What Anastrozole RBX tablets are used for
Anastrozole RBX tablets are 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.
Anastrozole RBX tablets are 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 RBX may slow or stop the growth of cancer.
Follow all directions given to you by your doctor. They may differ from the information contained in this leaflet.
Ask your doctor if you have any questions about why Anastrozole RBX tablets have been prescribed for you. Your doctor may have prescribed Anastrozole RBX for another reason.
Anastrozole RBX tablets are only available with a doctor’s prescription.
Anastrozole RBX tablets are not addictive.
