Have Alzheimer And Diarrhea. Prescribed Codein And Acetaminophen. Can I Take Her To Emergency?

My 80 year old mother who has had alzheimers for 12 years now has had diarrhea for 4 weeks now. She lives in a care facility and some of her her meds were switched to liquid meds (liquid calcium, multivitamin, codeine and acetominophen). She is not getting better. I am terrible worried as everything is eating which is not much is going right thru her. Her doctor who comes into the home is fairly new to her, but is only in the home 2x per week and many days are going by in-between. I am considering taking her into emergency so something will get done. Is that a good idea or shall I continue let them try to figure it out even tho its taking too long in my mind.
