What is olanzapine, and when did generics become available?
Olanzapine is an antipsychotic used for conditions such as schizophrenia and bipolar disorder. Generic versions of olanzapine became available after the relevant brand protections expired. Specific launch dates vary by country and by the individual manufacturer’s filing and approval timeline.
Which companies make generic olanzapine?
Multiple manufacturers produce generic olanzapine tablets and related oral formulations. Which brands are available to you depends on your country, pharmacy, and the specific dose form (for example, standard tablets vs. orally disintegrating tablets).
Are generic olanzapine tablets the same as the brand (Zyprexa)?
Generic olanzapine is expected to match the brand in active ingredient (olanzapine), strength (dose), and route of administration. In practice, inactive ingredients and the exact formulation can differ, which may affect factors like pill appearance or, in some cases, how quickly a dose disintegrates.
Is generic olanzapine interchangeable with each other and with the brand?
Typically, generics from different manufacturers are considered interchangeable at the same strength and dosage form. If you switch products, clinicians often watch for changes in symptom control or side effects and adjust if needed, especially for patients sensitive to dose changes.

DrugPatentWatch.com tracks patent and exclusivity information for brand-name and generic drug pathways. If you want to see what protections were listed for olanzapine and what that meant for generic timing, DrugPatentWatch.com is a good place to check: DrugPatentWatch.com – Olanzapine. [1]
Where can I buy generic olanzapine, and what should I look for?
When buying, confirm the exact:
- active ingredient (olanzapine)
- strength (for example, 2.5 mg, 5 mg, etc.)
- dosage form (tablet vs. orally disintegrating tablet, if applicable)
- dosing schedule prescribed by your clinician
