Thanks for choosing "Ask the Doctor" for posting your query.
I have gone through your question in detail and I can understand what you are going through.
I agree with your concerns that the dosage is high and that too in a very short duration Instead of running such high doses of a single medicine, it would be advisable to use other medicines of parkinsonism as well. Pramipexole or trihexyphenidyl or propranolol. may be added up to reduce the symptoms of parkinsonism. This will help in reducing the over dosage of dopa.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you in future.
Wish you good health!
