My uncle, age 84, who is not forthcoming with medical information, was diagnosed with dementia early last spring and prescribed Aricept and Namenda. My cousin (his daughter) who visited from out of state last week, discovered by accident that he had not been able to fill his Namenda prescription for at least three months. The local, small town pharmacy told him that they were not able to get it, and evidently did not contact the neurologist to ask about switching to Namenda XR. Now, my aunt has told my cousin that they got a new Rx on Tuesday and he is taking it again. Should he have had a new "starter pack" of increasing doses since he has not taken it for a period of time? Does anyone know why this med needs to be titrated? My uncle has not given permission for his doctor to give information to his children, and they do not know if the doctor is aware of this treatment gap.
