For which conditions is this drug approved? Inlyta is approved for the treatment of advanced renal cell carcinoma (kidney cancer) when prior treatment hasn’t worked.

What is the mechanism of action? Inlyta is a kinase inhibitor. These drugs work by blocking the action of enzymes called kinases, which are involved in many cell functions, including cell signaling, growth, and division. These enzymes may be too active or found at high levels in some types of cancer cells, and blocking them may help keep cancer cells from growing.

How is Inlyta typically given (administered)? Inlyta is given orally, as a tablet.

How are patients typically monitored? While you are taking Inlyta, your doctor will monitor your blood pressure, thyroid function, liver function, and check you for a condition called proteinuria in which your urine contains an abnormal amount of protein.

planned surgery.
  • Tell your doctor about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements. Inlyta and certain other medicines can affect each other causing serious side effects.
