Risperidone acts by potent serotonergic, dopaminergic and alpha adrenergic receptor antagonism. The most common side effects reported are extrapyramidal symptoms, dizziness, sedation, insomnia, headache, anxiety, nausea, constipation and weight gain. Oedema associated with risperidone use is a rare side effect. Here we present a report on pedal oedema associated with use of oral risperidone 4 mg per day for acute-onset psychotic illness. Through this case report we want to make clinicians aware about this important side effect as it can affect patients' compliance and quality of life.
