Summary
Triamterene is a potassium-sparing diuretic that tends to reduce urinary magnesium loss. With regular magnesium intake or renal impairment this could contribute to higher magnesium levels, though the effect is usually small.
What this interaction means in plain words
Magnesium citrate and Triamterene have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Magnesium citrate belongs to Gastrointestinal Tract; Triamterene belongs to Cardiovascular.
Why it happens
Blockade of epithelial sodium channels reduces renal magnesium excretion.
What to do
No action is needed for occasional laxative use with normal renal function. Monitor serum magnesium if magnesium products are taken regularly or kidney function is reduced.
