What is Ferric carboxymaltose used for?

Ferric carboxymaltose is commonly used to treat “iron-poor” blood (iron deficiency anemia). Low iron levels can occur due to many conditions, including when your body cannot get enough iron from food (because of poor nutrition or poor absorption) or when there is long-term blood loss. Ferric carboxymaltose is a form of injectable iron that is used if you cannot take iron by mouth because of side effects or an unsuccessful response to treatment. It is also used by people who have anemia due to long-term kidney disease.

Iron is an important mineral that your body needs to make enough healthy red blood cells to carry oxygen throughout your body.
