Everybody is different when it comes to side effects of a particular drug. Some people even don't show any side effects for one particular drug whereas others show mild or significant concerns. Therefore, I would suggest her to reconsider her decision and try chlorpromazine as prescribed. After all, it is Schizophrenia and you cannot simply ignore it. Such negligence could worsen the situation for Jim and you all.
