My 85-year-old father has been very ill with pneumonia and a UTI. For the most part, he is eating very, very little, and drinking even less. He is still taking his medications (including his antibiotics) by mouth and will communicate for a minute or two here and there. For the most part he is sleeping. This morning, his doctor abruptly discontinued his Aricept (without telling us--we found out as a fluke). The nurse said that he did it because often Aricept will cause a person to become very weak like this. My Dad has been on the Aricept practically since he was diagnosed with Parkinson's seven years ago. While his dementia is just now in the early stages, he was prescribed the Aricept "to enable his brain to more easily communicate with his body". It did help. Has anybody heard of removing a patient from Aricept for the reason the doctor gave? What is the ramifications of having the Aricept suddenly discontinued? Thank you all in advance for your replies and advice. This site is a blessing.
