Mild Hypothermia in a Child with Low-Dose Risperidone.

Risperidone is a widely used, second-generation antipsychotic approved for treating schizophrenia as well as for treating aggression in children and adolescents with mental retardation. The substance has a well-established risk profile including alterations of body temperature. Apart from hyperthermia with and without full-blown malignant neuroleptic syndrome, low body temperatures (hypothermia) have also been reported anecdotally, usually appearing in the context of comedication. Here, we report a case of hypothermia associated with a low-dose risperidone monotherapy in a child.
