Fareston (Toremifene Citrate)

Drug:Fareston Tablet
Country:United Kingdom
Dosage:60 mg

Fareston (Toremifene Citrate) is a prescription medication used in postmenopausal women to treat (metastatic) hormone-receptor-positive breast cancer (cancer that has spread to other parts of the body). Your doctor may test your tumor before prescribing this medication. Fareston may also be used for purposes not listed above. Fareston belongs to a class of medications called estrogen antagonists, and works to treat cancer by blocking estrogen from reaching cancer cells. Certain breast cancers are hormone receptor-positive, meaning that when the cancer cells receive estrogen, they grow and spread. By blocking the estrogen from reaching the cancer cells, Fareston can slow the spread and growth of the cancer.
