About your treatment Return to top

Your doctor has ordered erlotinib to help treat your illness. Erlotinib comes as a tablet to take by mouth. It is usually taken once a day on an empty stomach. Take erlotinib at least 1 hour before or 2 hours after you eat a meal or snack. To help you remember to take erlotinib, take it at around the same time every day.

Follow the directions on your prescription label carefully and ask your doctor or pharmacist to explain anything you do not understand. Take erlotinib exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Do not stop taking erlotinib without talking to your doctor.

This medication is used to treat non-small cell lung cancer (a type of cancer that begins in the lungs) in patients who have already been treated with at least one other chemotherapy medication and have not gotten better.

Erlotinib is in a class of drugs known as Human Epidermal Growth Factor Receptor Type 1/Epidermal Growth Factor Receptor (HER1/EGFR) tyrosine kinase inhibitors. It slows the growth of cancer cells. The length of your treatment depends on the types of drugs you are taking, how well your body responds to them, and the type of cancer you have. Be sure to tell your doctor how you are feeling during your treatment.
