After a Rituxan (rituximab) infusion you may experience certain side effects or adverse reactions that make you feel unwell. Rituxan affects different people in different ways, but the more common side effects include:

  • Fever (high temperature), muscle aches, headaches and chills, which are signs of infection.
  • Bruising and bleeding, including nosebleeds or bleeding gums, as well as tiny red spots on your limbs called petechiae. These are signs that the number of platelets in your blood may have dropped.
  • Fever, chills, nausea and vomiting, breathing difficulties and dizziness. These are signs of an allergic reaction. Allergic reactions are more common during your infusion, particularly your first one and medications can help to manage your symptoms. Allergy medications can make you dizzy or drowsy, so do not drive yourself home after your infusion.
  • Nausea and vomiting. You may feel sick or actually be sick because of your infusion. Anti-sickness medications, called antiemetics, can help to control your symptoms. Eating small meals and snacks, avoiding fatty and fried food, drinking plenty of water can also help.
