Enzalutamide (Xtandi)

Find out what enzalutamide is, how you have it and other important information about having enzalutamide.

Enzalutamide is a cancer treatment and is also known by its brand name, Xtandi.

It is a treatment for advanced prostate cancer.

How it works

Prostate cancer needs testosterone to grow.

Enzalutamide stops your body from making testosterone. This can slow the growth of the cancer and may shrink it. 

Enzalutamide is a hormone treatment. This group of drugs is called androgen receptor agonists. 

How you have it

You take enzalutamide as capsules, once a day. You swallow them whole with a glass of water. You can have the capsules with or without food.

Taking capsules

You must take capsules according to the instructions your doctor or pharmacist gives you.

You should take the right dose, not more or less.

Never stop taking a cancer drug without talking to your specialist first.

When you have it

Enzalutamide is used in the treatment of prostate cancer that has spread to other parts of your body. 

Enzalutamide might be used when:

  • other hormone treatments are no longer working for you
