What are the most common brand names for letrozole?
Letrozole is an oral aromatase inhibitor used for hormone receptor–positive breast cancer in postmenopausal patients, and brand names vary by country and manufacturer. In the U.S., the best-known brand name for letrozole is:
- Femara (letrozole)
Are there other brand names besides Femara?
Yes. Outside the U.S., letrozole may be marketed under different brand names, and many countries also use locally marketed products even when the active ingredient is the same. If you tell me your country (or where you bought the prescription), I can narrow the list to brands used there.
What does “letrozole” look like on a prescription or label?
On many prescriptions, the drug may appear as:
- “Letrozole” (generic name), or
- “Femara” (brand name), especially in regions where that brand is commonly used.
Can brand names differ from country to country?
Yes. Marketing authorizations are country-specific, so the same active ingredient (letrozole) can have different brand names depending on the regulator and manufacturer in that market.
What about generics and how are they labeled?
In many places, letrozole is available as generics labeled with the generic name “letrozole” followed by the manufacturer name, such as “letrozole tablets” (no brand name) on the bottle. In those cases, the active ingredient is still letrozole even if the brand differs.
If you share your country (and the strength, like 2.5 mg), I can list the likely brand names used where you are.
