What is the formula for parenteral iron therapy in adults?
Parenteral iron therapy needs calculation of the iron requirement of the patient. Iron requirement (mg) = 4.4 x body weight (kg) x Hb deficit (g/dl). This formula includes iron needed for replenishment of stores. Iron stores can be replenished in a shoer time by parenteral therapy.
