Iron–Dextran is primarily used in the medical field for the treatment of iron deficiency anemia. It is administered via injection, making it a suitable option for patients who cannot tolerate oral iron supplements or who have conditions that impair iron absorption. This compound is particularly effective in cases where rapid replenishment of iron stores is necessary, such as in chronic blood loss, pregnancy, or post-surgery recovery. It is also commonly used in veterinary medicine to treat anemia in animals, especially in livestock and pets. The dextran component ensures that the iron is released slowly into the bloodstream, reducing the risk of toxicity and improving the body's ability to utilize the iron effectively.
