Leukemia Home > What Is Rituxan?

If you have rheumatoid arthritis or certain types of cancer, your healthcare provider may prescribe Rituxan® (rituximab). But what is it?
Specifically, this prescription medication is approved to treat the following conditions:


A healthcare provider will administer Rituxan intravenously via an IV infusion (also known as an "IV drip") that will last for several hours. The time between doses will vary, depending on the particular dosing regimen.
This medication works by binding to the surface of certain cells, which signals the body to destroy them. Although most people tolerate this medication well, side effects are possible and may include fever, chills, and infections.
