- **4.2 Posology and method of administration**
Schizophrenia
The recommended starting dose for olanzapine is 10 mg/day.
Manic episode
The starting dose is 15mg as a single daily dose in monotherapy or 10mg daily in combination therapy (see section 5.1 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_).
Preventing recurrence in bipolar disorder
The recommended starting dose is 10 mg/day. For patients who have been receiving olanzapine for treatment of manic episode, continue therapy for preventing recurrence at the same dose. If a new manic, mixed or depressive episode occurs, olanzapine treatment should be continued (with dose optimisation as needed), with supplementary therapy to treat mood symptoms, as clinically indicated.
During treatment for schizophrenia, manic episode and recurrence prevention in bipolar disorder, daily dosage may subsequently be adjusted on the basis of individual clinical status within the range 5–20 mg/day. An increase to a dose greater than the recommended starting dose is advised only after appropriate clinical reassessment and should generally occur at intervals of not less than 24 hours. Olanzapine can be given without regards for meals as absorption is not affected by food. Gradual tapering of the dose should be considered when discontinuing olanzapine.
Method of administration
Olanzapine orodispersible tablet should be placed in the mouth, where it will rapidly disperse in saliva, so it can be easily swallowed. Removal of the intact orodispersible tablet from the mouth is difficult. Since the orodispersible tablet is fragile, it should be taken immediately on opening the blister. Alternatively, it may be dispersed in a full glass of water or other suitable beverage (orange juice, apple juice, milk or coffee) immediately before administration.
Olanzapine orodispersible tablet is bioequivalent to olanzapine tablets, with a similar rate and extent of absorption. It has the same dosage and frequency of administration as olanzapine tablets. Olanzapine orodispersible tablets may be used as an alternative to olanzapine tablets.
Elderly
A lower starting dose (5 mg/day) is not routinely indicated but should be considered for those 65 and over when clinical factors warrant (see section 4.4 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_).
Renal and/or hepatic impairment
A lower starting dose (5mg) should be considered for such patients. In cases of moderate hepatic insufficiency (cirrhosis, Child-Pugh Class A or B), the starting dose should be 5mg and only increased with caution.
Smokers
The starting dose and dose range need not be routinely altered for non-smokers relative to smokers. The metabolism of olanzapine may be induced by smoking. Clinical monitoring is recommended and an increase of olanzapine dose may be considered if necessary (see section 4.5 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_).
When more than one factor is present which might result in slower metabolism (female gender, geriatric age, non-smoking status), consideration should be given to decreasing the starting dose. Dose escalation, when indicated, should be conservative in such patients (see sections 4.5 and 5.2 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_).
Paediatric population
Olanzapine is not recommended for use in children and adolescents below 18 years of age due to a lack of data on safety and efficacy. A greater magnitude of weight gain, lipid and prolactin alterations has been reported in short-term studies of adolescent patients than in studies of adult patients (see sections 4.4, 4.8, 5.1 and 5.2 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_).

- Indication Info
- **4.1 Therapeutic indications**
Olanzapine is indicated for the acute and maintenance treatment of schizophrenia and other psychoses where positive symptoms (e.g. delusions, hallucinations, disordered thinking, hostility, suspiciousness) and/or negative symptoms (e.g. flattened affect, emotional and social withdrawal, poverty of speech) are prominent. Olanzapine also alleviates the secondary affective symptoms commonly associated with schizophrenia and related disorders.
Olanzapine is effective in maintaining the clinical improvement during continuation therapy in patients who have shown an initial treatment response.
Olanzapine is indicated for short-term treatment of acute manic episode associated with bipolar I disorder.
Olanzapine is indicated for preventing recurrence of manic, mixed or depressive episodes in bipolar I disorder.
