🩺 Clinical
Olanzapine is used to treat schizophrenia (a mental illness that affects how a person thinks, feels and behaves) and bipolar I disorder (a disease that causes depression, mania, and other abnormal moods). Olanzapine is in a class of medications called atypical antipsychotics. It works by changing the activity of certain natural substances in the brain.

🚨 Boxed Warning ▾
WARNING: INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Analyses of seventeen placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in the placebo group.
Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Observational studies suggest that, similar to atypical antipsychotic drugs, treatment with conventional antipsychotic drugs may increase mortality. The extent to which the findings of increased mortality in observational studies may be attributed to the antipsychotic drug as opposed to some characteristic(s) of the patients is not clear.
Olanzapine is not approved for the treatment of patients with dementia-related psychosis. [see Warnings and Precautions (5.1), Use in Specific Populations (8.5) and Patient Counseling Information (17)]. When using olanzapine and fluoxetine in combination, also refer to the Boxed Warning section of the package insert for Symbyax. See full prescribing information for complete boxed warning. • Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. olanzapine is not approved for the treatment of patients with dementia-related psychosis (5.1, 8.5, 17) When using olanzapine and fluoxetine in combination, also refer to the Boxed Warning section of the package insert for Symbyax.

( 2.5 )
2.1Schizophrenia Adults Dose Selection — Oral olanzapine should be administered on a once-a-day schedule without regard to meals, generally beginning with 5 to 10 mg initially, with a target dose of 10 mg/day within several days. Further dosage adjustments, if indicated, should 4 generally occur at intervals of not less than 1 week, since steady state for olanzapine would not be achieved for approximately 1 week in the typical patient. When dosage adjustments are necessary, dose increments/decrements of 5 mg QD are recommended.
Efficacy in schizophrenia was demonstrated in a dose range of 10 to 15 mg/day in clinical trials. However, doses above 10 mg/day were not demonstrated to be more efficacious than the 10 mg/day dose. An increase to a dose greater than the target dose of 10 mg/day (i.e., to a dose of 15 mg/day or greater) is recommended only after clinical assessment.
Olanzapine is not indicated for use in doses above 20 mg/day. Dosing in Special Populations — The recommended starting dose is 5 mg in patients who are debilitated, who have a predisposition to hypotensive reactions, who otherwise exhibit a combination of factors that may result in slower metabolism of olanzapine (e.g., nonsmoking female patients ≥65 years of age), or who may be more pharmacodynamically sensitive to olanzapine [see Warnings and Precautions (5.14 ) , Drug Interactions ( 7 ), and Clinical Pharmacology ( 12.3 ) ].
When indicated, dose escalation should be performed with caution in these patients. Maintenance Treatment —The effectiveness of oral olanzapine, 10 mg/day to 20 mg/day, in maintaining treatment response in schizophrenic patients who had been stable on olanzapine for approximately 8 weeks and were then followed for relapse has been demonstrated in a placebo-controlled trial [see Clinical Studies (14.1) ]. The healthcare provider who elects to use olanzapine for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient.

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect or predict the rates observed in practice. Clinical Trials in Adults The information below for olanzapine is derived from a clinical trial database for olanzapine consisting of 10,504 adult patients with approximately 4765 patient-years of exposure to oral olanzapine.
This database includes: (1) 2500 patients who participated in multiple-dose oral olanzapine premarketing trials in schizophrenia and Alzheimer’s disease representing approximately 1122 patient-years of exposure as of February 14, 1995; (2) 182 patients who participated in oral olanzapine premarketing bipolar I disorder (manic or mixed episodes) trials representing approximately 66 patient-years of exposure; (3) 191 patients who participated in an oral olanzapine trial of patients having various psychiatric symptoms in association with Alzheimer’s disease representing approximately 29 patient-years of exposure; (4) 5788 additional patients from 88 oral olanzapine clinical trials as of December 31, 2001; (5) 1843 additional patients from 41 olanzapine clinical trials as of October 31, 2011.
Also included below is information from the premarketing 6-week clinical study database for olanzapine in combination with lithium or valproate, consisting of 224 patients who participated in bipolar I disorder (manic or mixed episodes) trials with approximately 22 patient-years of exposure. The conditions and duration of treatment with olanzapine varied greatly and included (in overlapping categories) open-label and double-blind phases of studies, inpatients and outpatients, fixed-dose and dose-titration studies, and short-term or longer-term exposure.
Adverse reactions were assessed by collecting adverse reactions, results of physical examinations, vital signs, weights, laboratory analytes, ECGs, chest x-rays, and results of ophthalmologic examinations. Certain portions of the discussion below relating to objective or numeric safety parameters, namely, dose-dependent adverse reactions, vital sign changes, weight gain, laboratory changes, and ECG changes are derived from studies in patients with schizophrenia and have not been duplicated for bipolar I disorder (manic or mixed episodes) or agitation.
However, this information is also generally applicable to bipolar I disorder (manic or mixed episodes) and agitation. Adverse react…
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS The risks of using olanzapine in combination with other drugs have not been extensively evaluated in systematic studies. Diazepam: May potentiate orthostatic hypotension. ( 7.1, 7.2 ) Alcohol: May potentiate orthostatic hypotension.
( 7.1 ) Carbamazepine: Increased clearance of olanzapine. ( 7.1) Fluvoxamine: May increase olanzapine levels. ( 7.1 ) Olanzapine and Fluoxetine in Combination: Also refer to the DrugInteractions section of the package insert for Symbyax.
(7.1) CNS Acting Drugs: Caution should be used when taken in combination with other centrally acting drugs and alcohol. ( 7.2 ) Antihypertensive Agents: Enhanced antihypertensive effect. ( 7.2 ) Levodopa and Dopamine Agonists: May antagonize levodopa/dopamine agonists.
(7.2 ) Other Concomitant Drug Therapy: When using olanzapine in combination with lithium or valproate, refer to the Drug Interactions sections of the package insert for those products. ( 7.2 )
7.1Potential for Other Drugs to Affect Olanzapine Diazepam — The co-administration of diazepam with olanzapine potentiated the orthostatic hypotension observed with olanzapine [see Drug Interactions (7.2) ]. Cimetidine and Antacids — Single doses of cimetidine (800 mg) or aluminum- and magnesium-containing antacids did not affect the oral bioavailability of olanzapine. Inducers of CYP1A2 — Carbamazepine therapy (200 mg bid) causes an approximately 50% increase in the clearance of olanzapine.
This increase is likely due to the fact that carbamazepine is a potent inducer of CYP1A2 activity. Higher daily doses of carbamazepine may cause an even greater increase in olanzapine clearance. Alcohol — Ethanol (45 mg/70 kg single dose) did not have an effect on olanzapine pharmacokinetics.
The co-administration of alcohol (i.e., ethanol) with olanzapine potentiated the orthostatic hypotension observed with olanzapine [see Drug Interactions (7.2) ]. Inhibitors of CYP1A2 Fluvoxamine : Fluvoxamine, a CYP1A2 inhibitor, decreases the clearance of olanzapine. This results in a mean increase in olanzapine Cmax following fluvoxamine of 54% in female nonsmokers and 77% in male smokers.
The mean increase in olanzapine AUC is 52% and 108%, respectively. Lower doses of olanzapine should be considered in patients receiving concomitant treatment with fluvoxamine. Inhibitors of CYP2D6 Fluoxetine : Fluoxetine (60 mg single dose or 60 mg daily dose for 8 days) causes a small (mean 16%) increase in the maximum concentration of olanzapine and a small (mean 16%) decrease in olanzapine clearance.
The magnitude of the impact of this factor is small in comparison to the overall variability between individuals, and therefore dose modification is not routinely recommended. When using olanzapine and fluoxetine in combination, also refer to the Drug Interactions section of the package insert for Symbyax. Warfarin — Warfarin (20 mg single dose) did not affect olanzapine pharmacokinetics [see Drug Interactions (7.2 ) ].
Inducers of CYP1A2 or Glucuronyl Transferase — Omeprazole and rifampin, may cause an increase in olanzapine clearance. Charcoal — The administration of activated charcoal (1 g) reduced the Cmax and AUC of oral olanzapine by about 60%. As peak olanzapine levels are not typically obtained until about 6 hours after dosing, charcoal may be a useful treatment for olanzapine overdose.
Anticholinergic Drugs — Concomitant treatment with olanzapine and other drugs with anticholinergic activity can increase the risk for severe gastrointestinal adverse reactions related to hypomotility. Olanzapine should be used with caution in patients receiving medications having anticholinergic (antimuscarinic) effects [see Warnings and Precautions ( 5.14 )].
7.2Potential for Olanzapine to Affect Other Drugs CNS Acting Drugs — Given the primary CNS effects of olanzapine, caution should be used when olanzapine is taken in combination with other centrally acting drugs and alcohol. Antihypertensive Agents — Olanzapine, because of its poten…

Healthcare providers are encouraged to register patients by contacting the National Pregnancy Registry for Atypical Antipsychotics at 1-866-961-2388 or visit http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/. Risk Summary Neonates exposed to antipsychotic drugs, including olanzapine, during the third trimester are at risk for extrapyramidal and/or withdrawal symptoms following delivery ( see Clinical Considerations ).
Overall available data from published epidemiologic studies of pregnant women exposed to olanzapine have not established a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes ( see Data ). There are risks to the mother associated with untreated schizophrenia or bipolar I disorder and with exposure to antipsychotics, including olanzapine, during pregnancy ( see Clinical Considerations ). Olanzapine was not teratogenic when administered orally to pregnant rats and rabbits at doses that are 9- and 30-times the daily oral maximum recommended human dose (MRHD), based on mg/m 2 body surface area; some fetal toxicities were observed at these doses ( see Data ).
The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defects, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Clinical Considerations Disease-associated maternal and embryo/fetal risk There is a risk to the mother from untreated schizophrenia or bipolar I disorder, including increased risk of relapse, hospitalization, and suicide. Schizophrenia and bipolar I disorder are associated with increased adverse perinatal outcomes, including preterm birth. It is not known if this is a direct result of the illness or other comorbid factors.
Fetal/Neonatal adverse reactions Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder have been reported in neonates who were exposed to antipsychotic drugs, including olanzapine, during the third trimester of pregnancy. These symptoms have varied in severity. Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately.
Some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization. Data Human Data Placental passage has been reported in published study reports; however, the placental passage ratio was highly variable ranging between 7% to 167% at birth following exposure during pregnancy. The clinical relevance of this finding is unknown.
Published data from observational studies, birth registries, and case reports that have evaluated the use of atypical antipsychotics during pregnancy do not establish an increased risk of major birth defects. A retrospective cohort study from a Medicaid database of 9258 women exposed to antipsychotics during pregnancy did not indicate an overall increased risk for major birth defects.

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of oral olanzapine in the treatment of schizophrenia and manic or mixed episodes associated with bipolar I disorder were established in short-term studies in adolescents (ages 13 to 17 years). Use of olanzapine in adolescents is supported by evidence from adequate and well-controlled studies of olanzapine in which 268 adolescents received olanzapine in a range of 2.5 to 20 mg/day [see Clinical Studies ( 14.1 , 14.2 ) ]. Recommended starting dose for adolescents is lower than that for adults [see Dosage and Administration ( 2.1 , 2.2 ) ].
Compared to patients from adult clinical trials, adolescents were likely to gain more weight, experience increased sedation, and have greater increases in total cholesterol, triglycerides, LDL cholesterol, prolactin and hepatic aminotransferase levels [see Warnings and Precautions ( 5 .5 , 5.15 , 5.17 ) and Adverse Reactions (6.1) ]. When deciding among the alternative treatments available for adolescents, clinicians should consider the increased potential (in adolescents as compared with adults) for weight gain and dyslipidemia.
Clinicians should consider the potential long-term risks when prescribing to adolescents, and in many cases this may lead them to consider prescribing other drugs first in adolescents [see Indications and Usage ( 1.1 , 1.2 ) ]. Safety and effectiveness of olanzapine in children <13 years of age have not been established [see Patient Counseling Information ( 17 ) ]. Safety and efficacy of olanzapine and fluoxetine in combination in children and adolescents (10 to 17 years of age) have been established for the acute treatment of depressive episodes associated with bipolar I disorder.
Safety and effectiveness of olanzapine and fluoxetine in combination in children <10 years of age have not been established.
🧓 Geriatric Use ▾
8.5Geriatric Use Of the 2500 patients in premarketing clinical studies with oral olanzapine, 11% (263) were 65 years of age or over. In patients with schizophrenia, there was no indication of any different tolerability of olanzapine in the elderly compared to younger patients. Studies in elderly patients with dementia-related psychosis have suggested that there may be a different tolerability profile in this population compared to younger patients with schizophrenia.
Elderly patients with dementia-related psychosis treated with olanzapine are at an increased risk of death compared to placebo. In placebo-controlled studies of olanzapine in elderly patients with dementia-related psychosis, there was a higher incidence of cerebrovascular adverse events (e.g., stroke, transient ischemic attack) in patients treated with olanzapine compared to patients treated with placebo. In 5 placebo-controlled studies of olanzapine in elderly patients with dementia-related psychosis (n=1184), the following adverse reactions were reported in olanzapine-treated patients at an incidence of at least 2% and significantly greater than placebo-treated patients: falls, somnolence, peripheral edema, abnormal gait, urinary incontinence, lethargy, increased weight, asthenia, pyrexia, pneumonia, dry mouth and visual hallucinations.
The rate of discontinuation due to adverse reactions was greater with olanzapine than placebo (13% vs 7%). Elderly patients with dementia-related psychosis treated with olanzapine are at an increased risk of death compared to placebo. Olanzapine is not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning , Warnings and Precautions ( 5.1 ), and Patient Counseling Information ( 17 )].
Olanzapine is not approved for the treatment of patients with dementia-related psychosis. Also, the presence of factors that might decrease pharmacokinetic clearance or increase the pharmacodynamic response to olanzapine should lead to consideration of a lower starting dose for any geriatric patient [see Boxed Warning, Dosage and Administration ( 2.1 ), and Warnings and Precautions ( 5.1 )]. Clinical studies of olanzapine and fluoxetine in combination did not include sufficient numbers of patients ≥65 years of age to determine whether they respond differently from younger patients.
🆘 Overdosage ▾
10 OVERDOSAGE
10.1Human Experience In premarketing trials involving more than 3100 patients and/or normal subjects, accidental or intentional acute overdosage of olanzapine was identified in 67 patients. In the patient taking the largest identified amount, 300 mg, the only symptoms reported were drowsiness and slurred speech. In the limited number of patients who were evaluated in hospitals, including the patient taking 300 mg, there were no observations indicating an adverse change in laboratory analytes or ECG.
Vital signs were usually within normal limits following overdoses. In postmarketing reports of overdose with olanzapine alone, symptoms have been reported in the majority of cases. In symptomatic patients, symptoms with ≥10 % incidence included agitation/aggressiveness dysarthria, tachycardia, various extrapyramidal symptoms, and reduced level of consciousness ranging from sedation to coma.
Among less commonly reported symptoms were the following potentially medically serious reactions: aspiration, cardiopulmonary arrest, cardiac arrhythmias (such as supraventricular tachycardia and 1 patient experiencing sinus pause with spontaneous resumption of normal rhythm), delirium, possible neuroleptic malignant syndrome, respiratory depression/arrest, convulsion, hypertension, and hypotension. Reports of fatality in association with overdose of olanzapine alone have been received . In 1 case of death, the amount of acutely ingested olanzapine was reported to be possibly as low as 450 mg of oral olanzapine; however, in another case, a patient was reported to survive an acute olanzapine ingestion of approximately 2 g of oral olanzapine.
10.2Management of Overdose There is no specific antidote to an overdose of olanzapine. The possibility of multiple drug involvement should be considered. Establish and maintain an airway and ensure adequate oxygenation and ventilation.
Cardiovascular monitoring should commence immediately and should include continuous electrocardiographic monitoring to detect possible arrhythmias. Contact a Certified Poison Control Center for the most up to date information on the management of overdosage (1-800-222- 1222). For specific information about overdosage with lithium or valproate, refer to the Overdosage section of the prescribing information for those products.
For specific information about overdosage with olanzapine and fluoxetine in combination, refer to the Overdosage section of the Symbyax prescribing information.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action The mechanism of action of olanzapine, in the listed indications is unclear. However, the efficacy of olanzapine in schizophrenia could be mediated through a combination of dopamine and serotonin type 2 (5HT 2 ) antagonism.
12.2Pharmacodynamics Olanzapine binds with high affinity to the following receptors: serotonin 5HT 2A/2C , 5HT 6 (K i =4, 11, and 5 nM, respectively), dopamine D 1-4 (K i =11-31 nM), histamine H 1 (K i =7 nM), and adrenergic α 1 receptors (K i =19 nM). Olanzapine is an antagonist with moderate affinity binding for serotonin 5HT 3 (K i =57 nM) and muscarinic M 1-5 (K i =73, 96, 132, 32, and 48 nM, respectively). Olanzapine binds with low affinity to GABA A , BZD, and β adrenergic receptors (K i >10 μM).
12.3Pharmacokinetics Oral Administration, Monotherapy — Olanzapine is well absorbed and reaches peak concentrations in approximately 6 hours following an oral dose. It is eliminated extensively by first pass metabolism, with approximately 40% of the dose metabolized before reaching the systemic circulation. Food does not affect the rate or extent of olanzapine absorption.
Pharmacokinetic studies showed that olanzapine tablets and olanzapine orally disintegrating tablets dosage forms of olanzapine are bioequivalent. Olanzapine displays linear kinetics over the clinical dosing range. Its half-life ranges from 21 to 54 hours (5th to 95th percentile; mean of 30 hr), and apparent plasma clearance ranges from 12 to 47 L/hr (5th to 95th percentile; mean of 25 L/hr).
Administration of olanzapine once daily leads to steady-state concentrations in about 1 week that are approximately twice the concentrations after single doses. Plasma concentrations, half-life, and clearance of olanzapine may vary between individuals on the basis of smoking status, gender, and age. Olanzapine is extensively distributed throughout the body, with a volume of distribution of approximately 1000 L.
It is 93% bound to plasma proteins over the concentration range of 7 to 1100 ng/mL, binding primarily to albumin and α 1 -acid glycoprotein. Metabolism and Elimination — Following a single oral dose of 14 C labeled olanzapine, 7% of the dose of olanzapine was recovered in the urine as unchanged drug, indicating that olanzapine is highly metabolized. Approximately 57% and 30% of the dose was recovered in the urine and feces, respectively.
In the plasma, olanzapine accounted for only 12% of the AUC for total radioactivity, indicating significant exposure to metabolites. After multiple dosing, the major circulating metabolites were the 10-N-glucuronide, present at steady state at 44% of the concentration of olanzapine, and 4´-N-desmethyl olanzapine, present at steady state at 31% of the concentration of olanzapine. Both metabolites lack pharmacological activity at the concentrations observed.
Direct glucuronidation and cytochrome P450 (CYP) mediated oxidation are the primary metabolic pathways for olanzapine. In vitro studies suggest that CYPs 1A2 and 2D6, and the flavin-containing monooxygenase system are involved in olanzapine oxidation. CYP2D6 mediated oxidation appears to be a minor metabolic pathway in vivo , because the clearance of olanzapine is not reduced in subjects who are deficient in this enzyme.
Specific Populations Renal Impairment — Because olanzapine is highly metabolized before excretion and only 7% of the drug is excreted unchanged, renal dysfunction alone is unlikely to have a major impact on the pharmacokinetics of olanzapine. The pharmacokinetic characteristics of olanzapine were similar in patients with severe renal impairment and normal subjects, indicating that dosage adjustment based upon the degree of renal impairment is not required. In addition, olanzapine is not removed by dialysis.
The effect of renal impairment on metabolite elimination has not been studied. Hepatic Impairment — Although the presence of hepatic impairment may be expected to reduce the clearance of ola…

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Medication Guide) for the oral formulations. Patients should be advised of the following issues and asked to alert their prescriber if these occur while taking olanzapine as monotherapy or in combination with fluoxetine. If you do not think you are getting better or have any concerns about your condition while taking olanzapine, call your doctor.
When using olanzapine and fluoxetine in combination, also refer to the Patient Counseling Information section of the package insert for Symbyax. Elderly Patients with Dementia-Related Psychosis: Increased Mortality and Cerebrovascular Adverse Events (CVAE), Including Stroke Patients and caregivers should be advised that elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Patients and caregivers should be advised that elderly patients with dementia-related psychosis treated with olanzapine had a significantly higher incidence of cerebrovascular adverse events (e.g., stroke, transient ischemic attack) compared with placebo.
Olanzapine is not approved for elderly patients with dementia-related psychosis [see Boxed Warning and Warnings and Precautions ( 5.1 ) ]. Neuroleptic Malignant Syndrome (NMS) Patients and caregivers should be counseled that a potentially fatal symptom complex sometimes referred to as NMS has been reported in association with administration of antipsychotic drugs, including olanzapine. Signs and symptoms of NMS include hyperpyrexia, muscle rigidity, altered mental status, and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmia) [see Warnings and Precautions ( 5.3 ) ].
Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) Patients should be advised to report to their health care provider at the earliest onset of any signs and symptoms that may be associated with drug reaction with eosinophilia and systemic symptoms (DRESS) [see Warnings and Precautions ( 5.4 ) ]. Hyperglycemia and Diabetes Mellitus Patients should be advised of the potential risk of hyperglycemia-related adverse reactions. Patients should be monitored regularly for worsening of glucose control.
Patients who have diabetes should follow their doctor’s instructions about how often to check their blood sugar while taking olanzapine [see Warnings and Precautions ( 5.5 ) ]. Dyslipidemia Patients should be counseled that dyslipidemia has occurred during treatment with olanzapine. Patients should have their lipid profile monitored regularly [see Warnings and Precautions ( 5.5 ) ].
Weight Gain Patients should be counseled that weight gain has occurred during treatment with olanzapine. Patients should have their weight monitored regularly [see Warnings and Precautions ( 5.5 ) ]. Orthostatic Hypotension Patients should be advised of the risk of orthostatic hypotension, especially during the period of initial dose titration and in association with the use of concomitant drugs that may potentiate the orthostatic effect of olanzapine, e.g., diazepam or alcohol [see Warnings and Precautions (5.7) and Drug Interactions ( 7 ) ].
Patients should be advised to change positions carefully to help prevent orthostatic hypotension, and to lie down if they feel dizzy or faint, until they feel better. Patients should be advised to call their doctor if they experience any of the following signs and symptoms associated with orthostatic hypotension: dizziness, fast or slow heart beat, or fainting. Potential for Cognitive and Motor Impairment Because olanzapine has the potential to impair judgment, thinking, or motor skills, patients should be cautioned about operating hazardous machinery, including automobiles, until they are reasonably certain that olanzapine therapy does not affect them adversely [see Warnings and Precautions ( 5.12 ) ].

There may be new information. This Medication Guide does not take the place of talking to your doctor about your medical condition or treatment.
Talk with your doctor or pharmacist if there is something you do not understand or you want to learn more about olanzapine orally disintegrating tablets. What is the most important information I should know about olanzapine orally disintegrating tablets? Olanzapine orally disintegrating tablets may cause serious side effects, including: 1.
Increased risk of death in elderly people who are confused, have memory loss and have lost touch with reality (dementia-related psychosis). 2. High blood sugar (hyperglycemia).
3. High fat levels in your blood (increased cholesterol and triglycerides), especially in teenagers age 13 to 17, or when used in combination with fluoxetine in children age 10 to 17. 4.
Weight gain, especially in teenagers age 13 to 17, or when used in combination with fluoxetine in children age 10 to 17. These serious side effects are described below. 1.
Increased risk of death in elderly people who are confused, have memory loss and have lost touch with reality (dementia-related psychosis). Olanzapine orally disintegrating tablets are not approved for treating psychosis in elderly people with dementia. 2.
High blood sugar (hyperglycemia). High blood sugar can happen if you have diabetes already or if you have never had diabetes. High blood sugar could lead to: a build up of acid in your blood due to ketones (ketoacidosis) coma death Your doctor should do tests to check your blood sugar before you start taking olanzapine orally disintegrating tablets and during treatment.
In people who do not have diabetes, sometimes high blood sugar goes away when olanzapine orally disintegrating tablets are stopped. People with diabetes and some people who did not have diabetes before taking olanzapine orally disintegrating tablets need to take medicine for high blood sugar even after they stop taking olanzapine orally disintegrating tablets. If you have diabetes, follow your doctor’s instructions about how often to check your blood sugar while taking olanzapine orally disintegrating tablets.
Call your doctor if you have any of these symptoms of high blood sugar (hyperglycemia) while taking olanzapine orally disintegrating tablets: feel very thirsty need to urinate more than usual feel very hungry feel weak or tired feel sick to your stomach feel confused or your breath smells fruity 3. High fat levels in your blood (cholesterol and triglycerides). High fat levels may happen in people treated with olanzapine orally disintegrating tablets, especially in teenagers (13 to 17 years old), or when used in combination with fluoxetine in children (10 to 17 years old).
You may not have any symptoms, so your doctor should do blood tests to check your cholesterol and triglyceride levels before you start taking olanzapine orally disintegrating tablets and during treatment. 4. Weight gain.
Weight gain is very common in people who take olanzapine orally disintegrating tablets. Teenagers (13 to 17 years old) are more likely to gain weight and to gain more weight than adults. Children (10 to 17 years old) are also more likely to gain weight and to gain more weight than adults when olanzapine is used in combination with fluoxetine.
Some people may gain a lot of weight while taking olanzapine orally disintegrating tablets, so you and your doctor should check your weight regularly. Talk to your doctor about ways to control weight gain, such as eating a healthy, balanced diet, and exercising. What are olanzapine orally disintegrating tablets?
