Abstract:
It has been reported that risperidone, an atypical antipsychotic drug, is less likely to induce neurologic side effects than conventional antipsychotics. However, long-term administration of risperidone has been reported to produce severe irreversible neurologic side effects, such as tardive dyskinesia. Tardive dystonia has been suggested as a distinct movement disorder different from tardive dyskinesia and a few cases of risperidone-induced tardive dystonia were reported recently. We experienced two cases of tardive dystonia, which developed in association with the long-term administration of risperidone, and the symptoms of tardive dystonia were slightly subsided after discontinuation of risperidone. It is necessary to be cautious of dystonic symptoms during long-term administration of risperidone.
