Summary
Oral iron binds penicillamine in the gut and reduces its absorption, possibly lowering effectiveness. Stopping iron on stable penicillamine therapy may raise penicillamine exposure.
What this interaction means in plain words
Penicillamine and Polysaccharide iron 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.
Why it happens
Chelation of penicillamine by iron in the gastrointestinal tract reduces absorption.
What to do
Separate doses by at least 2 hours and monitor clinical response to penicillamine.
