My mother-in-law has dementia and we are in the process of having her placed in a home. We are concerned about all the medications she takes. We wonder if they may be contributing to her confusion. She s on Midodrine 5mg 3xday, Metopropol 25, Metformin, Diltiazem 360, Zoloft 25, Atorvastatin 40, Digox 25. She is 83. How can we find out what she needs and doesn t need? Rose.
