How should I take bicalutamide?

Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Bicalutamide is given as part of a combination prostate cancer treatment with another medication called a luteinizing (LOO-tee-in-ize-ing) hormone-releasing hormone, or LHRH. This medication prevents the testicles from producing testosterone.

Treatment with bicalutamide and LHRH is usually started at the same time. Follow your doctor's instructions.

Bicalutamide 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.

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 bicalutamide suddenly. Stopping suddenly may make your condition worse.

While using bicalutamide, you may need frequent blood tests at your doctor's office.

Store at room temperature away from moisture and heat.

What happens if I miss a dose?

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

Call your doctor for instructions if you miss an appointment for your LHRH injection.
