    Corrections and clarifications: An earlier version of this story misstated Anna Kessler's relationship to the petition before the U. Tamoxifen binds to estrogen receptors, cutting off the hormone so it can no longer feed the growth of cancer cells. DETROIT — For millions with breast cancer, it's a cornerstone drug for keeping the disease at bay. Deprived of the estrogen, the cancerous cells eventually die. Now an Oakland County, Mich., woman and breast cancer survivor is among a growing number of voices that want the U. Food and Drug Administration to change its labeling on the drug — recommending its use for 10 years instead of the current five. That would bring the federal labeling in line with recommendations earlier this year by two behemoths in the cancer treatment field — the American Society of Clinical Oncology and the National Comprehensive Cancer Network. The two organizations changed their recommendations after two studies suggested that for women who are premenopausal and for whom the risk of recurring cancer is high, doubling the time tamoxifen is taken is more effective. For patients trying to sort out treatment options in the middle of crisis and fear, a discrepancy between current labeling and what their doctor recommends only adds to confusion, said Anna Kessler, who was diagnosed with breast cancer when she was 42. In 2006, the large STAR clinical study concluded that raloxifene is equally effective in reducing the incidence of breast cancer, but after an average 4-year follow-up, although the difference was not statistically significant, there were 36% fewer uterine cancers and 29% fewer blood clots in women taking raloxifene than in women taking tamoxifen. Tamoxifen improves fertility in males with infertility by disinhibiting the hypothalamic–pituitary–gonadal axis (HPG axis) via ER antagonism and thereby increasing the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) and increasing testicular testosterone production. It is taken as a preventative measure in small doses, or used at the onset of any symptoms such as nipple soreness or sensitivity. Other drugs are taken for similar purposes such as clomifene and the anti-aromatase drugs which are used in order to try to avoid the hormone-related adverse effects. Occasionally tamoxifen is used in treatment of the rare conditions of retroperitoneal fibrosis A report in September 2009 from Health and Human Services' Agency for Healthcare Research and Quality suggests that tamoxifen, raloxifene, and tibolone used to treat breast cancer significantly reduce invasive breast cancer in midlife and older women, but also increase the risk of adverse side effects. Some cases of lower-limb lymphedema have been associated with the use of tamoxifen, due to the blood clots and deep vein thrombosis (DVT) that can be caused by this medication. Resolution of the blood clots or DVT is needed before lymphedema treatment can be initiated.

Tamoxifen, a selective estrogen receptor modulator, is an FDA approved drug. Results suggest that the mechanism of action of Tamoxifen. The drug tamoxifen is approved by the U. S. Food and Drug Administration FDA to help treat early and advanced stages of breast cancer and prevent breast cancer.

    Tamoxifen is a drug credited with saving the lives of hundreds of thousands of women around the world, and extending the lives of millions more. Listed by the World Health Organisation as an essential drug for the treatment of breast cancer, Tamoxifen has been a critical weapon in the fight against this disease for more than 35 years. First made in 1966, Tamoxifen was intended as a new contraceptive drug, before scientists realised that it could be useful for treating breast cancer. In 1977 it was approved for use in patients with advanced breast cancer, and during the 1970s and 80s, a number of clinical trials showed it to be safe and effective for the treatment of breast cancer more broadly. Tamoxifen has become the gold standard treatment for women with a type of breast cancer called ‘oestrogen receptor positive’ (or ER positive), which account for about 8 out of every 10 breast cancers diagnosed. These cancers grow in response to the hormone oestrogen, and so are responsive to drugs like Tamoxifen that act to block oestrogen from entering cancer cells. Tamoxifen offers an important advantage over chemotherapy drugs by specifically targeting cancer cells, and leaving normal cells unharmed. A new “black box” Food and Drug Administration warning on tamoxifen may just make Therese Bevers’ difficult job a little harder. Bevers, medical director of the Cancer Prevention Center at the University of Texas M. Anderson Cancer Center, spends a great deal of time easing the apprehension many primary care physicians feel over prescribing tamoxifen to their patients who are at high risk for developing breast cancer (see main story). Now she’s concerned that the new FDA warning on the label about the risk of developing a rare, aggressive form of uterine cancer may impede her progress. Documents released by the FDA in June include the revised label, “Dear Doctor” letters, and a new patient insert, all of which are largely aimed at use of the drug for chemoprevention. Although tamoxifen use has long been associated with an elevated risk of developing the most common form of endometrial cancer, which is relatively treatable, recent data indicate a newly recognized increased risk of a more deadly uterine sarcoma. For example, long-term follow-up on 8,306 women with an intact uterus who participated in the BCPT trial show that endometrial cancer was reported in 53 women who took tamoxifen and 17 who were prescribed a placebo, and 4 women who used tamoxifen in the trial developed a uterine sarcoma, while no cases appeared in the placebo group. The job for Bevers is to put those numbers into perspective.

    So you think you have a yeast infection and you buy an over-the-counter (OTC) treatment, but four days later you are still very itchy/irritated/burning like crazy. First of all you need this background information: If you were right then there is a 85-90% chance that you should be better. The next step, for most women, is to call their GYNO and ask for fluconazole, known by many under the brand name Diflucan, or to retreat with a OTC topical. If you guessed correctly and aren’t better more of the same (i.e. trying fluconazole/Diflucan or another OTC medication) is not likely to be any better because the oral and topicals work in the same way. If you are not feeling better after treatment (which will happen 75% of the time just looking at the statistics) there are five possible scenarios: Put another way, if 100 women use OTC medication for vaginal yeast, 70 will have persistent symptoms because they never had yeast to begin with and 5 will still have persistent symptoms related to yeast. That means if you have persistent symptoms there is a 93% chance you never had yeast and a 7% chance that you did, but need further information to treat. The chance that more of the same will help is very slim. Other clinical pearls: A bad yeast infection can take seven days to feel a lot better, An antihistamine, like Zyrtec or Claritin, will help you feel better faster and a low dose topical steroid on the vulva (labia and vaginal opening) will also help if there is a lot of external irritation But the OTC always fails for me and the Diflucan always works! This is unlikely related to the type of medication (OTC vs prescription) and more a mechanical issue – some women place the vaginal medication too low in their vagina (if the tissues are really inflamed it can be harder to get high enough).
