Can You Take Calcium and Spironolactone Together?

No documented interaction was identified between calcium and spironolactone in the sources reviewed.

No documented interaction identifiedEvidence: Moderate

What the interaction means

Spironolactone's FDA label mentions "calcium" only inside its generic pharmacologic-class taxonomy list (e.g., "calcium channel blocker"), not as an interaction statement. Calcium's own NIH fact sheet does not mention spironolactone.

No documented interaction 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

The label's taxonomy-list mentions of "calcium" are a reference vocabulary, not a genuine interaction claim, so they are deliberately not treated as one here -- both substances' own current authoritative sources were checked directly, in both directions.
