For patients who have trouble swallowing tablets, consider the use of FERRIPROX Oral Solution (see the prescribing information for FERRIPROX Oral Solution).

Monitoring Ferritin Levels to Assess Efficacy

Monitor serum ferritin concentration every two to three months to assess the effect of FERRIPROX on body iron stores. If the serum ferritin is consistently below 500 mcg/L, consider temporarily interrupting FERRIPROX therapy until serum ferritin rises above 500 mcg/L.

Dosage Modification for Drug Interactions

Allow at least a 4-hour interval between administration of FERRIPROX and other drugs or supplements containing polyvalent cations such as iron, aluminum, or zinc [see Drug Interactions (7.2), Clinical Pharmacology (12.3)].
