Bicalutamide belongs to a group of medicines known as anti-androgens. This means that it blocks the actions of male sex hormones called androgens and it also reduces the amount of male hormones (such as testosterone) that your body produces.

In prostate cancer, the cancer cells need the male hormone testosterone to grow and multiply well. Hormone treatments like bicalutamide block the effect of testosterone on prostate cancer cells. This slows down the growth of the cancer. Bicalutamide also helps to reduce symptom 'flares' and side-effects from other treatments which may be used for the cancer, or following surgery.

Before taking bicalutamide

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 bicalutamide it is important that your doctor knows:

  • Si tiene algún problema con el funcionamiento de su hígado.

  • Si toma o utiliza otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que pueda adquirirse sin receta, así como medicamentos a base de plantas y complementarios.

  • Si alguna vez ha tenido una reacción alérgica a un medicamento.

How to take bicalutamide

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

  • Take bicalutamide exactly as your doctor tells you to. Your dose will be printed on the label of the pack of tablets to remind you about what the doctor said to you. The usual dose is one tablet each day. There are two strengths of tablet available: 50 mg and 150 mg. The strength of tablet that you are prescribed will depend on whether you are also having other treatments.

  • You can take bicalutamide tablets either before or after meals. Taking the tablet with a drink of water will help you to swallow it.

  • Try to take the tablet at the same time of day each day. This will help you to remember to take your doses regularly.

  • If you forget to take a dose at your usual time, take it when you remember. If you do not remember until the following day then leave out the forgotten dose and take your next dose when it is due. Do not take two doses on the same day to make up for a missed dose.

  • Please keep your regular appointments with your doctor. Your doctor may want you to have some blood tests from time to time to check that your liver is staying healthy.

  • Treatment with bicalutamide is often long-term. You should continue to take the tablets regularly unless you are told otherwise by your doctor.
