Detailed description:

This medication is used to treat certain types of breast cancer (such as hormone-receptor-positive breast cancer) in women after menopause. Letrozole is also used to help prevent the cancer from returning. Some breast cancers are made to grow faster by a natural hormone called estrogen. Letrozole decreases the amount of estrogen the body makes and helps to slow or reverse the growth of these breast cancers.

What is Femara?

Femara (letrozole) lowers estrogen levels in postmenopausal women, which may slow the growth of certain types of breast tumors that need estrogen to grow in the body.

Femara is used to treat breast cancer in postmenopausal women. It is often given to women who have been taking tamoxifen (Nolvadex, Soltamox) for 5 years.

Femara may also be used for purposes not listed in this medication guide.

How to use Femara

Read the Patient Information Leaflet provided by your pharmacist before you start using letrozole and each time you get a refill. If you have any questions, consult your doctor or pharmacist.

Before taking this medicine

You should not use Femara if you are allergic to letrozole, or if you have:

• if you have not gone completely through menopause.

To make sure Femara is safe for you, tell your doctor if you have:

• liver disease (especially cirrhosis);

• osteoporosis, osteopenia (low bone mineral density);

• high cholesterol; or

• if you also take tamoxifen.

Although it is not likely that a postmenopausal woman would be pregnant, Femara could harm an unborn baby. Do not take this medicine if you are pregnant or may become pregnant. Use effective birth control if you are not past menopause,and tell your doctor right away if you become pregnant during treatment.

It is not known whether letrozole passes into breast milk or if it could harm a nursing baby. You should not breast-feed while you are using Femara.
