Introduction
Derisofer IV Injection 500 mg/5 ml is an intravenous iron replacement therapy used to treat iron deficiency anemia in patients who cannot tolerate or have not responded adequately to oral iron supplements. It is a complex of iron with a carbohydrate, which helps in the effective delivery of iron to the body.
Uses
Derisofer IV Injection 500 mg/5 ml is used primarily for:
- Treating iron deficiency anemia in adults who have not responded to oral iron therapy
- Addressing iron deficiency in patients with chronic kidney disease, especially those on dialysis
- Managing iron deficiency in patients with inflammatory bowel disease or undergoing certain surgeries

Mechanism of Action
Derisofer IV Injection 500 mg/5 ml provides a stable form of iron that can be readily absorbed and utilized by the body. The iron is released slowly from the carbohydrate complex, allowing for gradual iron absorption. The iron then participates in the synthesis of hemoglobin and other essential functions that require iron.
How Long Does It Take to Work?
The onset of action for Derisofer IV Injection 500 mg/5 ml is relatively quick compared to oral iron supplements. Patients may begin to see improvements in their hemoglobin levels and symptoms of anemia within 2-4 weeks after administration, although full benefits may take longer depending on the individual's response and iron stores.
Absorption
Derisofer IV Injection 500 mg/5 ml is administered intravenously, so it is directly available in the bloodstream without the need for gastrointestinal absorption. The iron is then gradually released from the carbohydrate complex and taken up by the body's tissues.
Route of Elimination
The iron from Derisofer IV Injection 500 mg/5 ml is gradually utilized or stored in the body. Excess iron that is not utilized is primarily excreted through feces, with a minimal amount excreted through urine. The carbohydrate component is metabolized and cleared by the liver.
Dosage
For patients weighing 50 kg or more: Administer 1,000 mg of Ferric Derisomaltose by intravenous infusion over at least 20 minutes as a single dose. Repeat dose if iron deficiency anemia reoccurs.For patients weighing less than 50 kg: Administer Ferric Derisomaltose as 20 mg/kg actual body weight by intravenous infusion over at least 20 minutes as a single dose. Repeat dose if iron deficiency anemia reoccurs.
The dosage of Ferric Derisomaltose is expressed in mg of elemental iron. Each mL of Ferric Derisomaltose contains 100 mg of elemental iron. Only administer Ferric Derisomaltose when personnel and therapies are immediately available for the treatment of serious hypersensitivity reactions
The dosage of Derisofer IV Injection 500 mg/5 ml is individualized based on the severity of iron deficiency and patient needs. The typical dose ranges from 500 mg to 1000 mg of elemental iron administered intravenously. The dose is often given as a single infusion or in divided doses, depending on the clinical situation and patient tolerance.
Administration
Derisofer IV Injection 500 mg/5 ml is administered intravenously, usually through an infusion. The infusion rate is generally slow to minimize the risk of adverse reactions. The healthcare provider will determine the appropriate infusion rate and duration based on the patient's condition and response.
Side Effects

- Injection site reactions such as pain, swelling, or redness
- Headache
- Nausea
- Dizziness
Toxicity
Iron toxicity is a concern with any iron supplement, particularly in cases of overdose or excessive dosing. Symptoms of iron toxicity can include gastrointestinal distress, liver damage, and systemic reactions. Monitoring and dose adjustment are crucial to prevent toxicity.
Precautions
- Use with caution in patients with a history of allergic reactions to iron products. - Monitor for signs of iron overload, especially in patients with repeated doses or underlying conditions that affect iron metabolism. - Regular blood tests are recommended to assess iron levels and hemoglobin status.
