                        Pregnancy-Lactation
Pregnancy
Based on post-marketing reports, findings from animal studies and mechanism of action, therapy can cause fetal harm and is contraindicated for use in pregnant women; in post-marketing reports, use during pregnancy resulted in cases of spontaneous abortions and congenital birth defects; however, data are insufficient to inform a drug-associated risk
Contraception
Advise females of reproductive potential to use effective contraception during treatment and for at least 3 weeks after last dose
Infertility
Therapy may impair fertility in females and males of reproductive potential
Lactation
Not known if therapy is present in human milk; there are no data on effects on breastfed infant or milk production; exposure of lactating rats to drug was associated with impaired reproductive performance of male offspring; because of potential for serious adverse reactions in breastfed infants, advise lactating women not to breastfeed while receiving therapy and for at least 3 weeks after last dose

                        Mechanism of Action
Letrozole competitively binds to the heme group of aromatase, a cytochrome P450 enzyme which catalyzes conversion of androgen to oestrogen, leading to inhibition of the enzyme and a significant reduction in plasma oestrogen levels.
