Product Information


Tamofar 20 contains 20mg of the active ingredient Tamoxifen citrate. Tamoxifen belongs to a class of drugs called selective estrogen receptor modulators (SERMs) which possess both estrogenic and anti-estrogenic effects.


Tamoxifen is prescribed for the following:

  • As an adjuvant therapy for lymph node negative or positive breast cancer in both women and men.

Tamoxifen is more likely effective in cancers with positive estrogen and progesterone receptors. This drug reduces the risk of having breast cancer on the opposite breast.

  • Treatment of metastatic breast cancer in women and men.
  • Treatment of ductal carcinoma in situ in women, following surgery and radiation therapy.

Tamoxifen may reduce the risk of invasive breast cancer.

  • As a preventive therapy to reduce the risk of developing breast cancer for women who are at a high risk due to age and family or personal medical history.


Tamoxifen works by binding to estrogen receptors in the cancer cells and blocks the estrogen’s proliferative effects on breast tissues, stopping the growth of breast tumors that require estrogen.




Tamofar 20 is manufactured by Shree Venkatesh International
