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: The presence of certain foods (e.g., bread, bran, hard boiled eggs, coffee, and milk) may significantly delay the absorption of zinc acetate. Fibres, phytates, and other substances in food prevent zinc from entering intestinal cells by binding with it. Protein does not appear to interfere with its absorption.

MANAGEMENT: Zinc acetate should preferably be taken on an empty stomach, at least one hour before or two to three hours after meals. It may be taken with small amounts of protein such as meat.
