Emergence of tic disorder in a pediatric patient associated with risperidone and aripiprazole treatment

Abstract

An atypical anti-psychotic drug, risperidone, used in the treatment of schizophrenia, bipolar mania and irritability associated with autism spectrum disorder works primarily by inhibiting serotonergic (5-HT2A) and dopaminergic (D2) systems. 1 Common adverse effects include cerebrovascular events, tardive dyskinesia, neuroleptic malignant syndrome, orthostatic hypotension, cytopenia, Parkinson-like symptoms, motor impairment, seizures, metabolic alterations and hyperprolactinemia.
