Femara (Letrozole) is an oral drug which can be an effective fertility treatment for women with ovulation problems, or for those with unexplained infertility. This medication is in a class of drug called aromatase inhibitors. Femara has mainly been used to treat certain cases of breast cancer.
Femara 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.
