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
