Can You Take Magnesium and Spironolactone Together?

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

No documented interaction identifiedEvidence: Moderate

What the interaction means

Spironolactone's FDA label mentions "magnesium" only as "magnesium stearate" (an inactive tablet excipient) and inside its generic taxonomy dropdown -- not an interaction statement. Magnesium'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

Both substances' own current authoritative sources were checked directly, full text, in both directions; the inactive-ingredient and taxonomy-list mentions were deliberately not treated as a real interaction claim.
