Rituxirel 500 mg Injection is formulated with rituximab as its active ingredient. Rituximab belongs to a group of medicines called monoclonal antibodies. It works by targeting specific B cells in the immune system and may be used to treat certain blood cancers and autoimmune conditions.
The injection is available in a 500 mg/50 mL strength and is administered through an intravenous (IV) infusion by a qualified healthcare professional. Rituxirel treatment requires careful medical monitoring because it may cause infusion-related reactions or increase the risk of infections.
It may also cause serious complications, such as hepatitis B reactivation, in people with a previous hepatitis B infection. Your healthcare professional will monitor you during treatment and determine the appropriate dose and treatment schedule based on your medical condition.
What is Rituxirel 500 mg Injection?
Rituxirel 500 mg Injection is a prescription medicine that contains rituximab 500 mg as its active ingredient. It belongs to a group of medicines called anti-CD20 monoclonal antibodies. Rituximab works by targeting certain B cells in the immune system that carry a protein called CD20.
Rituxirel 500mg Injection is used to treat certain blood cancers and autoimmune conditions, including non-Hodgkin’s lymphoma, chronic lymphocytic leukemia, rheumatoid arthritis, granulomatosis with polyangiitis, microscopic polyangiitis, and pemphigus vulgaris, depending on the prescribed treatment plan.
Rituxirel 500 mg Injection is manufactured by Reliance Life Sciences. Since it can affect the immune system, it should be given by a qualified healthcare professional under proper medical supervision.
How Does Rituxirel 500 mg Injection Work?
Rituxirel 500 mg Injection works by targeting CD20, a protein present on certain B lymphocytes. After rituximab attaches to CD20, it helps the immune system identify and remove these targeted B cells. B cells are part of the immune system, but abnormal or overactive B cells can play a role in certain blood cancers and autoimmune conditions. By reducing these B cells, rituximab can help control abnormal cancer-related or immune-system activity in certain conditions.
This action can help manage conditions for which rituximab is prescribed, such as certain types of lymphoma and autoimmune disorders. The response to treatment can vary from person to person. Rituxirel should therefore be used according to the treatment plan prescribed for the particular condition.

- Chronic Lymphocytic Leukemia (CLL): Used to treat a type of blood cancer that affects certain white blood cells.
- Rheumatoid Arthritis: May be used with other medicines in adults with moderate-to-severe rheumatoid arthritis.
- Granulomatosis with Polyangiitis (GPA): Used for an autoimmune condition that causes inflammation in blood vessels.

How is Rituxirel 500 mg Injection Given?
Rituxirel 500 mg Injection is given through a slow intravenous (IV) infusion into a vein. It should not be injected or used by yourself. A doctor or trained medical team gives the infusion in a hospital or clinic.
Before starting the infusion, other medicines may be given to help reduce the chance of infusion-related reactions. During the infusion, you may be closely monitored for fever, chills, rash, changes in blood pressure, breathing problems, or other reactions.
Rituximab should be given as an IV infusion and not as a quick injection. If a reaction occurs, the infusion may be slowed or temporarily stopped until the symptoms are controlled. The medical team will then decide whether the infusion can be continued safely.
