It's not clear what you mean by taking too much Madopar. Our Drug treatments for Parkinson's booklet lists some other possible side effects including loss of appetite, sleep and psychological problems. It also says that not everyone will have dyskinesia when taking this drug.
Do have a look at the booklet. If you're worried about your dosage or a side effect, speak to your Parkinson's nurse. Or, you can call a nurse on our helpline team at 0808 800 0303.
I hope that helps
