What Femara is and how it works

People aged 65 years and over can use this medicine at the
same dose as for other adults.

Other medicines and Femara
Tell your doctor or pharmacist if you are taking, have recently
taken or might take any other medicines, including medicines
obtained without a prescription.

Pregnancy, breast-feeding and fertility

You should only take Femara when you have gone
through the menopause. However, your doctor should
discuss with you the use of effective contraception, as you
may still have the potential to become pregnant during
treatment with Femara.
You must not take Femara if you are pregnant or breast
feeding as it may harm your baby.

Driving and using machines
If you feel dizzy, tired, drowsy or generally unwell, do not drive
or operate any tools or machines until you feel normal again.

Femara contains lactose
Femara contains lactose (milk sugar). If you have been told by
your doctor that you have an intolerance to some sugars,
contact your doctor before taking this medicine.

Femara 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.


Femara 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.

Taking Femara at the same time each day will help you
remember when to take your tablet.

What Femara is used for
Femara 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.

How long to take Femara

Femara 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 Femara works or why this
medicine has been prescribed for you, ask your doctor.

Follow all the doctor’s instructions carefully.
They may differ from the general information in this leaflet.

Do not take Femara

if you are allergic to letrozole or to any of the other
ingredients of this medicine (listed in section 6),
if you still have periods, i.e. if you have not yet gone
through the menopause,
if you are pregnant,
if you are breast-feeding.

If any of these conditions apply to you, do not take this
medicine and talk to your doctor.
