Documented concern based on cited evidence — not a personalized safety check, not medical advice, and not a decision to combine or avoid. That decision belongs with your prescriber.
Low-grade concern — timing, disclosure, or lab context
Low-grade documented concern. Timing, disclosure, or a lab context decides whether it matters for you.
Mechanism and evidence
Diuretics waste magnesium, so replacement is often reasonable. With normal kidney function, hypermagnesemia from standard oral doses is rare, and high doses more often cause diarrhea. In chronic kidney disease the risk of magnesium accumulation, and with it hypermagnesemia, rises.
Evidence tier: pharmacology-standard
No single PMID anchors this pair: the grading rests on established pharmacology (label practice and clinical standard) as agreed with the reviewer.
What to discuss with your prescriber
- Let your doctor pick the magnesium dose based on labs and kidney function.
- Report slow pulse, flushing, or confusion.
