Iron–Dextran is primarily used in medical and veterinary fields to treat iron deficiency anemia. It is administered via injection, making it an effective solution for patients who cannot absorb iron efficiently through oral supplements. This compound is particularly beneficial for individuals with chronic blood loss, kidney dialysis patients, or those with gastrointestinal disorders that impair iron absorption. In veterinary medicine, it is commonly used to treat anemia in livestock, especially piglets and young animals, ensuring healthy growth and development. Its formulation allows for controlled release of iron, reducing the risk of toxicity and improving patient outcomes.
