  • Penicillamine· chelator

    Zinc can interfere with the effectiveness of penicillamine.

    → Avoid concurrent use; consult a healthcare provider.

    HIGH

  • Antibiotics· tetracycline

    Zinc can bind to tetracycline antibiotics, reducing their absorption.

    → Space zinc and antibiotic doses by at least 2 hours.

    MODERATE

  • Diuretics· thiazide

    Thiazide diuretics can increase zinc excretion, potentially leading to deficiency.
