Afatinib is used to treat certain types of non-small cell lung cancer that has spread to nearby tissues or to other parts of the body. Afatinib is in a class of medications called kinase inhibitors. It works by blocking the action of a certain naturally occurring substance that may be needed to help cancer cells multiply.
Afatinib 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 afatinib at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take afatinib exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor may temporarily or permanently stop your treatment or decrease the dose if you experience serious side effects of afatinib. Talk to your doctor about how you are feeling during your treatment.
Continue to take afatinib even if you feel well. Do not stop taking afatinib without talking to your doctor.
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
