WARNING

Rituximab and Hyaluronidase Human Injection is a combination medication used for the treatment of certain conditions, such as non-Hodgkin’s lymphoma and chronic lymphocytic leukemia. It combines rituximab, a monoclonal antibody, with hyaluronidase, an enzyme that helps the dispersion and absorption of rituximab.

While Rituximab and Hyaluronidase Human Injection can be effective in treating specific medical conditions, it is essential to be aware of potential risks and side effects associated with the medication. It’s important to note that individual responses to the medication can vary, and not everyone will experience these side effects. Some potential risks include:

• Infusion Reactions: Rituximab can cause infusion reactions, which may include fever, chills, nausea, headache, and difficulty breathing. These reactions typically occur during the infusion and may require immediate medical attention.
• Infections: Rituximab can increase the risk of infections, including bacterial, viral, and fungal infections. Patients should be monitored for signs of infections, and precautions should be taken to reduce the risk of exposure.
• Hypersensitivity Reactions: Severe allergic reactions, including anaphylaxis, can occur with rituximab and hyaluronidase. Patients with known allergies to these medications or their components should not use them.
• Cardiac and Pulmonary Effects: There have been reports of serious cardiac and pulmonary reactions, including heart and lung problems. Patients with pre-existing cardiac or pulmonary conditions may be at a higher risk.
• Tumor Lysis Syndrome: In some cases, rituximab treatment can lead to tumor lysis syndrome, a condition characterized by the rapid breakdown of cancer cells, releasing their contents into the bloodstream. This can lead to metabolic imbalances and organ damage.
• Progressive Multifocal Leukoencephalopathy (PML): PML, a rare and serious brain infection, has been reported in patients receiving rituximab, particularly those with weakened immune systems.
• Bone Marrow Suppression: Rituximab may cause a decrease in blood cell counts, leading to conditions such as neutropenia, thrombocytopenia, and anemia.
