My pharmacist tells me potassium sparing diuretics such as spironolactone are not completely, potassium sparing. is this true?

Diuretics potassium: Potassium is excreted by the kidney in patients on sodium losing diuretics like Furosemide and hctz there is potassium wasting some of this loss can be decreased by low salt diets in patients who have low potassium u can offset this by drugs such as Aldactone (spironolactone) this is not a total block but if using Aldactone (spironolactone) check levels of potassium low potassium in absence. Of cause should be investigated.

Possible: Potassium sparing diuretics tend to decrease the amount of potassium elimanted by kidneys . If a patient needs to take diuretics due to fluid retention if potassium is low will choose a potassium sparing diuretic like spironolactone . There is still potassium eliminated in the urine , in smoller ammounts.
