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.
