Tamoxifen Does Not Cause Depression. Nov. 6, 2001 -- There's been concern in recent years that the powerful breast cancer drug tamoxifen may cause or worsen depression. So much so, that it's even listed as a possible side effect in the Physician's Desk Reference.
Tamoxifen is a drug that binds to your estrogen receptors. Therefore it was thought that it could prevent excess estrogen binding, hence halting cancer from forming. It is generally prescribed to high-risk women to prevent breast cancer, and is usually taken for five years. However, Tamoxifen has been found to cause cancer instead. According to a study published in the International Journal of Gynecological Cancer, the treatment of breast cancer with tamoxifen results in an increased risk of uterine cancer incidence and mortality.
