For Alzheimer's Disease "We started my Dad on Namenda, and by day 2, he was more confused, lost, and irritable than usual, so my Mom stopped it. The doctor asked her to start again, and the same day, he experienced the same side effects, so she stopped. Last week, she decided to try it one more time to make sure. Dad was VERY confused and not easy to take care of. I guess he is just one of those people that can't take this medication. Too bad. It helps so many people."

For Alzheimer's Disease "My father has significantly improved since taking Namenda and Aricept combined, as well as 24-hour caregiver support at home. We believe that the combination has helped dad's cognitive function not just by medication alone, but because he had companionship 24 hours a day. Dad was confused, always thought he was at work and wanted to go home. He forgot who we were and even made sexual moves towards people he would not have otherwise when he did not have Alzheimer's. The symptoms or behaviors he still has are occasional memory loss but very little. He is still paranoid and thinks people are stealing from him or going on his property when they are not, and he occasionally still sees people or animals that aren't there. But the confusion of who we were, where he was, and the wandering and wanting to 'go home' even when he was home is no longer an issue. My dad is only 73, and he was diagnosed last year with Alzheimer's."

For Alzheimer's Disease "My mother has been treated with the Exelon (patch) for two years now. Last month she was changed to Namenda. She has become irritable, aggressive/depressed and more confused than before. We are asking the doctor to switch back to Exelon."

For Alzheimer's Disease "My mother has taken Namenda twice now. The first time she was so confused after a week, I stopped giving it to her. She has gotten worse over the years and for some reason her doctor had given me a new prescription for the same medicine. I tried it for two days and saw my mother become extremely confused, so I stopped giving it to her. I don't know why he insisted on Namenda after I told him it didn't work the first time."

For Alzheimer's Disease "My mom has been on this medication for one year, and her condition (dementia) is getting worse. She's hallucinating, aggressive, and extremely confused. It seems as if this medication is making things worse and speeding up the progress of the dementia. This drug should not be on the market. I will bring her to her psychologist soon, and I will be asking for this drug to be taken off her daily medication intake. Please say no to this drug."
