Casodex is an anti-androgen. It works in the body by preventing the actions of androgens (male hormones).
Casodex is used to treat prostate that has spread to other parts of the body (metastatic).
Casodex is given in combination with another medicine called a luteinizing (LOO-tee-in-ize-ing) hormone-releasing hormone, or LHRH. LHRH helps prevent the testicles from producing testosterone.
Casodex can harm your liver. Call your doctor at once if you have nausea, upper stomach pain, itching, loss of appetite, dark urine, clay-colored stools, or jaundice (yellowing of the skin or eyes).
