Very helpful: Femara or Letrozole is an oral ovulation induction medication. It works sometimes when Clomid (clomiphene) doesn't. It also helps pregnancies to occur when Clomid (clomiphene) fails. It seems to be very helpful especially in patients with pcos. The pregnancy rates are similar to Clomid (clomiphene) but the side effects are less and the multiple pregnancies seem to be also less. ...Read more

Will anything (OTC medicines, herbs, supplements etc) decrease the effectiveness of taking femara (letrozole) for infertility?
Yes: Letrozole (femara) is primarily cleared/metabolized by a liver enzyme called cytochrome p450. Several herbs and supplements can enhance or impair cytochrome p450 activity and hence alter the metabolism of letrazole through competing at this enzyme. Please check with your doctor if you are using any herbs or supplements. ...Read more
Not related: The effect of Femara (letrozole) or of chemo on the cancer is unrelated to the platelet count. The choice between the two has to do with clinical characteristics of the cancer and the patient, not the blood counts. That said, if a patient's platelets are too low, it may not be possible to give chemo but that has to do with side effects, not effectiveness against the cancer. ...Read more

If you respect your own body or care about those who love you, make your decision on accurate information. ...Read more
Femara (letrozole) is metabolized in liver by cytochrome p450 system. Astaxanthin says "use cautiously w drugs metabolized by liver's cytochrome p450 enzyme system; does this mean don't use astaxanthin w femara (letrozole)?
Not necesarilly but: Virtually all drugs are metabolized by cytochrome p450 enzymes.

I no of no evidence that Femara (letrozole) is one of the drugs it interacts with. Small amounts of astaxanthin are unlikely to have much effect. Ask the doc who prescribed it. ...Read more

Most likely: Femara is the brand name for the drug letrozole, which is an aromatase inhibitor. This kind of drug blocks production of estrogen, making the body think it should create a surge of hormones like those that prompt ovulation. Letrozole is sometimes used in women being treated for infertility to induce ovulation. In post-menopausal women, ovulation will not occur, and Letrozole has other uses. ...Read more
Different action: Tamoxifen blocks the estrogen receptor, while Femara (letrozole) blocks the formation of estrogen. Estrogen levels are not lowered by tamoxifen, but they are lowered by femara (letrozole). Both cause hot flashes, bone loss, depression, memory problems and decreased libido. Tamoxifen increases blood clot and uterine cancer risk and causes vaginal discharge, while Femara (letrozole) causes more joint pain and vaginal dryness. ...Read more
