Polyarthralgia with oral risperidone.

Abstract

Risperidone is a commonly used antipsychotic. Due to its widespread use, health professionals are well aware of its common side-effects. However, there are some side-effects (though rare in practice) that are disabling, distressing and cause severe suffering to patients, and these can have the potential of being missed. Here the authors report one such side-effect of risperidone, namely polyarthralgia.
