Owing to questions regarding optimal iron formulation, dosage, route of administration, and safety, these complications are frequently overlooked and undertreated, negatively impacting patient development and quality of life.Purpose: To assess the safety and efficacy of iron sucrose (IS) and ferric carboxymaltose (FCM) in the treatment of ID and IDA in pediatric IBD.Methods: We retrospectively reviewed the medical records of pediatric patients with IBD treated for 10 years with IS (age &lt;14 years) or FCM (age \u226514 years) in a single regional referral center. The Ganzoni formula was used to calculate the iron dose administered. Adverse reactions were monitored during treatment and after discharge. Efficacy was defined as a \u22652 g\/dL rise in Hb or anemia resolution within 12 weeks after treatment in cases of IDA and transferrin saturation or ferritin normalization in cases of ID.Results: Sixty-three patients were treated with IV iron (41 with Crohn disease, 15 with ulcerative colitis, 7 with IBD-unclassified; median age, 14.6 years; 104 treatment courses [63 FCM, 41 IS during the 10-year study period]). Retreatment was necessary after a median 1.4 years in 26 patients (41.3%). The median activity scores of patients with recurrent ID indicated inactive disease. The treatment efficacy was 66.7% (FCM) and 67.6% (IS) in patients with IDA and 77.8% in patients with ID but without anemia. One adverse reaction (hypotension and rash) was associated with IS treatment.Conclusion: In one of the largest and longest follow-up cohorts, FCM and IS were safe and effective for correcting ID in pediatric patients with IBD. As ID recurs frequently, proactive screening and treatment are important.<\/jats:p>","DOI":"10.3345\/cep.2025.00640","type":"journal-article","created":{"date-parts":[[2025,6,10]],"date-time":"2025-06-10T01:53:21Z","timestamp":1749520401000},"page":"722-731","update-policy":"https:\/\/doi.org\/10.3345\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Treatment
