have there been any adverse interactions between femara (letrozole) and grapefuit?

Indirectly: There is a substance in grapefruit that disables the enzyme responsible for metabolizing estrogen in our bodies; therefore, eating grapefruit may increase the body's levels of estrogen. Femara (letrozole) is used to inhibit the production of estrogen in the body as a treatment for hormone-sensitive breast cancer. Therefore, eating grapefruit in these circumstances may counteract what you are treating.

Yes.: Tamoxifen is a selective estrogen receptor modulator; Letrozole is an aromatase inhibitor. Both drugs are used to treat hormone-positive breast cancer patients. However, Letrozole can only be used after menopause. Furthermore, tamoxifen can also be used to prevent breast cancer in high-risk women.

See full answer: Currently the alternatives to Femara (also known as letrozole) are Arimidex (anastrozole) and Aromasin (exemestane). All 3 belong to a class of medications known as aromatase inhibitors and can help reduce the risk of breast cancer recurrence. Another type of medication, tamoxifen, is known as a selective estrogen receptor modulator, or serm - it is primarily used in premenopapusal women.
