Summary
Telmisartan reduces aldosterone-mediated potassium excretion, and potassium supplements add to the potassium load. Hyperkalemia may result, especially in renal impairment, diabetes or older age.
What this interaction means in plain words
Potassium citrate / citric acid and Telmisartan-amlodipine 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.
Why it happens
Angiotensin receptor blockade lowers aldosterone-driven renal potassium excretion, adding to exogenous potassium intake.
What to do
Monitor serum potassium and renal function after starting and periodically during therapy. Adjust or stop the potassium product if potassium rises.
