Which companies make letrozole?
Several manufacturers make generic and brand forms of letrozole (an aromatase inhibitor used for certain types of breast cancer). Specific manufacturers vary by country and by whether you’re looking for the brand product or a generic.
How to find the exact manufacturer on a letrozole package
To identify the manufacturer for the specific product you have (or plan to buy), check:
- The label for the company name (often listed as “Manufactured by” or “Marketed by”).
- The drug’s strength (e.g., 2.5 mg) and dosage form (tablet).
- The National Drug Code (NDC) or local equivalent (commonly tied to a single product/labeler).
Are generic letrozole tablets interchangeable between manufacturers?
In most cases, generic letrozole tablets are considered interchangeable when they meet the same approved strength, route, and dosage form. Differences can still matter for patients due to excipients, pill appearance, and how tablets are scored or packaged, so pharmacies often switch based on availability.

If you tell me your country and tablet strength, I can narrow the list
Manufacturer names can differ by market. Share:
- your country (or where you’ll buy it), and
- the tablet strength (commonly 2.5 mg),
and I can help you determine which manufacturer corresponds to the product you’re targeting.
