Which companies make olanzapine?
Olanzapine is made by multiple drug manufacturers worldwide, including both brand-name and generic producers. The best way to identify the exact manufacturer for a specific product is to check the labeling on the bottle/box (it lists the “manufactured for”/“distributed by” company and sometimes the actual site).
How to find the exact manufacturer for your specific olanzapine tablet or ODT
Look for these items on your packaging:
- “Manufactured by” (or “Manufactured for”) the company name
- NDC number (US) and then match that NDC to a manufacturer through the label or pharmacy records
- Lot number and imprint code (often printed on the tablet)
These details matter because different manufacturers can make olanzapine under the same generic name.
Generic olanzapine: why the manufacturer can differ
Even when you’re prescribed “olanzapine,” the pill strength and dosage form (tablet vs. orally disintegrating tablet) can be produced by different generic companies. Pharmacies may switch suppliers over time based on availability and contracts.
Brand-name olanzapine vs generics
If you have a brand product (not the generic), the label will show the brand’s marketing/distribution company. If you have a generic, the label typically shows the generic manufacturer instead.
Can you switch manufacturers without changing the dose?
In most cases, switching between generic manufacturers does not change the prescribed dose, but it can affect the specific formulation details (like excipients), which may matter for some patients. If you notice new side effects or lack of effect after a switch, confirm the manufacturer/NDC with your pharmacist.
