Ristova (Rituximab)belongs to a group of cancer drugs known as monoclonal antibodies|.
Monoclonal antibodies recognise and lock onto specific proteins on the surface of cancer cells. This helps the body's immune system to recognise the cancer cells and destroy them. Monoclonal antibodies are sometimes called targeted therapies because they target cancer cells.
How Ristova (Rituximab) works
Ristova (Rituximab) locks onto a protein called CD20, which is found on the surface of white blood cells called B-lymphocytes or B-cells. This triggers the body’s immune system to attack the cells and destroy them.
As well as being found on the surface of normal B-cells, CD20 is also present on most of the abnormal B-cells which occur in many types of non‑Hodgkin lymphoma and on some of the abnormal B-cells found in CLL.
Ristova (Rituximab) destroys both abnormal (malignant) and normal B-cells. However, the body can replace normal B-cells that are damaged so their numbers recover once treatment is over.
When it is used
Ristova (Rituximab) is used to treat several types of non‑Hodgkin lymphoma. It may also be used to treat chronic lymphocytic leukaemia. It is often given in combination with chemotherapy| but may be given on its own.
Ristova (Rituximab)may also be given to people with follicular lymphoma| who have no signs of cancer at the end of their treatment (remission). The aim is to keep the lymphoma away for as long as possible.This is called maintenance therapy and is given every three months, for up to two years.
What it looks like
Ristova (Rituximab)forms a colourless fluid after being diluted.
How it is given
Ristova (Rituximab)is given as a drip into a vein (intravenous infusion). It may be given on its own or with chemotherapy.
Some people have an allergic reaction to rituximab. Reactions are most common with the first infusion so, to reduce the risk of a reaction, the first dose is given slowly over a number of hours. You will be given medicines before the treatment that help to prevent or reduce any reaction.
If you have a reaction, the infusion can be stopped and started again when the symptoms are over. You may need to stay in hospital overnight for the first treatment so that you can be monitored. After that, Ristova (Rituximab)can usually be given in the outpatients department and over a shorter period of time.
When used by itself, Ristova (Rituximab)is usually given weekly over a period of four weeks. The treatment may be repeated later if necessary.
If Ristova (Rituximab)is used with chemotherapy, it is given with each course of treatment.
Possible side effects
Each person’s reaction to cancer treatment is different. Some people have very few side effects, while others may experience more. The side effects described here won't affect everyone.
We have outlined the most common side effects but haven't included those that are rare and therefore unlikely to affect you. If you notice any effects which aren't listed here, discuss them with your doctor or specialist nurse.
The side effects of Ristova (Rituximab)are generally mild and some of these can be reduced with medicines.
Side effects of Ristova (Rituximab)fall into two groups:
These are most common with first few infusions. Reactions are usually mild or moderate but sometimes they can be more severe.
If you have a reaction it can usually be treated by slowing or stopping the drip until you feel better. You may also be given treatment such as an antihistamine or paracetamol. When you feel better the infusion can be continued. These reactions are less likely to happen after the second infusion.
You’ll be monitored closely during your infusion but it's very important to tell your nurse or doctor if you feel unwell or have any of the following symptoms:
Sometimes an infusion-related reaction can happen a few hours after treatment. If you develop these symptoms or feel unwell after you get home, contact the hospital straight away for advice.
Low blood pressure Some people have a fall in their blood pressure during the infusion. Your blood pressure will be checked regularly. If you normally take medicines to lower your blood pressure tell the doctor. You may be given instructions about when it's best to take these before Ristova (Rituximab) is given.
Tumour pain Some people experience mild pain in the parts of the body where they have cancer during the infusion. Painkillers| can be given to relieve this.
Lowered resistance to infection (neutropenia) Ristova (Rituximab)can reduce the number of white blood cells produced by the bone marrow, making you more prone to infection|. Your blood cell numbers (blood count) will be monitored throughout your treatment.
