What is Kisqali?
Kisqali is used to treat hormone-related breast cancer in women. Ribociclib is used only if your cancer tests negative for a protein called human epidermal growth factor receptor 2 (HER2). HER2 protein can speed the growth of cancer cells.
Kisqali is used when the cancer has progressed or has spread to other parts of the body after other treatments.
Kisqali can cause serious heart or liver problems. Call your doctor at once if you have fast or pounding heartbeats, sudden dizziness, right-sided upper stomach pain, loss of appetite, unusual bleeding or bruising, dark urine, or yellowing of your skin or eyes.
You will need frequent medical tests while taking Kisqali. Your cancer treatments may be delayed based on the results of these tests. Tell your doctor if you have signs of infection, such as fever or chills.
