1. What MabThera is and what it is used for
What MabThera is
MabThera contains the active substance “rituximab”. This is a type of protein called a “monoclonal antibody”. It sticks to the surface of a type of white blood cell called “B-Lymphocyte”. When rituximab sticks to the surface of this cell, the cell dies.
MabThera is available as a medicine given as a drip (called MabThera 100 mg or MabThera 500 mg, concentrate for solution for infusion) and as a medicine for injection under your skin (called MabThera 1400 mg or MabThera 1600 mg, solution for subcutaneous injection).
What MabThera is used for
MabThera 1400 mg is used to treat Non-Hodgkin’s lymphoma in adults.
- This is a disease of the lymph tissue (part of the immune system) that affects a type of white blood cell called B-Lymphocytes.
MabThera 1400 mg can be given alone or with other medicines called “chemotherapy”.
You will always be given MabThera as a drip (intra-venous infusion) at the start of your treatment.
After this, you will be given MabThera as an injection under your skin. Your doctor will decide when to start MabThera injections.
In patients where the treatment is working, MabThera may be used as a maintenance treatment for 2 years after completing the initial treatment.
2 What you need to know before you are given MabThera
Do not have MabThera if:
- you are allergic to rituximab, other proteins which are like rituximab, or any of the other ingredients of this medicine (listed in section 6)
- you are allergic to hyaluronidase (an enzyme that helps to increase the absorption of injected active substance)
- you have a severe active infection at the moment
- you have a weak immune system.
Do not have MabThera if any of the above apply to you. If you are not sure, talk to your doctor, pharmacist or nurse before you are given MabThera.
Warnings and precautions
Talk to your doctor, pharmacist or nurse before you are given MabThera if:
- you have ever had or might now have a hepatitis infection. This is because in a few cases, MabThera could cause hepatitis B to become active again, which can be fatal in very rare cases. Patients who have ever had hepatitis B infection will be carefully checked by their doctor for signs of this infection
- you have ever had heart problems (such as angina, palpitations or heart failure) or breathing problems.
If any of the above apply to you (or you are not sure), talk to your doctor, pharmacist or nurse before you are given MabThera. Your doctor may need to take special care of you during your treatment with MabThera.
Also talk to your doctor if you think you may need any vaccinations in the near future, including vaccinations needed to travel to other countries. 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.
Children and adolescents
Talk to your doctor, pharmacist or nurse before you are given this medicine if you, or your child, are under 18 years of age. This is because there is not much information about the use of MabThera in children and adolescents.
Other medicines and MabThera
Tell your doctor, pharmacist or nurse if you are taking, have recently taken or might take any other medicines. This includes medicines obtained without a prescription and herbal medicines. This is because MabThera can affect the way some other medicines work. Also some other medicines can affect the way MabThera works.
In particular, tell your doctor:
- if you are taking medicines for high blood pressure. You may be asked not to take these other medicines 12 hours before you are given MabThera. This is because some people have a fall in their blood pressure while they are being given MabThera
- if you have ever taken medicines which affect your immune system – such as chemotherapy or immune-suppressive medicines.
If any of the above apply to you (or you are not sure), talk to your doctor, pharmacist or nurse before you are given MabThera.
Pregnancy and breast-feeding
You must tell your doctor or nurse if you are pregnant, think that you might be pregnant or are planning to become pregnant. This is because MabThera can cross the placenta and may affect your baby.
If you can get pregnant, you and your partner must use an effective method of contraception while using MabThera. You must also do this for 12 months after your last treatment with MabThera.
MabThera passes into breast milk in small amounts. As the long-term effects on breastfed infants are not known, breastfeeding is not recommended during treatment with MabThera and for 12 months after the treatment.
Driving and using machines
It is not known whether MabThera has an effect on you being able to drive or use any tools or machines.
MabThera 1400 mg contains less than 1 mmol sodium (main component of the cooking/table salt) per dose, i.e. it is essentially sodium-free.
3 How MabThera is given
How it is given
MabThera will be given to you by a doctor or nurse who is experienced in the use of this treatment.
They will watch you closely while you are being given this medicine. This is in case you get any side effects.
You will always be given MabThera as a drip (intra-venous infusion) at the start of your treatment.
After this, you will be given MabThera as an injection under your skin (subcutaneous injection) over approximately 5 minutes. There is a peel-off sticker on the glass vial that specifies the medication.
Your doctor or nurse will place the sticker on the syringe before injection.
Your doctor will decide when to start MabThera injections.
When injected under your skin, it is given in the stomach area, not in other sites of the body, and not into areas of the stomach where the skin is red, bruised, tender, hard or where there are moles or scars.
Medicines given before each MabThera administration
Before you are given MabThera, you will be given other medicines (pre-medication) to prevent or reduce possible side effects.
How much and how often you will receive your treatment
- MabThera will be given to you on the same day as your chemotherapy. This is usually given every 3 weeks up to 8 times.
- If you respond well to treatment, you may be given MabThera as a maintenance treatment every 2 or 3 months for two years.
Your doctor may change this, depending on how you respond to the medicine.
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
