Neuroleptic malignant syndrome and risperidone: a case report.

OBJECTIVE

To describe a case of neuroleptic malignant syndrome associated with risperidone.

CLINICAL PICTURE: An elderly patient with bipolar affective disorder presented with neuroleptic malignant syndrome and relapse of hypomania after commencing risperidone.

TREATMENT: Risperidone was ceased and the patient monitored closely.

OUTCOME: The symptoms of neuroleptic malignant syndrome were resolved.

CONCLUSION

To our knowledge this is the first such case reported, and suggests that risperidone, like other neuroleptics, is associated with neuroleptic malignant syndrome.
