As always, it’s important to keep your cancer care team aware of how you’re feeling. But it’s even more important when you’re starting a treatment such as XALKORI. Always tell your healthcare provider if you have any side effect that bothers you or does not go away. Your healthcare provider may change the dose of XALKORI or some of your other medications, choose different medicines while you are taking XALKORI, or stop your treatment.
