Target Hb 13 g/dL · Iron stores 500 mg

Suggested Regimens

Iron Sucrose: 7 sessions × 200 mg IV slow over 30 min, every 2-3 days. Lowest-cost option.

Ferric Carboxymaltose: 2 dose(s) × up to 1000 mg single infusion over 15-30 min. Premium option. Watch for hypophosphatemia.

Iron Isomaltoside (Monofer): 1 dose(s) — full deficit in single infusion up to 1500 mg over 30 min. Good safety profile.

Clinical Disclaimer: Always rule out blood loss, malabsorption (celiac, H. pylori) and chronic disease before attributing anemia to iron deficiency alone. IV iron requires monitored infusion — test dose for iron sucrose, watch for hypersensitivity with FCM. Always verify against your local prescribing reference and apply clinical judgment.
