Letrozole Indications for Use

Letrozole is a medication commonly used in the treatment of breast cancer. It belongs to a class of drugs known as aromatase inhibitors, which work by decreasing the amount of estrogen produced in the body. Letrozole is primarily indicated for use in postmenopausal women with hormone receptor-positive breast cancer.

Primary Indication

The primary indication for letrozole is to treat hormone receptor-positive breast cancer in postmenopausal women. This type of breast cancer relies on estrogen to grow and spread. By inhibiting the production of estrogen in the body, letrozole helps to slow down or stop the growth of cancer cells.

Adjuvant Therapy

Letrozole may also be used as adjuvant therapy following surgery or radiation in postmenopausal women with early-stage breast cancer. Adjuvant therapy aims to reduce the risk of cancer recurrence by targeting any remaining cancer cells that may not have been removed during initial treatment.

Off-Label Uses

While letrozole is primarily indicated for breast cancer, it may also be prescribed off-label for other conditions such Letrozol Winthrop 2,5 mg as infertility in women. In these cases, letrozole is used to induce ovulation by stimulating the release of eggs from the ovaries.


Letrozole is a valuable medication with several indications for use, particularly in the treatment of hormone receptor-positive breast cancer in postmenopausal women. It is important to follow your healthcare provider’s instructions when taking letrozole to ensure its effectiveness and minimize potential side effects.
