During the first four hours, less than 5% of iron is excreted by the kidneys. For 24 hours, about 75% of sucrose is removed, the iron is removed completely.

Indications for use

Venofer is prescribed for conditions accompanied by iron deficiency in the body. Namely:

  • To quickly restore the concentration of iron;
  • With intolerance of oral iron or non-compliance with the prescribed treatment regimen;
  • When iron-containing oral agents are ineffective due to the presence of intestinal diseases.

Contraindications

Contraindicated Venofer at:

  • Violations of the process of iron utilization;
  • Symptoms of an excess of iron (hemochromatosis, hemosiderosis);
  • Individual intolerance to the components of the drug;
  • In the first trimester of pregnancy.

Dosing and Administration

The solution is administered only intravenously (by drip / jet) or into the venous section of the dialysis system.

The solution is not intended for intramuscular injection.

A complete therapeutic dose of the drug can not be administered concurrently.

 

Ampoules must be checked for damage before opening and the solution for sediment. Use only a brown solution without any foreign particles and inclusions.

Before the first administration of Venofer, a test dose is given: 20 mg of iron (1 ml) is administered to adults and children weighing more than 14 kg or 1.5 mg / kg for children weighing less than 14 kg. The infusion lasts no less than 15 minutes. When intolerance reactions occur, the administration is immediately stopped. If unwanted side effects do not develop, the remaining solution is administered at the recommended rate.

Drip introduction

Immediately prior to infusion, the venofer is diluted with 0.9% sodium chloride solution in a ratio of 1:20 (per 1 ml of the drug, 20 ml of sodium chloride).

The rate of infusion is determined by the dosage of iron: 100 mg of iron is administered at least 15 minutes, 200 mg of iron for 30 minutes, 300 mg of iron for 1.5 hours, 400 mg for 2.5 hours, 500 mg for 3.5 hours.

Calculation of the doses of Venofer

In conditions accompanied by a lack of iron in the body, the dose of the drug is calculated individually for each patient based on the total iron deficiency by the formula: the total volume of the venofer solution to be introduced = total iron deficiency / 20 mg / ml.

To restore the content of iron after blood loss or blood donation (if the amount of blood lost is known), the Venofer dose is calculated using the formula: necessary volume of Venofer (ml) = number of units of lost blood * 10.

Standard dosages of the VENOFER

Adults and elderly patients are usually prescribed 100-200 mg of iron (5-10 ml of solution) from 1 to 3 times per week (based on the hemoglobin content).
