1). The anti-estrogen action of Femara has been shown to be useful in pretreatment for termination of pregnancy, in combination with misoprostol. It can be used in place of mifepristone, which is expensive and unavailable in many countries.
2). Femara has been used for ovarian stimulation by fertility doctors since 2001 because it has fewer side-effects than clomiphene (Clomid) and less chance of multiple gestation. A Canadian study presented at the American Society of Reproductive Medicine 2005 Conference suggested that letrozole may increase the risk of birth defects. A more detailed ovulation induction follow-up study found that Femara, compared with a control group of clomiphene, had significantly lower congenital malformations and chromosomal abnormalities at an overall rate of 2.4% (1.2% major malformations) compared with clomiphene 4.8% (3.0% major malformations).
Despite this, India banned the usage of Femara in 2011, citing potential risks to infants.In 2012, an Indian parliamentary committee said that the drug controller office colluded with letrozole's makers to approve the drug for infertility in India and also stated that Femara's use for infertility was illegal worldwide; however, such off-label uses are legal in many countries such as the US and UK.
3). Femara is sometimes used as a treatment for gynecomastia, although it is probably most effective at this if caught in an early stage (such as in users of anabolic steroids).
4). Femara has also been shown to delay the fusing of the growth plates in mice.When used in combination with growth hormone, Femara has been shown effective in one adolescent boy with a short stature.
