Rituximab (Rituxan®)

Rituximab

Brand Name: Rituxan®

Rituximab is used for the treatment of non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia.

Rituximab is a biologic agent, also known as targeted therapy. More specifically, rituximab belongs in a class of medications called biologic antineoplastic agents. In NHL, it works by killing blood cells that have multiplied abnormally. For chronic lymphocytic leukemia, rituximab is combined with fludarabine and cyclophosphamide.

This medication comes as a liquid that is injected into a vein (intravenous). Usually, rituximab is given either once weekly for 4 – 8 weeks or on the first day of each chemotherapy cycle. The exact dosing schedule depends on several factors including how well your body tolerates treatment and what other medications you are taking. Your doctor will recommend the approach that is best for you.

Rituximab side effects

To prevent problematic interactions between rituximab and other drugs, be sure to tell your doctor if you are allergic to any medications, and what other medications and supplements you are currently taking. You should also inform your doctor if you have or ever had a liver tumor, liver kidney disease, hepatitis B, chicken pox, herpes, West Nile virus, cytomegalovirus, or any other infection, including infections that recur periodically. Also tell your doctor if you are pregnant or planning to become pregnant, or if you are breastfeeding. Rituximab should not be taken during breastfeeding.

Possible side effects may include:

  • Nausea
  • Vomiting
  • Diarrhea
  • Heartburn
  • Weight gain
  • Muscle or back pain
  • Flushing
  • Night sweats
  • Tiredness
  • Weakness
  • Numbness, burning, or tingling in the hands or feet
  • Runny nose

Some of rituximab’s side effects can be serious. Call your doctor immediately if you experience any of these symptoms:

  • Stomach area pain
  • Unusual bruising or bleeding
  • Sore throat, fever, chills, or other signs of infection
  • Chest tightness
  • Joint pain or soreness

Please note that this is not a comprehensive list. Patients may experience additional effects not mentioned above.

At Cancer Treatment Centers of America (CTCA), your team of cancer experts will explain each of the side effects of rituximab with you in detail, as well as the side effects and expectations of all other medications planned as part of your individualized treatment plan.
