Rituximab-abbs

Generic name: Rituximab-abbs

Usage of Rituximab-abbs

Rituximab-abbs injection is used alone or together with other cancer medicines to treat a type of cancer called non-Hodgkin's lymphoma (NHL). It helps the immune system destroy cancer cells. Rituximab-abbs is a monoclonal antibody.

Rituximab-abbs injection is used together with other cancer medicines (eg, fludarabine and cyclophosphamide) to treat chronic lymphocytic leukemia (CLL).

Rituximab-abbs injection is used together with methotrexate to treat the symptoms of moderate-to-severely-active rheumatoid arthritis. It helps to keep joint damage from getting worse after other medicines (eg, adalimumab, etanercept, or infliximab) did not work well. The use of rituximab-abbs injection in rheumatoid arthritis without previous treatment with these medicines is not recommended.

Rituximab-abbs injection is used together with steroids to treat granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA). These are immune disorders that cause blood vessels to be inflamed.

This medicine is to be given only by or under the direct supervision of your doctor.

Use an effective form of birth control to keep from getting pregnant during treatment with this medicine and for at least 12 months after the last dose. If you think you have become pregnant while receiving this medicine, tell your doctor right away.

    This medicine may cause infusion-related reactions, which can be life-threatening and require immediate medical attention. Tell your doctor right away if you start to have a fever, chills or shaking, dizziness, trouble breathing, itching or rash, lightheadedness or fainting after receiving this medicine.

    This medicine 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 receiving this medicine and the risk for 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 have a decrease or change in the amount of urine, 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.

    This medicine may increase your risk of developing infections (eg, viral, bacterial, or fungal) during or after treatment with this medicine. Avoid being near people who are sick or have infections while you are receiving this medicine. Wash your hands often.

    Non-live vaccines may be given at least 4 weeks before starting rituximab-abbs. However, do not have any immunizations (vaccinations) while you are being treated with rituximab-abbs and after you stop treatment with it, without your doctor's approval. Rituximab-abbs 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 (eg, 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.

    This medicine may cause heart and heart rhythm problems (eg, heart attack, arrhythmia, cardiogenic shock). Check with your doctor if you have chest pain or discomfort, pain or discomfort in the arms, jaw, back, or neck, dizziness, fainting, fast, slow, or irregular heartbeat, cool, sweaty skin, or trouble breathing.

These could be symptoms of a serious kidney problem.

    This medicine 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 this medicine.

    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.
