Summary
Oral iron and trientine chelate each other in the gut, so both iron absorption and trientine's copper-lowering effect may fall. Iron-trientine complexes are also poorly absorbed and can be toxic to the gut.
What this interaction means in plain words
Ferrous fumarate and Trientine can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Ferrous fumarate belongs to Miscellaneous; Trientine belongs to Miscellaneous.
Why it happens
Trientine chelates iron in the gastrointestinal tract, forming poorly absorbed complexes that reduce absorption of both agents.
What to do
Give iron at least 2 hours apart from trientine. Monitor copper indices in Wilson disease and iron indices in the patient.
