What is Letrozole 

Letrozole  is a powerful Aromatase Inhibitor that was developed to fight breast cancer. For athletes and bodybuilders, it is a drug used to combat the estrogenic side effects of anabolic steroids water-retention, acne and gynocomastia. It will also raise testosterone levels because of the lowered estrogen in the body. Side effects from include a lowered sex drive and continuous use can lead to lowered lipid function and an impaired immune system. 

How Letrozole works

Letrozole lowers the levels of the female sex hormone oestrogen in the body. Oestrogen stimulates some breast cancers to grow. These breast cancers are called hormone sensitive or hormone receptor positive. Femara can stop or slow the growth of these cancers. It can also reduce the chance of a breast cancer coming back after surgery.


Letrozole only works in women who have had their menopause. It is a type of drug called an aromatase inhibitor. After the menopause, women don't produce oestrogen from their ovaries. But they still produce a small amount by using an enzyme called aromatase which turns other sex hormones called androgens into oestrogen. This change happens mainly in fatty tissue, muscle and the skin. Aromatase inhibitors block aromatase so that it can't change the androgen into oestrogen.


Letrozole Dosage and half life

The half life is approximately 2-4 days. 

Femara comes in tablets of 2.5 milligrams (mg).

How much Letrozole your doctor tells you to take may vary, but for cancer, a usual dose is 2.5 mg a day. 

If you're taking Femara for fertility treatment, your doctor may tell you to take either 2.5 mg or 5 mg of the drug, beginning on the third day of your period for five days.
