My fathers doctor had prescribed stalevo with 50mg levadopa 3 times daily. That meant he took 150mg levadopa each day. However we saw no improvement in his slowness and walking etc. So then the doctor switched him to madaopar but 125mg 3 times a day this means he would take 300mg levadopa each day. So the doctor increased the dose of daily levadopa from 150mg to 300mg instead!"is this increase normal or is it too much???
