Question: what blood pressure medications lower potassium?
Answer: Two of the major classes, thiazide diuretics and loop diuretics, tend to lower potassium levels in the blood. But drugs in the other class, potassium-sparing diuretics, tend to raise potassium levels in the blood. Examples of these include spironolactone (Aldactone, generic) and triamterene (Dyrenium, generic).
