Patient’s Leaflet

What is it and how is it used?

Zevalin is a kit for the preparation of the active substance ibritumomab tiuxetan [ 90Y], a monoclonal antibody labelled with the radioactive substance yttrium-90 ( 90Y). Zevalin attaches to a protein (CD20) on the surface of certain white blood cells (B-cells) and kills them by irradiation.

Zevalin is used to treat patients suffering from specific subgroups of B-cell non-Hodgkin?s lymphoma (CD20+ indolent or transformed B-cell NHL) if an earlier rituximab, another monoclonal antibody, treatment has not worked, or has stopped working (refractory or relapsed disease).

Zevalin is also used in previously untreated patients with follicular lymphoma. It is used as a consolidation therapy to improve the reduction in the number of lymphoma cells (remission) achieved with the initial chemotherapy regimen.


What do you have to consider before using it?

You must not be given Zevalin:
  • if you are allergic (hypersensitive) to any of the following: - ibritumomab tiuxetan, yttrium chloride or to any of the other ingredients of Zevalin (listed in section 6 ?What Zevalin contains?) - rituximab or other murine-derived proteins
  • if you are pregnant or breast-feeding (see also section ?pregnancy and breast feeding?).

Take special care with Zevalin In the following cases, Zevalin use is not recommended since its safety and efficacy have not been established more than a quarter of your bone marrow contains malignant abnormal cells. If you have had external beam radiation a type of radiotherapy to more than a quarter of your bone marrow. If you receive Zevalin alone and the number of your blood platelets is fewer than 100,000mm3If the number of your blood platelets is fewer than 150,000mm3 after chemotherapy

If the number of your white blood cells is fewer than 1,500mm3If you have had a bone marrow transplant or have received blood stem cells in the past.

If you have been treated with other proteins (especially mouse-derived) before Zevalin treatment, you may be more likely to have an allergic reaction. You may, therefore, need to be tested for special antibodies.

In addition, Zevalin is not recommended for the use in patients with non-Hodgkin?s lymphoma involving the brain and/or spinal cord as those patients were not included in clinical studies.


Zevalin is not recommended for use in children below age 18 since safety and efficacy have not been established.

Elderly patients:

Limited data in elderly patients (aged 65 years or over) are available. No overall differences in safety or efficacy were observed between these patients and younger patients.

Using other medicines

Please tell your doctor or pharmacist if you are using or have recently used any other medicines, including medicines obtained without a prescription.
In particular, your doctor will need to interrupt treatment with growth factors such as filgrastim for a period of three weeks before giving you Zevalin to two weeks after Zevalin treatment. If you are given Zevalin less than 4 months after chemotherapy containing the active substance fludarabine, you may have a higher risk of having a reduced number of blood cells. Please tell your doctor that you were given Zevalin if you are due for vaccination after using it.

Pregnancy and breast-feeding

Zevalin must not be used during pregnancy. Your doctor will perform tests to exclude pregnancy before you start the treatment. Women of child-bearing potential and male patients must use reliable contraception during treatment with Zevalin and for up to one year after stopping treatment. There is a potential risk that ionizing radiation by Zevalin could harm your ovaries and testicles. Please ask your doctor how this may affect you, especially if you are planning on having children in the future.

Women must not breast-feed during treatment and for 12 months following the treatment. .

Driving and using machines

Zevalin can affect your abilityto drive and use machines, as dizziness is a common side effect. Please be cautious until you are sure you are not affected.

Important information about some of the ingredients of Zevalin

This medicine contains up to 28 mg sodium per dose, depending on the radioactivity concentration. To be taken into consideration by patients on a controlled sodium diet.


How is it used?

Zevalin must be handled and administered by experienced professionals in a medical facility authorized to use radioactive medicines.

The dose of Zevalin depends on your body weight, blood platelet counts and what Zevalin is being used for (indication). The maximum dose must not exceed 1200 MBq (?megabecquerel?, a unit to measure radioactivity).

Zevalin is used with another medicine containing the active substance rituximab.

You will be given a total of 3 infusions in the course of two visits to a medical facility, 7 to 9 days apart.

  • On day 1 you will be given one rituximab infusion
  • On day 7, 8, or 9 you will be given one rituximab infusion, followed by one Zevalin infusion shortly afterwards (within 4 hours).
How much Zevalin is given
For consolidation therapy in patients with follicular lymphoma

- The usual dose is 15 MBq/kg body weight.

For therapy of patients with relapsed or refractory Non-Hodgkin?s lymphoma not responding to rituximab

- The usual dose is 11 or 15 MBq per kg body weight, depending on your blood platelet count.

Preparation of Zevalin

Zevalin is not used directly, but must be prepared by your healthcare professional first. The kit allows the coupling of antibody ibritumomab tiuxetan with the radioactive isotope yttrium 90Y (radiolabelling).

How Zevalin is given

Zevalin is given by intravenous infusion (drip into a vein) usually lasting about 10 minutes.

After you are given Zevalin

The amount of radiation that your body will be exposed to due to Zevalin is smaller than with radiotherapy. Most radioactivity will decay within the body, but a small part will be eliminated through your urine. Therefore, for one week after the Zevalin infusion you must wash your hands thoroughly each time after urinating.

After treatment your doctor will perform regular blood tests to check your platelet and white cell counts. These usually decrease around two months after start of treatment.

If your doctor plans to treat you with some other antibody after treatment with Zevalin, you will need to be tested for special antibodies. Your doctor will tell you if this applies to you.

If you have received more Zevalin than you should

Your doctor will treat you, as appropriate, if you have any particular ill effects. This may include discontinuation of Zevalin therapy and treatment with growth factors or your own stem cells.


What are possible side effects?

Like all medicines, Zevalin can cause side effects, although not everybody gets them.

Tell your doctor immediately if you notice symptoms of any of the following:
- infection: fever, chills
- blood poisoning (sepsis): fever and chills, changes in mental status, rapid breathing, increased heart rate, decreased urine output, low blood pressure, shock, problems with bleeding or clotting
- infections of the lung (pneumonia): breathing difficulties

Low counts of blood cells unusual bruising, more bleeding then usual after injury, fever, or if you feel unusually tired or breathless severe mucous membrane reactions, which may occur days or months after Zevalin andor rituximab administration. Your doctor will immediately stop the treatment. extravasation leakage of the infusion to the surrounding tissue pain, burning sensation, stinging or another reaction at the infusion site during administration. Your doctor will immediately stop the infusion and restart it using another vein. allergic hypersensitivity reactionsinfusion reactions symptoms for allergic reactions infusion reactions may be skin reactions, breathing difficulties, swelling, itching, flushing, chills, dizziness as potential sign for low blood pressure.
