What is in this leaflet

This leaflet answers some common questions about EXEMESTANE PFIZER.

It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking EXEMESTANE PFIZER against the benefits it is expected to have for you.

If you have any concerns about this medicine, ask your doctor or pharmacist.

Keep this leaflet. You may need to read it again.

What EXEMESTANE PFIZER is used for

EXEMESTANE PFIZER is used to treat breast cancer in women who no longer have their menstrual periods, either naturally due to their age (after menopause) or because they have had their ovaries surgically removed.

EXEMESTANE PFIZER is used to reduce the risk of recurrence or spreading of the breast cancer. It is also used when the cancer has not responded or has returned after treatment with another medicine or medicines.


EXEMESTANE PFIZER is an aromatase inactivator. It works by significantly reducing the supply of oestrogen to cancer cells.

This stops the growth of those cancer cells which need oestrogen, a natural female sex hormone, to grow.

Ask your doctor if you have any questions about why EXEMESTANE PFIZER has been prescribed for you. Your doctor may have prescribed it for another purpose.

EXEMESTANE PFIZER is only available with a doctor’s prescription. It is not addictive.
