Background
The effects of antipsychotic drug withdrawal have been inadequately studied. Case reports have described dyskinesia occurring in patients with several antipsychotics withdrawn, but studies on amisulpride withdrawal dyskinesia are lacking.
Case presentation
A 63-year-old man, who was diagnosed with schizophrenia at age 49, received amisulpride treatment since age 62. The dosage of amisulpride was reduced from 200 to 50 mg/day because of occurrence of akathisia during one admission. Severe withdrawal dyskinesia, mixed with dystonia and akathisia, was noted immediately after the dosage reduction. The abnormal involuntary movement showed improvement 2 weeks later when the dosage was increased to 100 mg/day.
Conclusions
Withdrawal dyskinesia and other abnormal involuntary movements could be noted in a patient with reduction of amisulpride dosage or sudden termination. Withdrawal dyskinesia may subsequently lead to persistent tardive dyskinesia. Therefore, withdrawal-emergent dyskinesia should be promptly identified, and appropriate medical interventions should be given early.
