Letrozole is a medication that belongs to a class of drugs known as aromatase inhibitors. It is commonly used in the treatment of breast cancer, particularly in postmenopausal women whose cancer is hormone receptor-positive.

New Study Suggests Lower Dosage of Letrozole May be Effective for Breast Cancer Treatment

Aromatase inhibitors work by blocking the enzyme aromatase, which is responsible for converting androgens (male hormones) into estrogen (female hormones) in the body. By inhibiting this process, letrozole helps to lower estrogen levels in the body, which can slow or stop the growth of hormone receptor-positive breast cancer cells.

Aside from its use in breast cancer treatment, letrozole is also sometimes prescribed off-label for other conditions such as infertility in women with polycystic ovary syndrome (PCOS). In this case, letrozole is used to help stimulate ovulation by indirectly increasing levels of follicle-stimulating hormone (FSH), which can improve the chances of successful pregnancy.

Like all medications, letrozole can have side effects, which may include hot flashes, fatigue, nausea, bone thinning, and joint pain. It is important to discuss any concerns or potential side effects with a healthcare provider before starting treatment with letrozole.
