Uses

This medication is used to treat certain cancers (such as chronic lymphocytic leukemia/small lymphocytic lymphoma, Waldenstrom's macroglobulinemia). Ibrutinib belongs to a class of drugs known as kinase inhibitors. It works by slowing or stopping the growth of cancer cells.

Ibrutinib is also used to treat a certain problem that may occur after a stem cell transplant (chronic graft versus host disease). It works by weakening your body's defense system (immune system).

How to use

Read the Patient Information Leaflet if available from your pharmacist before you start taking ibrutinib and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with a full glass of water (8 ounces or 240 milliliters) as directed by your doctor, usually once daily. Swallow the capsules and tablets whole. Do not open, break, or chew the capsules. Do not cut, crush, or chew the tablets. Drink plenty of fluids while taking ibrutinib unless otherwise directed by your doctor.

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

Do not increase your dose or take this medication more often than prescribed. Your condition will not improve any faster, and your risk of serious side effects will increase.

Avoid eating grapefruit or drinking grapefruit juice while using this medication unless your doctor or pharmacist says you may do so safely. Also avoid eating Seville oranges (often found in marmalade). Grapefruit and Seville oranges can increase the chance of side effects with this medicine. Ask your doctor or pharmacist for more details.
