Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This is because Anastrozole can affect the way some medicines work and some medicines can have an effect on Anastrozole.

Do not take Anastrozole if you are already taking any of the following medicines:

• certain medicines used to treat breast cancer (selective estrogen receptor modulators), e.g., medicines that contain tamoxifen. This is because these medicines may stop Anastrozole from working properly.

If this applies to you, ask your doctor or pharmacist for advice.

Tell your doctor or pharmacist if you are taking the following:

• a medicine known as an ‘LHRH analogue’. This includes gonadorelin, buserelin, goserelin, leuprorelin and triptorelin. These medicines are used to treat breast cancer, certain female health (gynaecological) conditions, and infertility.

Anastrozole lowers the amount of the hormone called estrogen that is in your body. This may lower the mineral content of your bones. Your bones may be less strong and may be more likely to fracture. Your doctor will manage these risks according to treatment guidelines for managing bone health in women who have gone through the menopause. You should talk to your doctor about the risks and treatment options.
