Exemestane is a hormonal cáncer de mama 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.

  • Si tienes algún problema con el funcionamiento de tu hígado, o algún problema con el funcionamiento de tus riñones.

  • If you have a loss of bone density, or 'brittle bones' - a condition known as osteoporosis.

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

  • Si está tomando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.

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.

Obteniendo el máximo de tu tratamiento

  • 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.

  • Si compras algún medicamento 'sin receta', consulta con un farmacéutico para asegurarte de que sea seguro tomarlo junto con tus medicamentos recetados.

Preguntas frecuentes

What is 'aromatase' and why is it important in treating breast cancer with exemestane?

Aromatase is an enzyme that helps change sex hormones called androgens into oestrogen in women who have been through menopause. Some breast cancers need oestrogen to grow. Exemestane works by blocking this aromatase enzyme, which lowers the amount of oestrogen in your body and slows the growth of these cancer cells.

Why do I need to take exemestane with food?

Although the article states to swallow the tablet 'preferably after a meal' and 'with a snack or something to eat' if a dose is missed, it doesn't elaborate on the specific reason why. It does, however, emphasize taking it with a meal for easier remembrance and consistent daily dosing, which helps with regular adherence to treatment.

Can I take exemestane if I haven't gone through menopause yet?

The article states that if you have not yet gone through menopause, or if there's a possibility of pregnancy, your doctor needs to know. This implies that exemestane is primarily intended for women post-menopause, and its suitability for pre-menopausal women requires careful consideration by a doctor.

How long will I need to take exemestane?

You may need to take exemestane for a number of years. You should continue to take the tablets regularly each day until your doctor tells you otherwise.

What should I do if I think I've taken too much exemestane?

Si sospecha que usted u otra persona podría haber tomado una sobredosis de este medicamento, debe acudir inmediatamente al departamento de accidentes y emergencias de su hospital local. Recuerde llevar el envase del medicamento con usted, incluso si está vacío.
