When and How to Take Rituxan

Some general considerations to keep in mind during treatment with Rituxan include the following:
  • This medication comes in injectable form. Your healthcare provider will administer it intravenously via an IV infusion (also known as an "IV drip") that will last for several hours. He or she will start the infusion slowly to help avoid reactions to the medication and will slowly increase the infusion rate as tolerated.
  • The time between doses will vary, depending on the particular dosing regimen.
  • You should be given medications before each dose of Rituxan to reduce the risk of infusion reactions. Usually, this will consist of acetaminophen (Tylenol®), an antihistamine, and sometimes a steroid.
  • Infusion reactions can sometimes be serious and may cause various side effects, such as:
    • Fever
    • Chills
    • Itching
    • Low blood pressure
    • Low oxygen levels
    • Difficulty breathing
    • Heart problems.
If anything seems abnormal during your infusion, let your healthcare provider know right away in case it is an infusion reaction.
  • For Rituxan to work properly, it must be taken as prescribed. Missing doses will decrease the medication's effectiveness.
