The aim of this case report is to highlight that risperidone
may cause and ameliorate tardive dyskinesia. A 16 year old white women
with a 12 month history of schizophrenia, developed buccolingual masticatory tardive dyskinesia after receiving risperidone 6 mg. She
had received small dosages of typical antipsychotics before and during
receiving risperidone for short periods. Recommencement of risperidone
with 2 mg and increasing to 6 mg resulted in improvement in tardive
dyskinesia and up until now she remains free of any abnormal
involuntary movements.
