Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about MabThera intravenous infusion. It does not contain all the available information.

It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you being given MabThera against the benefits they expect it will have for you.

If you have any concerns about being given this medicine, ask your doctor or pharmacist.

Keep this leaflet.

You may need to read it again.

What MabThera is used for

MabThera contains the active ingredient rituximab.

MabThera belongs to a group of medicines known as anti-cancer agents. There are many different classes of anti-cancer agents. MabThera belongs to a class called monoclonal antibodies.

Monoclonal antibodies are proteins which specifically recognise and bind to other unique proteins in the body.

MabThera is used to treat non-Hodgkin's lymphoma and chronic lymphocytic leukaemia.

MabThera works by binding to a protein on the surface of certain white blood cells known as B lymphocytes. During the process of binding to the protein, the abnormal growth of the B lymphocytes is stopped.

It is the abnormally growing B lymphocytes that are responsible for certain types of non-Hodgkin's lymphoma and chronic lymphocytic leukaemia.

MabThera may be used on its own or together with chemotherapy.

If your doctor thinks it is appropriate for your circumstances you may continue to receive MabThera after the initial course of treatment.

Your doctor may have prescribed MabThera for another reason.

Ask your doctor if you have any questions why MabThera has been prescribed for you.

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

Before you are given MabThera

When you must not be given MabThera

Do not use MabThera:

if you have had an allergic reaction to rituximab or any of the ingredients listed at the end of this leaflet

if you have had an allergic reaction to any other proteins that are of mouse origin

Some of the symptoms of an allergic reaction may include severe skin rash, itching, hives, swelling of the face, lips, mouth or throat which may cause difficulty in swallowing or breathing, swelling of the hands, feet or ankles.

If you are not sure if you should start receiving MabThera, talk to your doctor.

Before you are given MabThera

Your doctor must know about all the following before you are given MabThera.

Tell your doctor if:

1.you have an infection, or a history of a recurring or long-term infection such as hepatitis B

2.you are taking or have previously taken medicines which may affect your immune system, such as chemotherapy or immunosuppressive medicines

If you are taking or have taken medicines which affect your immune system, you may have an increased risk of infections. There have been reports of a rare, serious brain infection called PML (progressive multifocal leuko-encephalopathy) usually affecting people with a weakened immune system. Your chance of getting PML may be higher if you are treated with MabThera and/or other medicines that weaken the immune system. PML can cause severe disability or even death.

3.you have a history of heart disease with:

angina

cardiac arrhythmias (abnormal beating of the heart)

congestive heart failure

Your doctor will supervise you closely during treatment with MabThera.

4.you are taking medicine to control blood pressure

MabThera may cause a reduction in blood pressure at the beginning of treatment. Because MabThera may cause a temporary drop in your blood pressure, your doctor may advise you to temporarily stop taking your blood pressure medicine before you are given MabThera.

5.you have pre-existing lung disease

You may have a greater chance of breathing difficulties during treatment with MabThera.

6.you intend to have or have had immunisation with any vaccine (e.g. measles, rubella, flu, vaccines for travel purposes)

Some vaccines should not be given at the same time as MabThera or in the months after you receive MabThera. Your doctor will check if you should have any vaccines before you receive MabThera.

7.you are allergic to any other medicines or any other substances such as foods, preservatives or dyes

8.you are pregnant or intend to become pregnant

It is not known whether MabThera is harmful to an unborn baby. It is not recommended that you are given MabThera while you are pregnant.

If you are a woman of child bearing potential, you must use effective contraceptive methods to prevent pregnancy during treatment and for 12 months after completing treatment with MabThera.

9.you are breast feeding or plan to breast feed.

It is not known if MabThera passes into breast milk. It is recommended that you discontinue breast feeding while you are treated with MabThera.

If you have not told your doctor about any of the above, tell them before you are given MabThera.

Use in children

The safety and effectiveness of MabThera have not been established in children.

Taking other medicines

Tell your doctor if you are taking any other medicines including any that you have bought without a prescription from a pharmacy, supermarket or healthfood shop.

As MabThera may cause a temporary drop in your blood pressure at the beginning of treatment, your doctor may advise you to temporarily stop taking your blood pressure medicine before you are given MabThera.

It is not known if MabThera will affect your normal response to a vaccine.

It is possible that after treatment with MabThera you may experience allergic reactions if you are treated with other medications containing monoclonal antibodies.

Your doctor and pharmacist will have more information on medicines to be careful with or to avoid while undergoing treatment with MabThera.

How MabThera is given

MabThera is given by slow infusion into a vein (intravenous infusion) by a healthcare professional.

Your doctor will decide what dose and how long you will receive MabThera. The dose of MabThera depends on your body weight and body height.

MabThera may be given with or without chemotherapy. When given in combination with chemotherapy, the standard treatment with MabThera consists of 1 infusion on day 1 of each chemotherapy cycle.

Depending on the circumstances of your disease or response to the drug your doctor may decide to change your treatment.

Maintenance treatment

If you respond to initial treatment your doctor may decide to continue your treatment with MabThera for up to 2 years.

Overdose

As MabThera is given to you under the supervision of your doctor, it is very unlikely that you will receive too much. However, if you experience any side effects after being given MabThera, tell your doctor immediately.

While you are receiving MabThera

Things you must do

If you are a woman of child bearing potential, you must use effective contraceptive methods to prevent pregnancy during treatment with MabThera and for 12 months after completing treatment.
