Amoxapine-induced tardive dyskinesia.

A case report of amoxapine-induced tardive dyskinesia following discontinuation of amoxapine therapy is reported. During 68 weeks of therapy, the patient received a maximum of amoxapine 400 mg/d. Six months after amoxapine discontinuation, the patient continued to have symptoms of tardive dyskinesia. These symptoms correlate with the dopamine receptor-blocking property of amoxapine and its metabolites. We propose that amoxapine therapy be monitored for the long-term as well as the short-term adverse effects of dopamine receptor-blockade.
