Product Information:

 Type of medication: Darzalex is a monoclonal antibody (a type of targeted therapy) used mainly to treat multiple myeloma, a cancer of plasma cells in the bone marrow.

How it works: It targets a protein called CD38 on cancer cells, helping your immune system recognize and destroy them.

How It’s Taken:

• Pre-medications: Patients usually receive medicines to prevent allergic reactions, like antihistamines, steroids, or acetaminophen, before the infusion.

Warnings:

1. Infusion reactions: Can include fever, chills, nausea, shortness of breath, or low blood pressure. Usually happen during the first infusion.
