During and After Treatment


What to Expect During and After Treatment with DARZALEX®

During the Infusion

During your infusion, stay mindful of how you feel. It's important to get medical help right away if you get any of the symptoms listed below, which could mean you are having an infusion reaction.

Infusion reaction symptoms may include:
  • shortness of breath or trouble breathing
  • dizziness or lightheadedness (hypotension)
  • cough
  • wheezing
  • throat tightness
  • runny or stuffy nose
  • headache
  • itching
  • nausea
  • vomiting
  • chills
  • fever

Get medical help right away if you get any of these symptoms.

Infusion reactions are common with DARZALEX® and can be severe or serious. About half of people treated with DARZALEX® experienced an infusion reaction. These reactions are most likely to happen during the first infusion.

If you do have an infusion reaction, your healthcare professional may temporarily stop your infusion or completely stop treatment with DARZALEX®.


What Can I Expect After Treatment?

You will be given medicines (corticosteroids) by mouth to lower the chance of delayed infusion reactions. In addition, if you have a history of breathing problems, such as chronic obstructive pulmonary disease, you will be given additional medications that may help prevent these problems, such as bronchodilators or inhaled corticosteroids.

Be sure to discuss with your healthcare professional when you will receive infusions and to come in for all your infusions and follow-up appointments. If you miss any appointments, call your healthcare professional as soon as possible to reschedule your appointment.

Before and after each infusion of DARZALEX®, you will be given medicines that help to reduce the chance of an infusion reaction.
