What AROMASIN is used for
AROMASIN is used to treat breast cancer in women who no longer have their menstrual
periods, either naturally due to their age (after menopause) or because they have
had their ovaries surgically removed.
AROMASIN is used to reduce the risk of recurrence or spreading of the breast cancer.
It is also used when the cancer has not responded or has returned after treatment
with another medicine or medicines.
How AROMASIN works
AROMASIN is an aromatase inactivator. It works by significantly reducing the supply
of oestrogen to cancer cells.
This stops the growth of those cancer cells which need oestrogen, a natural female
sex hormone, to grow.
Ask your doctor if you have any questions about why AROMASIN has been prescribed for
Your doctor may have prescribed it for another purpose.
AROMASIN is only available with a doctor's prescription. It is not addictive.
