Mr. C, a 30-year-old male with Crohn's disease, presented to his clinician with symptoms of fatigue, lethargy, headaches, pallor, hair loss, irritability, and weakness. He states that these symptoms are significantly interfering with his productivity at work and with his family life at home.

Shortly after initiation of this therapy, he began feeling fatigued, and in the following weeks, he developed hair loss, irritability, and increasingly frequent headaches. His clinician initiated treatment with oral iron supplementation but his symptoms continued to worsen.
