Most antipsychotics can be pretty nasty. I would call your pdoc before making any changes or stopping any drug, but I am wondering-- where is your paranoia coming from? Meaning, it is an anxiety paranoia or a psychotic paranoia? I have paranoia but it is manifested in anxiety-- meaning that I know my fears are irrational. I am completely aware that the things I am paranoid about are most likely not true. If it is paranoia rooted in psychoses, then you don't realize that your fears are irrational. Taking an antipsychotic is not something that would necessarily help with the anxiety type. That's definitely more of a therapy issue. Do you see a therapist?
