What is Cotellic?
Cotellic is a cancer medicine that interferes with the growth and spread of cancer cells in the body.
Cotellic is used in adults to treat a certain type of metastatic melanoma (skin cancer) that has spread to other parts of the body and cannot be removed with surgery. This medicine is usually given together with another medicine called Zelboraf (vemurafenib).
Cotellic is used only if your tumor has a specific genetic marker, for which your doctor will test.
Cotellic is also used alone to treat adults with blood cancers called histiocytic neoplasms.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
