Potassium-Sparing Diuretics Cyclosporine should not be used with potassium-sparing diuretics because hyperkalemia can occur.
Caution is also required when cyclosporine is coadministered with potassium sparing drugs (e.g., angiotensin converting enzyme inhibitors, angiotensin II receptor antagonists), potassium-containing drugs as well as in patients on a potassium rich diet.
If hypertension persists, the dose of Neoral should be further reduced or blood pressure should be controlled with antihypertensive agents.
