Tarceva (generic: erlotinib) is a prescription medication used to treat nonsmall cell lung cancer and pancreatic cancer. Tarceva belongs to a group of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells.
This medication comes in tablet form and is taken once a day, on an empty stomach.
Common side effects of Tarceva include diarrhea, loss of appetite, and nausea.
