(Tamoxifen, Nolvadex)

Tamoxifen, commonly known by its brand name Nolvadex, is a medication used primarily to treat and prevent breast cancer. It works by blocking estrogen, a hormone that can promote the growth of some breast cancer cells. By interfering with estrogen's effects, tamoxifen helps slow or stop cancer growth. It is often prescribed for women after surgery or other treatments to reduce the risk of cancer recurrence. Tamoxifen may also be used for other hormonal conditions. While effective, it can have side effects like hot flashes, risk of blood clots, and changes in menstrual cycles, so it should be taken under medical supervision.
