The brand name for letrozole is femara. It is a drug that is usually used to treat post-menopausal breast cancer, but can be used in a similar way to clomid. I take 2 tablets for days 4-8 of my cycle.
From memory, clomid stops the body from seeing the estrogen that is there, and then fools the body into ovulating. Letrozole stops the body from making estrogen, it uses a different mechanism in the body to achieve the same outcome. I have more information on it at home - I'll type some up for you when I get home from acupuncture tonight.
