Fuvestrol contains Fulvestrant, which is a type of hormone therapy used in breast cancer. It works by blocking the effect of estrogen (a female hormone) that helps some cancers to grow.

Mechanism 

• Some breast cancer cells need estrogen to grow.

• Fuvestrol (Fulvestrant) attaches to estrogen receptors on these cancer cells.

• It blocks the action of estrogen and also destroys the receptor.

• Without estrogen signaling, the cancer cells stop growing and may die.

  Uses

  • Used to treat hormone receptor-positive breast cancer in women, especially after menopause.

  • Often given when the cancer has spread (metastatic breast cancer).

  • Sometimes used if other hormone treatments have failed.

    • Hot flashes

    • Nausea

    • Injection site pain (since it is given as an injection)
