What is Xalkori?
Xalkori (crizotinib) is a cancer medication that interferes with the growth and spread of cancer cells in the body.
Xalkori is used to treat non-small cell lung cancer that has spread to other parts of the body.
Xalkori may also be used for purposes not listed in this medication guide.
Xalkori can cause serious heart or liver problems. Call your doctor at once if you have: fast or pounding heartbeats, sudden dizziness, shortness of breath, upper stomach pain, dark urine, clay-colored stools, or jaundice (yellowing of the skin or eyes).
Do not use Xalkori if you are pregnant. It could harm the unborn baby. Use effective birth control while you are using this medicine and for at least 3 months after your treatment ends, whether you are a man or a woman.
Before you take Xalkori, tell your doctor if you have liver or kidney disease, a heart rhythm disorder, an electrolyte imbalance (such as low levels of potassium or magnesium in your blood), or a personal or family history of Long QT syndrome.
