Summary

Thiazide-like diuretics such as indapamide promote urinary magnesium loss and can cause hypomagnesemia with long-term use. Occasional oral magnesium citrate as a laxative is unlikely to be affected meaningfully, though magnesium status may be lower in chronic users.

What this interaction means in plain words

Indapamide and Magnesium citrate have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.

Indapamide belongs to Cardiovascular; Magnesium citrate belongs to Gastrointestinal Tract.

Evidence level: Moderate

Why it happens

Indapamide increases renal magnesium excretion, which may offset magnesium supplementation.

What to do

No action is needed for occasional laxative use. In long-term indapamide users, check serum magnesium and potassium periodically and supplement if low.
