How does this medication work? What will it do for me?
Iron dextran belongs to a class of medications known as iron supplements. It is an injectable form of iron that is used to treat iron-deficiency anemia when oral iron supplements cannot be taken or when oral iron supplements have not produced the needed results.
Iron is important for the production of red blood cells. It helps red blood cells to carry oxygen to the various parts of the body.

How should I use this medication?
Iron dextran is usually injected into a muscle in the buttocks by a doctor or qualified health care professional. In some circumstances, it is given intravenously (into a vein) in the hospital.
