As the usage of such atypical antipsychotic medications in adults and children increases, the number of overdoses and unintentional ingestions will continue to grow.The adverse consequences of olanzapine overdose are compounded in psychiatric populations because of numerous (yet seldom adequately diagnosed and treated) physical illnesses, intricate polypharmacy with high doses of psychotropic drugs and delayed or absent interventions.Olanzapine has a high volume of distribution (approximately 10-20 liters per kilogram) and the rate of metabolism can vary up to 20-fold among individuals. Expert conclusion found in the interdisciplinary guidelines for therapeutic drug monitoring in Therapeutic drug monitoring also has a value for preventing overdosing that can arise as a result of changes in treatment or environment of patients. Therefore olanzapine should be added to opioid and α2-adrenergic agonist intoxication in the differential diagnosis of the patient with depressed mental status and miosis (excessive constriction of the pupil of the eye).Deaths attributed to probable cardiac toxicity have been continuously reported from olanzapine overdose.

Older types of antiepileptic drugs, tricyclic antidepressants and lithium have a well-documented concentration-effect relationship, which is also known as a therapeutic window.Still, the evidence for a concentration-effect relationship is not so extensive for olanzapine, albeit it also exhibits curvilinear concentration relationship of clinical effects and potential adverse activities. We comply with the HONcode standard for trustworthy health information - Due to the extensive first-pass metabolism (up to 40%), large overdoses result in nonlinear pharmacokinetics leading to striking increases in blood concentrations.Most common symptoms that arise as a result of olanzapine overdose include central nervous system depression with somnolence, blurred vision, low blood pressure, respiratory depression, extrapyramidal and anticholinergic effects, as well as exceptionally high fever.Some studies point to the possibility of olanzapine overdose mimicking opiate intoxication.
