What is Ibrance?

Ibrance (palbociclib) is a medicine known as a kinase inhibitor, which blocks the action of a protein that triggers the growth of cancer cells. Ibrance is used with another drug, letrozole, to treat a particular form of advanced breast cancer. It is supplied in capsule form, and is taken for the first three weeks of each four-week cycle. Ibrance may interact with medications and supplements; make sure your doctor knows about everything you are taking. Pregnant women and those breastfeeding should not take Ibrance; if you plan to become pregnant after treatment, wait at least two weeks following the last dose. Ibrance is not approved for children. Side effects may include hair thinning, nausea, vomiting, diarrhea, fatigue, poor appetite, and numbness or tingling in the extremities. Get medical help immediately if you experience signs of infection (fever, chills), irregular breathing or heartbeat, weakness, chest pain, and unusual bleeding or bruising (including nosebleeds).
