My Brother Has Dementia, He Is 65 And Is Currently

My brother has Dementia, he is 65 and is currently in the Hospital, from side effects from Zyprexa, Doctor at the hospital is going to give him Haldol tonight, because he is really agitated, and needs something to relax him , for the last 3 days he has had no medicine, just giving him IV with fluids, I think he is showing signs that he is recovering from terrible side effects, like tremors, weakness, swelling, I am concerned after reading side effects of Haldol and t/hat it is not approved for the elderly, what do you think
