Zykadia (Ceritinib) – Oral

What Is Zykadia?

Zykadia (ceritinib) is an oral medication used to treat adults with non-small cell lung cancer (NSCLC). You are eligible for treatment with Zykadia if your cancer has metastasized (spread) to areas of the body outside of the lung, or has an anaplastic lymphoma kinase (ALK) mutation.

Zykadia is a kinase inhibitor. It works by blocking the action of a protein called ALK and other proteins found on cancer cells to stop these cells from multiplying.

This medication is available in tablet and capsule form.

What Is Zykadia Used For?

Zykadia is used to treat metastatic NSCLC with an ALK mutation.

An ALK mutation is found in about 4% of NSCLCs. To find this mutation, specialized genomic testing is done on the cancer cells. ALK mutations cause the cancer cells in NSCLC to grow quickly and out of control. Zykadia blocks the action of ALK, which stops these cells from proliferating.

How to Take Zykadia

Take Zykadia by mouth once a day with food. Swallow the capsules or tablets whole; do not break, crush, or chew them. Do not take Zykadia with grapefruit juice, which can affect how well the medication works in the body.

Because this medication can be harmful if used during pregnancy, females who are able to become pregnant should use reliable birth control during treatment and for six months after stopping. Males with female partners should use condoms during treatment and for three months afterward.


Store Zykadia in its original package at room temperature (between 68 and 77 degrees F). Do not store it in the bathroom. As with any medication, keep it out of reach of children and pets to prevent accidental consumption.

How Long Does Zykadia Take to Work?

The full benefit of the medication may not be known for a few months after starting it. Your oncologist will periodically do imaging tests to see how well the medication is working.

Frequently Asked Questions

  • What is Zykadia used for?

    Zykadia is used to treat metastatic non-small cell lung cancer (NSCLC) with an ALK mutation.

  • How does Zykadia work?

    Zykadia works by blocking the ALK pathway. This pathway is altered in ALK-mutated lung cancers and is used by cancer cells to grow abnormally. By blocking ALK, Zykadia slows cancer cell growth.

  • What drugs should not be taken with Zykadia?

    Some medications should not be used along with Zykadia. These medications include phenobarbital, ketoconazole, verapamil, and erythromycin.

  • What are the side effects of Zykadia?
