Iron deficiency causes -

Iron is absorbed in the small intestine duodenum and first part of the jejunum. This means that enteric-coated iron tablets may not work as well. If you take antacids, you should take iron tablets two hours before or four hours after the antacid. Vitamin C ascorbic acid improves iron absorption, and some doctors recommend that you take mg of vitamin C with iron tablets.

Possible side effects of iron tablets include abdominal discomfort, nausea, vomiting, diarrhea, constipation, and dark stools. In some cases your doctor may recommend intravenous IV iron. IV iron may be necessary to treat iron deficiency in patients who do not absorb iron well in the gastrointestinal tract, patients with severe iron deficiency or chronic blood loss, patients who are receiving supplemental erythropoietin, a hormone that stimulates blood production, or patients who cannot tolerate oral iron.

If you need IV iron, your doctor may refer you to a hematologist to supervise the iron infusions. IV iron comes in different preparations:. Large doses of iron can be given at one time when using iron dextran.

Iron sucrose and ferric gluconate require more frequent doses spread over several weeks. Some patients may have an allergic reaction to IV iron, so a test dose may be administered before the first infusion.

Allergic reactions are more common with iron dextran and may necessitate switching to a different preparation. Severe side effects other than allergic reactions are rare and include urticaria hives , pruritus itching , and muscle and joint pain. Red blood cell transfusions may be given to patients with severe iron-deficiency anemia who are actively bleeding or have significant symptoms such as chest pain, shortness of breath, or weakness.

Transfusions are given to replace deficient red blood cells and will not completely correct the iron deficiency. Red blood cell transfusions will only provide temporary improvement.
