I appreciate your concern about her, but this is a conversation you should be having with her physician. Ask, in particular, about home health assistance and also about drug interactions. This is assuming you have the capacity to act on her behalf. Do you? Because if you don't, then like it or not, you need to defer to the person who does (perhaps a parent of yours). If no one is so designated, this can turn into a legal matter. She is entitled to her medical privacy and is presumed to be competent enough to make her own medical decisions until proof is presented otherwise.
