Reserve parenteral iron for patients who are either unable to absorb oral iron or who have increasing anemia despite adequate doses of oral iron. It is expensive and has greater morbidity than oral preparations of iron. Parenteral iron has been used safely and effectively in patients with inflammatory bowel disease (eg, ulcerative colitis, Crohn disease), [27] as the ferrous sulfate preparations may aggravate the intestinal inflammation.
