Drug Interaction Report

ADJUST DOSING INTERVAL: Deferiprone has the potential to bind polyvalent cations such as aluminum, iron and zinc, which may reduce its effectiveness. However, concurrent use with foods, mineral supplements, or antacids that contain polyvalent cations has not been studied.

MANAGEMENT: A minimum 4-hour interval is recommended between the administration of deferiprone and mineral supplements or oral medications that contain antacids (e.g., didanosine buffered tablets or pediatric oral solution) or other polyvalent cations.

ADJUST DOSING INTERVAL: Administration with food may increase the absorption of calcium. However, foods high in oxalic acid (spinach or rhubarb), or phytic acid (bran and whole grains) may decrease calcium absorption.

MANAGEMENT: Calcium may be administered with food to increase absorption. Consider withholding calcium administration for at least 2 hours before or after consuming foods high in oxalic acid or phytic acid.
