For this reason, triamterene is called a potassium sparing diuretic. By combining hydrochlorothiazide with triamterene, sodium and water are eliminated from the body without the loss of potassium. However, this drug may allow potassium levels to increase so potassium levels should be closely monitored.
How does Lasix affect potassium levels?
Hyperglycemia is also a common side effect. The tendency, as for all loop diuretics, to cause low serum potassium concentration (hypokalemia) has given rise to combination products, either with potassium itself (e.g. Lasix-K and Diumide-K Continus) or with the potassium-sparing diuretic amiloride (Co-amilofruse).
Can hydrochlorothiazide cause low potassium?
These may be symptoms of a condition called hypokalemia or potassium loss. Hydrochlorothiazide can lower potassium levels. While taking hydrochlorothiazide, you may need to take potassium supplements, decrease salt intake, and eat a diet rich in potassium with foods like bananas.
