Enzalutamide for prostate cancer

About enzalutamide

In some men with prostate cancer, the cancer cells spread to parts of the body other than the prostate gland. When this happens, it is referred to as late, advanced or metastatic prostate cancer. Treatment options for this type of cancer typically include hormone treatment, surgery, radiotherapy and chemotherapy.

Enzalutamide is a hormone treatment - it belongs to a group of medicines known as anti-androgens. It works by blocking the action of male hormones called androgens. Testosterone is an androgen. Prostate cancer cells need the male hormone testosterone to grow and multiply well. By blocking the action of androgens such as testosterone, enzalutamide slows the growth of the cancer cells.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking enzalutamide it is important that your doctor knows:

• If you have ever had a fit (seizure) or if you have been told you may be at risk of having a seizure.

• If you have heart or blood vessel problems.

• If you have any problems with the way your kidneys work or any problems with the way your liver works.

• Om du tar eller använder några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.

• Om du någonsin har haft en allergisk reaktion mot en medicin.

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about enzalutamide and will provide you with a full list of the side-effects which you may experience from taking it.

• Take enzalutamide exactly as your doctor tells you to. The usual dose is four 40 mg tablets taken together, once a day. Your dose will be printed on the label of the pack to remind you about what the doctor said to you.

• Take the tablets with a drink of water. Swallow the tablets whole - do not break or chew the tablets.

• You can take your doses either before or after food, but try to take enzalutamide at the same time of day each day. This will help you to remember to take your doses regularly.

• If you do forget to take a dose, take it as soon as you remember. If you do not remember until the following day, skip the forgotten dose. Do not take two doses together to make up for a missed dose.

• Försök att hålla dina regelbundna möten med din läkare. Detta är så att din läkare kan följa upp din utveckling.

• If you buy any medicines 'over the counter', always check with a pharmacist that they are suitable for you to take with your other medicines.

• If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking enzalutamide.

• Enzalutamide may harm an unborn child. This means that if you are having sex with a woman who could become pregnant, you must use a condom along with another effective birth control method. If you are having sex with a woman who is already pregnant, you must use a condom to protect the unborn child.
