Femar – Letrozole uses, dose, and side effects

}

2.5 mg film-coated tablets 
letrozole

1. What Femar is and what it is used for

What Femar is and how it works

Femar contains an active substance called letrozole. It belongs to a group of medicines called aromatase inhibitors. It is a hormonal (or “endocrine”) treatment for breast cancer. The growth of breast tumors is often stimulated by the female sex hormone estrogen. Femar reduces the amount of estrogen by blocking an enzyme(“aromatase”) that participates in the production of estrogen and can therefore stop the growth of breast tumors that need estrogen to grow. This slows or stops the growth of tumor cells and their spread to other parts of the body.

What Femar is used for

Femar is used to treat breast cancer in women who have undergone menopause, ie. no longer have menstruation.

It is used to prevent the recurrence of cancer. It can be used as the first treatment before breast surgery when immediate surgery is not appropriate, or as the first treatment after breast surgery or after five years of treatment with tamoxifen. Femar is also used to prevent breast tumors from spreading to other parts of the body in patients with advanced breast cancer.

Ask your doctor if you are wondering how Femar works or why you have been prescribed it.
