What is in this leaflet

All medicines have risks and benefits. Your doctor has weighed the risks of you being given IMBRUVICA against the benefits this medicine is expected to have for you.

What IMBRUVICA is used for

IMBRUVICA is an anticancer medicine that contains the active substance ibrutinib.

IMBRUVICA is used to treat the following blood cancers in adults:

Mantle Cell Lymphoma (MCL), a type of cancer affecting the lymph nodes;

Chronic Lymphocytic Leukaemia (CLL), including Small Lymphocytic Lymphoma (SLL), a type of cancer affecting a type of white blood cell called lymphocytes that also involve the lymph nodes.

Waldenström's macroglobulinemia (WM), a very rare cancer affecting the lymphocytes

IMBRUVICA works by blocking a protein in the body that helps cancer cells live and grow. This protein is called Bruton's tyrosine kinase. By blocking this protein, IMBRUVICA may help kill and reduce the number of cancer cells and may also slow the spread of the cancer.

Ask your doctor or healthcare professional if you have any questions about why IMBRUVICA has been prescribed for you.

This medicine is available only with a doctor's prescription.

Taking IMBRUVICA

Always take IMBRUVICA exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

Laboratory tests may show that your blood count contains more white blood cells (called "lymphocytes"), in the first few weeks of treatment. This is expected and may last for a few months. This does not necessarily mean that your blood cancer is getting worse. Your doctor will check your blood counts before or during the treatment and in rare cases they may need to give you another medicine. Talk to your doctor about what your test results mean.

The recommended dose of IMBRUVICA for:

MCL is four 140 mg capsules once a day.

WM and CLL is three 140 mg capsules once a day.

Instructions:

Do not take IMBRUVICA with grapefruit or Seville oranges - this includes eating them, drinking the juice, or taking supplements that might contain them. This is because they can increase the amount of IMBRUVICA in your blood.

How long to take

Take IMBRUVICA exactly as prescribed by your doctor or healthcare professional. Do not change your dose or stop taking IMBRUVICA until your doctor tells you to.

What do I do if I forget to take IMBRUVICA?
