This medication is used to treat certain types of breast
cancer (such as hormone-receptor-positive breast cancer) in women after
menopause. Exemestane is also used to help prevent the cancer from
returning. Some breast cancers are made to grow faster by a natural hormone
called estrogen. Exemestane decreases the amount of estrogen the body makes
and helps to slow or reverse the growth of these breast
cancers.
Exemestane is usually not used in women of childbearing
age.
Read the Patient Information Leaflet if available from
your pharmacist before you start using exemestane and each time you get a
refill. If you have any questions, ask your doctor or
pharmacist.
