Casodex

This page is about the hormone therapy Casodex (bicalutamide) that is a treatment for advanced prostate cancer.

Prostate cancer depends on the male sex hormone, testosterone, to grow. Testosterone is a type of hormone called an androgen. Bicalutamide is an anti-androgen. It stops testosterone reaching the cancer cells. This can shrink the cancer or slow its growth. Casodex is not a cure or treatment for prostate cancer but with Lupron, can add in slowing down the cancer and making it more susceptible to radiation therapy.

You may have a few side effects. They may be mild or more severe. A side effect may get better or worse through your course of treatment. Or more side effects may develop as the course goes on.

The side effects may be different if you are having bicalutamide with other medicines.
