What Causes Hallucinations After Taking Medication For Pyelonephritis?

Im at the hospital with my wife, she was diagnosed with pyelonephritis, she was given levaquin when she first came in but after 2 days they changed the antibiotic to meropenum. We have been here for a week now, after the third day on these antibiotics she started hallucinating, getting agitated And talking to her self, so they gave her Geodome to calm her down, after that didn t work they gave her Ativan. She still hasn t improved and the doctors her are not able to tell us why she is still Aggited and hallucinating. I decided to tell the doctor and nurse not to giver her anymore of those medications for calming down bipolarism because it appears it s making her worse it s been over 24 hours and she is still agitated and hallucinations and has not slept. What can I do to figure out what to do next? Should we give her more adtivan to help her relax for the night
