Take four tablets together, once a day. Swallow the tablets whole, with water.
Take the tablets when your stomach is empty. This means taking your dose at least an hour before a mealtime, or waiting for two hours afterwards.
You will also be prescribed another medicine (either prednisone or prednisolone) to take alongside abiraterone. It is important that you take it regularly every day.
|Type of medicine||An anti-androgen medicine|
|Used for||Advanced prostate cancer|
In some men with prostate cancer, the cancer cells spread to parts of the body other than the prostate. 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.
Abiraterone is a hormone treatment - it belongs to a group of medicines known as anti-androgens. This means that it reduces the amount of male sex hormones (called androgens) that your body produces. In prostate cancer, androgens are produced by your testicles (testes), by your adrenal glands, and in the tumour cells. Abiraterone reduces the amount of androgens produced by each of these, and this slows the growth of the cancer.
Before taking abiraterone
Sometimes a medicine may only be used in people with certain conditions if extra care is taken. For this reason, before you start taking abiraterone it is important that your doctor knows:
- If you have been told you have high blood pressure, or low levels of potassium in your blood.
- If you have heart or blood vessel problems.
- If you have diabetes.
- If you have any problems with the way your kidneys work, or any problems with the way your liver works.
- If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines.
- If you have ever had an allergic reaction to a medicine.
How to take abiraterone
- Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about abiraterone and will provide you with a full list of the side-effects which you may experience from taking it.
- Take abiraterone exactly as your doctor tells you to. The usual dose is four 250 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.
- You must take the tablets when your stomach is empty. This means that you should take abiraterone at least an hour before a mealtime, or wait until at least two hours after you have eaten. This is because taking abiraterone with food will increase the amount of the medicine in your blood in a way that isn't predictable, and this is likely to cause side-effects.
- Take the tablets with a drink of water. Swallow the tablets whole - do not crush or break the tablets in order to swallow them.
- Try to take abiraterone at the same time of day each day as 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.
Getting the most from your treatment
- Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress. You will need to have regular blood tests to check on the amount of potassium in your blood and how well your liver is working. Your doctor will also want to check your blood pressure routinely.
- It is important that you continue to take the prednisone or prednisolone tablets that you will be prescribed alongside abiraterone. You should take these tablets regularly every day. Do not stop taking them unless your doctor tells you to.
- If you have diabetes you will need to check your blood glucose more frequently as these tablets can increase the level of sugar in your blood. Your doctor will advise you about this.
- If you are having an operation or dental treatment, tell the person carrying out the treatment which medicines you are taking. This is important because your dose of prednisone or prednisolone may need to be increased for a short while.
- Abiraterone 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.
- If you buy any medicines, check with a pharmacist that they are safe to take with your other medicines.
