Why is this medication prescribed?

A specific kind of non-small cell lung cancer (NSCLC) that has spread to the body is treated with ceritinib. The drug ceritinib belongs to the group of drugs known as kinase inhibitors. It functions by preventing the action of a problematic protein that instructs cancer cells to proliferate. This aids in containing or halting the spread of cancer cells.

How should this medicine be used?

Ceritinib is available as a tablet and a capsule for oral consumption. Once a day, it is often taken with food. Ceritinib should be taken every day at about the same time. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Just as prescribed, take ceritinib. Never take it in larger or less amounts or more frequently than directed by your doctor.

Never take more ceritinib if you vomit after taking it. Maintain your usual dosage routine.

Throughout your therapy, your doctor may tell you to stop taking ceritinib for a while, reduce your ceritinib dosage, treat you with additional medications, or do all three. The effectiveness of the medication for you and any adverse effects you may encounter will determine this. While you receive ceritinib treatment, be sure to discuss your feelings with your doctor.

What should I know about storage and disposal of this medication?

Keep this medication tightly closed in the original container and out of the reach of children. Keep it away from light, excessive heat, and moisture at room temperature (not in the bathroom).

Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilising a medicine take-back programme is the easiest approach to get rid of your medication. To find out about take-back programmes in your area, speak with your pharmacist or the garbage/recycling department in your city. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medications website at for additional information.

Although many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning.

What other information should I know?

Keep all of your appointments with your physician and the lab. To monitor how your body is responding to ceritinib, your doctor will request a number of lab tests. Before you start your treatment, your doctor will also request a lab test to determine whether ceritinib can treat your cancer.

No one else should take your medication. Any queries you may have regarding medication refills should be directed to your pharmacist.

You should keep a written record of every medication you take, including any over-the-counter (OTC) items, prescription drugs, and dietary supplements like vitamins and minerals. This list should be brought with you whenever you see a doctor or are admitted to the hospital. You should always have this information with you in case of emergencies.
