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

Warnings and precautions
• Before treatment with Aromasin, your doctor may want to take blood samples to

content of bones, which might decrease their strength.
