Monofer (Ferric Derisomaltose)

Monofer, an intravenous iron supplement, is used to correct iron deficiency anemia by replenishing body iron stores.

• Iron deficiency anemia in chronic kidney disease: increases hemoglobin and replenishes iron stores.
• Iron deficiency anemia in inflammatory bowel disease: restores iron balance and reduces fatigue.
• Iron deficiency anemia in postpartum patients: rapidly corrects anemia and supports recovery.

• Ferric derisomaltose is a stable iron‑carbohydrate complex that, after intravenous infusion, is taken up by macrophages of the reticulo‑endothelial system. Within these cells the complex releases bioavailable iron, which binds to transferrin and becomes available for incorporation into hemoglobin and iron‑dependent enzymes, thereby correcting iron deficiency. The controlled release minimizes free‑iron exposure, reducing oxidative stress and allowing a single high‑dose administration.

Ferric derisomaltose may be associated with a range of adverse reactions, which are categorized by frequency.

Common Side Effects

• Nausea: mild to moderate feeling of sickness.
• Headache: transient cranial discomfort.
• Injection site pain: discomfort at the infusion site.

Serious or Rare Side Effects

• Anaphylaxis: severe allergic reaction requiring immediate medical attention.
• Hypotension: marked drop in blood pressure with symptoms.
• Iron overload: excessive iron accumulation in organs.

When using Monofer, several precautions should be observed to ensure patient safety and product integrity.

• Assess iron status: confirm iron deficiency before administration.
• Monitor hemoglobin: check levels during and after treatment.
• Observe for hypersensitivity: watch for signs of allergic reaction during infusion.
• Use appropriate infusion rate: follow recommended administration guidelines to reduce adverse events.
• Avoid use in patients with known hypersensitivity to ferric derisomaltose or its components.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Ferric derisomaltose can interact with certain medicines, affecting iron availability or increasing the risk of adverse effects.

Major Interactions (Avoid)

• Concurrent IV iron products: may cause iron overload.
• High-dose vitamin C supplements: increase free iron absorption and oxidative stress.

Moderate Interactions (Monitor Closely)

• Erythropoiesis‑stimulating agents: may enhance hematologic response, requiring dose adjustment.
• Oral phosphate binders: can bind iron and reduce its absorption if given close to infusion.
• Certain antibiotics (e.g., tetracyclines, quinolones): may chelate iron, reducing efficacy.
