My 97-year old mother has been taking Aricept (10 mg. once daily) and original Namenda (10 mg. twice daily) in generic form for about eight years. She is now in the advanced stage of Alzheimer's Disease. Can I safely discontinue one or both of these drugs at this point. My understanding is that the symptomatic relief they provide does not last long. I have continued dispensing these drugs for fear that mom might decline more rapidly without them and because they are covered by her Medicare Part D Drug Plan. On the other hand, less medication is always better than more. I welcome all comments on this subject.
