What this medicine is used for

The name of your medicine is APO-Bicalutamide. It contains the active ingredient bicalutamide.

It is used in combination with other medicines called LHRH agonists to treat advanced prostate cancer and to prevent a side effect of LHRH agonists.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.

This medicine is available only with a doctor's prescription.

How it works

Bicalutamide is an anti-androgen medicine. Androgens such as testosterone are natural male sex hormones. In some types of prostate cancer, androgens may help the

cancer cells to grow.

Bicalutamide interferes with some of the actions of these hormones.

Bicalutamide should only be taken by men.

There is no evidence that this medicine is addictive.

Use in children

This medicine must not be used in children.
