Withdrawal-emergent dyskinesia in a patient on risperidone undergoing dosage reduction.
A 23-year-old, white male with history of paranoid schizophrenia developed a withdrawal-emergent dyskinesia during a dose reduction of risperidone. The implications of this with regard to future risk of tardive dyskinesia (TD) and the potential association of risperidone with TD are discussed.
