Interactions between Ferric derisomaltose and Vitagen Forte

Generally avoid

Parenteral iron therapy may reduce the absorption of concomitantly administered oral iron preparations.

Management

Parenteral iron preparations should not be administered concomitantly with oral iron preparations. Patients should wait at least 5 days after stopping parenteral iron therapy before taking oral iron supplements.

The recommended maximum number of medicines in the 'iron preparations' category to be taken concurrently is usually one. Your list includes two medicines belonging to the 'iron preparations' category:

• ferric derisomaltose
• Vitagen Forte (multivitamin with iron)

Note: In certain circumstances, the benefits of taking this combination of drugs may outweigh any risks. Always consult your healthcare provider before making changes to your medications or dosage.

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.
