Several injections treat different types of "blood deficiency," which is a broad term encompassing various conditions. The specific injection depends on the cause of the deficiency.
Iron Deficiency Anemia
For iron deficiency anemia (low red blood cells due to insufficient iron), ferric carboxymaltose injection is one option. This injection is used for adults and children (1 year and older) who can't tolerate or haven't responded to oral iron supplements.
