Suggest patient take vitamin C with drug. Drug-food: Cereals, cheese, coffee, eggs, milk, tea, whole-grain breads, yogurt: May impair iron absorption. Advise against use together. Assessment:

Obtain baseline assessment of patient’s iron deficiency before starting therapy. Evaluate hemoglobin level, hematocrit, and reticulocyte count during therapy. Asses patient’s and family’s knowledge of drug therapy.

Implementation:

Give tablets with juice or water, but not with milk or antacids. Dilute liquid forms in juice or water, but not with milk or antacids. Don’t crush or allow patient to chew extended-release forms. Be alert for adverse reactions and drug intereactions.If patient misses a dose, tell the patient to take it as soon as he remembers but not to double the dose. Advise patient to avoid taking drug with certain foods that may impair oral iron absorption, including yogurt, cheese, eggs, milk, whole-grain breads and cereals, tea, and coffee. Teach dietary measures for preventing constipation.
