I think each drug is different for everyone. I had my first psychotic break on Prozac. I was not diagnosed bipolar at the time so my doc didn't know to try mood stabilizers. Prozac made me hallucinate my imaginary friend from childhood in the room w me and he was telling me to cut myself. I did. Luckily my roommate came home and found me. He dosed me w xanax and hung out w me until I calmed down.
