Get medical help right away if you notice any signs of a serious allergic reaction, such as rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing, or chest pain. Your doctor may give you other medications to help with these side effects or may slow down or stop your treatment for some time.

Rarely, people using this medication have developed severe skin/kidney problems. Tell your doctor right away if you develop changes in skin color, change in the amount of urine, or pink/bloody urine.

Before starting treatment with this medication, tell your doctor if you have a history of heart problems (such as heart failure), breathing problems (such as fluid in the lungs), or swelling. These problems may get worse during the infusion. Your doctor or nurse may monitor you for longer periods after your infusion.
