ADJUST DOSING INTERVAL: The bioavailability of orally administered iron may be reduced by concomitant administration of antacids or other agents with acid-neutralizing effects. The exact mechanism is unknown but may involve reduced iron solubility due to increase in gastric pH and/or reduced absorption due to complexation or precipitation of the iron. Based on existing data, sodium bicarbonate and calcium carbonate appear to have greater effects than antacids containing magnesium and aluminum hydroxides. In a study of patients with mild iron deficiency anemia, coadministration of ferrous sulfate with sodium bicarbonate 1 gram and calcium carbonate 500 mg reduced iron absorption by 50% and 67%, respectively, while 5 mL of an antacid containing magnesium and aluminum hydroxides had little effect. Another study also found no effect on iron absorption when ferrous sulfate (equivalent to 10 mg/kg of elemental iron) was coadministered with magnesium hydroxide (1 mg for every 5 mg of elemental iron ingested) in a group of healthy, fasting male subjects. In contrast, absorption of iron from ferrous sulfate and ferrous fumarate tablets was reduced by 37% and 31%, respectively, following administration of an antacid containing magnesium carbonate, magnesium hydroxide, and aluminum hydroxide in a study of healthy, iron-replete volunteers. Similarly, in a study of nine patients, coadministration of 5 mg of ferrous sulfate with a 35 gram dose of magnesium trisilicate was found to reduce iron absorption by an average of more than 70%. The interaction reportedly does not occur in the presence of ascorbic acid, which may competitively bind with iron and prevent the interference with iron absorption.
MANAGEMENT: To minimize the potential for interaction, it may be appropriate to administer oral iron preparations at least two hours apart from antacids or other agents with acid-neutralizing effects.

Drug and food interactions
multivitamin, prenatal food
Applies to: Prenaissance Next (multivitamin, prenatal)
ADJUST DOSING INTERVAL: Concomitant use of some oral medications may reduce the bioavailability of orally administered iron, and vice versa.
Food taken in conjunction with oral iron supplements may reduce the bioavailability of the iron. However, in many patients intolerable gastrointestinal side effects occur necessitating administration with food.
MANAGEMENT: Ideally, iron products should be taken on an empty stomach (i.e., at least 1 hour before or 2 hours after meals), but if this is not possible, administer with meals and monitor the patient more closely for a subtherapeutic effect. Some studies suggest administration of iron with ascorbic acid may enhance bioavailability. In addition, administration of oral iron products and some oral medications should be separated whenever the bioavailability of either agent may be decreased. Consult the product labeling for specific separation times and monitor clinical responses as appropriate.
