What the interaction means

Zinc's own NIH fact sheet interactions section names only quinolone antibiotics, tetracycline antibiotics, penicillamine, and thiazide diuretics -- levothyroxine is not among them. Levothyroxine's own extensive drug-interaction section does not name zinc.

No documented interaction between Levothyroxine and Zinc was identified in the authoritative sources reviewed. This is not a guarantee that no interaction exists for every dose, formulation, or individual -- it means the sources checked did not document one.

Practical context

Zinc's NIH ODS fact sheet and levothyroxine's FDA label were checked directly, full text, in both directions. Neither source names the other.
