Consumer Medicine Information


This leaflet answers some common questions about Anastrozole Sandoz. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risk of you taking Anastrozole Sandoz against the benefits it is expected to have for you.

Anastrozole Sandoz 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.

Anastrozole Sandoz 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 Sandoz may slow or stop the growth of cancer.

Follow all directions given by your doctor. They may differ from the information contained in this leaflet.

Ask your doctor if you have any questions about why Anastrozole Sandoz was prescribed for you. Your doctor may have prescribed Anastrozole Sandoz for another reason.

Anastrozole Sandoz is only available with a doctor’s prescription.

Before you start to take it

Tell your doctor if you have allergies to:

  • any other substances, including foods, preservatives or dyes.

Tell your doctor if you plan on becoming pregnant or will be breastfeeding while you are using Anastrozole Sandoz.

Aromatase inhibitors may decrease bone mineral density (BMD) in women who have been through menopause, with a possible increased risk of fractures. Your doctor should discuss with you your treatment options for managing this possible increased risk of fractures.

If you have not told your doctor about any of the above, tell him/her before you start taking Anastrozole Sandoz.
