Understanding Possible Side Effects of IMBRUVICA® (ibrutinib)
IMBRUVICA® may cause serious side effects, including bleeding problems (hemorrhage), infections, decrease in blood cell counts, heart rhythm problems (ventricular arrhythmias, atrial fibrillation and atrial flutter), high blood pressure (hypertension), second primary cancers, and tumor lysis syndrome (TLS)*.1
*TLS is a disorder caused by the breakdown products of cancer cells, which can lead to kidney failure and other abnormalities.
The most common side effects in the mantle cell lymphoma (MCL) clinical trial were1:
- Low blood platelet count
- Low white blood cell count
- Shortness of breath
- Low red blood cell count
- Muscle and bone pain
- Stomach (abdomen) pain
- Swelling of legs and feet
- Upper respiratory tract infection
- Decreased appetite
In the MCL clinical trial, 9% of patients stopped taking IMBRUVICA® because of side effects. Also in the clinical trial, 14% of patients had their dosage of the drug reduced due to side effects.1
This is not a complete list of side effects. Others may occur. Tell your doctor if you think you are experiencing side effects.
If you are having some side effects, your doctor may tell you to lower your dose or to stop taking IMBRUVICA®. That’s one reason it’s so important to tell your healthcare team about side effects at any point in your treatment.1
