What this medicine is used for
Anastrozole is used to treat breast cancer in women who no longer have their menstrual periods either naturally, due to their age or after surgery, radiotherapy or chemotherapy.
How it works
Anastrozole is a non-steroidal aromatase inhibitor, which reduces the amount of oestrogen (female sex hormone) made by the body. In some types of breast cancer, oestrogen can help the cancer cells grow. By blocking oestrogen, anastrozole may slow or stop the growth of cancer.

Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor’s prescription.
This medicine is not addictive.
