Effects on your bones

Anastrozole lowers the levels of female sex hormones (oestrogens) in your body. This may reduce the mineral content of your bones. This means they may become weaker and there is a greater risk they may break. Your doctor will check the risks according to treatment guidelines for the management of osteoporosis in postmenopausal women. You should talk to your doctor about the risks and treatment options.

If you notice any side effects not mentioned in this leaflet, please tell your doctor or pharmacist.
