What might I experience while receiving ELZONRIS?

When you are treated with ELZONRIS for your BPDCN, you may experience side effects. Be sure to speak with members of your healthcare team about how you feel while taking ELZONRIS, as they may be able to help.

ELZONRIS can cause fluid to leak from small blood vessels into your body's tissues. This is called “Capillary Leak Syndrome”

  • fast weight gain
  • swelling of your face, arms, hands, legs, or feet
  • shortness of breath or difficulty breathing
