Depends on drug: This is a complex issue. Different antipsychotic drugs are metabolized in different rates in the body, and other factors may affect this, such as interactions with other drugs you are taking (Klonopin, Motrin, or herbal supplements). You should NOT abruptly stop any antipsychotic drug. Check with Dr who prescribed meds to learn appropriate way to taper off these meds. Good luck!
