Before the first injection of Venofer, a test dose is administered: 20 mg of iron (1 ml) is administered to adults and children weighing more than 14 kg or 1.5 mg / kg to children weighing less than 14 kg. When this infusion lasts at least 15 minutes. In the event of intolerance reactions, the administration immediately stops. If undesirable side effects do not develop, the remaining solution is injected at the recommended rate.

Venofer Drip

Immediately before the infusion, Venofer is diluted with a 0.9% solution of sodium chloride in the ratio of 1:20 (20 ml of sodium chloride per 1 ml of the preparation).

The infusion rate 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 - 1.5 hours, 400 mg - 2.5 hours, 500 mg - 3.5 hours.

Calculation of doses Venofer

In conditions involving iron deficiency in the body, the dose of the drug is calculated individually for each patient based on the indicators of total iron deficiency using the formula: total volume of Venofer's solution, which must be entered = total iron deficiency / 20 mg / ml.

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

Venofer Standard Dosages

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

Maximum tolerable single dose
