My 91 yr old Mom began taking Bactria a week ago today when her PCP found there was E. coli in her urine. On W my 91 year old Mom fell in her bathroom and broke 3 ribs. She spent one night in the hospital and was sent home with Norco 325mg. She seemed to be gradually progressing until Sat am when she became delusional, reaching for things that weren't there, having conversations with people who weren't there and being very agitated at times and drowsy at others but talking almost constantly. She has had no more Norco and has only gotten worse. The only other new med she is on is Entresto which replaces her Lisinopril after two days off the L. She has had scads of tests in the hospital, all negative. Any ideas?
