Tamoxifen is the oldest and most-prescribed selective estrogen receptor modulator (SERM). Tamoxifen is approved by the U.S. Food and Drug Administration (FDA) to treat:
- women and men diagnosed with hormone-receptor-positive, early-stage breast cancer after surgery (or possibly chemotherapy and radiation) to reduce the risk of the cancer coming back (recurring)
- women and men diagnosed with advanced-stage or metastatic hormone-receptor-positive disease
Tamoxifen also is used to:
- reduce breast cancer risk in women who haven’t been diagnosed but are at higher-than-average risk for the disease
Tamoxifen won’t work on hormone-receptor-negative breast cancer.
Tamoxifen is available in two forms: a pill taken once a day (brand name: Nolvadex) or a liquid form (brand name: Soltamox). If you dislike pills or you’re having trouble swallowing tamoxifen pills, Soltamox can help make it easier to stay on your treatment plan.
Chemical Name: Tamoxifen (ta-MOX-i-fen)
Tamoxifen is a TABLET but CANNOT be split in half.
Tamoxifen is a medicine that blocks the effects of the estrogen hormone in the body. It is used to treat breast cancer in women or men. It may also be used to treat other kinds of cancer, as determined by your doctor.
