My mother was recently diagnosed with Parkinson's Disease. She is very elderly and my sisters and I have been taking care of her medically for years now. When she goes to the hospital for appointments, one of us goes with her. At the last visits, we discussed starting medication for Parkinson's soon, and the doctor mentioned madopar. Can anyone tell me more about this medications? Are there any side effects that we should know about? My mother has also had kidney problems in the past so I am concerned about that.
