Nolvadex® (Tamoxifen citrate) belongs to the group of cancer-fighting medications known as antineoplastics, and specifically to the type of antineoplastics known as antiestrogens. It is used in combination with other medications to treat early breast cancer.
Nolvadex® fights certain types of breast cancer, called hormone responsive or estrogen receptor positive breast cancer, by blocking the effects of the hormone estrogen in the body. This prevents the growth of the types of breast cancer cells that require estrogen for growth and survival. It is also used to treat breast cancer that is advanced or has spread to other parts of the body.
Nolvadex® (tamoxifen citrate) is contraindicated in patients with known hypersensitivity to the drug or any of its ingredients.
