My 66 year old sister is slipping, and the doctor suggests this medicine. She chokes frequently and her food goes into her lungs often, causing pneumonia. Her thinking isn't clear, she can barely sit up in a wheelchair. She is having trouble holding her head up too. She has no use of her legs, and only has a bit of use with her left hand. She has a urine bag, surgically implanted into her bladder, which she gets infections with from time to time. She has to be moved with a hoyer lift. Thank you.
