Monofer (Ferric Derisomaltose)

Monofer is used to treat iron deficiency anemia by providing intravenous iron to patients who cannot receive or absorb oral iron.

• Iron deficiency anemia in adults: restores hemoglobin levels and replenishes iron stores.
• Anemia of chronic kidney disease: improves iron availability for erythropoiesis in CKD patients.
• Anemia related to inflammatory bowel disease: corrects iron loss and malabsorption associated with IBD.
• Post‑operative or postpartum anemia: rapidly repletes iron after surgical blood loss or childbirth.

• Ferric derisomaltose is a stable iron‑carbohydrate complex that, after intravenous infusion through the bloodstream, is rapidly taken up by the reticuloendothelial system. Within macrophages the complex releases bioavailable iron in a controlled manner, avoiding free labile iron. The iron then binds to transferrin and is incorporated into hemoglobin and other iron‑dependent proteins, supporting erythropoiesis and cellular metabolism while bypassing gastrointestinal absorption.

Ferric derisomaltose may cause a range of adverse reactions, which are categorized by frequency and severity.

Common Side Effects

• Nausea: mild to moderate feeling of sickness.
• Headache: transient cranial discomfort.
• Injection site reactions: pain, erythema or swelling at the infusion site.
• Transient hypotension: temporary drop in blood pressure during or shortly after infusion.

Serious or Rare Side Effects

• Anaphylactic reaction: severe allergic response requiring immediate medical attention.
• Hypophosphatemia: significant drop in serum phosphate levels that may cause muscle weakness or cardiac issues.

When using Monofer, clinicians should observe several precautionary measures to ensure patient safety and product integrity.

• Assess iron status: confirm iron deficiency and evaluate ferritin and transferrin saturation before administration.
• Monitor for hypersensitivity: observe patients during infusion for signs of allergic reaction.
• Check renal function: adjust use in patients with severe renal impairment.
• Avoid rapid infusion: administer at recommended rate to reduce risk of hypotension.
• Pregnancy and lactation: use only if potential benefit justifies potential risk, as safety data are limited.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Ferric derisomaltose can interact with certain medicines, influencing iron availability or increasing adverse reaction risk.

Major Interactions (Avoid)

• Concurrent IV iron products: may cause iron overload.
• Erythropoiesis‑stimulating agents: combined use can exacerbate hypertension.

Moderate Interactions (Monitor Closely)

• Oral phosphate binders: may reduce iron absorption if given shortly after infusion.
• Antacids containing magnesium or aluminum: can affect serum iron measurements.
• Certain antibiotics (e.g., tetracyclines, fluoroquinolones): iron can chelate and reduce antibiotic efficacy.
