Erlotinib Overview

Updated: 

Erlotinib is a prescription medication used to treat non-small cell lung cancer that has spread to nearby tissues or to other parts of the body in patients. It is used when other treatments have not succeeded. Erlotinib is also used to treat pancreatic cancer that has spread to nearby tissues or to other parts of the body. Erlotinib belongs to a group of drugs called kinase inhibitors. These work by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells.

Erlotinib comes as a tablet to take by mouth. It is usually taken on an empty stomach once a day, at least 1 hour before or 2 hours after eating a meal or snack. Take erlotinib at around the same time every day.

Common side effects include rash, diarrhea, and tiredness. Do not drive or operate heavy machinery until you know how erlotinib will affect you.
