1. What Exemestane is and what it is used for
2. What you need to know before you take Exemestane
3. How to take Exemestane
4. Possible side effects
5. How to store Exemestane
6. Contents of the pack and other information
Your medicine is called Exemestane. Exemestane belongs to a group of medicines known
as aromatase inhibitors. These drugs interfere with a substance called aromatase, which
is needed to make the female sex hormones, oestrogens, especially in postmenopausal
women. Reduction in oestrogen levels in the body is a way of treating hormone
dependent breast cancer.
Exemestane is used to treat hormone dependent early breast cancer in postmenopausal
women after they have completed 2-3 years of treatment with the medicine tamoxifen.
Exemestane is also used to treat hormone dependent advanced breast cancer in
postmenopausal women when a different hormonal drug treatment has not worked
well enough.
Do not take Exemestane
• if you are or have previously been allergic to exemestane (the active ingredient in
Exemestane) or any of the other ingredients of this medicine (listed in section 6).
• if you have not already been through ‘the menopause’, i.e. you are still having
your monthly period.
• if you are pregnant, likely to be pregnant or breast-feeding.
Warnings and precautions
• Before treatment with Exemestane, your doctor may want to take blood samples
to make sure you have reached the menopause.
• Routine checking of your vitamin D level will also be made before treatment, as
your level may be very low in the early stages of breast cancer. You will be given
vitamin D supplement if your levels are below normal.
• Before taking Exemestane, tell your doctor if you have problems with your liver
or kidneys.
• Tell your doctor if you have a history or are suffering from any condition which
affects the strength of your bones. Your doctor may want to measure your bone
density before and during the treatment of Exemestane. This is because drugs of
this class lower the levels of female hormones and this may lead to a loss of the
mineral content of bones, which might decrease their strength.
Other medicines and Exemestane

medicines, including medicines obtained without a prescription.
