Intravenous Ferric Carboxymaltose-Induced Hypophosphatemia in a Patient with Systemic Lupus Erythematosus: Case Report

Anemia is the most frequently observed hematological alteration in patients with systemic lupus erythematosus. Parenteral iron infusion is a highly effective treatment for the commonly encountered condition of iron deficiency. We report a case of an iron-deficient patient who developed severe symptoms due to hypophosphatemia following the administration of intravenous ferric carboxymaltose. These symptoms included feelings of dizziness and muscle cramping. The necessity to inform doctors and patients about this potential consequence has intensified. With this case report, we hope to raise awareness of the start of screening for this complication in the United Arab Emirates. Patients should also notify the doctor for follow-up if their fatigue worsens or if they develop any new musculoskeletal problems.
