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.

A blood transfusion is a routine medical procedure in which donated blood is provided to you through a narrow tube placed within a vein in your arm. This potentially life-saving procedure can help replace blood lost due to surgery or injury.

Intravenous antibiotics are antibiotics that are administered directly into a vein so that they can enter the bloodstream immediately and bypass the absorption in the gut.
