What Letrozole 2.5 mg Film-Coated Tablet is
and what it is used for
What Letrozole 2.5 mg Film-Coated Tablet is and how it
Letrozole 2.5 mg Film-Coated Tablets contains an active
substance called letrozole. It belongs to a group of
medicines called aromatase inhibitors. It is a hormonal (or
"endocrine") breast cancer treatment. Growth of breast
cancer is frequently stimulated by oestrogens which are
female sex hormones. Letrozole reduces the amount of
oestrogen by blocking an enzyme (“aromatase”) involved
in the production of oestrogens and therefore may block
the growth of breast cancer that needs oestrogens to
grow. As a consequence tumour cells slow or stop
growing and/or spreading to other parts of the body.
What Letrozole is used for
Letrozole is used to treat breast cancer in women who
have gone through menopause i.e. cessation of periods.
It is used to prevent cancer from happening again. It can
be used as first treatment before breast cancer surgery in
case immediate surgery is not suitable or it can be used as
first treatment after breast cancer surgery or following five
years treatment with tamixofen. Letrozole is also used to
prevent breast tumour spreading to other parts of the
body in patients with advanced breast cancer.
If you have any questions about how Letrozole works or
why this medicine has been prescribed for you, ask your
