Tardyferon (Ferrous Sulfate): Uses, Side Effects, Dosage

Tardyferon is an iron supplement (ferrous sulfate (II) or ferric sulfate) and belongs to the class of compounds known as inorganic transition metal sulfates and it is used to treat or prevent low iron levels in the blood (for example, for anemia or during pregnancy). Iron is an important mineral that the body needs to make and keep red blood cells healthy.

Mechanism of action of iron sulfate

Iron (II) sulfate replaces the iron stores found in hemoglobin in red blood cells, myoglobin and other heme enzymes in the body. In addition, iron sulfate allows the transport of oxygen by hemoglobin.
Most of the stored iron is bound to the ferritin protein. As it is transmitted to the body, Fe2 + iron is converted to Fe3 + by ceruloplasmin so that it can bind to the transferrin protein.
