Iron infusion is a procedure in which iron is delivered to your body intravenously, meaning into a vein through a needle. This method of delivering medication or supplementation is also known as an intravenous (IV) infusion.
Iron infusions are usually prescribed by doctors to treat iron deficiency anemia. Iron deficiency anemia is typically treated with dietary changes and iron supplements that you take in pill form. In some cases, though, doctors may recommend iron infusions instead.
You may require an IV infusion if you:
can’t take iron by mouth
can’t absorb iron adequately through the gut
can’t absorb enough iron due to blood loss
need to increase iron levels fast to avoid medical complications or a blood transfuse
