What is Verzenio?
Verzenio (abemaciclib) is a cancer medicine that interferes with the growth and spread of cancer cells in the body.
Verzenio is used to treat advanced hormone-related breast cancer.
Verzenio is used for this condition only if your tumor tests negative for a protein called human epidermal growth factor receptor 2 (HER2). HER2 protein can speed the growth of cancer cells.
Verzenio is used when the cancer has progressed or has spread to other parts of the body after treatment with anti-estrogen medication or other chemotherapy.
When used in women, Verzenio is given with another medicine called fulvestrant.
Verzenio can cause severe severe diarrhea, which can lead to dehydration or infection. Call your doctor right away if you have diarrhea. Drink extra fluids and start taking anti-diarrhea medicine such as loperamide (Imodium).
Verzenio can cause blood clots, liver problems, or serious and sometimes fatal infections. Call your doctor right away if you have symptoms such as: fever, chills, easy bruising or bleeding, unusual tiredness, loss of appetite, right-sided upper stomach pain, chest pain, shortness of breath, rapid breathing, fast heartbeats, or pain or swelling in your arms or legs.

If you have diarrhea while taking Verzenio: start taking anti-diarrhea medicine such as loperamide (Imodium) to quickly treat diarrhea. Drink extra fluids and call your doctor.
Abemaciclib can lower blood cells that help your body fight infections and help your blood to clot. Your blood will need to be tested often. Your cancer treatments may be delayed based on the results of these tests.
