|Type of medicine||An aromatase inhibitor hormone antagonist|
|Used for||Breast cancer in women|
Exemestane is a hormonal breast cancer treatment.
Some breast cancers need the hormone oestrogen to grow. In women who have been through the menopause, the main source of oestrogen is through the change of sex hormones, called androgens, into oestrogen. An enzyme called 'aromatase' is needed for this change to occur. Exemestane works by blocking (inhibiting) this enzyme. This reduces the amount of oestrogen in your body, which slows the growth of the cancer cells.
Before taking exemestane
Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking exemestane it is important that your doctor knows:
- If you have not yet gone through the menopause, or if there is a possibility you could be pregnant.
- If you have any problems with the way your liver works, or any problems with the way your kidneys work.
- If you have a loss of bone density, or 'brittle bones' - a condition known as osteoporosis.
- If you have ever had an allergic reaction to a medicine.
- If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.
How to take exemestane
- Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about exemestane and it will also provide you with a full list of the side-effects which you could experience from taking it.
- Take one 25 mg tablet of exemestane each day, exactly as your doctor tells you to.
- Swallow the tablet with a drink of water, preferably after a meal.
- You can take exemestane with whichever meal of the day you find easiest to remember, but try to take your doses with the same meal each day. This will help you to remember to take exemestane regularly.
- If you forget to take a dose at your usual time, take it (with a snack or something to eat) as soon as you remember. If you do not remember until the following day, leave out the forgotten dose from the previous day and take the dose that is due as normal. Do not take two doses on the same day to make up for a missed dose.
- Continue to take the tablets regularly each day until your doctor tells you otherwise. You may need to take exemestane for a number of years.
Getting the most from your treatment
- Try to keep your regular appointments with your doctor and clinic. This is so your doctor can check on your progress. Exemestane lowers the levels of female hormones in your body, which can reduce the strength of your bones. You may need to have bone density tests to check for this before and during your treatment.
- If you are due to have an operation or any dental treatment, tell the person carrying out the treatment that you are taking exemestane.
- If you buy any medicines 'over the counter', check with a pharmacist that they are safe to take with your prescribed medicines.
