Product Information: Femara

Product Information
A potent aromatase inhibitor.

Femara® is the best known brand of a drug called Letrozole.

This is a potent and selective non-steroidal inhibitor of the Aromatase (estrogen synthetase) system, which converts testosterone and adrenal androgens to estrogens in peripheral tissue.

Femara is used in the treatment of advanced or locally advanced breast cancer, and as adjuvant treatment in early breast cancer. In postmenopausal women the dose is often 2.5mg daily by mouth.

However, Femara is also used by "aging" men, who want to reduce their conversion of testosterone and adrenal hormones to estrogens. This is because it is quite common for a 59-year old man to have more estrogen circulating (primarily as estradiol), than a 54-year old woman!

It is thus believed that "skewed" estrogen ratios, possibly caused by toxins, environmental factors and aging, play a major role in the formation of cancers in both men and women, (particularly prostate, cervical and breast), and also lead to other disturbances such as increased fat deposits etc.

Your estradiol, estrone and testosterone levels can be monitored using the saliva test kit.

Although it's an unofficial use, an average of 1.25mg Femara, once or twice per week is used by men who wish to see their estrogen levels decline, and their free testosterone levels increase.
