Lithium is used as a mood stabiliser. Here we report a case of bipolar disorder on Lithium and Olanzapine presented with fever, generalised rigidity and unconsciousness. He was diagnosed as Neuroleptic malignant syndrome (NMS). His serum lithium level was elevated. Lithium associated NMS usually occurs only in combination with antipsychotics at around 0.01-3%.
