If the anemia is not due to
iron deficiency, taking iron pills will not relieve the anemia and could cause
poisoning (iron toxicity). It could also cause an
iron overload condition called
hemochromatosis, especially in people who have a
genetic tendency toward storing too much iron in their bodies.
some people, iron pills cause stomach discomfort, nausea, diarrhea,
constipation, and black stool. Iron is best absorbed if taken on an empty
stomach. But if you are having stomach problems, you may need to take the pills
with food. Do not take iron pills with milk, caffeinated drinks, or antacids.
If the side effects of your iron pills make you feel too sick, talk to your
doctor. He or she may know of another type of iron pill you can take.
Iron supplement shots can cause side effects. Shots given in a vein
(intravenously, IV) pose the risk of an
allergic reaction. Shots given in the muscle of the
buttock (intramuscularly, IM) may produce permanent marks on the skin that look
like a tattoo.
