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 together with another hormone to treat prostate cancer.
Casodex may also be used for purposes not listed in this medication guide.
Casodex is used to treat prostate cancer. This medicine should never be taken by a woman or a child.
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).
Before taking this medicine
You should not use Casodex if you are allergic to bicalutamide.

How should I take Casodex?
Take Casodex exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Casodex is usually taken once per day in the morning or evening. You may take the medicine with or without food. Try to take the medication at the same time each day.
Casodex is given as part of a combination prostate cancer treatment with another medicine called a luteinizing (LOO-tee-in-ize-ing) hormone-releasing hormone, or LHRH. These medicines prevent the testicles from producing testosterone.
Treatment with Casodex and LHRH is usually started at the same time. Follow your doctor's instructions.
LHRH is given as an injection or a tiny implant injected through a needle under the skin around your navel. LHRH injections are given at intervals such as once every 4 weeks. Follow your doctor's instructions.
You should not stop using Casodex unless your doctor tells you to do so.
While using Casodex, you may need frequent blood tests at your doctor's office.
Store at room temperature away from moisture and heat.
