What is Tagrisso?

Tagrisso is a treatment for cancer that blocks the spread and growth of cancerous cells within the body. Tagrissois is used to treat non-small-cell lung cancer, which contains an abnormal "EGFR" gene. The doctor will test you to determine if you have this particular gene. Tagrisso can be prescribed when a tumour has advanced to different regions of your body (metastatic) and to prevent lung cancer from recurring following the time your tumour(s) were removed through surgery. Tagrisso may also be prescribed when the cancer of your lungs has spread to different areas of your body and you previously had treatment using an EGFR medication that inhibits tyrosine kinase that didn't work or stopped being effective.


Tagrisso could cause lung problems that could cause death. The symptoms may be similar to those of lung cancer. Contact your physician immediately if you notice any recent or deteriorating lung symptoms like breathing difficulties, shortness of breath, coughing, or fever.

Tagrisso could cause heart problems that could cause death. Your physician should examine your heart's health before you begin to take this medication as well as during treatment. Contact your doctor immediately if you experience any of the following signs or symptoms of a heart issue: feeling that your heart is beating or racing, breathing shortness, swelling of your feet and ankles, or feeling faint.
