Rituxan Hycela is used to treat certain types of lymphoma, a cancer that affects the white blood cells, and chronic lymphocytic leukemia.
Rituxan Hycela Overview
Rituxan Hycela is a prescription medication used to treat certain types of non-Hodgkin's lymphoma, (a type of cancer that begins in a type of white blood cells that normally fights infection) and chronic lymphocytic leukemia (a type of cancer that begins in the white blood cells) in adults.
It is a single product containing 2 medications: rituximab and hyaluronidase. Rituximab belongs to a group of drugs called monoclonal antibodies. These work by killing cancer cells and blocking activation of the immune system. Hyaluronidase is an enzyme that allows connective tissue penetration by hydralizing hyaluronic acid.
This medication is available in an injectable form to be given subcutaneously (under the skin) in the stomach area by a healthcare professional.
Common side effects of Rituxan Hycela include infections, neutropenia (an abnormally low count of a certain type of white blood cells), and nausea.
