Summary
Triamterene is a potassium-sparing diuretic that tends to reduce urinary magnesium loss. Serum magnesium may rise slightly, which is seldom significant except in renal impairment with magnesium supplementation.
What this interaction means in plain words
Magnesium 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 belongs to Gastrointestinal Tract; Triamterene belongs to Cardiovascular.
Why it happens
Blockade of epithelial sodium channels in the distal nephron may reduce renal magnesium wasting.
What to do
No routine action is needed. Check serum magnesium in patients with reduced renal function who take magnesium supplements with triamterene.
