My father 73 years old has just been detected with parkinson's last month. He felt like he was standing on a ball all the time that's when we decided to take him to a neurologist. He prescribed syndopa half a tab 3 times a day to start with. My father showed signs of improvement so the neurologist increased the dose to 3 tabs a day. Since the increased dosage my father's condition has become worse, he can't even stand properly and falls down as soon as he tries to get up. He has not been eating and has not passed stool for 5 days instead he vomits. We got his blood tests done and his hemoglobin came to 7 and according to doc that why the medication is not working. His ferritin has come to 1000 in the report. Please help and advise.
