1. What is Diafer and what is it used for
Diafer contains a combination of iron and derisomaltose (a chain of sugar molecules). The iron in Diafer is identical to the iron that occurs naturally in the body.
Diafer is used in cases of low iron levels (called "iron deficiency") in patients with chronic kidney disease undergoing dialysis, in whom oral iron preparations cannot be used.
Diafer is used to supplement and maintain iron stores in the body through repeated administration.
2. Important information before taking Diafer
When not to take Diafer
- if you have anemia that is not caused by low iron levels (e.g. hemolytic anemia);
- if you have too much iron in your body (overload) or have difficulty using iron;
- if you are allergic (hypersensitive) to the product or any of the other ingredients of this medicine (listed in section 6);
- if you have had a severe allergic reaction (hypersensitivity) to other injectable iron preparations;
- if you have liver disease.

Diafer and other medicines

Other sources of information
The following information is intended only for healthcare professionals or healthcare workers:
Dosing
Diafer can be administered in a dose of up to 200 mg, with a maximum weekly dose of 1000 mg. If higher doses are required, other iron medicinal products for intravenous use should be used.
The dose of iron should be determined individually for each patient based on the clinical response to treatment, including assessment of hemoglobin saturation, ferritin, and transferrin, treatment with erythropoiesis-stimulating agent (ESA), and ESA dose. Target levels may vary depending on the patient and local guidelines.
Maintenance therapy with intravenous iron may be administered in small doses at regular intervals to maintain stability of iron parameters within a certain range, in order to prevent iron deficiency or a decrease in iron parameters below certain levels.
Children and adolescents:
Diafer is not recommended for use in children under 18 years of age due to insufficient data on safety and efficacy.
Method of administration:
Patients should be closely monitored for subjective and objective signs of hypersensitivity reactions during and after each administration of Diafer.
Diafer should only be administered under the direct supervision of medical personnel trained in the evaluation and treatment of anaphylactic reactions, in a setting equipped with resuscitation equipment. The patient should be monitored for adverse reactions for at least 30 minutes after each administration of Diafer.
Adults and the elderly:
Diafer can be administered as a rapid intravenous injection (bolus) or as an injection directly into the venous arm of the dialyzer. It can be administered undiluted or diluted with up to 20 ml of sterile sodium chloride solution at a concentration of 0.9%.
Diafer should not be administered simultaneously with oral iron preparations, as the absorption of oral iron may be reduced.
