Summary
Potassium chloride with an ARB can cause hyperkalemia, while the thiazide in the combination promotes potassium loss, so the net effect varies. Risk of hyperkalemia is greatest with renal impairment, diabetes or high supplement doses.
What this interaction means in plain words
Eprosartan-hydrochlorothiazide and Potassium chloride can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Eprosartan-hydrochlorothiazide belongs to Cardiovascular; Potassium chloride belongs to Gastrointestinal Tract.
Why it happens
ARB-induced reduction in aldosterone-mediated potassium excretion opposes thiazide kaliuresis while the supplement adds potassium load.
What to do
Check serum potassium and creatinine after initiation and regularly thereafter, and adjust the potassium dose accordingly.
What to ask your pharmacist
- Should I take them at different times of day?
