RITUXAN therapy

Plan to spend some time at the infusion center

The first infusion of RITUXAN is given slowly.

Your first treatment may take 4 to 6 hours or more. If you have an infusion-related reaction, your infusion will be slowed or stopped.

Your next infusions should take less time.

Starting with the second treatment cycle, your infusions will generally take between 3 and 4 hours. Previously untreated follicular lymphoma and DLBCL patients who do not have a serious infusion-related reaction during initial treatment my be able to receive follow-up infusions that last only 90 minutes. Not all patients will be able to receive a faster infusion.
