How to use

Read the Medication Guide and, if available, the Instructions for Use provided by your pharmacist before you start taking crizotinib and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with or without food as directed by your doctor, usually once or twice daily. This medication comes in 2 dosage forms: a capsule to swallow or a capsule that must be opened that contains pellets.

If you are using the capsules to swallow, swallow the capsule(s) whole. Do not chew, crush, or split the capsules.

If you are using the capsules that contain pellets, do not swallow the capsule(s) whole. You must first open the capsule(s), then directly pour or spoon all of the pellets into your mouth. Do not chew or crush the pellets before swallowing. Drink water after taking to make sure the entire dose is taken. Repeat these steps if the dose is for more than one capsule. Throw away the empty capsule shell(s) in the trash.

If you vomit after taking your dose of the medication, do not take an extra dose. Take the next dose of your medication at the regular time.

The dosage is based on your medical condition, lab tests, response to treatment, and other medications you may be taking. Children's dosage is also based on body size. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

To decrease the risk of side effects, your doctor may prescribe other medications to take along with this medication. Carefully follow your doctor's directions for all your medications.

Avoid eating grapefruit or drinking grapefruit juice while using this medication unless your doctor or pharmacist says you may do so safely. Grapefruit can increase the chance of side effects with this medicine. Ask your doctor or pharmacist for more details.

Do not increase your dose or use this drug more often or for longer than prescribed. Your condition will not improve any faster, and your risk of side effects will increase.

Use this medication regularly to get the most benefit from it. To help you remember, use it at the same time(s) each day.

Since this drug can be absorbed through the skin and lungs and may harm an unborn baby, women who are pregnant or who may become pregnant should not handle this medication or breathe the dust from the capsules.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Crizotinib may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.

The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using crizotinib, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions:

  • certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG)
  • family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death)

Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using crizotinib safely.

Crizotinib can make you more likely to get infections or may make current infections worse. Stay away from anyone who has an infection that may easily spread (such as chickenpox, COVID-19, measles, flu). Talk to your doctor if you have been exposed to an infection or for more details.

Tell your health care professional that you are using crizotinib before having any immunizations/vaccinations. Avoid contact with people who have recently received live vaccines (such as flu vaccine inhaled through the nose).

This drug may make you dizzy or cause vision changes. Alcohol or marijuana (cannabis) can make you more dizzy. Do not drive, use machinery, or do anything that needs alertness or clear vision until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).

This medication may make you more sensitive to the sun. Limit your time in the sun. Avoid tanning booths and sunlamps. Use sunscreen and wear protective clothing when outdoors. Tell your doctor right away if you get sunburned or have skin blisters/redness.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

Older adults may be more sensitive to the side effects of this drug, especially QT prolongation (see above).
