Iron–Dextran is primarily used in medical and veterinary fields to treat iron deficiency anemia. It is administered via injection, making it particularly effective for patients who cannot absorb iron efficiently through oral supplements. In humans, it is often prescribed for individuals with chronic kidney disease, those undergoing dialysis, or patients with gastrointestinal disorders that impair iron absorption. In veterinary medicine, it is commonly used to treat anemia in livestock, especially in piglets and young animals, ensuring healthy growth and development. The compound works by replenishing iron stores in the body, promoting the production of hemoglobin and improving overall oxygen transport in the blood. Its dextran component helps in slow release, reducing the risk of toxicity and ensuring sustained therapeutic effects.
