What Is Rituxan? 

Rituxan (rituximab) is a prescription medication administered for patients in all IVX Health centers via IV infusion. 

How Rituxan Works  

Rituxan works by targeting immune cells called B-cells. Overactive B-cells are believed to play a role in the symptoms and joint damage of rheumatoid arthritis. 

What Is Rituxan Used For?  

Doctors order rituximab to treat: 

Rituxan Infusion Dosage and Administration 

Patients receive rituximab intravenously. Treatment time for a Rituxan infusion at a medical clinic like IVX Health usually lasts 4-6 hours for the first treatment and 2-3 hours for the following treatments. 

Dosage and Frequency  

Rituxan is administered in “courses”. Each course consists of two 1-gram infusions given two weeks apart. The courses are separated by 6 months for a total of 4 infusions per year. 

Administering Rituxan via IV Infusion  

  1. The nurse prepares the patient’s arm by using rubbing alcohol to sterilize the location that is being used to insert the IV needle.
  2. Following needle insertion, the IV line is held in place with tape. 
  3. The nurse attaches the patient’s IV line to the line coming down from the bag of medication. 

Every half-an-hour, the patient’s nurse takes his or her vitals.
