Descriptions:

 

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.

 

OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.


This medication may also be used to treat infertility in women.


Application:

 

Femara is a non-steroidal aromatase inhibitor (lowers estrogen production) 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 is available in generic form. Common side effects of Femara include hot flashes, hair loss, joint/bone/muscle pain, tiredness, unusual sweating or night sweats, nausea, diarrhea, dizziness, trouble sleeping, drowsiness, weight gain, weakness, flushing (warmth, redness, or tingly feeling), headache, constipation, numbness/tingling/weakness/stiffness in your hand or fingers, or pain in your hand that spreads to your arm, wrist, forearm, or shoulder.
