Hallucinations suddenly stopped prior to administering an antibiotic. I am wondering if anyone has had experiences with this problem ... the lady I care for is very spoiled and often manipulative. About 2 weeks ago she woke up in the wee hours on thurs. morning screaming hysterically, when I went in her room she said she was seeing people (but was more excited than afraid). She continued with this behavior for about 26 hours straight. I left at 5 am the next morning (Friday) to be with my daughter at the hospital, she was still displaying this behavior. By 5 pm when I got home, she had quit and never had another "hallucination". A urinalysis was done Friday afternoon, and it was positive for a uti, but she did not start her antibiotics until the following Monday (3 days later). I have had experience with elderly patients behavioral changes due to uti's, but have never seen them stop prior to the patient receiving the antibiotic. Thoughts, opinions or experiences, please anyone?
