Free · No account · based on published sources including NIH ODS, FDA drug labels, and peer-reviewed literature
Avoid over-the-counter potassium supplements. Follow a potassium-controlled diet as advised by your healthcare team. Monitor potassium levels at every clinic visit and report signs of hyperkalemia such as fatigue, weakness, or numbness.
Why this interaction occurs
Cyclosporine causes hyperkalemia through multiple mechanisms including inhibition of aldosterone secretion, reduction in renal tubular potassium excretion, and nephrotoxicity-related reduction in glomerular filtration rate. Additional potassium supplementation significantly increases the risk of hyperkalemia-induced cardiac complications in transplant patients.
Evidence
Evidence level: moderate.
