How does this medication work? What will it do for me?
Ceritinib belongs to the group of cancer-fighting medications known as antineoplastics and more specifically to a class of medications called protein kinase inhibitors. These medications slow the growth of blood vessels that feed nutrients to cancer cells. By slowing the growth of these blood vessels, ceritinib can help reduce the size of tumours.
Ceritinib is used to treat anaplastic lymphoma kinase (ALK)-positive non-small-cell lung cancer that cannot be cured by surgical removal or that has spread to other parts of the body. This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Abnormal heart rhythms: This medication can cause abnormal heart rhythms. Certain medications (e.g., sotalol, quinidine, thioridazine, chlorpromazine, pimozide, moxifloxacin, mefloquine, pentamidine, arsenic trioxide, tacrolimus) can increase the risk of a type of abnormal heart rhythm called QT prolongation and should not be used in combination with ceritinib. You are more at risk for this type of abnormal heart rhythm and its complications if you:
If you have heart disease and abnormal heart rhythms or are taking certain medications (e.g., verapamil, atazanavir), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Birth control: Use effective birth control while using this medication, as this medication may harm the baby if used during pregnancy. Both men and women should use effective birth control (e.g., condoms, birth control pill) during treatment and for at least 90 days after treatment is finished. If you or your partner become pregnant while taking this medication, contact your doctor immediately.
Diabetes: This medication can cause increases in blood sugar. If you have diabetes or a family history of diabetes, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Heart problems: This medication can decrease heart rate, which may contribute to heart failure or worsen symptoms of heart disease. If you have heart disease such as angina, congestive heart failure, or arrhythmia, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. If you experience a heart rate of less than 60 beats per minute, or frequently feel faint or dizzy, contact your doctor.
Kidney problems: If you have severe kidney problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. Ceritinib may also reduce liver function and can cause severe liver problems. Your doctor will monitor your liver function with blood tests while you are taking this medication. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.
Lung inflammation: Lung inflammation (interstitial lung disease) causing difficulty breathing has occurred rarely in some people taking this medication. This complication can be serious and sometimes fatal. If you experience new or worsening shortness of breath or cough (with or without fever) at any time while you are taking ceritinib, contact your doctor immediately.
Pancreatitis: Ceritinib can cause the pancreas to become inflamed. If you have a history of pancreatitis, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Report signs of pancreatitis such as abdominal pain on the upper left side, back pain, nausea, fever, chills, rapid heartbeat, or swollen abdomen to your doctor immediately.
If you have a history of pancreatitis, gallstones, alcoholism, or high triglycerides, you may be more at risk of experiencing this.
Unwanted effects of this medication: Nausea, vomiting, and diarrhea are commonly experienced by people using this medication. If they are severe, talk to your doctor or pharmacist about medications that can be used to control these symptoms.
Pregnancy: The safety of this medication if used during pregnancy has not been determined. This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if ceritinib passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children.
