6. Further information
Your medicine is called Aromasin. Aromasin 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.
Aromasin 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.
Aromasin is also used to treat hormone dependent advanced breast cancer in
postmenopausal women when a different hormonal drug treatment has not worked well

• 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 Aromasin. 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.

Please tell your doctor if you are taking or have recently taken any other medicines,
including medicines obtained without a prescription.

Important information about some of the ingredients of Aromasin
If you have previously been told that you have intolerance to some sugars, contact
your doctor before taking this medicine. Aromasin tablets contain sucrose (a type of
sugar), which may cause a problem in a small number of patients with hereditary
intolerance to some sugars (glucose-galactose malabsorption, fructose intolerance or
sucrose-isomaltase insufficiency).
• Aromasin contains a small amount of methyl parahydroxybenzoate, which may cause
allergic reactions (possibly delayed), if this should happen please contact your doctor.

Adults and the elderly
Aromasin tablets should be taken by mouth after a meal at approximately the same
time each day. Your doctor will tell you how to take Aromasin and for how long. The
recommended dose is one 25 mg tablet daily.
Do not stop taking your tablets even if you are feeling well, unless your doctor tells you.
If you need to go to the hospital whilst taking Aromasin, let the medical staff know what
medication you are taking.
