Reconsidering Olanzapine as a Possible Culprit for Drug Fever, defying "Incomplete Neuromalignant Syndrome".

This case is important because it is the first time Olanzapine-induced fever has been described in the absence of neuroleptic malignant syndrome. In the context of the available antipsychotics with the atypical agents dominating the pool, only few of those are known to be well tolerated among the patients. Fever may be looked at by the physicians as a minor problem yet, it can be disabling to the large set of patients. Fever was not considerably listed as one of the side effects for Olanzapine and should not be confused with the incomplete neuromalignant syndrome.
