Dear Kat,
I do know that taking Requip itself can cause hallucinations. But he's been taken off it. Now, stopping Requip can cause confusion. So, I don't know what to make of it. I do recall when I had pneumonia, I was out of my mind, and I have never taken Requip. I suppose it's possible he's having a combination of fever hallucinations, left-over Requip hallucinations, and withdrawal confusion. Any way you look at it, he's having a very hard time.
