Description


Indications

Femara (Letrozole) is a medication used to treat breast cancer in postmenopausal women. Its drug belongs to the aromatase inhibitor class. Femara works by blocking the enzyme aromatase, which is responsible for converting testosterone into estrogen. By blocking aromatase, Femara reduces the amount of estrogen in the body and can help slow the growth of some types of breast cancer.

Femara is an effective and commonly used treatment for breast cancer patients. However, it can be used for off-label drug as a fertility treatment for women with ovulation problems, or for those with unexplained infertility. In addition, letrozole is indicated for adjuvant treatment of early breast cancer, extended adjuvant treatment of early breast cancer, and first and second-line treatment of advanced breast cancer.

Letrozole comes as a tablet to take by mouth once a day with or without food. Take letrozole at around the same time every day and follow the directions on your prescription label carefully. Do not take more or less of it or take it more often than prescribed by your doctor.

The recommended dose of femara is one 2.5 mg tablet administered once a day, without regard to meals. Use in adjuvant treatment of early breast cancer. In the adjuvant setting, femara is used for a period of 5 years. For extended adjuvant treatment of early breast cancer, the recommended dose is also 2.5 mg once a day.
