Daratumumab is a prescription medicinal product used to treat patients with a type of blood cancer called multiple myeloma (MM). The daratumumab treatment is not chemotherapy, rather a targeted monoclonal antibody that helps resist or inhibit the progression of MM in several ways. Daratumumab may be administered alone or along with other medications. This medicine will be administered by your health specialist by intravenous (IV) infusion into the vein. In case you miss any appointments, call your health specialist as promptly as possible in order to reschedule your appointment.
