am 67 years old, diagnosed almost 4 years ago. I have only been on the c/l for a few weeks.
