  5. Drug Interactions
    1. Food and drugs reducing iron absorption
      1. Antacids (raise pH, low acidity)
        1. Tums, Maalox, or Mylanta
        2. Histamine H2 Receptor Blockers (e.g. Ranitidine)
        3. Proton Pump Inhibitors (e.g. Prilosec)
      2. Inhibitors of iron absorption
        1. Polyphenol (in vegetables)
        2. Tannins (in tea)
        3. Phytate (in bran, cereal)
        4. Calcium (dairy products)
    2. Drugs increasing iron absorption
      1. Vitamin C (Ascorbic acid)
    3. Drugs with decreased absorption when taken with iron
      1. Levodopa
      2. Methyldopa
      3. Penicillamine
      4. Quinolones
      5. Tetracyclines
  6. Adverse Effects
    1. Gastrointestinal distress
      1. Ferrous iron causes mucosal irritation
      2. Start with once daily dosing and titrate to tid
      3. Tolerance is directly related to iron concentration
        1. Start with normal concentration elemental iron
          1. Decrease to lower concentrations as needed
        2. Lower elemental iron concentration better tolerated
          1. Ferrous gluconate
          2. More expensive iron preparations
      4. Enteric coated Iron has decreased absorption
    2. Black stools
    3. Hemochromatosis
      1. Prolonged, excessive iron supplementation

Ferrous fumarate (C0060276)

Definition (NCI)The fumarate salt form of the mineral iron. Administration of ferrous fumarate results in elevation of serum iron concentration, which is then assimilated into hemoglobin, required for the transport of oxygen, or trapped in the reticuloendothelial cells for storage. This agent is used as a dietary supplement, and to prevent or treat iron deficiency related syndromes.

ferrous gluconate (C0060277)

Definition (NCI)A form of mineral iron for oral administration, Ferrous Gluconate is absorbed in the stomach and small intestine and combines with apoferritin to form ferritin, which is stored in the liver, spleen, red bone marrow, and intestinal mucosa. Important in transport of oxygen by hemoglobin to the tissues, iron is also found in myoglobin, transferrin, and ferritin, and is as a component of many enzymes such as catalase, peroxidase, and cytochromes.
