What is the average time it takes to recover from having hallucinations and delirium?

Sometimes its pretty quick, other times meds are metabolized slow so it could be a week or so. But, if it gets worse rather than better or persists much after that, have another look medically at what else might be going on.

My experience with 84 yr old mom is that her mind gets better as soon as the meds for uti have begun working in a day or two.

My mom was hallucinating in the rehab center because she was on meds there to settle her down. That was 2 weeks ago. Now she's home and she isn't having the hallucinations anymore. I hope this helps a little.
