Monoferric (Ferric Derisomaltose) Dosing for Iron Deficiency Anemia
Ferric derisomaltose (Monoferric) should be administered as a single intravenous infusion of 1000 mg for most patients with iron deficiency anemia, which can effectively replenish iron stores in a single treatment session. 1
Dosing Guidelines
The recommended dose of ferric derisomaltose is based on body weight and hemoglobin level: 2
- For patients weighing <70 kg:
- Hemoglobin 10-12 g/dL (women) or 10-13 g/dL (men): 1000 mg
- Hemoglobin 7-10 g/dL: 1500 mg
- For patients weighing ≥70 kg:
- Hemoglobin 10-12 g/dL (women) or 10-13 g/dL (men): 1500 mg
- Hemoglobin 7-10 g/dL: 2000 mg
- For patients weighing <70 kg:
Ferric derisomaltose can be administered as a single high-dose infusion up to 1000 mg, making it more convenient than multiple smaller doses of other IV iron formulations 3, 4
For patients with severe iron deficiency anemia, studies suggest that a cumulative dose of 1500 mg may be closer to the actual iron deficit than the standard 1000 mg dose 5
Administration Method
Ferric derisomaltose should be administered as an intravenous infusion over 15-30 minutes 1
No test dose is required before administration, unlike with iron dextran preparations 2, 3
Resuscitation facilities should be available during administration due to the small risk of hypersensitivity reactions 2
Indications for IV Iron Therapy
- Intravenous iron therapy with ferric derisomaltose is indicated for patients with: 2
- Intolerance to oral iron therapy
- Inadequate response to oral iron therapy
- Need for rapid iron repletion
- Hemoglobin below 10 g/dL
- Active inflammatory bowel disease
- Chronic kidney disease with iron deficiency anemia
Monitoring and Follow-up
After iron repletion, hemoglobin concentration and red cell indices should be monitored at 3-month intervals for the first year, then after another year 2
Iron status should be re-evaluated 3 months after treatment, not earlier (especially within 4 weeks) as ferritin levels are markedly increased immediately following IV iron administration 2
Additional iron repletion should be provided as needed based on follow-up testing 2
Safety Considerations
Ferric derisomaltose has a favorable safety profile with a lower incidence of hypophosphatemia compared to some other IV iron formulations 4
Cardiovascular adverse events may be less frequent with ferric derisomaltose compared to iron sucrose, which is particularly important for patients with heart failure 1, 6
Contraindications include: 2
- Hypersensitivity to the active substance or any excipients
- Known serious hypersensitivity to other parenteral iron products
- Anemia not attributed to iron deficiency
- Evidence of iron overload or disturbances in iron utilization
Clinical Benefits
Ferric derisomaltose provides a faster hematological response compared to multiple doses of iron sucrose 1
In patients with heart failure and iron deficiency anemia, ferric derisomaltose improves quality of life and may decrease cardiovascular events 6
The percentage of patients requiring retreatment is significantly lower with higher cumulative doses (1500 mg vs 1000 mg) 5
