Kind of Cancers It Is Used For (not a complete list)

Your oncology team decides how and when axitinib is used based on your specific cancer and overall health.

Mechanism of Action

Axitinib is a tyrosine kinase inhibitor (TKI). It blocks vascular endothelial growth factor receptors (VEGFR-1, -2, and -3). These receptors help tumors grow new blood vessels. By blocking them, axitinib cuts off the blood supply tumors need. This may slow tumor growth or help shrink the cancer.

Common Side Effects

  • Stomach and bowel problems: constipation, diarrhea, nausea, vomiting, upset stomach, stomach pain, or heartburn.
  • Mouth problems: mouth irritation or sores; change in taste.
  • Energy changes: feeling tired, weak, or dizzy; headache.
  • Appetite and weight: decreased appetite; weight loss.
  • Skin and hands/feet: dry skin; redness or irritation on the palms and soles.
  • Muscles and joints: muscle or joint pain.
  • Respiratory: cough.
  • Extremities: pain in arms or legs.

These are not all the possible side effects. Some side effects are common and mild; others can be serious. If side effects bother you, do not go away, or feel severe, contact your care team. You may need tests to check blood pressure, thyroid, liver, kidneys, electrolytes, and urine while on this medicine. In some cases, your team may adjust treatment.
