Uses For rituximab

Rituximab injection is a monoclonal antibody. It is used to treat a type of cancer called non-Hodgkin's lymphoma. It can be used alone or with other cancer medicines (chemotherapy).

Rituximab may also be used in combination with methotrexate to reduce the signs and symptoms of rheumatoid arthritis and help keep joint damage from getting worse after at least one other medicine (e.g., adalimumab, etanercept, infliximab) has been used and did not work well.

rituximab is to be administered only by or under the immediate supervision of your doctor.

Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, rituximab is used in certain patients with the following medical conditions:

  • Chronic lymphocytic leukemia (cancer of the blood and lymph system).
  • Immune or idiopathic thrombocytopenic purpura (ITP) (a blood disease).
  • Waldenstrom's macroglobulinemia (cancer of the blood).

Before Using rituximab

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For rituximab, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to rituximab or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of rituximab in the pediatric population. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of rituximab in the elderly. However, elderly patients are more likely to have age-related heart and lung problems, which may require caution in patients receiving rituximab.

Pregnancy

  • Angina (chest pain), history of or
  • Heart disease or
  • Heart rhythm problems (e.g., arrhythmia), history of or

Proper Use of rituximab

You will receive rituximab while you are in a hospital or cancer treatment center. A nurse or other trained health professional will give you rituximab. rituximab is given through a needle placed in one of your veins.

Rituximab must be given slowly, so the needle will remain in place for a few hours. You may also receive medicines to help prevent possible allergic reactions to the injection.

rituximab should come with a medication guide. Read and follow these instructions carefully. Ask your doctor if you have any questions.

Precautions While Using rituximab

It is very important that your doctor check your progress at regular visits to make sure that rituximab is working properly. Blood tests may be needed to check for unwanted effects.

rituximab may increase your risk of developing infections. Avoid being near people who are sick or have infections while you are using rituximab. Wash your hands often. Tell your doctor if you have lupus or if you have any kind of infection before you start using rituximab. Also tell your doctor if you have ever had an infection that would not go away or an infection that kept coming back.

rituximab may cause a rare and serious brain infection called progressive multifocal leukoencephalopathy (PML). The risk for getting this infection is higher if you have rheumatoid arthritis. Talk to your doctor about the benefits of taking rituximab and the risk of this infection. Check with your doctor right away if you are having more than one of these symptoms: vision changes, loss of coordination, clumsiness, memory loss, difficulty speaking or understanding what others say, and weakness in the legs.

Call your doctor right away if you start to have a cough that won't go away, weight loss, night sweats, fever, chills, or flu-like symptoms, such as a runny or stuffy nose, headache, blurred vision, or feeling generally ill. These may be signs that you have an infection.

While you are being treated with rituximab, and after you stop treatment with it, do not have any immunizations (vaccinations) without your doctor's approval. If you have rheumatoid arthritis, non-live virus vaccines should be given at least 4 weeks before receiving rituximab. Rituximab may lower your body's resistance, and there is a chance you might get the infection the immunization is meant to prevent. In addition, other persons living in your household should not get live vaccines (e.g., nasal flu virus vaccine). Try to avoid persons who have taken live vaccines. Do not get close to them and do not stay in the same room with them for very long. If you cannot take these precautions, you should wear a protective face mask that covers the nose and mouth.

Rituximab may cause chest pain, fever, chills, itching, hives, flushing of the face, rash, troubled breathing, or swelling of the face, tongue, and throat within a few hours after you receive it. Check with your doctor or nurse right away if you have any of these symptoms.

rituximab may cause a serious type of reaction called tumor lysis syndrome (TLS). Your doctor may give you a medicine to help prevent this. Call your doctor right away if you have a decrease or change in urine amount; joint pain, stiffness, or swelling; lower back, side, or stomach pain; a rapid weight gain; swelling of the feet or lower legs; or unusual tiredness or weakness.

Serious skin reactions can occur during treatment with rituximab. Stop using rituximab and check with your doctor right away if you have any of the following symptoms while using rituximab: blistering, peeling, or loosening of the skin; red, swollen, irritated, or scaly skin; skin peeling or fissures; fingernail changes; or fever or chills.

Check with your doctor immediately if you have any symptoms of liver problems including skin and eyes turning yellow, dark brown-colored urine, right-sided abdominal or stomach pain, fever, or severe tiredness.

rituximab may cause serious stomach and bowel problems, especially when used with other cancer medicines. Check with your doctor right away if you start having stomach pain while being treated with rituximab.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
