The introduction of novel atypical antipsychotic medicines has raised new p
ossibilities in the treatment of psychotic patients. In particular, the dis
covery of pharmacologic agents that may ameliorate the most stubborn positi
ve and also negative symptoms without adding the burden of major side effec
ts is revolutionizing treatment expectations. However, it is also becoming
abundantly clear that successful treatment requires more than just the admi
nistration of a medicine. Treatment must also address the inner experiences
of the patient, as well as the social and psychological handicaps that are
associated with the illness. Some of the relatively neglected complication
s of using typical antipsychotic medicines include hyperprolactinemia and a
ntipsychotics that may require concomitant treatment with anticholinergic a
gents, which themselves have an array of side effects. This article present
s a detailed method for deciding when and how to use the new medications ef
fectively and how to manage the transition from one medicine to another.
