Neuroleptic malignant syndrome without fever after addition of oxcarbazepine to long-term treatment with amisulpride.

Objective: Our goal was to report a case of malignant neuroleptic syndrome in a patient administered with both oxcarbazepine (OXCBZ) and amisulpride (AM).

Method: We present a case of a young man who presented with symptoms of malignant neuroleptic syndrome after progressive titration of OXCBZ (1,200 mg) added to the long-term treatment with AM (800 mg).

Results: After discontinuation of AM and administration of dopaminergic drugs, his clinical symptoms improved gradually.
