What is this medicine?
ERLOTINIB is a cancer medicine that interferes with the growth of cancer cells and slows their spread in the body. Erlotinib is used to treat non-small cell lung cancer or pancreatic cancer that has spread to other parts of the body (metastatic). Erlotinib is usually given after other cancer medicines have been tried without success.
