The traditional medical approach for controlling hallucinations is
the administration of antipsychotic drugs. However drugs are only
partly successful in controlling the hallucinations associated with
psychotic disorders; they often reduce the more florid symptoms
of a dysfunction but do not necessarily totally eliminate
hallucinations.3,4,5 About 20% to 40 % of patients continue to
experience persistent hallucinations inspite of treatment with
psychotropic medications.6
