My dad has been on carbidopa levodopa for 5 yrs. He's 84 with parkinson's plus lewy body dementia. He's on hospice at home. I've had to wean him down from 4pills to 2. 30 mins after taking it, he goes into severe delusions and tries to get out of the door, thinks i'm plotting, says i'm putting nails in the bed, injecting him, etc. It's a mess. No antipsychotic med works. Psychosis is bad too. He says the pills are making him crazy and I need to watch him more or he'll be walking the streets. Hospice just says more meds...
