Xalkori - patient leaflet, side effects, dosage

1. What XALKORI is and what it is used for

XALKORI is an anticancer medicine containing the active substance crizotinib used to treat adults with a type of lung cancer called non-small cell lung cancer, that presents with a specific rearrangement or defect in either a gene called anaplastic lymphoma kinase (ALK) or a gene called ROS1.

XALKORI can be prescribed to you for the initial treatment if your disease is at an advanced stage of lung cancer.

XALKORI can be prescribed to you if your disease is at an advanced stage and previous treatment has not helped to stop your disease.

XALKORI may slow or stop the growth of lung cancer. It may help shrink tumours.

If you have any questions about how XALKORI works or why this medicine has been prescribed for you, ask your doctor.
