Effectiveness of the drug

Letrozole effectively blocks estrogen production by substituting protein components for aromatase receptors. Due to its high potency, the drug should be used with caution – carefully review the dose, frequency and duration of use. While exercising may be desirable to increase blood testosterone levels, side effects should be considered. Letrozole can cause typical manifestations of estrogen deficiency including osteoporosis, atrophy, decreased libido, erectile dysfunction and painful intercourse.
