NOTE: Even iron-rich foods are poorly absorbed by humans. Only
about 10% of food iron is absorbed from food consumed by an
individual with normal iron stores. However, an iron-deficient
person, may absorb 20 to 30%.
REASONS TO USE
Prevents and treats iron-deficiency anemia due to dietary iron
deficiency or other causes. Iron dextran is particularly useful
for people who develop severe gastrointestinal symptoms when
they take iron orally.
Stimulates bone-marrow production of hemoglobin, the
red-blood-cell pigment that carries oxygen to body cells.
Forms part of several enzymes and proteins in the body.
UNPROVED SPECULATED BENEFITS
Controls alcoholism.
Helps alleviate menstrual discomfort.
Stimulates immunity.
Boosts physical performance.
Prevents learning disorders in children.
WHO NEEDS ADDITIONAL AMOUNTS?
Many women of child-bearing age are mildly iron-deficient even
when they get all their nutritional requirements.
Anyone with inadequate caloric or dietary intake or increased
nutritional requirements.
Older people (over 55 years).
Pregnant or breast-feeding women.
Women with heavy menstrual flow, long menstrual periods or
short menstrual cycles.
Those who abuse alcohol or other drugs.
People with a chronic wasting illness, excess stress for long
periods or those who have recently undergone surgery.
Athletes and workers who participate in vigorous physical
activities.
Those with a portion of the gastrointestinal tract surgically
removed.
Patients with recent severe burns or injuries.
Anyone who has lost blood recently, such as from heavy
menstrual periods or from an accident.
Vegetarians.
Infants from 2 to 24 months.
DEFICIENCY SYMPTOMS
Listlessness
Heart palpitations upon exertion

None
LAB TESTS TO DETECT DEFICIENCY

DOSAGE AND USAGE INFORMATION
Lactating |
+30-60mg |
What this mineral does: |
>Iron is an essential component of hemoglobin, myoglobin and a |
co-factor of several essential enzymes. Of the total iron in the |
body, 60 to 70% is stored in hemoglobin (the red part of red |
blood cells). |
>Hemoglobin is also a component of myoglobin, an iron-protein |
complex in muscles. This complex helps muscles get extra energy |
when they work hard. |
Miscellaneous information:
Iron-deficiency anemia in older men is usually considered to
be due to slow loss of blood from a malignancy in the
gastrointestinal tract until proved otherwise.
Iron content of foods, especially acidic foods, can be
dramatically increased by preparation in iron cookware.
May require 3 weeks of treatment before you receive maximum
benefit.
Works best with vitamin C (ascorbic acid).
Available as:
Injectable forms are administered by doctor or nurse.
WARNINGS AND PRECAUTIONS
Don't take if you:
Are allergic to any iron supplement.
Have acute hepatitis.
Have hemosiderosis or hemochromatosis (conditions involving
excess iron in body).
Have hemolytic anemia.
Have had repeated blood transfusions.
Consult your doctor if you have:
Plans to become pregnant while taking medication.
Had stomach surgery.
Had peptic-ulcer disease, enteritis, colitis.
Had pancreatitis or hepatitis.
Alcoholism.
Kidney disease.
Rheumatoid arthritis.
Intestinal disease.
Over age 55:
Deficiency more likely. Check frequently with doctor for
anemia symptoms or slow blood loss in stool.
Pregnancy:
Pregnancy increases need. Check with doctor. During first 3
months of pregnancy, take ONLY if doctor prescribes it.
Don't take megadoses.
Breast-feeding:
Supplements probably not needed if you are healthy and eat a
balanced diet.
Baby may need supplementation. Ask your doctor.
Don't take megadoses.
Effect on lab tests:
May cause abnormal results in serum bilirubin, serum calcium,
serum iron, special radioactive studies of bones using
technetium (Tc 99m-labeled agents), stool studies for blood.
Storage:
Store in cool, dry place away from direct light, but don't
freeze.
Store safely out of reach of children. Iron tablets look like
candy, and children love them.
Don't store in bathroom medicine cabinet. Heat and moisture
may change action of mineral.
Others:
Iron can accumulate to harmful levels (hemosiderosis) in
patients with chronic kidney failure, Hodgkins disease,
rheumatoid arthritis.
Prolonged use in high doses can cause hemochromatosis
(iron-storage disease), leading to bronze skin, diabetes, liver
damage, impotence, heart problems.
Intramuscular iron can leave unsightly black deposits in skin
that mimic tattoo marks.
OVERDOSE/TOXICITY
Signs and symptoms:
EARLY SIGNS: Diarrhea with blood, severe nausea, abdominal
pain, vomiting with blood.
LATE SIGNS: Weakness, collapse, pallor, blue lips, blue hands,
blue fingernails, shallow breathing, convulsions, coma, weak,
rapid heartbeat.
What to do:
For symptoms of overdosage: Discontinue mineral, and consult
doctor. Also see ADVERSE REACTIONS OR SIDE EFFECTS section
below.
For accidental overdosage (such as child taking entire
bottle): Dial 911 (emergency), 0 for operator or your nearest
Poison Control Center.
