Is Zinc Safe with Prednisone?
Free · No account · based on published sources including NIH ODS, FDA drug labels, and peer-reviewed literature
Discuss zinc supplementation with your physician if you are on long-term prednisone. Avoid high-dose zinc supplementation without medical supervision as excess zinc can impair immune function and copper absorption.
Why this interaction occurs
Chronic corticosteroid use increases urinary zinc excretion, potentially contributing to zinc deficiency. Zinc plays a critical role in wound healing and immune function, both of which are already compromised by prednisone. Modest supplementation may be beneficial but should be medically supervised.
Evidence
Evidence level: moderate.
