Extrapyramidal symptoms resulting from risperidone use in a four year old child: A case report.

Extrapyramidal symptoms (EPS) are the major constraint in the use of antipsychotic agents. It is usually forewarned whenever therapy with these agents is considered. In this case, we present a child diagnosed with relapsed Wilm's tumour, who developed EPS just after a short duration of initiation of risperidone prescribed as an appetite stimulant. The patient became symptom free after management and risperidone was discontinued. Although risperidone has been approved to treat different indications in adolescents and children, scarce scientific evidence and our case report, are suggestive of further studies to establish safety of risperidone use in preschool children.
