Consumer Medicine Information

What is in this leaflet

This leaflet answers some of the common questions people ask about BICALOX. It does not contain all the information that is known about BICALOX.

It does not take the place of talking to your doctor or pharmacist. All medicines have risks and benefits. Your doctor will have weighed the risks of you taking BICALOX against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

What BICALOX is used for

BICALOX is used in combination with other medicines to treat locally advanced prostate cancer.

BICALOX is an anti-androgen medicine. Androgens such as testosterone are natural male sex hormones. In some types of prostate cancer, androgens can help the cancer cells to grow. Bicalutamide interferes with some of the actions of these hormones.

BICALOX should only be taken by men.

You must follow all the directions given to you by your doctor. They may differ from the information in this leaflet.

Your doctor may prescribe this medicine for another use.

Always ask your doctor if you need more information.

BICALOX is not addictive.

BICALOX is only available with a doctor’s prescription.

After taking it


Keep your BICALOX tablets in the blister foil until it is time to take them. If you take BICALOX out of the blister foil, it will not keep well.

Keep it in a cool dry place where the temperature stays below 30ºC. Protect from light and moisture.

Do not store it or any other medicine in the bathroom or near a sink.

Do not leave it on a window sill or in the car on hot days. Heat and dampness can destroy some medicines.

Keep your medicine where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.


Ask your pharmacist what to do with any tablets you have left over if your doctor tells you to stop taking them, or you find that the expiry date has passed.
