Summary
Trientine chelates iron in the gut, lowering absorption of both trientine and iron. Iron deficiency can result, and trientine efficacy in Wilson disease may be reduced.
What this interaction means in plain words
Iron 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.
Iron belongs to Gastrointestinal Tract; Trientine belongs to Miscellaneous.
Why it happens
Chelation of iron by trientine in the gastrointestinal tract forms poorly absorbed complexes.
What to do
Separate oral iron from trientine by at least 2 hours. Monitor iron indices and copper control during combined therapy.
