Iron deficiency, or sideropenia, is the state in which a body lacks enough iron to supply its needs. Iron is present in all cells in the human body and has several vital functions, such as carrying oxygen to the tissues from the lungs as a key component of the hemoglobin protein, acting as a transport medium for electrons within the cells in the form of cytochromes, and facilitating oxygen ...
Methemoglobinemia can be due to certain medications, chemicals, or food or it can be inherited. [2] Substances involved may include benzocaine , nitrites , or dapsone . [ 3 ] The underlying mechanism involves some of the iron in hemoglobin being converted from the ferrous [Fe 2+ ] to the ferric [Fe 3+ ] form. [ 3 ]

Iron deficiency can also cause shortness of breath, and amplify the symptoms of any chronic condition, such as depression. It can also have an affect on your mood, ability to focus and sleep quality.
Many drugs have been implicated in causing oxidative damage to RBCs, which may cause a hemolytic anemia especially if these drugs are used in individuals with compromised antioxidant mechanisms such as G6PD deficiency or Hemoglobin H disease. Drugs commonly implicated in causing hemolytic anemia in these individuals include [1]: Primaquine; Dapsone
