The evidence base for the use of antipsychotics to treat schizophrenia comes from research showing that the drugs are effective in treating acute symptoms (1), and that when the drugs are abruptly withdrawn, patients are at high risk of relapse (2). These studies, however, do not address whether continual long-term use leads to better overall outcomes.
