What is Casodex?
Casodex (bicalutamide) is an anti-androgen. It works in the body by preventing the actions of androgens (male hormones).
Casodex is used to treat prostate cancer 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 is used to treat prostate cancer. This medicine should never be taken by a woman or a child.
Bicalutamide can harm an unborn baby if you father a child while using this medicine. Use effective birth control to prevent pregnancy while using Casodex and for at least 130 days (about 19 weeks) after your last dose.
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).
