Why is this medication prescribed?
Ceritinib is used to treat non-small cell lung cancer (NSCLC) that has spread to nearby tissues or to other parts of the body in patients who have already been treated with at least one other chemotherapy medication and have not improved or whose condition has worsened. Ceritinib is in a class 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.
How should this medicine be used?
Ceritinib comes as a capsule to take by mouth. It is usually taken on an empty stomach once a day, either at least 2 hours before or 2 hours after eating a meal or snack. Take ceritinib 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 ceritinib exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor may decrease your dose of ceritinib or tell you to stop taking ceritinib for a period of time during your treatment. This will depend on how well the medication works for you and any side effects you may experience. Be sure to tell your doctor how you are feeling during your treatment with ceritinib.
