IDA is highly prevalent in subjects with gastrointestinal diseases and cancer, menstruating or pregnant women, and subjects who have undergone bariatric procedure. IDA can have a substantial medical and quality of life (QoL) burden on the subjects and the treatment of these subjects includes controlling the bleeding and replenishing lost iron. Oral iron administration is often used in the clinical practice at many clinics; however, oral iron may not be tolerated by all subjects. Hence, there is a need for an alternative iron treatment in subjects, who do not tolerate oral iron.
