Who makes letrozole?

Who manufactures letrozole tablets and generics?

Letrozole is sold as a medicine under brand names including Femara. Different companies manufacture the drug substance and sell finished letrozole products, but the market is largely driven by multiple generic manufacturers that produce tablets after regulatory approval.

How to check the exact manufacturer for the letrozole you have

The manufacturer can vary by country, pharmacy, and the specific product strength (for example, 2.5 mg tablets). To confirm who makes your particular dose, check the label for:
- Brand name (if any)
- Strength (e.g., 2.5 mg)
- “Manufactured for by” / “Distributed by” details on the package insert or bottle
