Summary

Trientine chelates copper and promotes its elimination, which is the intended therapeutic effect in Wilson's disease. Copper supplementation would oppose this, and excessive treatment can cause copper deficiency.

What this interaction means in plain words

Copper 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.

Copper belongs to Gastrointestinal Tract; Trientine belongs to Miscellaneous.

Evidence level: High

Why it happens

Trientine chelates copper, increasing urinary excretion and limiting absorption.

What to do
