Consumer Medicine Information

NOTICE: This Consumer Medicine Information (CMI) is intended for persons living in Australia. This page contains answers to some common questions about Mabthera SC (NHL). It does not contain all the information that is known about Mabthera SC (NHL). It does not take the place of talking to your doctor or pharmacist. All medicines have risks and benefits.

What MabThera SC is used for

MabThera SC contains the active ingredient rituximab.
MabThera SC belongs to a group of medicines known as anti-cancer agents. There are many different classes of anti-cancer agents. MabThera SC belongs to a class called monoclonal antibodies.
Monoclonal antibodies are proteins which specifically recognise and bind to other unique proteins in the body.
MabThera SC is used to treat non-Hodgkin's lymphoma.
MabThera SC 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. MabThera SC 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 SC after the initial course of treatment.
Your doctor may have prescribed MabThera SC for another reason.
Ask your doctor if you have any questions why MabThera SC has been prescribed for you.
This medicine is available only with a doctor's prescription.

Before you are given MabThera SC

When you must not be given MabThera SC

Do not use MabThera SC:
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 SC, talk to your doctor.

Before you are given MabThera SC

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

4.you are taking medicine to control blood pressure

MabThera SC may cause a reduction in blood pressure at the beginning of treatment. Because MabThera SC 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 SC.

5.you have pre-existing lung disease

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

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 SC or in the months after you receive MabThera SC. Your doctor will check if you should have any vaccines before you receive MabThera SC.

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 SC is harmful to an unborn baby. It is not recommended that you are given MabThera SC 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 SC.

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

It is not known if MabThera SC passes into breast milk. It is recommended that you discontinue breast feeding while you are treated with MabThera SC.
If you have not told your doctor about any of the above, tell them before you are given MabThera SC.

Use in children

The safety and effectiveness of MabThera SC 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 SC 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 SC.
It is not known if MabThera SC will affect your normal response to a vaccine.
It is possible that after treatment with MabThera SC 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 SC.

How MabThera SC is given

Your treatment with MabThera SC will always begin with an infusion of MabThera intravenous formulation into a vein. If the infusion is tolerated, then further treatment with MabThera SC can be given by subcutaneous injection. This means it is injected with a short needle into the fatty tissue just under the skin.
MabThera SC is given as a fixed dose of 1400 mg per injection. The injection occurs over approximately 5 minutes.
Your doctor will decide on the frequency of injections.
MabThera SC may be given with or without chemotherapy. When given in combination with chemotherapy, the standard treatment with MabThera SC consists of 1 subcutaneous injection on day 1 of each chemotherapy cycle.
MabThera SC must always be administered by a healthcare professional.
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 SC. You may receive MabThera SC once every 3 months for up to 2 years.

Overdose

As MabThera SC 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 SC, tell your doctor immediately.
