In an acute psychotic episode, higher doses of antipsychotics are administered to suppress the psychotic content that prevents your brother from functioning normally.
Since he hasn't been on antipsychotics recently, these high doses are naturally causing more noticeable side effects. These will subside as the medication levels stabilize and his body adjusts; eventually, the therapeutic benefits will outweigh the side effects, even if it doesn't seem that way to you right now.
You cannot reason with someone in an acute psychotic state, and you shouldn't expect a psychiatrist to engage with delusions regarding poisoning, surveillance, or aliens. Once the medication brings him back to reality, then communication can occur.
Certain antipsychotics (mostly "older" ones like Haldol or Moditen, though newer ones can too) may cause muscle stiffness or cogwheel rigidity, but this is managed with an injection or pill of Artane.
